Occurrence of preeclampsia : Protective influence from previous pregnancy terminated by abortion and absence of the protective influence preconceptional exposition to partner's sperm

The purpose of this study was to verify a hypothesis saying than pre-conception exposition to partner's sperm reduces a risk of preeclampsia outbreak in primiparas. A questionnaire was passed to 261 still childless women, now in 30th week of pregnancy. This questionnaire included questions on a frequency of coitus and method od contraception used, by both present partner and other men before. On the base of these information, we calculated a number of coitus, non-protected by barrier methods of contraception. In addition to that, we were asking about eventual preceding aborted pregnancies. After childbirth, the authors evaluated an occurrence of preeclampsia. Preeclampsia was defined as an occurrence of higher blood pressure, i.e. over 140/90 mmHg, in two different days. This condition was found in 27 women, i.e. 10.34%. No statistically significant difference was found between a group of women, in which preeclampsia had developed, and a group of healthy women, as for number of coitus without barrier contraception, neither in case of a present partner (210.0:231.1), nor in case of other men (114.9 : 69.4). However, the groups differ in a number of preceding aborted pregnancies (We did not distinguish spontaneous and artificial abort), in the case of both - present partner (0.215:0.037, p < 0.01), and other men (0.219:0.037, p < 0.01). The autors conclude, that pre-conception exposition to sperms shows no protective effects on outbreak of preeclampsia in primiparas, the risk of which is reduced considerably by preceding abort, spontaneous or artificial.
