Hormonal Regulation Of Male Reproductive System Flashcards
What are Bulbourethral Glands?
Small glands that secrete a clear, viscous fluid that lubricates the urethra and neutralizes acidity in the urethra during ejaculation.
What is the Penis?
The male organ of copulation, composed of erectile tissue that becomes engorged with blood during sexual arousal, facilitating penetration and ejaculation.
What is Testosterone?
The primary male sex hormone synthesized by Leydig cells in the testes, playing a crucial role in the development and maintenance of male reproductive tissues, secondary sexual characteristics, and libido.
What is Gonadotropin-Releasing Hormone (GnRH)?
Secreted by the hypothalamus, GnRH stimulates the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the anterior pituitary gland.
What is Luteinizing Hormone (LH)?
Stimulates Leydig cells in the testes to produce testosterone.
What is Follicle-Stimulating Hormone (FSH)?
Acts on the Sertoli cells in the seminiferous tubules to promote spermatogenesis.
What is Inhibin?
Secreted by Sertoli cells, inhibin inhibits FSH secretion, providing negative feedback regulation of spermatogenesis.
