Week 11 Learning Outcomes

Question 1

What are the main organs of the male reproductive system?

Answer 1

Testes, epididymis, vas deferens, seminal vesicles, prostate gland, bulbourethral glands, penis

The testes produce sperm and hormones, while the other structures contribute to sperm transport and maturation.

Question 2

What are the main organs of the female reproductive system?

Answer 2

Ovaries, fallopian tubes, uterus, cervix, vagina

The ovaries produce eggs and hormones, while the other structures are involved in egg transport and support of a potential pregnancy.

Question 3

What is spermatogenesis?

Answer 3

The process of sperm cell development in the male reproductive system

It involves the transformation of spermatogonia into mature spermatozoa through mitosis and meiosis.

Question 4

What is oogenesis?

Answer 4

The process of egg cell development in the female reproductive system

It involves the transformation of oogonia into mature ova, primarily occurring before birth and completing at ovulation.

Question 5

Fill in the blank: The female reproductive cycle includes the _______ and ovarian cycles.

Answer 5

uterine

The uterine cycle prepares the endometrium for potential implantation of a fertilized egg.

Question 6

What hormones influence the female reproductive cycle?

Answer 6

Estrogen, progesterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH)

These hormones regulate the menstrual cycle, ovulation, and preparation for potential pregnancy.

Question 7

How does male fertility change across the lifespan?

Answer 7

Gradual decline in testosterone levels and sperm production with age

While men can remain fertile into older age, the quality and quantity of sperm may decrease.

Question 8

How does female fertility change across the lifespan?

Answer 8

Decline in fertility begins in the late 20s, with a significant decrease after age 35

Menopause typically occurs around age 50, marking the end of reproductive capability.

Question 9

Compare the timing of spermatogenesis and oogenesis.

Answer 9

Spermatogenesis occurs continuously from puberty onwards; oogenesis is cyclical, with a finite number of eggs present at birth

Oogenesis is characterized by long pauses and the completion of meiosis only upon fertilization.

Question 10

True or False: Both spermatogenesis and oogenesis result in the production of multiple gametes per cycle.

Answer 10

False

Spermatogenesis produces millions of sperm continuously, while oogenesis typically produces one viable egg per cycle.
