Free Anatomy and Physiology Reproductive System Questions and Answers

Question 1

Which hormone is primarily responsible for ovulation in females?

Accepted Answer

Luteinizing hormone (LH)

Answer

A surge in LH triggers ovulation, the release of an egg from the ovary. Estrogen and FSH help develop the follicle, and progesterone maintains the uterine lining after ovulation.

Question 2

What is the primary function of the testes in males?

Accepted Answer

Production of sperm and testosterone

Answer

The testes are the male gonads responsible for producing sperm (spermatogenesis) and the hormone testosterone, which regulates male secondary sexual characteristics.

Question 3

Where does fertilization of an egg typically occur?

Accepted Answer

Fallopian tube

Answer

Fertilization usually occurs in the fallopian tube (also called the uterine tube or oviduct). The fertilized egg then travels to the uterus for implantation.

Question 4

Which structure in the male reproductive system is responsible for storing and maturing sperm?

Accepted Answer

Epididymis

Answer

The epididymis, located on the back of the testes, stores sperm and allows them to mature and gain motility before being transported through the vas deferens.

Question 5

What is the role of progesterone during the menstrual cycle?

Accepted Answer

Thickening the uterine lining

Answer

Progesterone is produced by the corpus luteum after ovulation and prepares the uterine lining (endometrium) for potential implantation of a fertilized egg. If fertilization does not occur, progesterone levels drop, leading to menstruation.
