Male birth control

Wasn't one study conducted by the World Health Organisation? Are there any links to the published results?

Male Contraceptive Success in Australia Sun October 5, 2003 07:02 AM ET SYDNEY (Reuters) - Australian researchers said on Sunday they had conducted a successful experiment using two hormones to suppress sperm production, which they said could lead to the first injectable male contraceptive. Men in the trial of 55 couples received hormone treatment over the course of a year using a combination of the male hormone testosterone and progestin, which is used in female contraceptive pills. Scientists from Sydney's ANZAC Research Institute and the Prince Henry Institute of Medical Research in Melbourne said the aim of the trial had been to "switch off" male sperm production. None of the men's partners became pregnant during the trial and none showed any side effects. The hormone treatment was the only form of contraception used during the trial, they said. "This is the first time a reversible male contraceptive that will suppress sperm production reliably and reversibly has been fully tested by couples," the institute's principal investigator professor David Handelsman said in a statement. He said a testosterone implant had been injected every four months and a progestin had been injected every three months. "This shows the way for a final product to be a single injection containing testosterone and a progestin which will easily be given by local doctors on a three-four monthly basis and still maintain male sexual health," Handelsman said. Developing an effective and convenient male contraceptive has been difficult, in part because of the rapid rate at which men produce sperm. A recent British trial showed promise but side effects stopped the trial. Testosterone is often linked with virility but treatment with the hormone can suppress the production of sperm by reducing levels of hormones called gonadotropins. Too much testosterone can have harmful effects, such as reducing levels of the "good" cholesterol HDL. Experimental male contraceptives often include another hormone, such as a type used in female contraceptives, to block side effects.

I think I might try it when I eventually go on HRT and don't have to worry about coming off after the deca.

dont count on it - many bros have got there chicks preggo while mid cycle or even while on for ages.

This should take a few years but they can't keep the cat in the bag forever. And NO birth control is 100% effective anyways, I just find it very liberating for men. Womens "needs" have been catered to for years now, its about time they recognized some good things for US. The only times in my life I ever sport-fucked was during a heavy cycle...simply to calm my fears of knocking up some dame I dont want long term. This shit is gunna sell like hotcakes once the FDA approves it, and they WILL approve it because this could cause a GOLD MINE for the pharmacuetical companies. They can't ignore significant data forever. Forgive me guys because I should know this, but can some one refresh me on what a "progestin" is? FOX

oh - there is a big difference between a progestin like deca and progesterone. Deca has slight activity but this is nowhere like popping a progesterone pill. No amount of deca would equate I think. Prog is a womans hormone - I dont like the sound of that.

progestin is a female sex steroid it is slightly androgenic and can cause acne in woman is imbalanced. It is not a muslce builder though. It is similar in structure to estrogen but slightly different - like test is different to nandrolone or winny. It is present naturally in the body (at least in woman!?)
