Birth control pill for men could be available soon, says WHO
Women have been awaiting it for years, and, according to researchers, it looks like the pill for men is finally in sight. The other good news is that is doesn't seem to have any side-effects.
The World Health Organization (WHO) is currently testing a hormonal birth control pill for men. Michael Zitzman, who is heading the study, told Deutsche Welle that it will likely be available to the public in 2012 at the earliest.
Deutsche Welle: Mr. Zitzman, would you take the pill for men yourself?
Prof. Michael Zitzman: Yes, of course.
Why is everyone making such a big deal about this pill for men when it isn't even a pill?
It's kind of like a product name, because the pill for women is so well known. There's never been an oral pill for men that can bring the same result as it does for women. Men have had to use shots, implants, and gels that are applied on the skin.

So how does the pill for men actually work?
With this hormonal form of contraception for men, natural testosterone is applied together with gestagen, which is a precursor of testosterone. The goal is to completely suppress the hormones that stimulate the production of sperm in the testicles.
How much testosterone and gestagen is needed?
The patient takes the dose that used for men who've had a testicular disease, for example, and need to take replacement hormones. They have to take extra testosterone to avoid side-effects like depression, osteoporoses or anaemia.
Is there a recommended dose?
1,000 Milligrams. That's about 1 gram of testosterone every two months.
You've said that sperm production is reduced by up to 100 percent. But that's not irreversible, is it?
No, of course not. If that were the case then you might as well just have a vasectomy. This method is completely reversible - that's been the case with all the men tested. It takes about four months, or sometimes only two, for the sperm to build up again.
It takes the same amount of time for the sperm to disappear, since they go through a maturing process in the testicles. Once this process has begun, then their independent of the hormones. That means that the sperm continue to develop without any hormones. In the study, we noticed that after 4 weeks the sperm had disappeared in some of the men. It usually takes two to four months, however.
The pill will not affect appearance, say researchers
Does the additional testosterone change the man's body in any way? Testosterone is usually associated with muscles, body builders, and doping.
It depends on dose of the hormone. When a healthy man is given the same dose of testosterone that he would normally produce, then his body automatically reduces its own production of the hormone and the sperm count drops. That means that his hormone levels don't change and neither do his appearance or health.
How far along is this study?
The idea of a birth control pill for men has been around for a while now, and there have been lots of research projects…
It has been around for a while. The first thing we had to do was to figure out how everything works. How well does it work and what are the side effects? The side effects that had been reported came from studies where placebos were used, which means some of the men received fake medication.
The side-effects all resulted from Placebo-Niveau. Some of the men felt poorly or had trouble sleeping, but that probably had nothing to do with the actual medication. It might have just been a side-effect of knowing they were taking part in a study, or it could also have just been a coincidence.
So there are no side effects?
The only side-effect is that the testicles shrink a bit, because they stop working. However, they return to their normal size when the men stop taking the pill.
Researchers don't know if the pill for men appeals to couples
When can we expect to see the birth control pill for men on the market?
That depends on how the pharmaceutical industry sees it and whether the World Health Organization receives a license. I think that the study by the World Health Organization will be successful since we already know from past studies that it works.
What we still need to find out is what couples think of this method. Do they feel good about it? I can't answer that just yet, because we still need to find the answer to that. We think that, if everything
well, the pill could be on the market as early as 2012 or 2013.
Is the pharmaceutical industry interested?
Yes, because the substances that are needed for the pill are already on the market. They've been permitted for other uses and the authorities would just have to approve them for the pill for men. Then the industry could put it on the market relatively quickly.

Do you really think the men would take it? I doubt...
