Patient factors that influence both menstruation and stroke risk include coagulopathies, polycystic ovarian syndrome, endometriosis, migraine, and other systemic disorders, in addition to menopause. Environmental and iatrogenic factors that influence both menstruation and stroke risk include hormonal contraceptives, nicotine, xenoestrogens, phytoestrogens, oophorectomy, and hysterectomy.
