Department of Infertility, Shariati Hospital, Tehran University of Medical Sciences Abstract Background: Anti-Mullerian hormone (AMH) is identified as a member of the transforming growth factor β and is produced by the granulose cells of preantral and small antral follicles. AMH is undetectable in neonates but increases gradually during puberty and remains stable throughout the reproductive ages. It is believed that decline in serum levels of AMH, is the first indication of a decreased ovarian reserve. AMH has been suggested as a marker of ovarian reserve and predictor of ovarian response to controlled ovarian hyper stimulation. The aim of this study is to determine the role of AMH in prediction of success ART cycles in patients with normal FSH serum levels. The aim of this study is to determine the role of AMH in prediction of success ART cycles in patients with normal FSH serum levels. This prospective cohort study included 80 infertile women under 4o years, who candidates for assisted reproductive technique. Serum AMH levels on cycle day 3 were measured and all the patients underwent controlled ovarian hyper stimulation and ART. The relationship between serum AMH and ART outcomes, including oocytes number, matured oocytes, fertilization rate, implantation rate, high quality embryo, free zed embryo and biochemical and clinical pregnancy rates were evaluated. Cut-off for level of AMH in this level pregnancy is high, determined. Serum basal AMH levels showed positive correlation with number of oocytes retrieved, mature oocytes, number of embryos transferred and biochemical and clinical pregnancy. Cut-off for serum AMH with and without clinical pregnancy was 3.9.This study showed that in pregnant women undergoing ART, AMH serum levels were higher than non pregnant women. Key words: Anti-Mullerian hormone, Assisted reproductive technology, outcomes, Follicle stimulating factor. Results Material and Methods This prospective cohort study included 80 infertile women under 4o years, who candidates for assisted reproductive technique. Serum AMH levels on cycle day 3 were measured and all the patients underwent controlled ovarian hyper stimulation and ART. Patients were on the long protocol for ART, down regulation was achieved with GnRH agonist (buserelin) and stimulation was initiated with hMG and Gonal-f. In all patients, when matured follicle reached a diameter of 18 mm, IU of hCG was injected. Oocyte retrieved was carries out transvaginally 36h after hCG administration. The relationship between serum AMH and ART outcomes, including oocytes number, matured oocytes, fertilization rate, implantation rate, high quality embryo, free zed embryo and biochemical and clinical pregnancy rates were evaluated. Cut-off for level of AMH in this level pregnancy is high, determined. Serum basal AMH levels showed positive correlation with number of oocytes retrieved, mature oocytes, number of embryos transferred and biochemical and clinical pregnancy. There is positive and significant relationship between serum basal AMH levels and total oocytes retrieved and matured oocytes. Serum AMH levels were positively and significantly correlated with clinical pregnancy. Cut-off for serum AMH with and without clinical pregnancy was 3.9, with 75% sensitivity and 55% specifity. Conclusion This study showed that in pregnant women undergoing ART, AMH serum levels were higher than non pregnant women. The results suggest that a serum basal AMH level is prediction of oocytes quantity and quality.
