In seminiferous tubules, repeated division of the germinal epithelium produces?
Correct answer: B. Spermatogonia
- A. Oogonia
- B. Spermatogonia
- C. Ovogonia
- D. Ovum
Explanation
In the seminiferous tubules of the testes, the repeated division of the germinal epithelium (the cells that give rise to sperm) through a process called spermatogenesis produces sperm cells, also known as spermatozoa. Spermatogenesis is the complex and continuous process by which male germ cells, called spermatogonia, undergo mitotic divisions, meiotic divisions, and maturation to eventually become mature sperm cells. These sperm cells are then released into the lumen of the seminiferous tubules and subsequently travel through the male reproductive system.

About Reproduction
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
