i have a female friend , who want to give a birth to male child , it is her ist pregnancy, what should she do for this?

None of the home methods work. The only way would be to get IVF with selected male sperm - and gender selection like this is illegal in most countries.

If she's already pregnant, there is a 50/50 chance of a boy no matter what she does. Gender is determined at the moment of conception: either a male sperm makes it to the egg or a female sperm.

The male determines the sex of the child, not the female. It's already set at conception so the mother can change nothing or effect it in any way.

There is nothing she can do and will have to pray she gets her wish. My friend wanted a son but she had 5 girls before she got her son, Good Luck
