The male external urethral orifice is the external opening of the urethra, normally located at the tip of the glans penis, [1] at its junction with the frenular delta. It presents as a vertical slit, possibly bounded on either side by two small labia-like projections, and continues longitudinally along the front aspect of the glans, which ...
The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum develops into a fetus, which is later born as an infant. The corresponding system in females is the female reproductive system.
In human anatomy, the penis (/ ˈ p iː n ɪ s /; pl.: penises or penes; from the Latin pēnis, initially "tail" [1]) is an external sex organ (intromittent organ) through which males urinate and ejaculate. Together with the testes and surrounding structures, the penis functions as part of the male reproductive system.
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. [3] [4] The penile raphe along with the skin between it are homologous to the female labia minora. [5] [6]
The two crura flank the bulb – one to each side of the bulb. Each crus is attached at the angle between the perineal membrane and ischiopubic ramus. The deep artery of the penis enters the anterior portion of the crus. Distally, each crus transitions into either corpus spongiosum of the body of the penis. [1]

The male reproductive system is a series of organs located outside the body and around the pelvis region of a male that contribute towards the reproduction process. 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 body of the penis is suspended from the pubic symphysis. [7] It has two surfaces; the dorsal and the ventral or urethral.The penile raphe runs on its ventral surface.. The body is surrounded by a bi-layered model of tunica albuginea in which a distal ligament buttresses the glans penis and plays an integral role to the penile fibroskeleton, and the structure is called "os analog", a term ...
