MICROANATOMY

Detailed explanation-1: -Men who don’t have sperm in their semen have a condition called azoospermia. It happens to about 1% of all men and 15% of infertile men. There aren’t really any symptoms that you’d notice, but if you’ve been trying to get your partner pregnant without success, this condition could be the cause.

Detailed explanation-2: -A male who has reached puberty will produce millions of sperm cells every day. Each sperm is extremely small: only 1/600 of an inch (0.05 millimeters long). Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells.

Detailed explanation-3: -Although all sperm may look the same to a casual observer in fact human ejaculates are very heterogeneous, and subpopulations of sperm with distinct biochemical and physiological characteristics can be identified in every sample.
