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.

Anti-Müllerian hormone plays an active role in polycystic ovary syndrome

High levels of anti-Mullerian hormone (AMH) have traditionally been thought of as merely a passive byproduct of polycystic ovary syndrome (PCOS), but a new preclinical study by Weill Cornell Medicine researchers suggests that the hormone plays an active role in the disorder and may contribute to problems with ovulation and fertility.

Research finds variability in PTSD symptoms over the course of menstrual cycle

In women who have experienced trauma, post-traumatic stress disorder symptoms may vary over the course of the menstrual cycle, with more symptoms during the first few days of the cycle when the hormone estradiol is low, and fewer symptoms close to ovulation, when estradiol is high, finds research published by the American Psychological Association.

Can molecular mimicry impact fertility in female COVID-19 patients?

There exists a possibility that COVID-19 can also affect the reproductive function in the body, which can lead to infertility in infected patients. A study published in the American Journal of Reproductive Immunology explored the impact of SARS-CoV-2 infection on reproductive functions and fertility.

Study shows that breast cancer can be prevented with better contraception choices

Hormonal contraceptives, e.g. the pill, the patch, and the vaginal ring, contain synthetic hormones that prevent pregnancy by either stopping ovulation, changing the cervical mucus to stop sperm from passing through the cervix and finding an egg, or changing the womb's lining to prevent a fertilized egg from being implanted in it.
