1. What is the meiotic process of egg cell production?
2. Where is the sperm stored
before it was transported to vas deferens?
3. Which hormone decreases the activity of the FSH?
4. Which exocrine gland in female reproductive system is responsible for lubrication and is the counterpart of male's Bulbourethral gland?
5. Which process of embryonic development makes the blastula divided into three layers of: ectoderm, mesodem and endoderm?
5. What is the cell inside seminiferous tubules that supports and nourishes spermatozoa?
6. In aging, this period signifies the cessation of menstruation.
8. What do you call the tail of the sperm that is responsible for its motility?
9. What is the first sign of puberty in female?
10. If you were the one to marry Prince William, what is the chance that you will have a son with blonde hair?
