Abstract

To investigate the relationship of birth weight (BW) of females born at full term with functional ovarian reserve (FOR) during menacme, based on serum level of anti-Müllerian hormone (AMH), among women who were 34–35 years old. This prospective birth cohort study assessed all women who were born in Ribeirão Preto City, State of São Paulo (Brazil) between June 1, 1978 and May 31, 1979. The primary endpoint was serum AMH, a marker of FOR, and its correlation with the BW of females classified as small for gestational age (SGA), appropriate for gestational age (AGA), and large for gestational (LGA). We included 274 women in this study, 19 were SGA, 238 were AGA, and 17 were LGA. The average of AMH concentration was not significantly different (p = 0.11) among women in the SGA group (2.14 ng/mL), AGA group (2.13 ng/mL), and LGA group (2.57 ng/mL). An analysis of variance indicated that the three groups also had no significant differences in the percentage of women who had adequate AMH levels (1 ng/mL; p = 0.11). There were no significant differences in the serum concentrations of AMH among 34 and 35 year-old women who were born at full term and classified as SGA, AGA, and LGA. Our sample size allowed detection of major differences between these groups (effect size of 0.8). Association of birth weight of females born at full term with functional ovarian reserve during menacme estimated by serum concentration of anti-Müllerian hormone.

Highlights

A low functional ovarian reserve (FOR) is associated with advanced female age, a decline of natural fertility, and unsuccessful outcomes from assisted reproductive treatments (ARTs)[1]
This hypothesis predicts a lower FOR in women who were born as small for gestational age (SGA) than in those who were large for gestational age (LGA)
Among the remaining 287 women assessed for eligibility, we excluded 7 women because they were diagnosed with polycystic ovary syndrome (PCOS) in the 2007–2008 study[8], in an effort to minimize confounding

Summary

Introduction

A low functional ovarian reserve (FOR) is associated with advanced female age, a decline of natural fertility, and unsuccessful outcomes from assisted reproductive treatments (ARTs)[1]. Girls who were born SGA have a reduced ovulation rate during adolescence[7] and a higher risk of polycystic ovary syndrome (PCOS)[8] It is unknown whether the same genetic factors that lead to low BW regulate FOR. We hypothesized that an adverse intrauterine environment is reflected by low infant BW, and this can reprogram genes that regulate FOR This hypothesis predicts a lower FOR (estimated by the serum level of anti-Müllerian hormone, AMH) in women who were born as SGA than in those who were large for gestational age (LGA). We investigated the relationship of the BW of full-term females with FOR during menacme (estimated by serum AMH concentration) in women who were 34–35 years-old
