Swallowing your partner's sperm regularly can protect against miscarriage, researchers claim
- Researchers from the Netherlands compared the oral sex habits of women
- Sufferers from recurrent miscarriage perform less often, less often, they found
- The scientists suggest that swallowing sperm can boost maternal immunity
Women who regularly give their male partner oral sex are less likely to suffer from repeated miscarriages, scientists claim.
Researchers believe that swallowing sperm strengthens a pregnant woman's immune system in a way that makes fetuses more likely to grow healthily.
This could be, they say, because it contains hormones and proteins from the man's body, to which it can be useful for the mother to build up a tolerance.
Vaginal semen exposure – that is, unprotected sex – could also play an important role in a couple trying to conceive, but it is better to take semen into the gut.
Women who suffered from recurrent miscarriage, the loss of three or more babies in a row, were found in a study to give their partners less oral sex than those who did not suffer from the condition, who are believed to affects approximately one percent of women (stock image)
Researchers from the Leiden University Medical Center in the Netherlands have tested their theory by comparing the pregnancy history and oral sex habits of 234 women.
They acknowledged that the study was small and did not provide evidence that swallowing sperm led to a lower miscarriage.
But they believe that their results are strong enough to suggest a link between the two and justify more research.
97 of the women suffered from recurrent miscarriages – a condition in which a woman has three or more consecutive miscarriages.
The condition is believed to occur in approximately one in 100 women in the UK and possibly be caused by genetic or hormonal problems or by an infection. Many cases are unexplained.
In their study, the scientists found that women with regular miscarriages gave their partners considerably less fellatio.
While 73 percent of the women in the non-miscarriage group regularly gave oral sex, only 57 percent of those in the group with abuses did so.
& # 39; Oral exposure to seminal fluid appears to … positively influence the outcome of pregnancy & # 39 ;, the researchers wrote.
She added: & # 39; Our results suggest a link between less oral sex and the occurrence of recurrent miscarriages. & # 39;
By building up the mother's tolerance for substances from the man's body, the parents could give a fetus – made from the father's DNA – a better chance to thrive.
This could, according to the theory, make the mother's immune system less inclined to reject the baby and lead to death.
Research in the past may have focused too much on the mother's own biology, the scientists suggested, rather than the impact of the father's body fluids.
The study was published in the Journal of Reproductive Immunology.
HOW AT LEAST ONE IN SIX PREGNANCES FALLS IN A MIND
One in six pregnancies among women who know that they are pregnant is going to be miscarriages.
But more will happen to women who don't know they have a child.
Miscarriage is when a baby dies within the first 23 weeks after the pregnancy of a woman.
The main symptoms are bleeding from the vagina, which can be accompanied by pain in the lower abdomen.
There are several reasons why women can have a miscarriage – it is common and usually not caused by something they have done.
If a miscarriage occurs in the second trimester – between 14 and 26 weeks – this can be a sign of an underlying problem.
Miscarriages are often one-off events and women will continue to have successful pregnancies.
The majority of miscarriages cannot be prevented, but being generally healthy will help reduce the risk.
Losing three or more pregnancies in a row – known as recurrent miscarriages – is unusual, but still affects about one in 100 women.
