When it comes to taking charge of one's reproductive fate, women have had reliable birth control methods for decades now. For men the story is completely different. Though not for lack of trying, the medical establishment has failed to produce a consistently reliable method of contraception that is both non-permanent and healthy for men to take. But research coming out of Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center could change that via a simple gel applied directly to the skin.
Keeping wildlife baby-free is a hazardous business

In 1989, researchers at the University of California at Davis invented PZP, the first birth-control vaccine for animals other than humans. When injected, PZP causes a female’s immune system to block sperm from her eggs, offering a humane method of keeping populations in check. The compound worked in elephants, donkeys and deer, but it had a troubling side effect: the animals stayed in heat longer than normal. In one trial, deer were fertile for six months instead of one.
For women using birth control, that daily pill may soon be replaced by a simple addition to the regular moisturization routine. A new topical contraceptive gel that works in the same way as the pill has shown similar effectiveness when applied to the shoulders, arms, legs or abdomen daily -- and works without the side effects of sickness, weight gain, or a muted sense of sexual desire.
You aren't yourself anymore. It's a familiar complaint heard by women who have recently gone on birth control pills. Now studies are providing evidence for what many of those women, and the men who love them, have long known intuitively: the pill can alter the female brain, making a woman act like a different person.
Marijuana, ultrasound, and now mouse sex: the quest for a male birth control method has taken some weird turns.
The latest contender for the elusive male pill is an Israeli scientist who says he has developed a compound that temporarily inhibits the reproductive capacity of sperm, reports Israel21C.
The male birth control pill has lingered for years tantalizingly just out of reach, in the realm where rumor meets science. Recently developed hormonal and mechanical contraceptives never found an audience, serving only to highlight the absence of a male pill. Now, an examination of how smoking pot lowers fertility may make the male pill more than a persistent rumor.
Though the University of Utah in Salt Lake City might not be the first place one would expect to find researchers getting experimental in the bedroom, a team of scientists there have developed a new gel that can quickly shift from liquid to solid, for use in a vaginal condom that more easily protects against both pregnancy and sexually transmitted diseases.
When it comes to contraception, women have their pick of techniques. In addition to sperm-blocking barriers and foreign objects in the uterus (IUDs), there are about a million ways to pump extra hormones into the bloodstream (pill, patch, ring, shot, or implant).
For men, it's always been pretty much condoms or a vasectomy.
Scientists locate a gene that both regulates and blocks ovulation

Birth control may have revolutionized women’s lives, but it’s still a nuisance to take. The pill is 98 percent effective only if you (or your lady friend) takes it every day, at exactly the same time. Complete this task correctly, and the estrogen could give you nausea, headaches and moodiness. Thankfully, researchers at the University of Montreal and Louis Pasteur University may have found a more pleasant alternative.
