Mesterolone is a synthetic androgen associated with the name Proviron. Fertility research exists, but this does not establish reliable pregnancy or hormone-recovery benefits for everyone.
What did the fertility trial find?
A multicentre WHO trial published in 1989 compared mesterolone with placebo. Semen outcomes did not show a clear advantage; pregnancy estimates had wide confidence intervals. Small numerical differences should not be presented as guaranteed benefit. Reference: WHO mesterolone fertility trial (1989)
Why separate the intended outcome?
Fertility, symptoms attributed to low testosterone and physique are different questions. A pregnancy study cannot establish muscle-building efficacy, and improved symptoms do not establish improved semen quality.
What information helps a consultation?
Record symptoms, timing, fertility plans and previous medicines or substances. Interpret testosterone, LH and FSH in context instead of selecting a hormone-recovery approach from a drug name alone.
Frequently asked questions
Does Proviron guarantee improved fertility?
No. The cited research does not establish that promise.
Can normal hormone results replace a fertility assessment?
No. Hormone measurements and reproductive outcomes provide different information.
