The sixth vital sign: what reproduction tells us about overall health. Proceedings from a NICHD/CDC workshop.

Study Question: Does the fertility status of an individual act as a biomarker for their future health?

Summary Answer: Data support an association between reproductive health and overall health for men and women.

What Is Already Known: Various chronic conditions, such as diabetes, obesity and cancer, can compromise fertility, but there are limited data for the converse situation, in which fertility status can influence or act as a marker for future health. Data reveal an association between infertility and incident cardiovascular disease and cancer in both men and women.

Molecular classification of endometriosis and disease stage using high-dimensional genomic data.

Endometriosis (E), an estrogen-dependent, progesterone-resistant, inflammatory disorder, affects 10% of reproductive-age women. It is diagnosed and staged at surgery, resulting in an 11-year latency from symptom onset to diagnosis, underscoring the need for less invasive, less expensive approaches. Because the uterine lining (endometrium) in women with E has altered molecular profiles, we tested whether molecular classification of this tissue can distinguish and stage disease.

Providing research and research training infrastructures for clinical research in the reproductive sciences.

The Reproductive Sciences Branch of the National Institutes of Child Health and Human Development has created pioneering new research and research training programs that address the impending shortage of physician-scientists in obstetrics, gynecology, and women's health and the need to bolster translational and clinical research. This article provides a brief overview of the Specialized Cooperative Centers Program in Reproduction Research, the National Cooperative Program for Infertility Research, the Reproductive Medicine Network, the Reproductive Scientist Development Program, the Women's Reproductive Health Research Career Development Program, and the Contraception and Infertility Research Loan Repayment Program and describes how these programs collectively create an infrastructure to promote the next generation of physician-scientists and to provide an information exchange between basic and clinical investigators. A key component in increasing the number of clinical investigators is the Contraception and Infertility Research Loan Repayment Program.

Phosphodiesterase 3 inhibitors selectively block the spontaneous resumption of meiosis by macaque oocytes in vitro.

Background: The purpose of this study was to determine whether phosphodiesterase (PDE) 3 inhibitors selectively prevent the resumption of meiosis in primates.

Methods: Immature oocytes (intact germinal vesicles) obtained from large pre-ovulatory follicles following ovarian stimulation in rhesus macaques were incubated with or without various doses of the PDE3 inhibitors, Cilostamide, Milrinone or ORG 9935, or a selective PDE4 inhibitor, Rolipram. Oocytes were observed for germinal vesicle breakdown (GVBD) as an indicator of resumption of meiosis.
