Pronunciation: /ˈpɛlvɪk ˈkævəti/ (“PELL-vik KAV-uh-tee”)

Connection to sexuality
Yes. The pelvic cavity contains sexual and reproductive organs (uterus, vagina, ovaries, prostate, seminal vesicles), making it central to fertility, arousal, and sexual health. Disorders of the pelvic cavity—such as endometriosis, pelvic inflammatory disease, or prostate enlargement—can impact sexual pleasure, comfort, and function. The health of the pelvic cavity is therefore closely tied to sexual well-being and reproductive capacity.
