What are Human Reproduction?
The Male Reproductive System
It consists of the primary sex organs (a pair of testes):
These glands secrete seminal plasma rich in fructose, calcium and certain enzymes. Secretions of bulbourethral glands also help in lubrication of penis.
The Female Reproductive System
It consists of the primary sex organ that is a pair of ovaries.
The process of formation of gametes is called gametogenesis. It is of two types:
Spermatogenesis in males
The process of formation of sperms in males is called spermatogenesis
Oogenesis in females
The process of formation of a mature female gamete is called oogenesis
Structure of sperm composed of head, neck, middle piece and a tail.
The cyclic changes that occur in the reproductive organs of primate females is called menstrual cycle
The events in a menstrual cycle can be studied under four phases:
The process of fusion of a sperm with an ovum is called fertilization.
