Question

What are male germ cells?

Answer 1

Hint: A germ cell is a sex cells or gametes of an organism that produce during sexual reproduction that passes gene from one generation to next generation. Germ cells are Egg and sperm cells in female and male respectively.

Complete answer:
Male germ cells are referred to as Spermatocytes. These cells are found in Male reproductive organ in coiled masses of seminiferous tubules in testis. Seminiferous tubules contain two types of germ cells : Spermatogonia and Sertoli cells.
Spermatogenesis is a process by which Spermatogonia or spermatocytes are formed. Sertoli cells are responsible for providing nutrition to the sperm cells. Some of the cells do not proliferate and undergo cell division (mitosis) to form primary spermatocytes. Further mitosis cell division secondary spermatocytes are formed as spermatids, that is haploid. After nuclear condensation of spermatid form Sperm. Sperm is a mature male Germ cell.
The structure of sperm is composed of Head, neck, middle piece and tail. Its body is enclosed by plasma membranes. The head region contains an elongated haploid nucleus of dense genetic material (23 chromosomes). Middle piece of sperm contains Mitochondria, it is the cell organelle that produces energy. The anterior portion appears as a cap-like structure called acrosome. This acrosome is filled with enzymes that help in the fertilization of the ovum. The tail of the sperm is referred to as flagella. It moves like a propeller, around and around.

Note:
Male infertility is a disorder in male due to low sperm production or abnormal sperm function or blockage that prevent the release of sperm. In some cases, infertility in men causes genetic disorders like cystic fibrosis gene mutation, chromosomal abnormalities, Klinefelter’s syndrome, Y chromosome microdeletions of genes, and chromosomal translocations.
