Human fertility gene found

Researchers have for the first time identified a gene that boosts fertility in humans. A single amino acid substitution in a gene linked with cystic fibrosis may be responsible for the differential reproductive success of some men living in a religious community in the US prairies, according to data presented yesterday (Apr. 2) at the linkurl:Sackler Colloquium on Evolution in Health and Medicine;http://www.nasonline.org/site/PageServer?pagename=Sackler_Evolution_Health_Medicine in Washington, D

Many genes have been identified that cause infertility in humans, but finding genes that enhance fertility is tougher because people often choose to limit their family size for various cultural, social, and economic reasons. The linkurl:Hutterites,;http://www.hutterites.org/ however, do the opposite. This isolated group of Anabaptists living in the great plains of North America eschews birth control. Families often have more than 10 children, and they generally wait less than two years between successive births. Hutterites also rarely marry outside the community...
