There are individuals who suffer from premature menopause and have a reduced ovarian reserve. I think these sort of advances would be beneficial for those individuals or perhaps those who have undergone chemotherapy treatment.

I do agree that by and large menopause is a conserved process in humans which limits our reproductive window. This is beneficial as we may be able to extend this reproductive window but we cannot reverse other adverse effects of aging. To continue to reproduce older contributes to poorer health in those individuals in my opinion and makes children orphans earlier in life.
