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.

First Evidence of Oocyte Cohesion Rejuvenation Discovered in Fruit Flies

A Dartmouth study conducted on fruit flies reports the first evidence in any organism that oocytes-;the cells that become eggs-;regularly rejuvenate the critical protein linkages that bind chromosomes together.

Researchers Use the Bionanoprobe to Explore Role of Zinc in Follicle Development

The discovery that zinc is involved in the fertilization process earlier than initially thought was made with the help of the Bionanoprobe, a cutting-edge instrument at Argonne.

Study sheds light on unique processes that bestow naked mole-rats’ with eternal fertility

Unlike humans and other mammals, which become less fertile with age, naked mole-rats can reproduce throughout their remarkably long lifespans.

Novel model system helps studying human ovarian biology

Despite the fact that we all start out as an egg cell in one of our mother's ovaries, these human reproductive organs are surprisingly under-studied. Scientists have been working on creating in vitro models of human ovaries so that we can learn more about them and develop treatments for ovarian conditions, but most existing models use a combination of human and mouse cells, which do not faithfully replicate human ovary functions and take a long time to grow in the lab.

Rumen-protected lysine improves uterine health

Boosting milk yield when included in the diet at sufficient levels, lysine is an important amino acid for dairy cows. But how could lysine be advantageous for cows in other means? A new study by the University of Illinois reveals that rumen-protected lysine can enhance uterine health if given in the transition period.

More informed choices of contraceptives can prevent breast cancer

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.
