Key proteins identified in the quest for male contraceptive

In an advance toward a long-sought new male contraceptive, researchers in China have identified key proteins in men that suppress production of sperm and could become new targets for a future male birth control pill. Their study is scheduled for the October 3 issue of ACS' monthly Journal of Proteome Research.
Jiahao Sha and colleagues point out that scientists do not understand one effect of the male sex hormone, testosterone how injections of the hormone suppress production of sperm. Building on a previous study showing almost total sperm suppression with an injectable testosterone combined with a synthetic hormone called levonorgestrel (LNG), the researchers sought new insights into how hormones affect sperm-producing cells in the testicles.
In a new study on men, they found that testosterone combined
