Male pill: gene discovery may lead to contraceptive
It may be possible to develop a new male contraceptive pill after researchers in Edinburgh identified a gene critical for the production of healthy sperm.
Experiments in mice found that the gene, Katnal1, was vital for the final stages of making sperm; so a drug which interrupts Katnal1 could be a reversible contraceptive.
A fertility expert said there was "certainly a need" for such a drug. Contraception in men is largely down to condoms or a vasectomy.
The findings came our of infertility search by the researchers at the Centre for Reproductive Health at the University of Edinburgh.
