Which endocrine gland secretes sex hormones?
Correct answer: B. Testis
- A. Adrenal medulla
- B. Testis
- C. Hypothalamus
- D. Pituitary
Explanation
The testes are the male gonads responsible for producing testosterone, the primary male sex hormone.The testes consist of many coiled seminiferous tubules where the spermatozoa develop and, between the tubules, regions of interstitial cells produce gonadal hormones called testosterone and 17 b-hydroxytestosterone.After the initiation of development, the sex organs in the foetus produce them, and their level rises fairly consistently until puberty. After puberty the supply of LH (ICSH), and therefore, the level of testosterone, remains constant. In the foetus, it initiates the development of the sex organs. At puberty it brings about development of the male secondary characteristics and promotes the sex drive.
