Sperm are produced, stored, and delivered by the male reproductive system. The terminal phase of spermatogenesis is called spermiogenesis and consists of the differentiation of the newly formed spermatids into.

At the end of the glans is a small slit or opening, which is where semen and urine exit the body through the urethra yoo-REE-thruh. It is located inferior to the penis in the pubic region. This fertilized egg is now called a zygote and contains 46 chromosomes — half from the egg and half from the sperm. They originate in the 4th week of foetal development in the endodermal walls of the yolk sac and migrate to the primordium of the testis, where they differentiate into spermatogonia. J Anat ;

They move through the vas deferens and mix with secretions from the seminal vesicle and bulbourethral gland to form the semen. Spermatogenesis is regulated by follicle stimulating hormone FSH , which in males stimulates the spermatogenic epithelium, and luteinizing-hormone LH , which in males stimulates testosterone production by Leydig cells in the interstitial tissue. If this sperm meets with an egg, it can cause trisomy, a zygote that has three copies of a particular chromosome. The terminal segment of the ductus epididymidis is the site of storage of the mature spermatozoa. In addition to its reproductive function, the penis also allows for the excretion of urine through the urethra to the exterior of the body. The system itself is divided into two distinct units:. From the testicles the spermatozoa move to the epididymis.

When selecting geese for breeding, the sex of each goose must be determined. These tubes deliver the male gametes from their site of production in the testes to their destination outside the body. Figure 15 shows the male and female reproductive organs of goslings much enlarged. The glands are embedded into a fibromuscular stroma, which mainly consists of smooth muscle separated by strands of connective tissue rich in collagenous and elastic fibres. This happens without a guy ever having to think about it.
