Hormonal contraception may become a safe, effective, and reversible form of birth control for men, according to a new study. The study revealed that the combination of testosterone and progestin suppressed sperm production faster and more completely than testosterone alone. "It is possible to suppress sperm output to concentrations that are comparable with reliable contraception in most, but not all men," said the lead author of the study. "The rate of suppression is comparable to that achieved after a vasectomy."

Women who have tried to conceive using in vitro fertilization (IVF) methods are painfully aware that timing is of the essence. There are cancelled vacations, too many sick days taken from work, and the necessity to plan everything around "the treatment." In a surprising finding, researchers have discovered that the same pill used to prevent pregnancy can actually help a woman conceive.
