Q. 245.0( 1 Vote )

A 16-year-old boy was brought to a doctor with a complaint of non-masculine features (lack of mustache / beard / gruff voice/broadening of shoulders etc). After keen examination, the doctor found that it was a hormonal disorder and the endocrine glands responsible were not functioning properly. Mention the glands and the hormone lacking in the boy.

Answer :

The glands that are not functioning properly in the boy are testis and the hormone lacking in the body is testosterone.

Reason- It is because testis is responsible for the secretion of testosterone and this testosterone is the only hormone responsible for the all the masculine characteristics i.e. moustache, beard, gruff voice, broadening of shoulders, muscular body etc.


Since the boy is lacking all the masculine characteristics he is definitely lacking the testosterone hormone responsible for these characteristics due to non- functioning of his testis gland.
