PATHOLOGY

Detailed explanation-1: -Men aren’t born with ready-made sperm cells-they have to be made later, from puberty onwards. (Interestingly, when females are born they already have all their quota of eggs.) Spermatozoa are made in vessels, within the testicles, called seminiferous tubules.

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: -It’s been long established that sperm from different males vary in their characteristics because of the genetic differences between the males. This study established that different sperm from the same male vary in their characteristics because they differ in their genetic cargo.
