Estrogen cuts aneurysms.

Extra estrogen, in the form of oral contraceptive or as part of hormone replacement therapy, cuts the risk of brain aneurysms in post-menopausal women.

An aneurysm is a blood-filled bulge in a blood vessel, caused by disease or weakening of the vessel wall.

Dr Michael Chen noted that the two largest trials of head aneurysms showed that the most frequent victims were post-menopausal women. So he compared 60 women with aneurysms against 4,700 controls.

Oral contraceptives were used by 60% of the aneurysm group compared to 77% of the control group, and for only half the duration of use by the control group.

HRT use was 27% for the aneurysm group, compared to 45% for the controls.

According to Chen “This study provides another piece of evidence that estrogen stabilisation may play a protective role in women who are at risk of aneurysms.”
