Free Anatomy and Physiology Reproductive System Questions and Answers — Questions and Answers
Question 1: Which hormone is primarily responsible for ovulation in females?
- Estrogen
- Progesterone
- Luteinizing hormone (LH) (Correct answer)
- Follicle-stimulating hormone (FSH)
Correct answer: Luteinizing hormone (LH)
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?
- Production of sperm and testosterone (Correct answer)
- Storage of sperm
- Transport of sperm
- Production of seminal fluid
Correct answer: Production of sperm and testosterone
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?
- Ovary
- Uterus
- Fallopian tube (Correct answer)
- Cervix
Correct answer: Fallopian tube
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?
- Vas deferens
- Epididymis (Correct answer)
- Seminal vesicle
- Prostate gland
Correct answer: Epididymis
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?
- Stimulating follicle development
- Thickening the uterine lining (Correct answer)
- Triggering ovulation
- Causing menstruation
Correct answer: Thickening the uterine lining
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.
