A new study published in the Journal of Sexual Medicine has found a link between homosexuality and female fertility.
The ''gay gene'' has cruised back on to the scene. Homosexuality tends to run in families, according to Dean Hamer, the American scientist who has made a study of the genetic basis of human sexual preferences. His latest research, apparently confirming a genetic component to homosexuality, has once again rekindled controversy into the genetics of the more sensitive aspects of human behaviour.
