Seizures in many females are increased in their frequency in relation to the menstrual cycle. Logothetis et al4 postulated that a premenstrual exacerbation of seizures might be related to increased estrogenic activity. A lowering of electroshock threshold during estrus in the rat has been related to high levels of circulating estradiol during this phase.5 The exact relation of circulating estrogenic substances to seizure exacerbations in the human
