After unilateral testicular removal in adult males, if the testicle on the other side of the same progression functions normally, erectile function is usually not affected. If the testes are removed bilaterally, erections are usually no longer possible due to insufficient androgen production. The main function of the testes is to produce androgens and spermatozoa. Androgens maintain male secondary sexual characteristics, male desire and erectile function. If one testicle is removed, erectile function is usually not affected if the other testicle produces normal hormones. If both testes are removed, erectile dysfunction can occur due to insufficient androgen production. If you need to undergo orchiectomy, please consult a regular hospital for a clear diagnosis before choosing a treatment plan.
