For men "the pill" is still far away as hormonal male contraception via testosterone is unable to stop the production and/or the release of sperm due to specific problems with optimal dosing.
Ilpo Huhtaniemi, Ph.D, and a researcher involved in the work from the Institute of Reproductive and Developmental Biology at the Imperial College of London said that their research in mice explained why the efficiency of male hormonal contraception was not as effective as expected and it provided the clues on how to improve the method.
Scientists found that administering increasing doses of testosterone to infertile mutant mice did allow sexual function to return at a certain dosing threshold.
Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal said that since the pill was developed, they had been aiming for an equivalent for men and this report suggested that they may be finally reaching the end of administering testosterone for this purpose.
The study was published in the FASEB Journal.
