Rectal seepage

:D

Investigation of the pathophysiology of fecal seepage.Rao SS, Ozturk R, Stessman M.
Department of Internal Medicine, Division of Gastroenterology/Hepatology, University of Iowa, Carver College of Medicine, Iowa City, Iowa, USA.

BACKGROUND AND AIM: Unintentional seepage of stool without awareness is common but its pathophysiology is poorly understood. Our aim was to examine the underlying mechanism(s) for fecal seepage. METHODS: We evaluated prospectively 25 patients with fecal seepage, by performing anorectal manometry, balloon expulsion, saline infusion, pudendal nerve latency tests, and symptom assessments and compared their data with 26 fecal incontinence patients and 43 healthy controls. RESULTS: Predisposing factors for fecal seepage were back injury (7), obstetric injury (6), hemorrhoidectomy (3), pelvic radiotherapy (1), and unknown (8). In the seepage group, the resting and squeeze sphincter pressures were lower (p < 0.02) than healthy controls, but higher (p < 0.002) than incontinent group. During straining, the intrarectal pressure and defecation index were lower (p < 0.05) in the seepage group compared to controls; 72% showed dyssynergia and balloon expulsion time was prolonged (p < 0.01). Threshold for first rectal sensation was impaired (p < 0.002) in the seepage group compared to controls and incontinent group. The seepage group retained more (p < 0.001) saline than the incontinent group but pudendal nerve latency time was impaired (p < 0.05) in both patient groups compared to controls. CONCLUSIONS: Anal sphincter function and rectal reservoir capacity were relatively well preserved but most patients with seepage demonstrated dyssynergia with impaired rectal sensation and impaired balloon expulsion. Thus, incomplete evacuation of stool may play a significant role in the pathogenesis of seepage.

Not an official entry, just getting the ball rolling:

Is stapled hemorrhoidopexy safe for the male homosexual patient? Report of a case.Kekez T, Bulic K, Smudj D, Majerovic M.
University Hospital Zagreb, Kispaticeva 12, Zagreb, Croatia.

Stapled hemorrhoidopexy is becoming a widely accepted surgical treatment for third- and fourth-degree hemorrhoids because it is associated with much less postoperative pain than open hemorrhoidectomy. After the procedure, a circular line of staples is left in the anal canal; therefore, there is a risk of penile injury or condom damage during anal intercourse, which increases the risk of exposure to sexually transmitted diseases. We report the case of a male homosexual patient who engaged in anal intercourse after recovering from a stapled hemorrhoidopexy, resulting in condom damage. We did not consider this possibility and neglected to discuss the issue with the patient. With an estimated 2.5% of the general population being exclusive, male homosexuals, it is necessary to inform such patients to refrain from anal intercourse after hemorrhoidopexy, although there are no reports stating how long this restraint should last.

Spontaneous Ovulation in a True Hermaphrodite with Normal Male Phenotype and a Rare 46,XX/47,XXY Klinefelter's Mosaic Karyotype.

Kanaka-Gantenbein C, Papandreou E, Stefanaki K, Fryssira H, Kolialexi A, Sophocleous C, Mavrou A, Kitsiou-Tzeli S, Chrousos GP.
1st Department of Pediatrics, University of Athens, Athens, Greece.

Background: Most true hermaphrodite patients - characterized by the presence of both ovarian and testicular tis- sue - demonstrate ambiguous genitalia and are diagnosed at birth, most commonly bearing a 46,XX karyotype. Patient and Methods: We report on a 13-year-old boy presenting with left scrotal hemorrhage. He had a left inguinal hernia, a palpable testis in the right, normal male external genitalia and significant gynecomastia. During operation, the left gonad and adjacent tissue were removed for histological examination, which revealed the presence of a normal ovary, rich in follicles and a ruptured corpus luteum, suggestive of spontaneous ovulation, with a normal ipsilateral adnexa and semi-uterus. Biopsy of the right gonad revealed a dysgenetic testicle. Endocrinological assessment postoperatively depicted high FSH, pubertal testosterone and low estradiol levels. Cytogenetic analysis in peripheral blood lymphocytes and FISH of the right gonad revealed a 46,XX (70-60%)/47,XXY (30-40%) karyotype, respectively, while molecular analysis verified the presence of SRY and azoospermia factor genes. Conclusion: The importance of full histological, cytogenetic and molecular investigation and of interdisciplinary approach in every single patient with sex differentiation disorders is highlighted by this rare case of spontaneous ovulation in a true hermaphrodite with normal male external genitalia and Klinefelter mosaicism.

Semen quality of fertile US males in relation to their mothers' beef consumption during pregnancy.

Swan SH, Liu F, Overstreet JW, Brazil C, Skakkebaek NE.
Department of Obstetrics and Gynecology, School of Medicine and Dentistry, University of Rochester, 601 Elmwood Avenue, Rochester, NY 14624, USA.

BACKGROUND To look at possible long-term risks from anabolic steroids and other xenobiotics in beef, we examined mens' semen quality in relation to their mother's self-reported beef consumption during pregnancy. METHODS The study was carried out in five US cities between 1999 and 2005. We used regression analyses to examine semen parameters in 387 partners of pregnant women in relation to the amount of beef their mothers reported eating while pregnant. Mothers' beef consumption was also analysed in relation to the son's history of previous subfertility. RESULTS Sperm concentration was inversely related to mothers' beef meals per week (P = 0.041). In sons of 'high beef consumers' (>7 beef meals/week), sperm concentration was 24.3% lower (P = 0.014) and the proportion of men with sperm concentration below 20 x 10(6)/ml was three times higher (17.7 versus 5.7%, P = 0.002) than in men whose mothers ate less beef. A history of previous subfertility was also more frequent among sons of 'high beef consumers' (P = 0.015). Sperm concentration was not significantly related to mother's consumption of other meat or to the man's consumption of any meat. CONCLUSIONS These data suggest that maternal beef consumption, and possibly xenobiotics in beef, may alter a man's testicular development in utero and adversely affect his reproductive capacity.

Exploring the possible link between childhood and adolescent bestiality and interpersonal violence.


University of Tennessee at Chattanooga, 37403, USA. [email protected]

Bestiality is a serious although less frequently occurring form of animal cruelty that may be linked to subsequent aggression against humans. This investigation examines whether a perpetrator's race, childhood residence, education, commission of a personal crime, and the number of personal crimes committed affects acts of bestiality committed during childhood or adolescence among a sample of incarcerated males. The results show that respondents with less education and those who had been convicted of committing crimes against people on one or more occasions were more likely to have had sex with animals during their childhood or adolescence than other respondents in the sample. These findings lend some support to the sexually polymorphous theory that among these perpetrators sex and aggression have become mutually inclusive and that bestiality as a form of animal cruelty may be linked with interpersonal human violence.

Does Prayer Influence the Success of in Vitro Fertilization–Embryo Transfer?

Kwang Y. Cha, M.D., Daniel P. Wirth, J.D., M.S., and Rogerio A. Lobo, M.D.

OBJECTIVE: To assess the potential effect of intercessory prayer (IP) on pregnancy rates in women being treated with in vitro fertilization–embryo transfer (IVF-ET).
STUDY DESIGN: Prospective, double-blind, randomized clinical trial in which patients and providers were not informed about the intervention. Statisticians and investigators were masked until all the data had been collected and clinical outcomes were known. The setting was an IVF-ET program at Cha Hospital, Seoul, Korea. IP was carried out by prayer groups in the United States, Canada and Australia. The investigators were at a tertiary medical center in the United States. The patients were 219 women aged 26–46 years who were consecutively treated with IVF-ET over a four-month period. Randomization was performed after stratification of variables in two groups: distant IP vs. no IP. The clinical pregnancy rates in the two groups were the main outcome measure.
RESULTS: After clinical pregnancies were known, the data were unmasked to assess the effects of IP after assessment of multiple comparisons in a log-linear model. The IP group had a higher pregnancy rate as compared to the no-IP rate (50% vs. 26%, P=.0013). The IP group showed a higher implantation rate (16.3% vs. 8%, P=.0005). Observed effects were independent of clinical or laboratory providers and clinical variables.
CONCLUSION: A statistically significant difference was observed for the effect of IP on the outcome of IVF-ET, though the data should be interpreted as preliminary. (J Reprod Med 2001;46:781–787)

This study contains not only transgenders and phalloplastys, but also the Latissimus Dorsi, so it fits well with the forum!

Neo-phalloplasty with re-innervated latissimus dorsi free flap: a functional study of a novel technique.

Ranno R, Vesely J, Hyza P, Stupka I, Justan I, Dvorak Z, Monni N, Novak P, Ranno S.
Clinic of Plastic and Aesthetic Surgery, St. Anna University Hospital, Masaryk University, Brno, Czech Republic. [email protected]

Twenty two patients with gender dysphoria underwent neo-phalloplasties using a novel technique. Latissimus dorsi musculocutaneus re-innervated free flap was used to allow voluntary rigidity of the neo-penis. From the first 22 patients, 18 have obtained motoric function of reconstructed penis; the "paradox erection" was obtained. 14 patients came for examination after a follow-up period of mean 26.4 months. We evaluated the motility and shape changes of neo-phallus measuring its different size and dimension during relax and muscle contraction. The range of neo-phallus length in relaxed position was between 7 and 17 cm (mean 12.2 cm), its circumference in the same position had a range between 13 and 20 cm (mean 13.7 cm). All patients were able to contract the muscle with an average length reduction of 3.08 cm and an average circumference enlargement of 4 cm. In this study, the dimensions and motility were quantified demonstrating the neo-phallus function and size changes during sexual intercourse.

Transient genital abnormalities in striped hyenas (Hyaena hyaena).

* Wagner AP,
* Frank LG,
* Creel S,
* Coscia EM.

Department of Ecology, Montana State University, Bozeman, MT 59717, USA.

The highly masculinized genitalia of female spotted hyenas Crocuta crocuta is unique among mammals: Crocuta have no external vagina so urination, penile intromission and parturition take place through the clitoris, which mimics a fully erectile male penis. Among hyenids, virilization of external female genitalia has previously been observed only in Crocuta, so functional explanations of masculinization have focused on aspects of social ecology unique to the species. Here we first show that the striped hyena Hyaena hyaena exhibits both unusual similarity in male and female androgen concentrations and transient genital anomalies characterized by a convergence in genital appearance among young males and females. We then evaluate hypotheses regarding the evolution of genital masculinization in the Hyaenidae and other taxa. Hyaena are behaviorally solitary, so discovery of unusual genital development patterns in this species does not support any current evolutionary models for masculinization in Crocuta, which all rely on the trait originating within a highly social species. Some hypotheses can be modified so that masculinization in Crocuta represents an extreme elaboration of a preexisting trait, shared as a homology with Hyaena

A genital hair tourniquet in a 9-year-old girl.

* Alverson B.

Department of Pediatrics, Brown University, Providence, RI 02903, USA. [email protected]

The hair tourniquet is a well-described phenomenon. Typically, a hair or filament becomes tightly wrapped around an appendage, thereby causing swelling, pain, and, in extreme cases, necrosis. Affected areas include fingers, toes, and the genitalia. A case of a 9-year-old girl with a clitoral hair tourniquet is described, and a review of the literature of genital tourniquets in females is presented, with a discussion about potential etiology.The hair-thread tourniquet syndrome is a disease in which a hair or filament becomes wrapped around an end-perfusion appendage, thereby limiting adequate venous and lymphatic drainage of that tissue. This results in hyperemia, swelling and pain. If uncorrected, edema and interstitial pressures may increase to prevent adequate vascular supply, and the affected area can progress to necrosis. We are classically taught that this syndrome primarily affects the fingers, toes, and infantile penis and is an important consideration in the differential diagnosis of the colicky infant. The author presents a case of a prepubescent girl with a genital hair tourniquet.

Can chlamydial conjunctivitis result from direct ejaculation into the eye?

* Rackstraw S,
* Viswalingam ND,
* Goh BT.

Diagnostic Clinic, Moorfields Eye Hospital, City Road, London EC1V 2PD, UK. [email protected]

The majority of cases of chlamydial conjunctivitis are thought to result from autoinoculation by the patient of infected genital secretions from themselves or their sexual partners. We noted that some patients had developed symptoms following direct ejaculation into the affected eye. We describe four cases of chlamydial conjunctivitis following ejaculation of semen directly into the eye, which have not been previously described. In only one case was chlamydia detected in the genital tract. In three cases, there was no evidence of genital chlamydial infection; the sources of the eye infection being either from infected genital material of their sexual partners transferred by hands to the eyes, or more likely from direct ejaculate inoculation. It is likely that this mode of transmission is underestimated as a history of ejaculation into the conjunctiva is not normally asked for.

High-Risk Behaviors in Women Who Use Crack: Knowledge of HIV Serostatus and Risk Behavior.Brewer TH, Zhao W, Metsch LR, Coltes A, Zenilman J.
From the Department of Medicine (T.H.B.) and Department of Public Health and Epidemiology (W.Z., L.R.M., A.C.), University of Miami Miller School of Medicine, Miami, FL; and Department of Medicine, Johns Hopkins School of Medicine (J.Z.), Baltimore, MD.

PURPOSE: To determine whether crack cocaine-using women who are aware of their HIV serostatus have made modifications in risk behaviors, we compared known HIV-positive (HIV+) and HIV-negative (HIV-) users with respect to sexual risk behaviors, prevalence of sexually transmitted infections (STIs) and vaginitis, and correlates of unprotected sex. METHODS: We used a cross-sectional design with street outreach, recruitment, and interviews of sexually active crack cocaine using women. Women received testing for HIV, STIs, and vaginitis. RESULTS: Sixty-one HIV+ and 117 HIV- women were enrolled. HIV+ women were significantly more likely to be African-American. There were no significant differences in drug use, types of sexual partners, number of paying partners, attitudes regarding condoms, or STI diagnoses. HIV+ women were less likely to engage in unprotected sex compared with HIV- women (56% vs. 75%, adjusted odds ratio [AOR], 0.36; 95% confidence interval [CI], 0.13-0.99). Among HIV+ women, unprotected sex was negatively associated with stronger beliefs regarding the protective value of condoms (AOR, 0.07; 95% CI, 0.01-0.67) and concurrent injection-drug use (AOR, 0.19; 95% CI, 0.04-0.99). CONCLUSIONS: Although the majority of crack using HIV+ crack using women in this sample continued to engage in high-risk sexual activities, they were less likely to do so than HIV- women. Interventions targeting this population are needed.

Dog bites to the male genitalia: characteristics, management and comparison with human bites.

Wolf JS Jr, Turzan C, Cattolica EV, McAninch JW.
Department of Urology, University of California School of Medicine, San Francisco 94143-0738.

Dog bites to the external male genitalia occur infrequently. We present 4 new cases and review 4 others described previously. Victims tend to seek medical care quickly. Thus, morbidity is directly related to the severity of the initial wound and delayed infectious complications appear to be minimal. Guidelines for management include irrigation, debridement as necessary, empiric antibiotics, consideration of tetanus and rabies immunization, and primary wound closure or surgical reconstruction. The differences between dog bites and human bites to the genitalia--primarily interval to presentation and subsequent likelihood of infection--are summarized. Measures to prevent dog bites are discussed.

The Hermaphrodite's Dilemma.Leonard JL.
Department of Zoology, University of Oklahoma, Norman 73019.

Given sexual conflict, mating encounters between simultaneous hermaphrodites will conform to a new, conditional, non-zero sum game of strategy, the Hermaphrodite's Dilemma; special cases of which include Prisoner's Dilemma and Game of Chicken. The model predicts that hermaphrodite mating systems will be based on reciprocation with cheating in a preferred sexual role. This model suggests that study of hermaphrodite mating systems will provide direct evidence for the existence of sexual conflict and suggests that sexual conflict may act to stabilize hermaphroditism through such mating systems.

Penile size and the 'small penis syndrome'Wylie KR, Eardley I.
Urology, Royal Hallemshire Hospital, Sheffield, UK.

The male is often troubled by concerns that his penis is not large enough to satisfy his partner or himself. He is ashamed to have others view his penis, especially in the flaccid state. Such concerns might be unfounded in reality and might be a presentation of social anxiety or some other clinical problem, such as erectile dysfunction. Concern over the size of the penis, when such concern becomes excessive, might present as the 'small penis syndrome', an obsessive rumination with compulsive checking rituals, body dysmorphic disorder, or as part of a psychosis. However, it is often a worry that can be described as within the normal experience of many men. Various potential causal factors are considered. A thorough assessment, normalizing the worry and then exploring the treatment options in detail with the man, is essential to allow the matter to be consolidated satisfactorily within the male ego.

Elderly armpits can lift your spirits


Hormones detected by human smell can alter your mood

The armpit smells of old ladies are the latest mood-enhancing substances to be uncovered by scientists - but they warn that those of young men may have the reverse effect.
The Pennsylvania-based team believe that the effect may be due to the human ability to detect the presence or absence of hormones in sweat which signal aggression, reports "New Scientist" magazine.

Denise Chen, at the Monell Chemical Senses Center in Philadelphia recruited 30 volunteers in six different age categories - young girls and boys, young adult men and women, and men and women in their 70s.

Perfume and deodorant ban

The volunteers were banned from using perfumes or deodorants, or eating strong smelling food for four days, although they were allowed to take showers using unscented soap.

Throughout this period, a gauze pad strapped under the arm absorbed any odour they produced.

Then more than 300 university students sampled smells taken at random, filling in before and after questionnaires designed to test their mood.

People who had inhaled the samples taken from the armpits of old ladies responded significantly more positively.

Ms Chen said: "Old women had an uplifting effect".

But results showed the smell of young men had a noticeably "depressive effect", an outcome which might have been anticipated by any parent of a teenage boy.

In between these extremes, the smell of older people generally improved mood, as did the smell of females.

Hormonal signal

Jeannette Haviland, who also worked on the research, suggested that hormones in the body odour of the young might act as a signal of aggression.

She pointed to a recent study which showed that people can distinguish between the odours of both happy and frightened people.

Hormonal changes in old age, she said, were likely to make the odour of the elderly, particularly women, signal approachability.

A first case study of homosexual necrophilia in the Mallard Duck

The strange case of the homosexual necrophiliac duck pushed out the boundaries of knowledge in a rather improbable way when it was recorded by Dutch researcher Kees Moeliker.
It may have ruffled a few feathers, but it earned him the coveted Ig Nobel prize for biology awarded for improbable research, and next week he will be recounting his findings to UK audiences on the Ig Nobel tour.

Ducks behave pretty badly, it seems. It is not so much that up to one in 10 of mallard couples are homosexual - no one would raise an eyebrow in the liberal Netherlands - but they regularly indulge in "attempted rape flights" when they pursue other ducks with a view to forcible mating. "Rape is a normal reproductive strategy in mallards," explains Mr Moeliker.

As he recounts in his seminal paper, The first case of homosexual necrophilia in the mallard anas platyrhynchos, he was in his office in the Natuurmuseum Rotterdam, when he was alerted by a bang to the fact a bird had crashed into the glass facade of the building. "I went downstairs immediately to see if the window was damaged, and saw a drake mallard (anas platyrhynchos) lying motionless on its belly in the sand, two metres outside the facade. The unfortunate duck apparently had hit the building in full flight at a height of about three metres from the ground. Next to the obviously dead duck, another male mallard (in full adult plumage without any visible traces of moult) was present. He forcibly picked into the back, the base of the bill and mostly into the back of the head of the dead mallard for about two minutes, then mounted the corpse and started to copulate, with great force, almost continuously picking the side of the head.

"Rather startled, I watched this scene from close quarters behind the window until 19.10 hours during which time (75 minutes) I made some photographs and the mallard almost continuously copulated his dead congener. He dismounted only twice, stayed near the dead duck and picked the neck and the side of the head before mounting again. The first break (at 18.29 hours) lasted three minutes and the second break (at 18.45 hours) lasted less than a minute. At 19.12 hours, I disturbed this cruel scene. The necrophilic mallard only reluctantly left his 'mate': when I had approached him to about five metres, he did not fly away but simply walked off a few metres, weakly uttering a series of two-note 'raeb-raeb' calls (the 'conversation-call' of Lorentz 1953). I secured the dead duck and left the museum at 19.25 hours. The mallard was still present at the site, calling 'raeb-raeb' and apparently looking for his victim (who, by then, was in the freezer)."

Mr Moeliker suggests the pair were engaged in a rape flight attempt. "When one died the other one just went for it and didn't get any negative feedback - well, didn't get any feedback," he said.

His findings have provoked a lot of interest - especially in Britain for some reason - but no other recorded cases of duck necrophilia. However, Mr Moeliker was informed of an American case involving a squirrel and a dead partner, although in this case it is not known whether the necrophilia observed was homosexual or not as the victim had been run over by a truck shortly before the incident.

He dismounted only twice, stayed near the dead duck and picked the neck and the side of the head before mounting again. The first break (at 18.29 hours) lasted three minutes and the second break (at 18.45 hours) lasted less than a minute. At 19.12 hours, I disturbed this cruel scene. The necrophilic mallard only reluctantly left his 'mate': when I had approached him to about five metres, he did not fly away but simply walked off a few metres, weakly uttering a series of two-note 'raeb-raeb' calls (the 'conversation-call' of Lorentz 1953). I secured the dead duck and left the museum at 19.25 hours. The mallard was still present at the site, calling 'raeb-raeb' and apparently looking for his victim (who, by then, was in the freezer)."

Mr Moeliker suggests the pair were engaged in a rape flight attempt. "When one died the other one just went for it and didn't get any negative feedback - well, didn't get any feedback," he said.

His findings have provoked a lot of interest - especially in Britain for some reason - but no other recorded cases of duck necrophilia. However, Mr Moeliker was informed of an American case involving a squirrel and a dead partner, although in this case it is not known whether the necrophilia observed was homosexual or not as the victim had been run over by a truck shortly before the incident.
WOW that is absolutely off the wall... i laughed at the old person research study at first and then just sat amazed when i saw the next title on this one here!!!! damn thats off the wall, agian.

Measurement of breast volume: comparison of techniques.Palin WE Jr, von Fraunhofer JA, Smith DJ Jr.
A system of graduated disks has been previously described as a method to determine breast volume. The accuracy and limitations of this system have not previously been reported. Comparison of these disks with a standardized volumetric method shows this simple system to be accurate. Standard linear correlation analysis was good for the entire group of breasts measured (r = 0.718). Conversion to true volume M is represented by the least-square line M = 20.33 + 1.37G. The correlation is expected to fail at volumes greater than 425 cc (greater than the calibration on the largest Grossman disk). Elimination of volumes greater than 425 cc, however, produced no improvement in correlation coefficient. Firm breasts (i.e., capsular contractures) displace less uniformly into the conical restraint of the disk and cause an overestimation of their volume. Three breasts in this series were evaluated with Baker grade III and IV capsular contractures. Elimination of these values improved the correlation between the two volume analyses (r = 0.853 and M = 1.56G - 4.48). We suggest that when confronted with very large or firm breasts that volumes determined by the Grossman disk be interpreted with care. A formula for calculation of the true breast volume from the Grossman measurement has been derived and presented.

I mean, come on, who doesnt love the semen of rockhopper penguins?!!!!!!!!!!!


Semen collection and characterization in rockhopper penguins (Eudyptes chrysocome chrysocome).Waldoch J, Root T, Ramer J, Proudfoot J.
Indianapolis Zoo, Indiana 46222, USA.

Low egg fertility and hatchability is a common problem in captive populations of rockhopper penguins (Eudyptes chrysocome chrysocome). These conditions make sustaining a captive population challenging. A method for collecting and evaluating semen from rockhopper penguins was developed to assist in the evaluation of low egg fertility found in one captive population. Six adult male rockhopper penguins were conditioned to allow semen collection once a week from the start of breeding season until ejaculates no longer contained sperm. A total of 59 ejaculates was collected between 17 September and 31 December 2004. Forty-five of these samples were evaluated for volume, pH, sperm concentration, and sperm quality (motility, viability, and morphology). There was a large variation between individuals and between collections for each individual. The mean motility was 34.5% (+/- 22%). Mean volume of ejaculate was 0.23 ml (+/- .31 ml). Mean concentration was 16.9 x 10(6) sperm/ml (+/- 48.7 x 10(6) sperm/ml). Mean number of sperm per collection was 1.7 x 10(6) (+/- 4.2 x 10(6)). Mean percentage of living sperm was 82.9% (+/- 18.1%). Mean percentage of sperm with normal morphology was 82.1% (+/- 18.8%). Mean pH was 6.47 (+/- 0.49). During this season, only one of these males paired with a female. The pair produced one fertile egg, but the embryo died early in incubation. Male rockhopper penguins had low sperm concentration and low motility indicating that low male fertility may be contributing to the poor egg fertility rate. This work represents the first step in an ongoing study to improve captive breeding of rockhopper penguins.

It really boggles my mind that universities spend money on stuff like this....or that an IRB would approve it!!!

prld, Buff, and L'bane- you guys feel like co-authoring a study? I was thinking something like "Studies on the Interspecies Sexual Attraction of Emus to Human Beings" what do you think?!! Could make some big $$$$ if we win the Nobel Prize!!!

Scatophilic fantasies in prepuberty and Freud's stages of psycho-sexual development (author's transl)

[Article in German]

Amplification of the erotic enema deviance.
* Denko JD.

Use of enemas for sexual stimulation has been observed and named klismaphilia. Some klismaphiliacs indulge their taste for enemas in other wise normal sexual settings. Others combine it with fetishes, excretory and otherwise or with masturbation. Still others practice klismaphilia in homosexual or sadomasochistic settings or in group sex.

Klismaphilia--a physiological perspective.

* Agnew J.

Dr. Joanne Denko coined the work klismaphilia to describe the practices of some of her patients who enjoyed the use of enemas as a sexual stimulant. Since then questions occasionally appear in the professional literature asking about the relationship between enemas and sexual pleasure. This paper considers some of the physiological aspects of the human sexual apparatus that relate to anal sensitivity and explores why klismaphilia can be sexually grafifying. The paper starts with a discussion of the physiological basis for anal sensitivity and anal masturbation in both the human male and the human female. The paper then goes on to relate all this to the sexual sensations received from an enema, and discusses the similarities and differences between all these types of stimulation. Some of the psychological aspects of klismaphilia are also considered in relationship to the physiology involved. The paper concludes with a brief discussion of masked anal masturbation among the population at large. A comprehensive list of references from the literature is given to support these findings.
