This is a good question. While Ostarine shouldn't be generally used by women (see my post above about the "exceptions") men are a special case.
While impregnation by the man, Ostarine should be used actually or should be used more than three months ago. You will find also the statement in the studies (especially in the older one, in the newer ones only women where testsubjects (and yes, they are not "allowed" getting pregnant during the studies. I will paste here some quotes)), that men have to - at least for three months after the last Ostarine application - prevent during sexual activities.
Why?
As you know, fire and water or electricity and water doesn't fit well together. And a teratogenic substance combined with sperms (liked to a pregnancy) also doesn't fit that well. Sperm in men is going to refresh itself (by sexual activities or masturbation). The researchers selected a time period, in which 99.99% of all the possibly damaged sperm were renewed (talking in statistical language there is never a 100% possibility, nor a 0% by the way).
The feminine testsubjects had to fulfill following condition:
In another study about Ostarine, also men were accepted as testsubjects. The condition - to take part at the studies - were:
And as a reminder: for eight years now the studies about Ostarine were ongoig. And nothing changed concerning the Bicalutamide-story. If Ostarine as a Bicalutamide-derivative were not that dangerous, the conditions (for getting accepted as testsubject) must have changed.
But it has not.
As a personal advice: as a men, don't impregnate a woman while on Ostarine or less than 12 weeks after the cycle. There are other non-Bicalutamide-substances who don't act like the Bicalutamide (LGD-4033, RAD-140). The risk is still there, but a bit less dramatic than in women. Women have to prevent herselves 6 months after the Ostarine application, the researchers recommend.
Despite on these fact, I personally would wait for further studies, which cover the topic "pregnancy". Lower dosed LGD in this case would be IMHO the best option. It's not pure anabolic but also have some androgenic effect.
