Research on the mechanisms and factors influencing female orgasm, including anatomical, neurobiological, hormonal, and psychosocial aspects.
Laboratory studies define the female orgasm using a range of physiological markers—vaginal blood flow/engorgement, pelvic and uterine muscle contractions, and neuroendocrine changes such as prolactin ...
Labor-based evidence directly comparing time-to-orgasm for oral sex (cunnilingus) versus manual clitoral stimulation is scarce; most empirical data are large surveys, laboratory masturbation protocols...
Experimental and clinical literature shows a mix of event‑level, couple‑focused interventions tested to increase women’s orgasm likelihood: explicit emphasis on sufficient and partner pursuit of femal...
Functional imaging shows both shared “orgasm” circuitry (reward, limbic, brainstem and cerebellar regions) and stimulation‑specific differences mapped in the somatosensory cortex: direct clitoral, vag...
Anatomical measurements such as anterior vaginal wall thickness (often measured as distance to the pubic bone or “urethrovaginal” space) and vaginal girth correlate with patterns of neural innervation...
