Solution

The correct option is C Testosterone and estrogen
Thyroxine is secreted from thyroid gland. It stimulates the consumption of oxygen by metabolically active tissues and also increases the oxidation of glucose in tissues.
Follicle stimulating hormone (FSH) is secreted from the anterior part of pituitary gland. It stimulates the growth of ovarian follicles in females.
Luteinizing hormone or LH is secreted from anterior lobe of pituitary gland and stimulates growth of ovarian follicles in females.
GH (Growth hormone) is secreted from anterior lobe of pituitary gland and stimulates body growth and carbohydrate, protein, fat metabolism.
Testosterone is the male sex hormone secreted from Leydig cells in testis and stimulates the development of secondary sexual characters in males.
Estrogen is the female sex hormone secreted from ovarian follicles and stimulate the development of secondary sexual characters in females.
So, the correct answer is 'Testosterone and estrogen'.

Q. Testosterone is a steroid hormone produced by all vertebrate animals and, in humans and other mammals, it is secreted in large amounts by the testes of males and to a much lesser extent, the ovaries of females. In adult males, testosterone plays a key role in the development of reproductive organs and it promotes the secondary sexual characteristics of body and facial hair, increased muscle and bone mass, and a deep voice. Testosterone, like all hormones, works via long distance signaling and is regulated by other hormones as illustrated below:

Figure 1:

Testosterone regulation by cooperation between the hypothalamus, pituitary, and testicular endocrine glands. The major regulatory hormones involved are luteinizing hormone (LH), follicle-stimulating hormone (FSH) and gonadotropin-releasing hormone (GnRH).

When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH. FSH and LH then stimulate the testis to produce testosterone.
How is homeostasis achieved when testosterone levels begin to rise?

Q. Refer the following features.
I. Adenohypophysis produces gonadotropins.
II. Besides Sex cells, hormones are also produced by testis and ovary.
III. Testosterone is produced by Leydig's cells.
IV. Oestrogen is produced by the ovary.
Which of the above factors influence secondary sexual characters?

Q. Secondary sexual characters in men are controlled by _____ hormone.

_____ is the secondary messenger utilized by ACTH, FSH, LH and calcitonin hormones.

Q. Assertion :The ovarian cycle in follicles is the control of the gonadotropic hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH). Reason: During ovarian cycle, follicles undergo maturation, contains a secondary oocyte and produce female sex hormone.
