Question

How many sperms are produced from one primary spermatocyte?
A. 8
B. 6
C. 2
D. 4

Answer 1

Sperms, which is male gametes, are responsible for the sexual reproduction in animals including human beings. Sperms are produced in the testes and the process by which they produce is known as spermatogenesis.

Complete Answer:
- Sperm is the male gametes which is a haploid cell and produced by the process known as spermatogenesis. Spermatogenesis is the process by which the primary male sperm cell undergoes meiosis to form spermatogonia which further develops into primary spermatocytes.
- Now these spermatocytes divide into secondary spermatocytes and these secondary spermatocytes develop into two spermatids also, known as spermatozoa. After the maturation of these spermatozoa, sperm cells are produced.
- Maturation of the sperm cells take place under the influence of male hormone, that is testosterone which is responsible for the removal of unwanted organelles and cytoplasm components. These extra materials are digested by the Sertoli cells present in the testes.
- Rate of spermatogenesis can be affected by many factors like dietary deficiencies, abnormalities in the hormonal levels, UV or X-rays exposure, alcohol consumption, and infections. Proper intake of vitamin B, E and A can help in normal functioning and formation of the sperm cells in the body.

Thus, we can say that option ‘D’ is the correct option.

Note: Spermatogenesis process is very sensitive to the changes in the temperature and hormone regulation. Spermatogenesis cannot take place even at normal body temperature thus, testes are situated outside the abdominal cavity and present in the scrotum. It requires $20^\circ$ C lower temperature then body normal temperature.
