The objective of our study is to determine if there is any correlation between blood AMH levels before the pregnancy and adverse pregnancy outcomes in a subfertile population.

The study will be a retrospective review of patient records of women who had AMH levels checked and delivered at AUBMC.

 Data will be collected by review of medical records of all women presenting to one of the physicians in the division of Reproductive Endocrinology and Infertility (JA, GG, A.A-M, and AH) who conceived and delivered between January 1, 2008 and January 1, 2016.

 Women who had an AMH level available before pregnancy will be identified. The information that will be collected will include maternal age, paternal age, parity, weight, AMH level, use of assisted reproductive techniques (ART), history of failed ART, pre-existing medical conditions such as diabetes mellitus, hypertension, or fibroids, history and presence of obstetrical complications (hypertensive disorders of pregnancy, gestational diabetes mellitus, preterm labor, preterm premature rupture of membranes, preterm delivery, placenta previa, placental abruption, low birth weight, intrauterine fetal demise, postpartum hemorrhage, meconium staining, or chorioamnionitis), gestational age at delivery, mode of delivery, labor induction, Apgar score at 1 and 5 minutes, fetal birth weight, need for intensive care nursery, congenital malformations, neonatal complications such as intraventricular hemorrhage, necrotizing enterocolitis, respiratory distress syndrome, retinopathy of prematurity, bronchopulmonary dysplasia, ventilator support, sepsis, neonatal hospital stay and neonatal death.
