Male Infertility gene discovery

May 25, 2012

 

Scottish scientists have discovered a gene that plays a key role in production of healthy sperm, a breakthrough they say could soon pave the way for developing a new contraceptive pill for men.

At present, Contraception in men is mainly by condoms or a vasectomy. Therer is a pressing need to develop oral pill that is effective as well as reversible. Researchers at the Centre for Reproductive Health at the University of Edinburgh found a gene, called Katnal1, which was vital for the final stages of sperm production.

Katnal1 contains the blueprints for a protein which is important in cells that support sperm making. Without the protein, sperm do not fully form and the body disposes of them. The researchers, performed a trick of disabling the protein by controlling the gene Katnal1. Scientists hoped they would be able to perform a similar trick in humans to stop sperm developing, without causing lasting damage. If they can find a way to target this gene in the testes, they can potentially develop a non-hormonal contraceptive. The important thing is that the effects of such a drug would be reversible because Katnal1 only affects sperm cells in the later stages of development, so it would not hinder the early stages of sperm production and the overall ability to produce sperm.
