प्रश्न
Give Reasons
Millions of sperms are produced at ejaculation yet one sperm actually fertilizes the ovum. Explain.
उत्तर
Only one ovum is released at a time in the human female during ovulation. Although millions of sperms are ejaculated only one sperm is enough to fertilize the single ovum. This arrangement is to control and maintain the growth rate of the human population. The ovum secretes a protective wall that prevents the entry of other sperms.
