The association between anti-Müllerian hormone and IVF pregnancy outcomes is influenced by age.

The conflicting results from studies on the predictive capabilities of serum anti-Müllerian hormone (AMH) for IVF pregnancy outcomes may be attributed to small sample sizes and disparities in the age of the study populations. The relationship between AMH and IVF pregnancy outcomes was clarified with retrospective cross-tabulation analyses (n=1558) stratified by age to control for its confounding effects. Serum AMH concentrations were divided into tertiles (≤ 0.

Characteristics of the urinary luteinizing hormone surge in young ovulatory women.

Objective: To define characteristics of the luteinizing hormone (LH) surge in urine.

Design: Observational study.

Setting: Academic center.

Ovulatory status and follicular response predict success of clomiphene citrate-intrauterine insemination.

Objective: To test the hypothesis that anovulatory women would have good pregnancy rates (PRs), regardless of single or multiple follicular development, in response to clomiphene citrate (CC), whereas ovulatory women would have good PRs only when achieving multifollicular responses to CC.

Design: Retrospective chart review.

Setting: University-based infertility center.

Menopause and hypothalamic-pituitary sensitivity to estrogen.

Context: The onset of human menopause is thought to be caused solely by ovarian failure and oocyte depletion. However, clinical symptoms and certain recent data in perimenopausal women suggest central nervous system involvement.

Objective: To determine if modifications of hypothalamic-pituitary response to estrogen feedback mechanisms occur in older reproductive-age women as a mechanism of the onset of menopause.

Age-related changes in the regulation of luteinizing hormone secretion by estrogen in women.

Despite the many studies that have been conducted using both primate and human models to understand the control of the menstrual cycle, there are many aspects of the hormonal dynamics of the menstrual cycle that are not understood. This Minireview summarizes the changes in estrogen regulation of luteinizing hormone (LH) secretion that occur throughout life in women from the time of maturation of the hypothalamic-pituitary axis resulting in the occurrence of the LH surge during puberty, through the reproductive years, to the changes in the regulation of the LH surge during premenopause and, subsequently, menopause.
