Women who regularly give their boyfriend or husband oral sex and swallow their sperm may be less likely to suffer recurrent miscarriages, scientists have claimed.
Researchers believe ingesting semen strengthens a pregnant woman’s immune system and could help foetuses grow healthily.
Semen contains hormones and proteins from a man’s body which some women may need to become accustomed to having in their body.
Unprotected sex is one way to for women to get their bodies used to their partner’s sexual emissions, but it’s believed semen may actually be better absorbed in the digestive system.
Ora Researchers from Leiden University Medical Centre in the Netherlands tested their theory by comparing the pregnancy history and oral sex habits of 234 women. However, before men get too excited it’s worth noting that the study was small and did not provide 100% concrete evidence that swallowing sperm was leading to the lower miscarriage rate.
But they believe their results are strong enough to suggest a link between the two and called for more research. Some 97 of the women had suffered from recurrent miscarriage – the name for a condition in which a woman has three or more miscarriages in a row.
The condition is thought to affect around one in 100 women in the UK and may be triggered by genetic or hormonal problems, or infection. Many cases are unexplained. In their study, the scientists found the women who experienced regular miscarriages were less likely to give their partners blowjobs.
‘Oral exposure to seminal fluid seems to… influence pregnancy outcome in a positive way,’ the researchers wrote.
They added: ‘Our results suggest an association between less oral sex and the occurrence of recurrent miscarriage.’
By building up the mother’s tolerance to substances from the man’s body, the parents could give a foetus a better chance of thriving.
This could make the mother’s immune system less likely to reject the baby and lead to its death, the researchers believe.
The study was published in the Journal of Reproductive Immunology.
