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.

New book on evolution and future of human reproduction

Human beings would probably be known as pilosals rather than mammals if Carl Linnaeus had not been a proponent of breast-feeding. For social and political reasons, the famed taxonomist labeled the class of animals to which humans belong with a reference to their practice of suckling their young rather than to their evolutionarily older characteristic of having hair.

Managing insulin levels through meal timing boosts ovulation in women with PCOS

Polycystic Ovarian Syndrome (PCOS), a common disorder that impairs fertility by impacting menstruation, ovulation, hormones, and more, is closely related to insulin levels. Women with the disorder are typically "insulin resistant" - their bodies produce an overabundance of insulin to deliver glucose from the blood into the muscles.

Children born after mothers hormonal fertility treatment have increased risk of mental disorders

Whether a child is conceived naturally or in a Petri dish in an incubator has no bearing at all on the child's mental health. However, researchers have identified a small but increased risk of developing a mental disorder such as autism, ADHD or behavioural problems in children whose mothers only received medical treatment to stimulate ovulation and egg development before insemination.

Study shows female obesity may reduce receptivity of uterus to embryo implantation

An analysis of almost 10,000 first cycles of egg donation treatment at one of Europe's largest IVF centres shows that female obesity reduces the receptivity of the uterus to embryo implantation and thereby compromises reproductive outcome.

New low-cost method of in-vitro fertilization may help infertile couples in developing countries

A new low-cost method of in-vitro fertilization developed at the University of Colorado Boulder that performed successfully in recent human clinical trials in Belgium may help thousands of infertile couples in developing countries.

Protein in liver plays a crucial role in mice's pregnancy and human menstrual cycle

A protein first shown to function in the liver plays a crucial role in pregnancy in mice and has a key role in the human menstrual cycle, according to researchers at the University of Montreal. Mice that were genetically engineered not to produce the liver receptor homolog-1 (Lrh-1) molecule were unable to create the uterine conditions necessary for establishing and sustaining pregnancy, resulting in the formation of defective placentas.

FDA approves use of Plan B One-Step pill for all women with child-bearing potential

Today, the U.S. Food and Drug Administration announced it has approved the use of Plan B One-Step (levonorgestrel) as a nonprescription product for all women of child-bearing potential.

Women with polycystic ovary syndrome lose more weight when they take two drugs

Women with polycystic ovary syndrome, or PCOS, lost significantly more weight when they took two drugs that are traditionally used to treat diabetes, rather than either drug alone, a study from Slovenia demonstrates. The results will be presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco.

kisspeptin hormone effectively induces egg maturation during infertility treatment, shows study

The naturally occurring hormone kisspeptin effectively induces egg maturation during infertility treatment, according to a clinical in vitro fertilization (IVF) study. The results were presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco.

Study: Vitamin D supplementation may help delay early onset of puberty in girls

Vitamin D supplementation may help delay early onset of puberty in girls, a new clinical study finds. The results were presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco.

Research show potential link between psychological vulnerability and timing of menstrual cycle

Women at a particular stage in their monthly menstrual cycle may be more vulnerable to some of the psychological side-effects associated with stressful experiences, according to a study from UCL.

New research sheds light on successful ovulation and fertilization

Eggs take a long time to produce in the ovary, and thus are one of a body's precious resources. It has been theorized that the body has mechanisms to help the ovary ensure that ovulated eggs enter the reproductive tract at the right time in order to maximize the chance of successful fertilization.

Relationship between obesity and PCOS may be exaggerated, say researchers

The relationship between obesity and polycystic ovary syndrome may be exaggerated, likely because the women who actively seek care for the condition tend to be heavier than those identified through screening of the general population, researchers report.

Researchers discover injectable protein to reverse symptoms of dangerous conditions

The creation of new blood vessels in the body, called "angiogenesis," is usually discussed in connection with healing wounds and tumors. But it's also an ongoing process in the female reproductive tract, where the growth and breaking of blood vessels is a normal part of the menstrual cycle. But abnormal growth of blood vessels can have painful consequences and resultant pathologies.

Study provides new insights about polycystic ovarian syndrome, insulin resistance

A group of tiny RNA molecules with a big role in regulating gene expression also appear to have a role in causing insulin resistance in woman with polycystic ovary syndrome and, perhaps, in all women, researchers report.

Researchers discover ovarian stem-like epithelial cells that can mutate to form tumors

In collaboration with colleagues at Cornell University, a team of cancer researchers at Cold Spring Harbor Laboratory (CSHL) has discovered cells with stem-cell properties in the ovary that can mutate to form tumors.

Study finds major risk factor behind increased risk of adverse outcomes in IVF pregnancies

Massachusetts General Hospital (MGH) researchers have identified what may be a major factor behind the increased risk of two adverse outcomes in pregnancies conceived through in vitro fertilization (IVF).

Mich. panel strips abortion from Blue Cross bill; Ark. House takes action

A House panel on Thursday overwhelmingly approved legislation to overhaul Blue Cross Blue Shield of Michigan, leaving out anti-abortion provisions that torpedoed an earlier effort to change the status of the state's largest health insurer. The 11-0 votes signaled -; at least for now -; that one of Republican Gov. Rick Snyder's top legislative priorities could reach his desk without language that led him to veto similar legislation in late December. The Senate OK'd the new Blue Cross bills in late January.

High anti-M-llerian hormone levels signal increased likelihood of pregnancy, birth

Women with a high concentration of anti-M-llerian hormone stand a better chance of giving birth after in vitro fertilization, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

FDA approves Takeda’s NESINA, OSENI and KAZANO for treatment of type 2 diabetes

Takeda Pharmaceutical Company Limited and its wholly-owned subsidiary, Takeda Pharmaceuticals U.S.A., Inc. today announced that the United States (U.S.) Food and Drug Administration (FDA) has approved NESINA (alogliptin) and the fixed-dose combination (FDC) therapies OSENI (alogliptin and pioglitazone) and KAZANO (alogliptin and metformin HCl) for the treatment of type 2 diabetes in adults as adjuncts to diet and exercise.
