Women are more likely to suffer recurrent miscarriages if their first child is a boy

who gave birth to a boy in their first pregnancy go on to have a second child. However this percentage is lower than for those who gave birth to a girl first. Among my patients I have at least 50 who never have a second child after the first birth of a boy, whereas approximately 20 patients did not experience another birth after having a girl. So there are patients who will never get a second child in both groups, but the risk is larger among women whose first child was a boy."

He believes that the way women's immune systems react to male foetuses is the explanation for his finding and that therefore it will be possible to treat successfully women who suffer from SRMs. "These women may have raised an immunological reaction against tissue types that are expressed on the surface of the placenta in pregnancies with boys," he said. "The placenta is created from the foetus and if it is a boy it will carry these male-specific tissue types. The mother's immune system may be reacting by forming antibodies, but also the mother's white blood cells may be reacting against the placenta."

The first pregnancy is able to proceed to full term because the pregnancy is safely established by the time the mother's immune system starts to react to the male foetus. However, it is possible that the immune systems remains activated after delivery and affects subsequent pregnancies, believes Dr Christiansen.

"This is an epidemiological study, so we cannot be sure that such an immunological reaction is the explanation for our findings. However, no genetic disorder following the known rules of inheritance, can explain the findings. The impact of the gender of the first-born child on successive pregnancies is suggestive of something that has memory and only two tissues in the body are thought to have memory: the central nerve system and the immune system. Together with a PhD student, I have planned a series of genetic studies and immunological experiments to confirm or
