Question

The sex hormones, ____ and estrogen are responsible for the development of _____ characters
(a) Progesterone, secondary sex
(b) Secondary sex, testosterone
(c) Insulin primary sex
(d) None of the above

Answer 1

Sex or reproductive hormones have multiple functions in both males and females. They are responsible for the growth of the secondary sex characteristics during puberty. Later during adulthood, they are in charge of regulating the reproductive cycle.In females, sex hormones releases from the ovary, regulate the menstrual cyccle, and control endometrial growth.

Complete answer:
- Progesterone: A female hormone, the principal hormone that prepares the uterus to receive and sustain fertilized eggs.The sex hormones, progesterone and estrogen are responsible for the development of secondary sexual characters.It is primarily emitted by the corpus leteum. The primary distinction among estrogen and progesterone is that estrogen controls the arrangement and support of optional female sex qualities while progesterone controls the development and maintenance of endometrium of the uterus.
- Secondary sex, testosterone: A steroid hormone that is the most potent naturally occurring androgen and that regulates the development of the male reproductive system and male secondary sex characteristics.
Testosterone is the essential sex hormone and anabolic steroid in guys. In male people, testosterone assumes a key function in the advancement of male regenerative tissues, for example, testicles and prostate, just as advancing auxiliary sexual attributes, for example, expanded muscle and bone mass, and the development of body hair.So this is an incorrect option.
- Effects of Insulin In addition to insulin's effect on entry of glucose into cells, it also stimulates the uptake of amino acids, again promoting its overall anabolic effect. When insulin levels are slightly low, as in the fasting state, the balance is pushed toward intracellular protein degradation.So this is an incorrect option.
Hence option ‘(a) Progesterone, secondary sex’ is the correct answer.

Note: The ovaries and placenta are the organs responsible for the secretion of progesterone during pregnancy. Although it may be released by the adrenal glands and the liver as well.As in the case of estradiol, progesterone production starts during puberty, and begins dropping in menopausal women. It has an important role in the development of the secondary sex characteristics to some extent.
