I'm 42 years old and just experienced the first signs of menopause. Is there any treatment that can postpone it?

Our ovaries have a built-in clock, so the timing of menopause is likely genetically predetermined long before the first signs of menopause appear. Hormonal treatment, such as birth control pills, may mask the signs and symptoms of menopause but ultimately will not postpone it. Certainly, there are some exposures in our life that may hasten the timing of menopause, such as chemotherapy, pelvic radiation or surgical removal of the ovaries. But there is no reliable "fountain of youth" that can stop the inevitable decline in ovarian hormone production or fertility.
