Resveratrol is estrogenic at the estrogen receptor beta subtype, anti-estrogenic at the estrogen receptor alpha subtype. Just as compounds such as tamoxifen and clomiphene.

trans-Resveratrol was reported to have health benefits including
anticarcinogenic effects and protection against cardiovascular disease. One of the
mechanisms by which it exerts its action is through modulating the estrogen
response systems. Because estrogen is involved in male reproductive biology, we
investigated the effect of trans-resveratrol on testis and spermatogenesis.
Adult male rats were divided into 2 groups. The treated group was administered by
gavage 20 mg/(kg . d) of trans-resveratrol suspended in 10 g/L of
carboxymethylcellulose for 90 d, whereas the control group received only
carboxymethylcellulose during the same period. The relative weight of testes did not differ
between the groups. However, the diameter of the seminiferous tubules was
significantly reduced from 437.5 +/- 0.1 mum in the controls to 310.9 +/- 0.1
mum in the resveratrol-treated rats. This decrease was accompanied by a
significant increase in tubular density, from 3.20 +/- 0.18 in controls to 6.58 +/-
0.18 tubules/mm(2) in the treated group. Moreover, sperm counts were
significantly greater in the resveratrol-treated rats (24.8 +/- 3.30 x 10(7)) than
in the control group (14.1 +/- 0.80 x 10(7)), but sperm quality did not
differ. Serum concentrations of gonadotrophins and testosterone were significantly
higher in the resveratrol-treated group. We identified a novel activity of
trans-resveratrol. The daily oral administration of this phytochemical to adult
male rats enhanced sperm production by stimulating the
hypothalamic-pituitary-gonadal axis, without inducing adverse effects.
