Question

Assertion: Eunuchoidism involves aspermia (lack of sperms), under developed sex organs and lack of accessory sex characters in males.
Reason: Failure of progesterone secretion leads to eunuchoidism.

A. Both assertion and reason are correct and reason is correct explanation for assertion
B. Both assertion and reason are correct but reason is not the correct explanation for assertion

D. Both assertion and reason are correct

Answer 1

Hint: The secondary sexual characters develop at the puberty. The testosterone is the male sex hormone which helps in the secretion of male gametes. The sperms are produced in the seminiferous tubule. Deficiency of sexual development can cause eunuch state in males.

Complete answer:
-At puberty various changes in the body occur. These changes include sexual development. In males, these changes include enlargement of the scrotum and testes, pubic hairs grow, and other secondary sex characteristics.
-The condition caused by the deficiency of sexual development at puberty in males is called Eunuchoidism. The lack of fully developed reproductive organs and increase in female sex characters cause eunuch condition in males. It can be caused by the lack of sex hormone that is testosterone. The testosterone is the male sex hormone produced from the testes. Its secretion is controlled by hypothalamus and pituitary.
-From the above information we have found that failure of progesterone secretion does not lead to eunuchoidism.

Hence, the correct answer is option (C).

Note: In some males, high voice or lack of facial and body hair occur due to absence of normal production of male sex hormones. The male reproductive system also includes other hormones such as leydig hormone which helps in the nourishment of sperms. The glandular secretion in male reproductive system helps in the development and ejaculation of sperms.
