Androgen receptors (ARs) are nuclear transcription factors that mediate the biological effects of testosterone and dihydrotestosterone (DHT). These receptors are expressed in multiple tissues, including the testes, prostate, skeletal muscle, bone, and central nervous system.
Upon binding to androgens, ARs translocate to the nucleus, where they regulate gene expression involved in spermatogenesis, secondary sexual characteristics, erythropoiesis, and metabolic regulation. Mutations or dysfunction in androgen receptor signaling may lead to disorders such as androgen insensitivity syndrome.
Clinically, impaired androgen receptor activity can manifest as infertility, reduced virilization, decreased libido, and metabolic disturbances. Therapeutic interventions often focus on optimizing hormonal levels, but receptor-level abnormalities may require specialized management.
Understanding androgen receptor dynamics is essential in advanced andrological research and clinical erotic practice.
