London: Much research is underway to find a safe and effective male contraceptive pill. Though it was speculated that a male contraceptive pill is just around the corner but now people will have to wait more. Researchers have found that hormonal male contraception via testosterone does not stop the production of healthy sperm.
Based on the study involving mice it was found out that a previously developed male hormonal oral contraceptive method (via testosterone) is unable to stop the production and/or the release of sperm.
Ilpo Huhtaniemi from the Imperial College of London in Britain said that, “Our research explains why the efficacy of male hormonal contraception is not as effective as expected and it provides clues on how to improve the method”.
Scientists demonstrated that the male contraception approach by testosterone has an inherent problem - spermatogenesis - where production of sperm from the primordial germ cells does not stop.
They found that administering increasing doses of testosterone to infertile mutant mice did allow sexual function to return at a certain dosing threshold which was expected.
What was not expected, however, is that spermatogenesis also returned at that dose. This suggests that it is impossible to give a single dose of testosterone that allows for sexual function and the suppression of pituitary gonadotropin secretion, but also does not initiate sperm production.
