A number of oocyte characteristics have been associated with fertilization, implantation and live-birth rates, albeit without reaching a consensus. This study aims to delineate possible associations between oocyte characteristics, oocyte be…
BACKGROUND: The KISS1/KISS1R system has been implicated in the physiology of reproduction and many studies have documented the stimulatory effect of kisspeptin on Gonadotropin-releasing Hormone (GnRH) and gonadotropin secretion. In addition…
BACKGROUND: The peritoneal fluid (PF) of women with endometriosis contains protease(s) activity able to hydrolyze insulin-like growth factor-binding protein 3 (IGFBP-3), increasing the bioavailability of insulin-like growth factor-1 (IGF-1)…
OBJECTIVE: To evaluate the expression of insulin-like growth factor-binding protein-3 (IGFBP-3) in the eutopic endometrium and in endometriotic lesions. DESIGN: Retrospective immunohistochemical study. PATIENT(S): Twenty-five normal women…
BACKGROUND: Recent data indicate the implication of an IGF/IGFBP/protease system in the development of ectopic implants of endometrium (endometriosis) in the pelvic cavity. MATERIAL AND METHODS: We characterized mitogens and protease(s) ag…
OBJECTIVE: To characterize and purify peritoneal mitogens able to stimulate the proliferation of human endometrial cells in vitro. DESIGN: Peritoneal fluids (PFs) from 50 patients were collected at laparoscopy and pooled (270 mL) for purif…
OBJECTIVE: To characterize and to purify the growth substances for mouse embryo fibroblasts (NIH/3T3) and endometrial-like cells of the peritoneal fluid of women with endometriosis. DESIGN: A pool of 102 mL of peritoneal fluid (PF) collect…
OBJECTIVE: To characterize the presence of mitogen(s) in the peritoneal fluid (PF). DESIGN: Aliquots of PF aspirated at laparoscopy were assessed for mitogenic activity by the rate of [3H]-thymidine incorporation into the deoxyribonucleic …
