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...

Researchers have discovered that some women carry a genetic variation that makes them sub-fertile and less likely to respond to ovarian stimulating hormones during fertility treatment. The discovery opens the way to identifying these women and devising personalized fertility treatments that could bypass the problem caused by the genetic abnormality. Dr Maria Lalioti told the 26th annual meeting of the European Society of Human Reproduction and Embryology in Rome on Tuesday (June 29) that she...

Researchers from the National Institutes of Health and other institutions have identified in mice two proteins essential for ovulation to take place.The finding has implications for treating infertility resulting from a failure of ovulation to occur as well as for developing new means to prevent pregnancy by preventing the release of the egg.The proteins, called ERK1 and ERK2, appear to bring about the maturation and release of the egg.The study, appearing in the May 15 issue of Science, was...

Two enzymes called extracellular signal-regulated kinases (ERK1 and ERK2) are critical factors in a pathway that induces ovulation, maturation of the mammalian egg (oocyte) and other activities key to ovarian function and female fertility, said a group of researchers at Baylor College of Medicine (BCM) in a report that appears today in the journal Science."This finding could provide clues to developing new contraceptives and understanding infertility in some women with irregular menstrual...
