Purpose: We performed a prospective randomized study to assess the effects of a GnRH agonist (GnRH-a) onfollicular development and steroidogenesis during controlled ovarian hyperstimulation (COH). Methods: Patients undergoing in vitro fertilization (IVF)for tubal infertility received human menopausal gonadotropin (hMG) stimulation with or without the(More)
The effects of PRL on fertilization and cleavage of human oocytes and subsequent pregnancy were studied. Forty-five patients (47 cycles) with euprolactinemic normal menstrual cycles undergoing in vitro fertilization (IVF) for the treatment of tubal infertility were selected for this study. The patients were divided into three groups dependent upon their(More)
Human follicular fluids from normal women and from women with polycystic ovary syndrome (PCOS) were collected at various stages of the menstrual cycle, and inhibin and steroid contents were determined by rat anterior pituitary cell monolayer bioassay system and specific RIAs, respectively. Inhibin contents in viable follicles were significantly higher than(More)
The present study was undertaken to evaluate the role of corpus luteum function in the implantation process of cryopreserved embryos. Six patients with tubal infertility were studied, with a total of 27 fresh embryos being replaced following controlled ovarian hyperstimulation and in vitro fertilization. These embryo transfers failed to produce pregnancy.(More)
