Ovulation News and Research

RSS

Ovulation is the process in a female's menstrual cycle by which a mature ovarian follicle ruptures and discharges an ovum (also known as an oocyte, female gamete, or casually, an egg). Ovulation also occurs in the estrous cycle of other female mammals, which differs in many fundamental ways from the menstrual cycle. The time immediately surrounding ovulation is referred to as the ovulatory phase or the periovulatory period.

Effects of allopregnanolone in women with severe pre-menstrual syndrome

Sensitivity to allopregnanolone, a hormone that occurs naturally in the body after ovulation and during pregnancy, changes during the course of the menstrual cycle and is different in women with severe pre-menstrual syndrome (PMS) compared with women without PMS complaints. This has been shown by Erika Timby in her doctoral dissertation recently defended at Umeå University, Sweden.

Longer looks: Doctors advocating less care; addiction as a 'disease'

These physicians are not anti-medicine. They are not trying to save money on their copayments or deductibles. And they are not trying to rein in the nation's soaring health-care costs, which at $2.7 trillion account for fully one sixth of every dollar spent in the U.S. They are applying to their personal lives a message they have become increasingly vocal about in their roles as biomedical researchers and doctors: more health care often means worse health.

Reproductive steroids may play a role in occurrence of generalized tonic-clonic seizures in women

A recent multi-center study determined that women with generalized tonic-clonic seizures (GTCS) had a greater number of seizures during anovulatory cycles-menstrual cycles where an egg is not released-than in cycles where ovulation occurs. According to the study publishing today in Epilepsia, a journal of the International League Against Epilepsy (ILAE), reproductive steroids may play a role in GTCS occurrence.
