The mammalian testis has two major functions, sperm production, and synthesis of androgens. The maintenance and regulation of those two functions are under the control of endocrine and paracrine factors, but are also related to lipid homeostasis, including cholesterol. The nuclear oxysterol receptors (LXRs) are transcription factors belonging to the superfamily of nuclear receptors. The LXRs are expressed in the male genital tract and testis, and their ligands are active at physiological concentrations. In these organs, these receptors regulate cholesterol homeostasis, a precursor essential for the synthesis of testicular steroids. They also control the different steps of steroidogenesis by regulating the enzymes of steroidogenesis. In the ...
