What is the right age range to conceive a baby for men and women?

When Raj Shamani asked Dr Vijayant Gupta the right age to conceive, the doctor said the best age range to conceive is when both a man's and woman's bodies are mature and at their peak fertility, which is between the ages of 20-30. After 30 the fertility reduces. He further shared his perspective on freezing eggs and sperms.
