The same human pelvis, front imaged by X-ray (top), magnetic resonance imaging (middle), and 3-dimensional computed tomography (bottom). The pelvis (pl.: pelves or pelvises) is the lower part of an anatomical trunk, [1] between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton [2] (sometimes also called bony pelvis or pelvic skeleton).
A.—Diagram of the primitive urogenital organs, from 'Diagrams to show the development of male and female generative organs from a common type' * w, w. Right and left Wolffian ducts. The observable, visual differences become apparent between male or the female reproductive organs are not seen initially.

Tail end of human embryo, from eight and a half to nine weeks old. 1 - 7: Homologous male and female pelvic organs. Diagrams that show the development of male and female organs from a common precursor.
The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet (the superior opening of the pelvis). Its lower boundary is the pelvic floor. The pelvic cavity primarily contains the reproductive organs, urinary bladder, distal ureters, proximal urethra, terminal sigmoid colon, rectum, and ...
The pelvis and legs contain, from superior to inferior, the inguinal or groin region between the thigh and the abdomen, the pubic region surrounding the genitals, the femoral region encompassing the thighs, the patellar region encompassing the front of the knee, the crural region encompassing the lower leg, between the knee and ankle,
This means that in the event of a rival male's sperm occupying the reproductive tract of a female, the human penis is able to displace the rival sperm, replacing it with his own. [42] Semen displacement has two main benefits for a male. Firstly, by displacing a rival male's sperm, the risk of the rival sperm fertilising the egg is reduced. [43]
Left and right inguinal regions shown in lower part of diagram. In human anatomy, the groin, also known as the inguinal region or iliac region, [1] is the junctional area between the torso and the thigh. [2] The groin is at the front of the body on either side of the pubic tubercle, where the lower part of the abdominal wall meets the thigh.
