[Intrauterine programming of reproductive function--a valid concept?].
Early intrauterine fetal (mis)programming determines not only cardiovascular and metabolic regulation in later life, but also reproductive function. Intrauterine growth restriction may be associated with precocious maturation of gonadal function and an earlier onset of puberty and menarche. Especially prenatal androgen excess has negative effects on the development of the ovaries and female genital phenotype itself as well as on the neuroendocrine feedback regulation of the hypothalamic-pituitary-gonadal axis followed by a polycystic ovary syndrome with hyperandrogenism and anovulation in later life. These associations, which can be clearly demonstrated in animal experiments, need further confirmation by epidemiological and clinical trials in humans.
