Answer to Question 1

1
one

Answer to Question 2

3
Rationale:
1. Sperm are produced in the seminiferous tubules in the testes, and are not affected by a vasectomy.
2. A vasectomy does not affect motility or fertility of sperm.
3. Sperm cannot reach the outside of the body in a man who has a vasectomy. The main function of the vas deferens, which is ligated in a vasectomy, is to squeeze the sperm from their storage site into the urethra.
4. Sperm cannot penetrate an ovum, but only because they cannot reach the outside of the body due to the ligation.
