Testosterone's Role in Male Fertility

Administering testosterone can function as a form of male birth control by halting the body's natural production of the hormone. This injection leads to a cessation of signals sent to the testicles, resulting in a significant decline in sperm production, potentially down to zero. Historically, this hormonal treatment was infrequently associated with infertility issues, with only a few cases reported annually. However, as awareness and usage have risen over the past two decades, the link between testosterone therapy and male infertility has become increasingly recognized among reproductive and infertility specialists.
