Question

In the production of sperm, what happens to spermatocytes?

   a. They undergo mitosis to produce sperm cells.

   b. They undergo meiosis to produce sperm cells.

   c. They are sperm cells so they become part of semen and are ejaculated.

   d. They develop into self-renewing stem cells that maintain the testes.

Do women produce more eggs or do men produce more sperm? Why?  

a. Women produce more eggs because the odds of any one egg getting fertilized by a sperm are not good.

b. Women produce more eggs because they can’t move and so are stuck in one place. Because sperm can move, not as many are needed.

c. Men and women produce about equal amounts of sperm/eggs.

d. Men produce more sperm because they produce it all their lives, while women are born with all the eggs they’ll ever have.

Where do the hormones FSH and LH come from and what do they do in women?

a. The pituitary gland; FSH causes a follicle in the ovary to mature and release an egg, and with LH, stimulates estrogen secretion.

b. The hypothalamus; FSH causes a follicle in the ovary to mature and release an egg, and with LH, stimulates estrogen secretion.

c. The prostate gland; FSH causes a follicle in the ovary to mature and release an egg, and with LH, stimulates estrogen secretion.

d. The ovary; FSH causes a follicle in the ovary to mature and release an egg, and LH stimulates estrogen secretion.

A fetal ovary has all the mature eggs it will ever have. True or false?

   a. True. Women have all their mature eggs at birth.

b. False. The eggs in a fetal ovary pause after meiosis I and don’t mature until release from the ovary.
