Objective To compare outcome parameters and cumulative pregnancy rates (PRs) in oocyte donation cycles over a period of 10 years. Design Retrospective study. Setting University-affiliated assisted reproductive technology program. Patient(s) Women undergoing oocyte donation (10,537 cycles) between 1995 and 2005. Intervention(s) Ovarian stimulation and oocyte retrieval in donors. Embryo transfer performed in recipients after endometrial preparation. Main Outcome Measure(s) Outcome parameters and cumulative PRs were calculated and compared in relation to indication, age, and origin of sperm used. Result(s) Overall PR, implantation rate, clinical PR, and miscarriage rate per embryo transfer per…

Interactions of the hormones leptin, ghrelin, adiponectin, resistin, and PYY3-36 with the reproductive system.

2006

Objective To summarize the effects of novel hormones (leptin, ghrelin, adiponectin, resistin, and PYY3-36) secreted from adipose tissue and the gastrointestinal tract that have been discovered to exert different effects on several reproductive functions, such as the hypothalamic–pituitary–gonadal axis, embryo development, implantation physiology, and clinically relevant conditions. Design A MEDLINE computer search was performed to identify relevant articles. Result(s) Leptin and ghrelin exert important roles on body weight regulation, eating behavior, and reproduction, acting on the central nervous system and target reproductive organs. As a marker of adequate nutritional stores, these horm…
