Answer to Question 1

Directly after ejaculation, the semen initially coagulates into a thick mucus-like liquid, probably an evolutionary development to aid in procreation by decreasing the chances it would leak back out of the vagina. after 5 to 20 minutes, the prostatic enzymes contained in the semen cause it to thin out and liquefy. if it does not liquefy normally, coagulated semen from heterosexual men may be unable to complete its movement through the cervix and into the uterus.

Answer to Question 2

Sperm is required in such large numbers because during procreation only a small fraction of them ever reaches the ovum during procreation. Also, the sperm work together to achieve fertilization; for example, many die and block the os of the cervix for the other sperm, and the combined enzyme production of all sperm are necessary for a single spermatozoon to fertilize the ovum.
