Interesting article about a very serious condition, that I am posting because I know you pervs will delight in the other aspects of it:
Danish medical researchers find oral and condom-free sex reduces the risk of preeclampsia.
New research from Roskilde Hospital in Denmark shows that male sperm contains a special protein that seems to prevent pregnancy induced hypertension (PIH), and suggest that condom-free and oral sex can be beneficial in avoiding PIH.
Roskilde Hospital Consultant Physician Thomas Hviid and Ph.D. student Snezana Djurisic have investigated why some women seem to have a higher risk of PIH – which is also known as preeclampsia or toxaemia – than others.
“Other studies have shown that the shorter the period that a couple have known each other and had sexual relations before a pregnancy, the higher the risk of PIH. First time pregnancies are also more liable to suffer PIH, and their illness is worse than women who have been pregnant previously,” says Dr. Hviid.
“Finally there are studies that show that couples who have used condoms or a diaphragm prior to pregnancy have a higher risk,” he adds.
The research seems to point to a reverse correlation between male sperm and PIH, which affects 3-5 per cent of pregnancies. Most cases can be treated, but in the most serious cases, the mother has cramps or have a stroke.
“It is a life-threatening condition and can come out of the blue – in fact also in the hours and days immediately after delivery,” Hviid says.
Hviid’s research has built on the hypothesis that PIH is a type of female immune reaction to an embryo, which is partly a foreign organism.
“Pregnancy is a sort of natural transplantation. And just as you give medicine in organ transplants to dampen immune defences, nature has also constructed some natural substances to make sure that a woman’s immune system doesn’t go haywire,” Hviid says.
The protein that Hviid has found in male sperm is Histocompatibility antigen, class I, G (HLA-G), which is also found in the placenta and fluids that surround unfertilised ova.
Hviid’s hypothesis is that more sex, during which sperm enters the body either through oral or non-condom sex, provides more HLA-G, which can impact on the immune system and slowly prepare it for fertilisation and pregnancy.
“Well it’s certainly harmless advice in the cold season,” says Hviid.
National University Hospital Fertility Consultant Ole Bjarne Christensen says the results of the research are very interesting. PIH is a serious condition that also affects many women in developing countries and young teenage mothers who become pregnant by mistake, the first time they have sex.
“In theory you could produce pure HLA-G and give it as an injection – a sort of vaccine against PIH,” Christiansen says. “Perhaps not to all women, but to those at risk. It has to be tested, but it sounds promising,” he adds.
