Vocabulary flashcards covering the main structures, fluids, and functions of the male reproductive system as introduced in the lecture notes.

Seminiferous tubules

Coiled tubules inside the testes where sperm cells are produced.

Interstitial (Leydig) cells

Cells located between seminiferous tubules that primarily secrete testosterone.

Epididymis

Long, coiled duct atop each testis that stores and matures sperm cells before ejaculation.

Vas deferens

Muscular tube that transports sperm from the epididymis to the ejaculatory duct.

Seminal vesicles

Paired glands that secrete a thick, alkaline, fructose-rich fluid contributing to semen volume.

Prostate gland

Single gland surrounding the urethra that releases a milky fluid to nourish and protect sperm.

Bulbourethral (Cowper’s) glands

Small glands that release a clear, lubricating pre-ejaculatory fluid into the urethra.

Semen

Mixture of sperm and secretions from seminal vesicles, prostate, and bulbourethral glands.

Scrotum
