.....quite 'curious' to know?

Yes,believe it or not. I actually just watched a program on this on Discovery Health channel. A woman in India just gave birth to her first child at the age of 70, with the help of IVF. It also had several other women featured who gave birth in their late 50's and 60's. While women naturally go through menopause, there are medications that can help women to start having cycles again. I am not sure, but would say that this is the case in at least some of these women's cases.
