Abstract
BACKGROUND: Infertility treatments with oocyte donation are becoming frequent. Recruitment of oocyte donors is a demanding and costly process and therefore of crucial importance. The selection of the oocyte donors undergoes a rigorous evaluation process of the candidates with routine measurement of the anti-Müllerian hormone (AMH) levels (ovarian reserve test). Our aim was to assess whether AMH levels could act as a good marker as tool to select the donor candidates and correlate them with the ovarian response to stimulation with a gonadotropin-releasing hormone antagonist protocol as well as to identify and validate the appropriate AMH level threshold by correlating it with the number of oocytes retrieved. METHODS: A retrospective analysis of the oocyte donors' clinical records was performed. RESULTS: The mean age of the participants was 27 years. The ovarian reserve evaluation showed a mean AMH of 5.20 ng/mL. An average number of 16 oocytes was retrieved (12 mature oocytes MII). AMH levels showed a statistically significant positive correlation with the number of total oocytes retrieved. A threshold value of AMH = 3.2 ng/mL predictive of the retrieval <12 oocytes (areas under the curve, 0.7364; 95% confidence interval: 0.529-0.944) was identified by receiver operating characteristic curve. Using this cutoff, the normal response (12 oocytes) was predicted with a sensitivity of 77% and a specificity of 60%. CONCLUSIONS: The measurement of AMH may be a determining factor in the choice of the oocyte donor candidates to maximize the response to requests from beneficiaries who require donor oocytes to perform assisted reproductive technique cycles.
