The stresses that come with aging, chemotherapy treatments, and environmental exposures all threaten fertility. But what if there were a way to preserve women's limited egg supply? Researchers reporting on studies conducted in frog and mouse eggs in the Cell Press journal Molecular Cell on October 3rd may have found a way. The findings come at an important time when many women are waiting longer and longer to have children, renewing interest in the development of strategies to preserve...

Women feel positive about it, even though many believe they will never use the eggs they have stored Egg freezing as insurance against age-related infertility is a growing trend in many countries. Women who bank oocytes for use at some time in the future hope to buy a little time in their search for a suitable partner. However, a study from one of Europe's largest centres in reproductive medicine suggests that many of those banking eggs believe they will never use them - even though...

Mammalian females ovulate periodically over their reproductive lifetimes, placing significant demands on their ovaries for egg production. Whether mammals generate new eggs in adulthood using stem cells has been a source of scientific controversy. If true, these "germ-line stem cells" might allow novel treatments for infertility and other diseases. However, new research from Carnegie's Lei Lei and Allan Spradling demonstrates that adult mice do not use stem cells to produce new eggs. Their...

New research from the University of Adelaide will rewrite the textbooks on how an ovary is formed, as well as providing new insights into women's health and fertility. The study, now published in the journal PLOS ONE, also names a new type of cell that plays a key role in the development of ovaries and ovarian follicles, which are responsible for the production of eggs in women. The discovery is expected to prompt further studies around the world to better understand how ovaries and...

(Ivanhoe Newswire) — Is your biological clock about to run out? While women have always thought they are born with all of the eggs they need, new research says, that´s not true! A compelling new genetic study tracing the origins of immature egg cells, or 'oocytes', from the embryonic period throughout adulthood adds new information to a growing controversy. The notion of a "biological clock" in women arises from the fact that oocytes progressively decline in number as females...

Researchers at Brown University and Women & Infants Hospital have invented the first artificial human ovary, an advance that provides a potentially powerful new means for conducting fertility research and could also yield infertility treatments for cancer patients. The team has already used the lab-grown organ to mature human eggs. "An ovary is composed of three main cell types, and this is the first time that anyone has created a 3-D tissue structure with triple cell line," said Sandra...

Implications for treatment of polycystic ovarian syndrome, No. 1 cause of female infertility Male sex hormones, such as testosterone, have well defined roles in male reproduction and prostate cancer. What may surprise many is that they also play an important role in female fertility. A new study finds that the presence and activity of male sex hormones in the ovaries helps regulate female fertility, likely by controlling follicle growth and development and preventing deterioration of...

Virginia Commonwealth University researchers have identified the role of a gene in regulating molecular signals involved with ovarian follicle development, which may one day help shed light on some of the causes of fertility issues in humans. The steps involved with conception and pregnancy are delicate and complex "“ particularly the process of folliculogenesis. In females, fertility is dependant on the growth of a follicle, a structure that ultimately transforms to release a mature...

The tiny translucent egg nestled in the special laboratory gel was a mere 30 days old, but its four-week birthday caused researchers to quietly celebrate. This was the first time anyone had successfully grown a woman's immature egg cells, contained in a tiny sac called a follicle, to a healthy and nearly mature egg in the laboratory. When an egg is fully mature, it is ready to be fertilized.The researchers from Northwestern University Feinberg School of Medicine have completed the first...

The ovaries are the two reproductive female organs where the eggs are produced. These are parallel to the testes in men. Formation and Orientation Each ovary is the size of an almond and is located on one side of the pelvis before the ureter and internal iliac artery but after the external iliac artery. They are attached to either side of the uterus. They are connected and release eggs to fallopian tubes, though not attached, monthly during the menstrual cycle. They also produce...
