S-23 is a SARM examined preclinically for androgenic effects and male hormonal contraception. Rat findings do not establish a human contraceptive or muscle-building treatment.
What did the study investigate?
Male-rat experiments examined sperm production and recovery in a hormonal contraception setting. Parts of the experimental design also involved another hormone. Reference: S-23 preclinical male contraception research
Why interpret recovery carefully?
Reversal of effects in an animal experiment cannot define a human recovery timeline. Species, baseline physiology and study design differ.
What matters when planning a family?
Disclose the names and timing of previous substance exposure during assessment. The word reversible alone is insufficient evidence for a fertility decision.
US FDA warns that SARMs are unapproved drugs and may cause serious health problems. FDA: SARMs
Frequently asked questions
Can S-23 be used as self-directed contraception?
The cited animal research does not support that use in humans.
Does animal recovery guarantee human hormone recovery?
No. Human outcomes require appropriate human evidence.
