New NZ study indicates that condom use is detrimental to female health

Women in longterm relationships apparently have healthier pregnancies – possibly because of longterm exposure to the sperm of the baby’s father, an Auckland survey has found.

An earlier study of the role of sperm in the development of pre-eclampsia, published in the American Journal of Obstetrics and Gynaecology, found a higher risk for women who had been living with the baby’s father for less the four months and using barrier methods for contraception.

Several other studies have found a lower incidence of pre-eclampsia in women who had received blood transfusions from their partner, those with long, preceding histories of sex without barrier contraceptives.

The female immune system was boosted by exposure to “paternal antigens”, beneficial antibodies in the male sperm, said Larry Chamley, an Associate Professor of Obstetrics and Gynaecology at Auckland University, who was not involved in the study.

“The issue of whether prolonged semen exposure does protect against developing pre-eclampsia is not yet resolved, this paper seems to tip the weight of evidence back in favour of suggesting that prolonged semen exposure is protective,” he said.
