why haven't they invented the male birth control pill?

Answer 1

Actually this has been tried. A form was instituted around the 1920's. Unfortunately, there was a side effect... sterilization. Here is something that has been shown to work.

If you want to have a decent protection against birth, do the following 2 things for one week prior to intercourse.

1. Wear briefs, not boxers.
2. Eat foods VERY high in black pepper.

It works. These are scientific facts, not home remedies.

Answer 2

The signals that are used (mimicked) in female birth control prevent the release of the egg from the ovary. However, the signal for the release of sperm from the epididymis are male orgasm, and are not part of a hormonal cycle, like that in women. While blocking spermatogenesis is a possibility in men, there are often negative consequences - these usually include the inability to reverse it (permanent sterility) and/or other hormonal side effects in men.

However, that still hasn't stopped research into the problem. Research continues, and it seems that major breakthroughs are on the horizon. For more details, see:

Answer 3

Greetings;

Actually the problem lies in numbers. Female birth control pills work by preventing ovulation, an event that occurs once a month and normally results in the release of one egg. For a male contraceptive to function the drug needs to halt spermatogenesis, an event that is occuring continuously. In order for a male contraceptive to be effective it would have to reduce spermatogenesis by at least 99.6% in order to have the same effectiveness as the birth control pill. This is challenging to say the least. Shutting off spermatogenesis is actually quite easy. Shutting it off without horrible side effects (and being able to restore fertility) is hard.

Answer 4

Because the male reproductive system is so simple that, of the stuff that they've tried so far, anything that prevents conception also prevents intercourse (either from causing impotence or inducing lack of desire).

The female reproductive tract is such a complex piece of engineering that even a tiny glitch in the system means no baby, but most of those glitches have no effect on a woman's sex drive or sexual responsiveness.

So while it's a popular theory to attribute the lack of a male pill to sexism, it's really matter of engineering.

Answer 5

Cause men invented the female birth control pill first and beat you to the punch

Answer 6

The latest research isn't focused on stopping the production of sperm, but on blocking the processes that the sperm employs to fertilize an egg. It's a rather complex process, so in theory it shouldn't be hard to stop since even shutting down one step in the process would result in an infertile male. Unfortunately, real life rarely adheres to human theory as we'd hope. Still, give it a few years, and I'll bet such a pill will be produced.

Answer 7

They are trying to. The main hormone is Testosterone right? You don't wanna cut that off from a man...You'd only have a bunch of females on the planet.

Answer 8

I think that to control conception through the male, you would have to apply something that reduced his testosterone production.

If you did that, he would not get sexy, would not get an erection, so that would defeat the object of being able to have sex without impregnating.

Answer 9

another reason is that since guys can't get prgenant they personally don't want the responsibility of taking a birth control pill

Answer 10

I like it better that women control reproductive choice.
