Sexual reproduction helps to maintain the continuity of Life on the earth and it helps in the increase of immunity to the new generation offspring’s. The sexual reproduction in the human beings is done through the sexual reproductive organs. They sexual organs secrete substances called spermatozoa and ovum. this article focuses on analyzing the differences between spermatozoa and ovum.


Human male reproductive system consists of a pair of testis. Testis produces millions of Spermatozoa during copulation. Sperms are ejaculated through urethra. once after ejaculated, the sperms have a life expectancy of about 48 hours within the female reproductive tract. Sperm is composed of three parts they are head, mid peace, tail. The process of production of spermatozoa is called as spermatogenesis.


Female reproductive System of human beings consists of a pair of ovaries present in the abdominal region. Ovaries produce ‘Ova’ The female gametes. The formation of ‘Ova’ in the ovary is called as Oogenesis. The ‘ova’ are developed follicles of ovaries and the development and production of ‘ova’ is called as Ovulation. if the Ovum is paired with sperm then fertilization occurs in the female reproductive system.


Spermatozoa are formed in the male reproductive system. Ovum is produced in the female reproductive system.
Each spermatozoa has head, neck, middle piece and tail. The ovum is round in shape.
Spermatozoa are produced in millions in number. Ova are produced only one or two every month.
The spermatozoa are motile; they have the capacity to move after entering into the female reproductive system. The ovum are non-motile, they are unable to move.
Production of sperm starts only after the puberty in males. Production of Ovum may start after birth, but ova Will be matured after puberty.
The process of production of spermatozoa is called as spermatogenesis. The process of formation of Ova please called as Oogenesis.
The lifespan of sperm says about 24 to 72 hours. The lifespan of Ovum is only 25 hours.
The testis produces sperm in males. The ovaries produce Ovum in females.


From the above discussion, we can conclude that both male and female reproductive systems have different structures and functioning. The sperm and Ovum plays an important role in fertilization.
