Semen withdrawal?

I've never heard of a condom being used for that. :D Don't see why a woman even would, as opposed to you gentlemen.
 
NEVER have nasal sex without a condom, or you run the risk of contracting snyphilis.

(sorry, couldn't resist)

Oh come on - Wikipedia?! - where are the bullet points about prostaglandins being an alternative to nerves and telling the uterus to have an orgasm. On what do you base your statement that prostaglandins from the male ejaculate have a physiological effect on the female?

I remember a similar story of uterus contraction and increased cervical permeability from human physiology classes and I believe it was studied by M. Bygdeman et al. in the 60’s.
Acta Physiol Scand. 1963;59:43-51. http://www.ncbi.nlm.nih.gov/entrez/..._uids=14065853&query_hl=3&itool=pubmed_DocSum

I think that’s where the name prostaglandins came from. It’s effects were later confirmed in animals and worried obstetricians about the effects of sex during pregnancy. It later turned out that the intravenous administration of prostaglandins or high concentrations gave cramps and pain but normal volumes and concentrations didn’t and were quite safe for Intra Uterine Insemination.

Based on the effect of prostaglandins, a medical hypothesis was published that prostaglandins in semen could influence the woman psychologically. I think that’s what the author is referring to, but it has had little or no follow up after 1986. Despite the physiological effect which is clear, an effect that might be psychological is harder to prove and harder to interpret (as with most things in psychology and psychiatry), but who knows…
Med Hypotheses. 1986;20(2):221-31 http://www.ncbi.nlm.nih.gov/entrez/...t_uids=3637620&query_hl=3&itool=pubmed_DocSum

By the way, oral administration seems to have an effect too… in men :D
Fertil Steril. 1988;50(5):789-94 http://www.ncbi.nlm.nih.gov/entrez/...t_uids=3181489&query_hl=3&itool=pubmed_DocSum

I also think there are a lot of confounding factors, most women and all men seem to think so…
Too many jokes, so I won't start naming them...

Brilliant, thanks for that. Prostaglandins are marvellous molecules capable of all sorts of wonderful effects & it's not surprising that there is some measurable effect in the female after intercourse due to prostaglandin in semen.

Sounds like a combination of Chinese whispers and male wish-fulfilment has taken us from the actual eveidence to casebro's bizarre assertions. Or maybe s/he just met a drunk, oversexed endocrinologist in a bar at a "Dodgiest chat-up lines of the decade" conference.

By the way I was relieved to read it was the prostaglandin that was administered orally to the men in your last reference, not the... the... euuuuugh.

And you're right about the jokes.
