Introduction: Neonatal events may contribute to the development of disorders such as type 2 diabetes and obesity at adult age. We have previously shown that neonatal testosterone (T) programming of female rats is followed by insulin resistance and changes in adipose tissue distribution with centralization of body fat. Therefore, the aim of this study was to examine the effects of neonatal injection of T, estradiol (E) or dihydrotestosterone (DHT) on insulin sensitivity and siz...

Continuous administration of dihydrotestosterone or letrozole to immature female rats results in polycystic ovary syndrome characteristics at adult age

Introduction: Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorder associated with ovulatory dysfunction, hyperandrogenism, abdominal obesity and insulin resistance. Since hyperandrogenism is a PCOS key feature, the aim was to evaluate the effects of androgen receptor activation in terms of continuously administration, beginning pre-pubertal, of either the non-aromatizable androgen dihydrotestosterone (DHT) or the aromatase inhibitor letrozole (L), on...
