Male Contraceptive Success DownUnder

Male Contraceptive Success in Australia
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.

Yeah, because SO MANY men are just dyign to get girls pregnant and pay child support.

[look_ma]

[Cantacuzene]

YOu still ejaculate semen I'm guessing, just no boys swimming in it.

Yeah. I thought I remembered hearing that one of the side effects was that the men never fully recovered their sperm count. Might be a different study though. :shrug:

no, not that the guys are lying because they want to get the girls pregnant, they would lie because they wanted sex, w/o a condom. i know more girls who got pregnant because their partner refused to use a condom then girls who had kids because they sneakily lied about being on the pill. so why wouldn't it follow that the guys who are lead by their dick would lie about having this birth control, just another way of getting the girl into bed w/o a condom?

kudos to the guys who consider the possibility of child support and pregnancy when they get into bed with a girl, but i think they're in the minority!

I think your female friends are dumb for sleeping with such low class guys. It doesn't speak well for them to make such poor life choices.

*sigh* you might be "high class", but most guys tend to think with their dick first, head later. you're very fond of pointing out how you're better then people, so in this case, maybe it's true - you think about your consequences before you have sex with someone, but a good chunk of your fellow males do not. yeah, it was a bad life choice, but it was a bad choice for both partners involved. and most people have made a bad choice at one point in another, it's just the way of life.

you apparently missed the point... i suspect that guys will use their new found birth control as a way to lie their way into a girl's pants just as much as a girl would lie to trick her way into a committment.

btw...according to your logic, you hang out with some rather low class women (and dumb guys) that want to trap a guy into a relationship by getting pregnant. ;)

[Airencracken]

Experience??? :D But I would agree. Or at least I think I would. I'm sure it would be interesting for a while.

I never referred to a personal experience that I or my friends have had, whereas you did, so the turnbing around of the logic doesn't work that way.
