Infertility can be very frustrating for couples who want so much to have children. It brings new hope therefore, whenever research brings about new information that could impact positively in this regard.
There is good news then for infertile couples, because, according to an article in the June 2013 issue of FASEB Journal, scientists seem to have just discovered an hormone which could make ovaries grow, for couples not responding well to Follicle Stimulating Hormone (FSH). This would mean more infertility treatment options.
"To make this discovery, Hsueh and colleagues analyzed all the proteins likely made by the eggs, and discovered a previously unknown hormone, called R-spondin2. The researchers then replicated this new hormone in test tubes and injected it into mice. The hormone stimulated growth of mouse ovarian cells, leading to the generation of mature eggs. These eggs were fertilized and led to successful pregnancies and the delivery of healthy pups. Then, human ovarian tissue was grafted into mice, and this also grew after treatment with this newly identified ovarian hormone, suggesting that the hormone could work in humans."
