- QUESTION: Several years ago I read that a birth control pill for men would be
- available in the near future. Well the near future is here but where's the
- pill? I think it's time for men to be as responsible for birth control as
- women are. Can you tell me what has happened in this field of research, and
- when we can expect to see the new product? Thank you.

- ANSWER: While there still may be a birth control pill for men available in
- the future, it may be further down the line than you were lead to believe,
- maybe as long as 10 to 20 years. Don't blame the scientists, the male biology
- is quite different from that of women and that distinction is the basis for
- the difficulty. All that is necessary in a woman's biology to prevent a
- pregnancy is to prevent the release of one egg per month. In a man it
- requires interfering with the production of sperm, something that occurs on a
- continuous basis in men from puberty until death.
- At present research is centered on the male hormone testosterone. This
- male hormone must be present in order for the production of sperm to take
- place. However scientists can inject a synthetic testosterone into the man,
- which the body interprets as real, and so shuts down the production of the
- real hormone, and that effectively stops sperm production. But that takes an
- injection each week.
- Another mechanism is also being explored. For testosterone to be
- produced, the brain secretes a stimulating hormone called gonadotropin
- releasing hormone (or GNRH for short). That in turn sets off the production
- of the male hormones required for sperm production. Using a chemical with a
- similar formula (called an analogue), the secretion of testosterone can be
- stopped. And with the end of sperm production goes male fertility and
- unfortunately his sexual desires as well. And that process requires a daily
- injection to be effective. The long range effects of both these methods have
- yet to be fully determined, although fertility returns once the regular
- injections are discontinued. It seems that for the foreseeable future,
- responsible men will have to rely on condoms, or surgery (vasectomy) if they
- want to undertake the responsibility for controlling the onset of pregnancy.
- Besides these injections have not been approved for general use, and are still
- merely experimental.
