Broadly speaking, our society has put the burden of contraception on the ladies. From the pill and the new patch, to the coil, the diaphragm, the female condom, the sponge, foam, the morning after pill and various creams, suppositories and jellies, women have been offered countless ways to prevent birth. Men, well, we’ve had…the condom. But with the male contraceptive injection testing at almost 99% effective, women may well be asking the guys to shoulder more responsibility.

Last month, it was announced that testing of the male contraceptive injection (MCI for the remainder of this article) produced very positive results. Of the 1,045 men tested in China, only one in every 100 men fathered a child while taking the new injection. This, from Canadian station CTA:

Chinese researchers injected 1,045 healthy Chinese men aged 20 to 45 years with a 500 mg of testosterone undecanoate in oil, once a month for 24 months. All of the study participants had had at least one child and all their female partners, aged 18 and 38 years, also had normal reproductive function.

They found the contraceptive was almost 99 per cent effective, with a failure rate of only 1.1 per 100 men.

The MCI works by using a form of testosterone to temporarily stop sperm production (which is ironic, as most of us know testosterone as a hormone that causes sperm production). There were no side effects for this new version of the MCI; in previous incarnations, test subjects had suffered mood swings and lower sex drives.

And, just like the female contraceptive pill, the effects are reversible. It took an average of around six months for reproductive functions and sperm production to return to normal.

Such positive results may lead to the drug coming to the market in five years or less. But here’s the big question ladies – will you ask your guy to take it? Or, guys, will you volunteer?

Men have always been wary of anything messing with their most private of privates, and a simple procedure like a vasectomy has most men breaking out into a cold sweat (myself included, I’m afraid to say).

I, for one, am wary about the MCI, but I’m open to try it. For one thing, the burden has always been placed on my wife. Over the years, I have had to witness her trying several forms of birth control, all with various (and often uncomfortable) side effects. She’s done her part, and now it’s clearly (and rightly) my turn.

So how about it? Will you, or won’t you?
