Human Reproduction ( Male Reproductive System)
Human reproduction system is formed by gametes i.e., sperms in males and ovum in females and the transfer of sperms into the female genital tract. This fusion of male and female gametes leads to form a zygote. The reproductive events occurred in male and female are different.
Male reproductive system:
The male reproductive system is located in the pelvis region. It consists of pair of testes along with accessory ducts, glands, and external genitalia
The testes are situated outside the abdominal cavity within a pouch called scrotum. The scrotum helps in maintaining the low temperature of testes necessary for spermatogenesis. The testes are covered by a dense covering. Each testis has about 250compartments called testicular lobules in which sperms are produced. each seminiferous tubules in which sperms Lined on its inside by two types of cells called male germ cells and sertoli cells.
The male germ cells undergo meiotic divisions finally leading to sperm formation, while Sertoli cells provide nutrition to the germ cells. The male sex accessory ducts include rete testis, vasa efferentia through rete testis
The penis is the male external genitalia and its made up of special tissue that helps in the erection of the penis to facilitate insemination. The enlarged end of the penis called the glans penis is covered by a loose fold of skin called foreskin.
