Abstract
Abstract
Introduction
Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in reproductive-aged women. It is reported that intrauterine exposure to hyperandrogenism may induce the development of PCOS and associated complications in later life. To analyze the intrauterine androgen levels in infants born to PCOS mothers, we evaluated the androgen levels in fetal cord blood through a meta-analysis of observational studies.
Material and methods
The following online databases were systematically searched: PubMed, EMBASE, Cochrane library databases and Web of Science up to December 2019. Human studies compared cord blood androgen levels, including testosterone (T) and androstenedione (ADION), in fetal cord blood of mothers with and without PCOS. Statistical analysis was performed in Review Manager, Version 5.3, with the inverse variance method based on a random-effects model.
Results
A total of 7 articles were scrutinized and a total of 570 samples including 268 female and 222 male infants were qualified for review. In the mass spectrograph (MS) subgroup, PCOS mothers showed no signs of increased T concentration in umbilical cord blood at birth (4 studies; hazard ratio [HR] = − 0.05; 95% confidence interval [CI] = [− 0.33,0.24]; I2 = 7%; P = 0.75; fixed-effects model). ADION level tends to be lower in daughters’ cord blood of PCOS mothers (3 studies; HR = -0.59; 95%CI = [− 1.00, − 0.19]; I2 = 0%; P = 0.004; fixed-effects model).
Conclusions
Fetal cord blood T level is not related to PCOS, while ADION levels tend to be lower in the cord blood of daughters born to mothers with PCOS.
