Early Menopause: A Mouse Model Of Human POI

Science Daily,  Sept 4, 2012

Scientists have established a genetic mouse model for primary ovarian insufficiency (POI), a human condition in which women experience irregular menstrual cycles and reduced fertility, and early exposure to estrogen deficiency.

POI affects approximately one in a hundred women. In most cases of primary ovarian insufficiency, the cause is mysterious, although genetics is known to play a causative role. There are no treatments designed to help preserve fertility. Some women with POI retain some ovarian function and a fraction (5-10 percent) have children after receiving the diagnosis.

Having a mouse model could accelerate research on the causes and mechanisms of POI, and could eventually lead to treatments, says Peng Jin, PhD, associate professor of human genetics at Emory University School of Medicine.

The results were published online recently in the journal Human Molecular Genetics.
