Male Contraceptive in the Form of Injections

This study is a vast improvement over others due to reliability and side effects. Past attempts have had undesirable side effects such as mood swings and lowered sex drive.

Hm, that funny. Those side effects are common for some women who use these drugs, but we need to shield men from it? Male scientists can't let men experience these side effects because then they'd have nothing to complain about women for!

Joking aside, I think this is a great idea - but then again, I am a woman. I do think that if men had to take a monthly hormone, they'd be a lot more understanding about some things. But, the tone of the articles on this topic seem to suggest that men are asking for this - are they? Are you other readers? I do think it's quite interesting and look forward to see what others have to say.

"The long-term safety of this hormonal male contraceptive regimen requires more extensive testing with a focus on cardiovascular, prostate and behavioral safety."

According to this study from Johns Hopkins and the National Institute of Aging, men over 50 years of age with high blood levels of testosterone have an increased risk of prostate cancer. Hopefully, researchers will test other age groups as well for safety's sake. The fact that some men with prostate cancer are now given testosterone-suppressing drugs makes me skeptical of the safety of such a male contraceptive.

As for the "behavioral" aspect, check out this article in Scientific American. Testosterone alone may not cause violence, but you might want to watch "Fight Club" again.

Thanks for the links. Prostate cancer is the second highest killer of men, right after heart disease. I would welcome contraceptive shots as a way to eliminate the need for condoms, since I left my promiscuity, and those who are still promiscuous behind many years ago. Condoms put a crimp in my 'style', much like putting socks on a chicken. At my age I need all the help I can get!

As has been stated in 'The New York Times' in an article on the relationship between masturbation and prostate health, that frequent ejaculation was decidedly healthy for the prostate gland, and possibly reduced the incidence of cancer. The study also blew holes in the idea that it was detrimental to athletic performance.

So a hint to you women; Keep your man healthy, it's more fun that way.

I'd a totally held my sons down and given them these!

I'd a taken them at their age.

I can see the contraceptive advantage of the image of a syringe on a teenager. Especially knowing where it would be applied!

I am impressed with this concept for men and I know a lot of women that would love to see their partners having this treatment, when you think about it its a good payback for all the little pricks they have had to suffer.

Nice comment.

My father-in-law always told me of a male contriceptive pill. It was huge and no one could swallow it.

They said that was not the point - you put it in your shoe and it made you limp!!
