Question
Which of the following statements is true concerning hormonal control over the male reproductive system?Multiple ChoiceThe hypothalamus secretes a hormone called gonadotropin-releasing hormone.Follicle-stimulating hormone and luteinizing hormone are present in both males and females.These hormones are involved in a negative feedback relationship.The interstitial cells produce testosterone.All of the answer choices are true concerning hormonal control over the male reproductive system.
Solution
All of the answer choices are true concerning hormonal control over the male reproductive system.
Here's why:
-
The hypothalamus does secrete a hormone called gonadotropin-releasing hormone (GnRH). This hormone signals the pituitary gland to produce and release follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
-
Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are indeed present in both males and females. In males, these hormones are crucial for sperm production and testosterone synthesis.
-
These hormones are involved in a negative feedback relationship. When levels of testosterone are high, the hypothalamus and pituitary gland receive feedback to reduce the production of GnRH, FSH, and LH. This helps to maintain a balanced level of hormones.
-
The interstitial cells (also known as Leydig cells) in the testes do produce testosterone, the primary male sex hormone. This hormone is responsible for the development of male secondary sexual characteristics.
So, all of the statements are true concerning hormonal control over the male reproductive system.
