What is the Origin of Sexual Response Cycle?

This term originates from the seminal work of sexologists Masters and Johnson in the mid-20th century, who systematically mapped the observable physiological responses during sexual activity, establishing a standardized clinical framework.

What is the Mechanism of Sexual Response Cycle?

This cycle is a complex neuroendocrine event driven by the integration of central nervous system signals and peripheral vascular and muscular responses. Hormones like testosterone and estrogen modulate libido and tissue sensitivity, while neuropeptides and neurotransmitters coordinate the autonomic shifts necessary for vascular engorgement, muscle tension, and the final reflexive stages of orgasm and resolution.
