Question

Name the hormone released by testes during the onset of puberty?
A. Testosterone
B. Estrogen
C. Progesterone
D. Luteinizing hormone

Answer 1

Hint: as the hormone is released by the testes the name of the hormone should be somewhat similar to the releasing gland. The testes are heterocrine gland and it also releases sperm which fertilize with the ovum.

Complete answer:
Since the testes are part of the male reproductive organ so the hormone which they are releasing should also be complementary with the males. Now from the options, we see that the testosterone word is containing the word testes and this might be our option. But let us discuss the functions of testosterone, the primary function of this is the development of the male reproductive tissues which are generally testes and the prostate. This also helps in the promotion of secondary sexual features like growth in the girth of the body and also increases the bone mass in the body. Ince from the function we can identify that testosterone is functional in males and testes are a male body part so we can choose testosterone. Estrogen and progesterone are female reproductive hormones and this we have studied in junior classes. Estrogen is helpful in doing the primary and secondary functions in the development of the female reproductive organs. The progesterone is helpful during pregnancy which does not occur in males and is solely produced by the ovaries. The secondary sexual character in females is regulated by the ovaries also.

Note:
Though the luteinizing hormone is produced in both males and females the main difference between it and testosterone is the production place. This hormone is produced by the anterior pituitary.
