Androgen receptor (AR) is expressed by testicular somatic cells including steroidogenic Leydig cells (LC). Its role in LC is ill defined, with hypotheses based on evidence from total androgen receptor knockout models implying that LC AR is responsible for final LC number, regulation of steroidogenic enzyme expression and LC maturation.To better define the role of AR in LC, we generated a mouse line with a LC specific ablation of AR (LCARKO) using the Cre...

Introduction: Androgen receptors (AR) have been detected in the human endometrium throughout the menstrual cycle and are reported to regulate expression of genes associated with cellular proliferation and cell-cycle regulation. Endometriosis is defined by establishment and growth of endometrial tissue in ectopic locations (typically on the peritoneal wall); patients often experience pain and infertility. In the current study we have used human tissue and a new mouse model of e...
