What does the pelvis do?
The National Cancer Institute (NCI) dictionary describes the pelvis as the bones between the lower abdomen and upper thighs that connect the spine to the legs. It says the pelvis supports upper body weight, aids balance and walking, and protects the bladder, reproductive organs, colon, and rectum.
The pelvic region and its organs
NCI adds that the word can also describe the pelvic region, the area of the body below the abdomen that contains the hip bones, bladder, and rectum. In females it also contains the vagina, cervix, uterus, fallopian tubes, and ovaries. In males it also contains the prostate and seminal vesicles.
Pelvic pain
MedlinePlus says pelvic pain occurs mostly in the lower abdomen area and can be a sign of a problem with one of the organs in the pelvic area. In men the cause could be a problem with the prostate. In men and women it could be a symptom of infection, or a problem with the urinary tract, lower intestines, rectum, muscle, or bone.

Pelvis in Spanish
- Spanish term
- Pelvis
- Gender and article
- feminine: la pelvis
- Pronunciation
- PEHL-vees
Pelvis is spelled the same in Spanish and in English. The Real Academia Española dictionary marks it as a feminine noun, so it is la pelvis, and defines it as the region of the body formed by the sacrum, the coccyx and the innominate bone (sacro, coxis, innominado). The same dictionary gives a second anatomical sense: a funnel-shaped cavity located in each kidney that continues into the ureter. It lists cadera and bacinete as synonyms or related words.
The National Cancer Institute's Spanish dictionary says the term sometimes also describes the región pélvica, the area below the abdomen that contains the hip bones (huesos ilíacos de la cadera), the bladder (vejiga) and the rectum (recto). The adjective in MedlinePlus en español is pélvico or pélvica: pelvic pain is dolor pélvico, described there as occurring mainly in la parte baja del abdomen. Its encyclopedia article on the pelvis x-ray is titled Radiografía de la pelvis.
