New research from Roskilde Hospital in Denmark shows that male sperm contains a special protein that seems to prevent pregnancy induced hypertension (PIH), and suggest that condom-free and oral sex can be beneficial in avoiding PIH.
Roskilde Hospital Consultant Physician Thomas Hviid and Ph.D. student Snezana Djurisic have investigated why some women seem to have a higher risk of PIH – which is also known as preeclampsia or toxaemia – than others.
