1
Q

A
- the production of haploid, mature eggs
- in the follicles of the ovaries
2
Q
What is the difference between spermatogenesis and oogenesis in terms of the number of sperm/eggs?

- whereas sperm are formed after puberty

- mature sperm are formed continuously throughout life
- mature eggs are form once puberty starts until menopause
5

- every 28 days
