Ovaries are female reproductive organs that are responsible for the production of ova or eggs. These are necessary for normal fertilization and development of the fetus. Fertility of a woman can be jeopardized when the ovaries do not function normally. Danish researchers have now successfully engineered artificial ovaries that could help millions of women with infertility related to ovarian disease and cancer therapy.
Aging leads to large changes in gene activity in the ovaries of mice, but only limited changes in testes, according to research published in the open-access journal, BMC Biology.
According a US fertility expert, young women should freeze parts of their ovaries if they want to postpone motherhood until later in life. This advice came from Dr Sherman Silber at the American Society for Reproductive Medicine meeting in Denver.
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.
In research that could have broad implications for women's fertility treatments, scientists have found that despite their age, female mice have a renewable egg supply in their ovaries.
Using a new technique developed at Drexel University College of Medicine in Philadelphia, Stephanie A. King, M.D., Associate Professor and Chief of Gynecologic Oncology, removed a woman's ovaries through a single incision in the patient's belly button.
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 follicles that contain growing eggs.
Researchers at Universitat Aut-noma de Barcelona, in collaboration with the Vall d'Hebron Hospital Fetal Tissue Bank, the Department of Gynaecology and the Research Unit of Paediatric Endocrinology, analysed the effects of Bisphenol A (BPA), a polymer widely used to manufacture plastics, in an in vitro culture of ovaries.
