How many chromosomes are present in a single Spermatogonium?
Are the 4 sperm cells produced during spermatogenesis genetically identical?
Spermatogenesis occurs only in human males (in the testes), not in females. It is the process by which spermatids are formed via meiosis. The process of meiosis contributes to genetic diversity. This is why siblings are not identical to each other or to their parents.
Is there liquid in your balls?
What is a hydrocele? A hydrocele is a collection of fluid in a sac in your scrotum next to a testicle (testis). It usually occurs on one side but sometimes a hydrocele forms over both testicles (testes). The normal testis is surrounded by a smooth protective tissue sac.
Can your ball go inside you?
When the cremaster muscle contracts, it pulls the testicle up into groin. This response is normal in males. Cold temperature and anxiety are two factors that trigger what is known as the cremasteric reflex, or the pulling of the testicles upward toward the groin.
What is inside a males sack?
The scrotum (or scrotal sac) is a part of the external male genitalia located behind and underneath the penis. It is the small, muscular sac that contains and protects the testicles, blood vessels, and part of the spermatic cord.
Why is there a line down my balls?
It’s called the Scrotal Raphe and is a “scar” that is from our time in the womb. It’s formed during the development of the genitals, called the Urogenital Folds and is the resulting line you see. In certain cases, an infant will be born with genitalia that is ambiguous.
What is the purpose of balls on a man?
Testicles (testes) The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
