Question

Which male reproductive structure adds secretions to the sperm during ejaculation that carry and provide nutrients as part of the semen?

Answers

  1. Penis
    • Rationale:

      Sperm is carried to the urethra via the vas deferens; urethra passes through the penis. The penis, however, does not add secretions to the sperm.

  2. Urethra
    • Rationale:

      The urethra which passes through the penis. The urethra, however, does not add secretions to the sperm.

  3. Vas deferens
    • Rationale:

      The vas deferens carries sperm to the urethra. This structure, however, does not add secretions to the sperm. These secretions both carry and provide nutrients to the sperm.

  4. Prostate gland
    • Rationale:

      The prostate gland, along with the seminal vesicles, add secretions to the sperm during ejaculation.

Overview

The male reproductive system produces sperm in the testes. Semen is a male reproductive fluid that contains spermatozoa.

Explanation

Learning Outcomes

The vas deferens, an internal structure of the male reproductive system, carries sperm to the urethra which passes through the penis. During the process of ejaculation, both the prostate gland and the seminal vesicles add secretions to the sperm. This secretion carries and provides nutrients to the sperm as part of semen.
