Update in female reproduction: a life-cycle approach.
BACKGROUND
Female reproduction spans a developmental life arc from fetal life and childhood, through puberty to the reproductive years, and, finally, ovarian follicle depletion and the onset of menopause.


OBJECTIVE
This invited review highlights a selection of reports from leading journals over the past 2 yr that have significantly advanced our understanding of female reproduction from conception to menopause.


RESULTS
During fetal life, in utero exposures may be important determinants of later pubertal and adult endocrine physiology. Epigenetic mechanisms are likely involved in the fetal programming of adult endocrine function. With regards to the polycystic ovary syndrome, recent clinical trials have confirmed the central role of clomiphene for ovulation induction in women with this disease. In addition, an expert panel has recommended that all women with polycystic ovary syndrome have a glucose tolerance test because of the high prevalence of impaired glucose tolerance in this population. In menopausal women the precise impact of estrogen therapy on cardiovascular biology remains to be delineated fully. Evolving data indicate that when initiated near the onset of menopause, estrogen therapy has fewer cardiovascular risks than when it is administered decades after the menopause.


CONCLUSIONS
The essence of reproduction is the successful transmission of germ-line DNA to a succeeding generation. Advances in genetics and endocrinology are converging to advance significantly our understanding of the biology of reproduction and our ability to influence reproductive processes. These advances will translate into new treatments for the prevalent medical problems of reproduction.
