17 Questions
What is the main function of gonadotropic hormones LH and FSH in the male reproductive system?
Activate spermatogenesis in Sertoli cells
How does testosterone regulate its own secretion in the male reproductive system?
Indirectly stimulates LH production
Which hormone acts on Leydig cells to increase testosterone production?
LH
What is the general effect of FSH on the male reproductive system over longer periods of time?
Activates spermatogenesis in Sertoli cells
Which enzyme is involved in increasing the expression of steroidogenic enzymes in the male reproductive system?
$3𝛽$ -hydroxysteroid dehydrigenase
How do gonadotropic hormones LH and FSH differ in their actions within the male reproductive system?
Only FSH activates spermatogenesis in Sertoli cells
What is the role of Inhibin in relation to FSH and GnRH?
Inhibits FSH and GnRH levels
What is the function of Activin A in the male reproductive system?
Controls inflammation and fibrosis
How are low levels of inhibin and high levels of FSH related to infertility?
High FSH is linked to infertility
Which hormone is responsible for fine control of the seminiferous epithelium cycle?
Activin A
What role does AMH play in the male reproductive system?
Facilitates spermatogenesis
Where are significant amounts of estrogens formed in the male reproductive system?
Liver from testosterone and androstanediol
Inhibin B exerts a positive feedback mechanism to stimulate FSH production in the anterior pituitary.
False
Elevated activin A levels during inflammation and infection may contribute to spermatogenic failure and testicular damage.
True
Low levels of inhibin are associated with high FSH levels, which are linked to infertility.
True
Estrogens play a vital role in spermiogenesis and are mainly formed by Leydig cells in the testes.
False
AMH (antimüllerian hormone) is crucial for the regulation of the Hypothalamic-Pituitary-Gonadal Axis.
False
This quiz covers the functions of the male reproductive system, spermatogenesis, hormonal regulation, hormones produced in the reproductive system, hypergonadism, and hypogonadism. It also explores the effects and importance of male hormones in the male reproductive system.
