Sexual Receptor Density

Meaning

Sexual Receptor Density refers to the concentration of specific hormone receptors, primarily those for androgens and estrogens, on the cells of target tissues involved in sexual function and desire. A high density of these receptors, particularly in the brain’s limbic system and peripheral reproductive tissues, translates to enhanced sensitivity and responsiveness to circulating sex hormones. Maintaining optimal density is a crucial physiological determinant of robust libido, sexual arousal, and tissue health.
