Answers
Yes there are other ways of reproduction a well other than having sex.
Test tube babies are now a common way of reproduction without having sex.
The sperm from the male is collected from the father or the sperm bank (if the woman does not have a husband or her husband can't make her pregnant) and the ovum from the female is taken out by certain surgeries.
The egg and the sperm is fertilized outside of the bodies, in the test tube.
One reason for doing this is that, the parents can have a baby of their dreams. If they want their baby to be tall/pretty/intelligent/athletic, they can have it all by bringing in some difference in the genes which is not possible inside of the body if the baby was produced through sexual Intercourse.
The mother may carry the baby or some other woman might carry the baby by transferring the zygote in their body. If some other woman carries the baby, it'll be known as surrogacy.
