THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Spermatozoa (sperm) are the male sex cells that carry a man’s genetic material. They are so tiny that they can’t be seen without a microscope. In a healthy man, one ejaculation usually contains between 40 million and 600 million sperm. Sperm have an oval head, a short middle, and a long tail.

Detailed explanation-2: -Male gametes in humans is called sperms. Sperms are produced by testes. Sperms fuse with egg produced by ovaries to form a zygote.

Detailed explanation-3: -Male gametes (spermatozoa) are produced by cells (spermatogonia) in the seminiferous tubules of the testes during spermatogenesis (Fig. 4.2). Spermatogonia undergo mitotic divisions to produce additional spermatogonia, which differentiate into primary spermatocytes.

Detailed explanation-4: -Male gametes are known as sperms while female gametes are known as ova or eggs. The reproductive cells are an outcome of the process of meiosis.
