Question

AdenohypophyseaI hormone, that stimulates the gonads in males and females are called as
A. Prolactin
B. Luteotropic hormone
C. Follicle-stimulating hormone
D. Gonadotropins

Answer 1

Hint: The anterior lobe of the pituitary gland also known as the adenohypophyseal gland is a portion of the pituitary gland which is responsible for the production of several important hormones. The anterior pituitary regulates several physiological processes including stress, growth, reproduction and lactation.

Complete step by step answer:
The pituitary gland is a major organ of the endocrine system. The entire pituitary gland is also called the master gland as it controls all endocrine hormone secretion and regulation. The pituitary gland can be divided into the anterior pituitary and the posterior pituitary.

The anterior pituitary secretes five types of endocrine hormones which are the growth hormone(GH) also known as somatotropins, Prolactin (PRL) or also known as Lactotropins, (Luteinizing hormone (LH) and Follicle-stimulating hormone (FSH) which are known as gonadotropins, Adrenocorticotropic hormone (ACTH) also known as corticotropins and Thyroid-stimulating hormone (TSH) or also known as thyrotropin (TSH). Hormones secreted by the anterior pituitary are called trophic hormones which denote that these hormones directly affect the growth of the cells either as hyperplasia or hypertrophy on the tissue it is stimulating. Tropic hormones are named for their ability to act directly on target tissues or other endocrine glands to release hormones, causing numerous cascading physiological responses.
Therefore, the correct answer is option D.

Note: Adenohypophysis hormones refer to all hormones secreted by the anterior pituitary. As the hormone is called tropic hormones, the LH and FSH both play a role in the gonadal development and together are known as the gonadotropins. In men, these hormones cause the testicles to make testosterone. In women, they cause the ovaries to make estrogen and progesterone.
