Question

Assertion: Eunuchoidism involves aspermia (lack of sperms), underdeveloped 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 the reason is the correct explanation for assertion
(b)Both assertion and reason are correct but the reason is not the correct explanation for assertion
(c)The assertion is correct but the reason is incorrect
(d)Both assertion and reason are incorrect

Answer 1

Hint: Eunuchoidism is due to androgen deficiency antedating puberty. The hormone secreted by Leydig cells fails to support the complete development of secondary sex characters in males.

Complete answer:
-Eunuchoidism is characterized by:
Lack of adult male hair distribution
High pitched voice
Infantile genitalia
Increase of fat deposition in the pectoral, hip, thigh, and lower abdomen.

-Leydig cells release a class of hormone known as an androgen which is responsible for promoting growth and function of the male accessory sex organs like the prostate gland, seminal vesicles, Cowper’s gland, and penis. It also helps in the development of secondary sex characteristics.
-In conjunction with estrogen, progesterone causes the development of an alveolar system of the breast in eunuchoidism.

Additional Information: -Leydig cells secrete testosterone, androstenedione, and dehydroepiandrosterone under stimulation by a pituitary hormone that is luteinizing hormone.
-Leydig cells are also known as interstitial cells of Leydig present in the seminiferous tubule of the testicle.
-Progesterone is produced by adrenal glands and testes for the production of testosterone and balanced estrogen. The progesterone is known as a female hormone.

So, the correct answer is, ‘assertion is correct but the reason is incorrect.’

Note: -Male eunuchoidism is a decrease in either of the two major functions of the testes:
Sperm production
Testosterone production
-Male hypogonadism is divided into two-stage:
Stage I-Primary Hypogonadism- This occurs in tests that causes serum testosterone to decrease with an increase in LH and FSH.
Stage II-Secondary hypogonadism- This occurs in the pituitary gland or hypothalamus which causes serum testosterone to decrease with FSH and LH remaining low.
