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.
Male felids are able to urinate backwards by curving the tip of the glans penis backward. [54] [55] In cats, the glans penis is covered with spines. Penile spines also occur on the glans of male and female spotted hyenas. [54] In male dogs the glans penis is smooth and consists of two parts called the bulbus glandis and pars longa glandis. [56]
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]
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 ...
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 ...
As part of the glans penis, the frenulum is innervated by divisions of the pudendal nerve; the dorsal nerve of the penis and a branch of the perineal nerve. [ 10 ] [ 11 ] Blood supply to the frenulum is provided by branches of the dorsal artery of the penis that curve around each side of the neck to enter the frenulum and the glans from its ...
“That said, for people that use their penis for sexual pleasure, having an adequate testosterone level helps to improve the function of the penis.” Before your next romp, try some testosterone ...
The glans (/ ɡ l æ n z /, [1] [2] pl.: glandes / ˈ ɡ l æ n d iː z /; from the Latin word for "acorn") [3] is a vascular structure located at the tip of the penis in male mammals or a homologous genital structure of the clitoris in female mammals.
