What are the Three Structures That Add Secretions to the Sperm

Question

What are the three structures that add secretions to the sperm to make up semen?
A) seminal vesicles, Leydig cells, and prostate gland
B) prostate gland, seminal vesicles, and seminiferous tubules
C) bulbourethral glands, Leydig cells, and seminal vesicles
D) seminal vesicles, prostate gland, and bulbourethral gland

Accepted Answer

Seminal vesicles, prostate gland, and bulbourethral gland are the three structures that add secretions to the sperm to make up semen. The seminal vesicles contribute the majority of the volume of semen, providing fructose as an energy source for sperm. The prostate gland adds an alkaline fluid that neutralizes acids in the urethra and vagina. The bulbourethral gland secretes a clear, slippery fluid that lubricates the urethra and helps to neutralize any remaining acidic urine in the urethra prior to ejaculation.
