Chromosomal abnormalities can occur during fertilization impacting the development of the male reproductive system. The genotype of the male consists of a Y chromosome paired with an X chromosome. Female sex is determined by the absence of a Y chromosome. Some individuals are male who have the XX male syndrome and androgen insensitivity ...
Each crus represents the tapering, posterior fourth of each corpora cavernosa penis; the two corpora cavernosa are situated alongside each other along the length of the body of penis while the two crura diverge laterally in the root of penis before attaching firmly onto either ischial ramus at their proximal end.

The penile raphe is part of a broader line in the male reproductive organs, that runs from the anus through the perineum (perineal raphe) and continues to the scrotum and penis, collectively referred to as median raphe.

The primary direct function of the male reproductive system is to provide the male sperm for fertilization of the ovum. [3] The major reproductive organs of the male can be grouped ...
The corona and the neck are highly vascularized areas of the penis. The axial and dorsal penile arteries merge together at the neck before entering the glans. [8] Branches of the dorsal artery of the penis curve around the distal shaft to enter the frenulum and the glans from its ventral surface. [9]
