GENERAL HISTOLOGY

Detailed explanation-1: -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. Sex cells are different from other cells in one special way: Put simply, they only have one half of the total amount of human genetic information.

Detailed explanation-2: -A gamete is a reproductive cell of an animal or plant. In animals, female gametes are called ova or egg cells, and male gametes are called sperm. Ova and sperm are haploid cells, with each cell carrying only one copy of each chromosome. During fertilization, a sperm and ovum unite to form a new diploid organism.

Detailed explanation-3: -While other normal human cells have 46 chromosomes (or 23 pair), gametes contain 23 chromosomes. Chromosomes are long threadlike structures found in a cell nucleus that contain genetic material known as deoxyribonucleic acid (DNA).

Detailed explanation-4: -In the human reproductive process, two kinds of sex cells, or gametes (pronounced: 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 (pronounced: ZYE-goat).

Detailed explanation-5: -The head of the sperm cell contains the male’s genetic information that is to be passed on to the next generation. Normally, the head of a sperm cell contains one copy of each chromosome . In men with macrozoospermia, the sperm cell head contains extra chromosomes, usually four copies of each instead of the usual one.
