Pill by University of Washington

Dr. John Amory with the University of Washington works on male contraceptive research.

SEATTLE - The University of Washington Medical Center is working on a birth control breakthrough -- a contraceptive pill for men.

Dr. John Amory is looking for a few good men to help him create a birth control pill for guys. Test subjects don't get to have sex for trials; it's their sperm that's tested.

Guys don't have a lot of options when it comes to contraception: condoms, vasectomies, or their partner.

"Women do carry the undue burden or unfair share of current contraceptives," Amory said.

For 30 years, UW researchers have worked to create a male pill and they think they're about five years away.

The test subjects put testosterone in their body with the goal of suppressing sperm, but it's a difficult task because men produce 1,000 sperm every second. Whereas with women, there's just one egg a month to control.

Side effects for now include changes in muscle mass, mood, and libido, but the idea is drawing support from women. Still, there's the matter of trust -- would men remember to take a pill every day?

"The studies show women don't trust man to take a pill but women in committed relations would trust their partner to take a contraceptive on a regular basis," said Dr. Mara Roth.

Currently, female contraceptives account for two thirds of the current contraception in United States, and some men say that could change if they had more options than abstinence, a sheath, or a snip.

Healthy men between 18 and 50 can enter the intensive study and receive $1,300 if they complete it. For more information call (206) 616-1818.

Injection by Edinburgh University Men wanted to test contraceptive

Men will need an injection in their bottom every two months Scientists are seeking couples to take part in a trial of a new contraceptive injection for men. A team from Edinburgh University is involved in the World Health Organisation research into the jab. The scientists claim it can give much better protection against pregnancy than condoms. And it is hoped the work could help pave the way for such a form of contraception to become more widely available. Researchers at the University of Edinburgh are hoping to recruit 20 couples from the south east of Scotland to take part in the study - which is being run by the World Health Organisation. Fully reversible The injections contain the hormones testosterone and progesterone, and are given to the men every two months. Sperm counts fall rapidly, and when these are low enough couples taking part in the trial would use the jabs as their method of contraception for a year. Scientists also stress that the effects of the injections are fully reversible. Professor Richard Anderson of Edinburgh University's reproductive and development sciences division said: "If this trial is successful I imagine there would be interest in looking at marketing the injection as a male contraceptive. 400 couples "Even if not all men would be keen on an injection, there would definitely be a market to make such a treatment available." The study will involve 400 couples from 10 centres across Europe, Asia, South America and Australia. And Professor Anderson said: "This larger study is needed to add to the evidence as to how good these longer acting injections are and what couples think about it." The study is looking to recruit couples where the man is aged under 45 and the woman is under the age of 37. Those interested in taking part can email j.george@hrsu.mrc.ac.uk.
