The embryonic and prenatal development of the male reproductive system is the process whereby the reproductive organs grow, mature and are established. It begins with a single fertilized egg and culminates 38 weeks later with the birth of a male child. It is a part of the stages of sexual differentiation.
Male reproductive system. 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] Penile shrinkage due to low ...
The constituent cavernous cylinders of the penis. A corpus cavernosum penis (singular) (literally "porous [2] body" of the penis, pl.: corpora cavernosa) is one of a pair of sponge-like regions of erectile tissue, which contain most of the blood in the penis during an erection. [3][4][5] It is homologous to the corpus cavernosum clitoridis in ...
Vertical section of bladder, penis, and urethra. (Crus penis labeled at bottom center.) The two crura of penis (one crus on each side) constitute the root of penis along with the bulb of penis. 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.
Human reproduction is sexual reproduction that results in human fertilization to produce a human offspring. It typically involves sexual intercourse between a sexually mature human male and female. [1] During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the ovum by the sperm to ...
The bulb of penis is the proximal/posterior bulged [1] end of the (unpaired median) corpus spongiosum penis. Together with the two crura (one crus on each side of the bulb), it constitutes the root of the penis. [2] It is covered by the bulbospongiosus. Proximally/posteriorly, the bulb of penis extends towards the perineal body.
The human reproductive system usually involves internal fertilization by sexual intercourse. During this process, the male inserts their erect penis into the female 's vagina and ejaculates semen, which contains sperm. The sperm then travels through the vagina and cervix into the uterus or fallopian tubes for fertilization of the ovum.
The spongy urethra (cavernous portion of urethra, penile urethra) is the longest part of the male urethra, and is contained in the corpus spongiosum of the penis. It is about 15 cm long, and extends from the termination of the membranous portion to the external urethral orifice. Commencing below the inferior fascia of the urogenital diaphragm ...
