Level I Flashcard 'Male Reproductive System'

The primary function of the testis is to produce sperm and hormones, particularly testosterone.

Seminiferous tubules are tightly coiled structures within the testis where sperm are produced.

The epididymis is responsible for the maturation and storage of sperm.

The ductus deferens is a muscular tube that transports sperm from the epididymis to the ejaculatory duct.

The prostate gland surrounds the upper portion of the urethra and contributes to semen production.

Seminal vesicles produce a fluid that nourishes sperm and forms a significant portion of semen.

Semen has a slightly alkaline pH that helps neutralize the acidic environment of the female vagina, aiding sperm survival.

Bulbourethral glands secrete a pre-ejaculatory fluid that lubricates the urethra and neutralizes acidity.

Semen is composed of sperm, seminal fluid from seminal vesicles, prostate fluid, and secretions from bulbourethral glands.

Enzymes in semen enhance sperm motility and help in the liquefaction of semen after ejaculation.
