Advanced menopause

A protein of female mice causes eggs to develop at the right time, according to new research. Mammalian females have all their eggs from birth, and then, monthly, some eggs or follicles go to the ovary and begin to develop. Under normal conditions, women are around 50 years old without follicles.

1%, however, has menopause by age 30. To investigate advanced menopause they have been tested in mice and have seen that the protein Foxo3a may have something to say in the disease. In fact, this protein causes in each cycle too many follicles to the ovaries, so the female stays before without eggs.
