Testosterone.

Question 11

What is the role of FSH in oogenesis?

Answer 11

Follicle-stimulating hormone (FSH) stimulates the growth and maturation of ovarian follicles.

False.

Question 16

What structure is formed after the completion of meiosis II in oogenesis?

Answer 16

A mature ovum.

Question 17

Which cells provide nourishment to developing sperm cells?

Answer 17

Sertoli cells.

Question 18

Fill in the blank: The polar bodies produced during oogenesis are _____.

Answer 18

non-functional.

Question 19

What is the role of LH in spermatogenesis?

Answer 19

Luteinizing hormone (LH) stimulates testosterone production from Leydig cells.

Question 20

What is meant by the term ‘spermatogonia’?

Answer 20

The diploid precursor cells that divide to form sperm cells.

Question 21

What triggers ovulation in the female menstrual cycle?

Answer 21

A surge in luteinizing hormone (LH).

True.

Question 23

How many chromosomes do spermatids have?

Answer 23

23 chromosomes.

Question 24

What is the significance of the acrosome in sperm cells?

Answer 24

It contains enzymes that help penetrate the egg’s outer layers.

Question 25

Fill in the blank: The process of _____ leads to the formation of the zona pellucida around the oocyte.

Answer 25

folliculogenesis.

Question 26

What occurs during the follicular phase of the menstrual cycle?

Answer 26

Follicles mature and one becomes dominant, leading to ovulation.

Question 27

What is the role of the corpus luteum?

Answer 27

It secretes progesterone to maintain the uterine lining after ovulation.

Question 28

True or False: Spermatogenesis can be affected by environmental factors.

Answer 28

True.

Question 29

What is the term for the process by which sperm gain motility?

Answer 29

Sperm maturation.

Question 30

What is the primary purpose of meiosis in spermatogenesis and oogenesis?

Answer 30

To reduce the chromosome number by half to produce haploid gametes.

Question 31

Fill in the blank: The meiotic division of oocytes is completed only upon _____.

Answer 31

fertilization.

Question 32

What happens to the secondary oocyte if fertilization does not occur?

Answer 32

It degenerates and is expelled during menstruation.

Question 33

what is the purpose of the fallopian cilia?

Answer 33

to help move the fertilized oocyte to the uterus for implantation

Question 34

what happens when there's a reduced number in fallopian cilia?

Answer 34

improper implantation of the fertilized egg can occur outside the uterus
