Semen normally contains secretions from the seminal vesicles and the prostate gland, and about 50 to 150 million sperm per milliliter. Why is sperm required in such large numbers?
What will be an ideal response?
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.
