QCM : Human Reproductive Anatomy and Function — 9 questions

Explication

The penis is the external male reproductive organ responsible for sexual intercourse, urination, and ejaculation. It contains erectile tissue that fills with blood during an erection. The testes are internal organs located within the scrotum, responsible for sperm production and hormone secretion. The prostate gland is an internal gland that contributes fluid to semen. The vas deferens is a duct that transports sperm from the testes to the urethra but is not an external structure.

Explication

The scrotum's main role is to regulate the temperature of the testes, maintaining it around 34-35°C, which is essential for healthy spermatogenesis.

Explication

Males typically have two testes, which are paired organs responsible for sperm production and hormone secretion. The other options are incorrect: most males do not have only one, three, or four testes.

Explication

The seminal vesicles produce a fructose-rich fluid that makes up about 60% of semen and provides energy for sperm motility.

Explication

Female external structures, including the vulva, labia, and clitoris, primarily serve to protect internal reproductive organs, provide sensory input, and facilitate sexual arousal. They do not directly produce hormones or regulate the menstrual cycle, which are functions of internal reproductive organs like the ovaries and the endocrine system.

Explication

The penis contains two corpora cavernosa and one corpus spongiosum, which are cylindrical bodies made of erectile tissue.

Explication

The foreskin, or prepuce, is a fold of skin that covers the glans penis in uncircumcised males.

Explication

The epididymis is the coiled tube where sperm mature and are stored temporarily before ejaculation.

Explication

The prostate gland secretes a milky fluid that nourishes sperm and is located encircling the urethra below the bladder.
