Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to determine maternal androgen metabolism during pregnancy and the impact of androgen disorders on mothers and infants.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Women with polycystic ovary syndrome (PCOS) have an impaired fertility and significant higher complication rates during infertility treatment, pregnancy and the perinatal period. Complications include the occurrence of multiple gestations, ovarian hyper stimulation syndrome, early pregnancy loss, gestational diabetes, pregnancy-induced hypertension, pre-eclampsia and need for caesarean section. Moreover, their infants are more frequently born preterm, have higher perinatal mortality rates and are more often admitted to a neonatal intensive care unit. The etiology of PCOS is not particularly mapped, but a genetic background can be assumed by analyzing PCOS families. In utero androgen excess has also been suspected to be an important risk factor. Animal studies have demonstrated that intrauterine hyperandrogenic environment affects the offspring by leading to biochemical and morphological features of PCOS. Sex differences in prenatal androgen levels have been observed and testosterone levels in umbilical cord blood and in amniotic fluid are higher in healthy male babies than in healthy female babies. There are just a few reporting on the relation between maternal androgen levels during pregnancy and the respective offspring. The aim of this clinical study is to determine maternal androgen metabolism and the impact of androgen disorders on mothers and infants.
