While female sexuality appears to be more fluid, research suggests that male gayness is an inborn, unalterable, strongly genetically influenced trait. But considering that the trait discourages the type of sex that leads to procreation — that is, sex with women — and would therefore seem to thwart its own chances of being genetically passed on to the next generation, why are there gay men at all? This longstanding question is finally being answered by new and ongoing research. For several years, studies led by Andrea Camperio Ciani at the University of Padova in Italy and others have found that mothers and maternal aunts of gay men tend to have significantly more offspring than the maternal relatives of straight men. The results show strong support for the "balancing selection hypothesis," which is fast becoming the accepted theory of the genetic basis of male homosexuality.

Gay and bisexual men in NI, who have been in a relationship for more than three months, may soon be able to donate blood.

Further changes are expected to come into effect in the summer of , the Department of Health has announced. Robin Swann added: "I am pleased to be able to introduce this change to donor deferral policy in Northern Ireland, which means MSM in longer-term partnerships will no longer be automatically deferred from donating blood, provided they have been with the same partner for the previous three months and meet the revised medical criteria. As with the decision to reduce the blood deferral rules earlier in the year, he said he had been advised by a Safety of Blood, Tissues and Organs SaBTO committee, which advises UK health departments, and was "content" with the decision.
