The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body, and within the pelvis .
The female pelvis is lighter and thinner than the male pelvis. [11] The female inlet is larger and oval in shape, while the male sacral promontory projects further (i.e. the male inlet is more heart-shaped). [10] The sides of the male pelvis converge from the inlet to the outlet, whereas the sides of the female pelvis are wider apart. [12]
The pelvis of the human male is slightly narrower. [14] One hypothesis is that this makes it more optimized for walking and that the wider female pelvis is an evolutionary compromise between efficient walking and the need for successful childbirth. [20] This is termed the obstetrical dilemma.
The male pelvic floor also plays a role in penile health, so pelvic floor dysfunction may lead to sexual health issues like ED and discharge disorders. So basically, ...
If sperm competition results in the rival male's sperm fertilising the egg, cuckoldry could occur. This is the process whereby males unwittingly invest their resources into offspring of another male and, evolutionarily speaking, should be avoided. [33] The most researched human penis adaptations are penis size and semen displacement. [34]
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 ...
Male genital examination is a physical examination of the genital in males to detect ailments and to assess sexual development, and is normally a component of an annual physical examination. The examination includes checking the penis , scrotum , and urethral meatus . [ 1 ]
The human pelvis exhibits greater sexual dimorphism than other bones, specifically in the size and shape of the pelvic cavity, ilia, greater sciatic notches, and the sub-pubic angle. The Phenice method is commonly used to determine the sex of an unidentified human skeleton by anthropologists with 96% to 100% accuracy in some populations.
