Feel free to lock topic if inappropriate but really opened my eyes to all sorts of interesting research.
Wikipedia extract:
'It has been suggested that fellatio may, through "immune modulation", play a beneficial role in preventing dangerous complications during pregnancy, especially reducing the risk of miscarriage and pre-eclampsia. Specifically, several research groups have reported pre-eclampsia, a life threatening complication that sometimes arises in pregnancy, is much less frequent in couples who practice oral sex, and even more rare in couples where fellatio regularly ended with a woman's swallowing her partner's semen.'
