Preeclampsia, a serious pregnancy complication causing fetal and maternal fatalities, is being re-examined by Pierre-Yves Robillard, a neonatologist and epidemiologist, who believes preeclampsia is caused by unfamiliarity with new paternal genetic material, not pregnancy. This implies that exposure to a partner’s semen could reduce the risk of preeclampsia. While some researchers acknowledge this “paternal-immunity hypothesis,” others claim alternative factors may be involved. Ultimately, continuing research is necessary to improve treatment and diagnostics for preeclampsia.
