During ejaculation, sperm are propelled from the epididymis along a duct called the vas deferens (the coat hanger-shaped duct shown in the 3D image above).

The male reproductive system consists of external organs. The testes in the scrotum produce the male gamete, sperm, which is ejaculated in seminal fluid by the penis. The female reproductive system primarily consists of internal organs.

Ejaculation: how it works. When a man is sexually stimulated, friction on the glans penis and other stimuli send signals through the nervous system that result in ejaculation. At the moment of ejaculation the walls of the epididymis contract (squeeze) to create peristaltic waves that push sperm into the vas deferens.

A spermatocele (epididymal cyst) is a painless, fluid-filled cyst in the long, tightly coiled tube that lies above and behind each testicle (epididymis). The fluid in the cyst may contain sperm that are no longer alive.

Conception is the time when sperm travels up through the vagina, into the uterus, and fertilizes an egg found in the fallopian tube. Conception — and ultimately, pregnancy — can involve a surprisingly complicated series of steps. Everything must fall into place for a pregnancy to be carried to term.

Key Points The testes in the scrotum produce the male gamete, sperm, which is ejaculated in seminal fluid by the penis. The female reproductive system primarily consists of internal organs. The female gamete, ovum, is produced in the ovaries and is released monthly to travel to the uterus via the Fallopian tubes.

In artificial insemination, a doctor inserts sperm directly into a woman's cervix, fallopian tubes, or uterus. The most common method is called "intrauterine insemination (IUI)," when a doctor places the sperm in the uterus.

A sperm sample collected in a sterile container at body temperature may remain alive for several hours, but the sperms' fertilizing capability drops dramatically within 60 minutes after ejaculation. Sperm that moves from the vagina into the uterus can survive longer.

Sperm leaves the epididymis by way of the vas deferens (this is the tube that is divided during a vasectomy) which travels to join the seminal vesicles and prostate. Sperm mixes with fluid from the seminal vesicles and prostate to produce semen, the fluid that comes out from the penis at the time of ejaculation.

Sperm gain motility in the epididymis. Capacitation is the process by which spermatozoa become motile and are fully mature; this does not occur until they are in the female reproductive tract.

In ICSI, one sperm is directly injected into the egg. It is important you do not confuse these treatments with Intra-Uterine Insemination (IUI); the process whereby a sperm is inserted into a woman's womb at the most fertile point in her menstrual cycle.

Each ejaculatory duct is about two centimeters in length and is created when the seminal vesicle's duct merges with the vas deferens. At this point, these ducts travel through the prostate and, at its far end, drain into the colliculus seminalis's urethra.

The epididymis consists of three parts: head, body, and tail. The head of the epididymis is located on superior pole of testis. It stores sperm for maturation. The body of the epididymis is a highly convoluted duct which connects the head to the tail of the epididymis.

Sperm cells form during the process known as spermatogenesis, which in amniotes (reptiles and mammals) takes place in the seminiferous tubules of the testes. ... The spermatids then mature and, in animals, construct a tail, or flagellum, which gives rise to the mature, motile sperm cell.

First, sperm cells are produced in the small seminiferous tubules of the testicles. These oval shaped glands are protected by a sac called the scrotum. After the sperm cells are produced, they are stored in a large coiled tube on the outer surface of each testicle called the epididymis.
