Testosterona pode causar impotência sexual?

In this informal educational video, the speaker explains how exogenous testosterone suppresses the hypothalamic‑pituitary‑gonadal (HPG) axis via negative feedback, leading to reduced luteinizing hormone (LH) release and consequently halting testicular testosterone and sperm production. Prolonged suppression can cause testicular atrophy, potentially resulting in permanent sexual impotence and infertility. The speaker emphasizes that higher doses and longer durations of testosterone use lengthen the recovery time, sometimes preventing the testes from ever regaining function. He critiques the common belief that stopping testosterone or using post‑cycle therapy (PCT) will quickly restore the axis, noting that recovery is not guaranteed and can take years, as illustrated by an anecdote of a former student who required two years to achieve fertility after long‑term use. The overall message is a cautionary warning against unnecessary testosterone supplementation, especially for individuals desiring future fertility.
