GENERAL HISTOLOGY

Detailed explanation-1: -The formation of sex cells is a central part of human reproduction: In fertilization, an egg cell and a sperm cell combine. These sex cells are also called reproductive cells or gametes. Sperm cells are produced in men’s testicles and egg cells are produced in women’s ovaries.

Detailed explanation-2: -In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).

Detailed explanation-3: -Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.

Detailed explanation-4: -Sperm are produced in the seminiferous tubules inside the testes.

Detailed explanation-5: -Primary cell types in testes are germ cells, Sertoli cells which secrete inhibin, Leydig cells which produce and secrete androgens, peritubular hyoid cells, macrophages and epithelial cells. Germ cells line the lumen of seminiferous tubules and develop into sperm cells.
