I was looking for info on natural birth induction methods last night and I came across this tasty tidbit:
Oral Application of Semen
About fellatio: Actually, it would probably be beneficial, if the idea is to get the labour started. A great OB in Hamilton (John Lamont, I believe) spoke to our class about sexuality and pregnancy. He mentioned the concept that prostaglandins are absorbed 10X more efficiently through the gut than through the vaginal mucosa, with respect to semen and labour onset.
Blowjobs: Is there anything they can’t do?
