<s>[INST] Hi I am pregnant with my 3rd and we just found out we are having another girl.  My husband is wondering if its possible maybe he can't produce male sperm to have a boy.  We really wanted a boy this time. Is it possible for a man to not produce the Y sperm to get a boy? I am 30, my husband is 32, my height is 4'11'' and my weight is 125lbs [/INST] No it is not possible for that to happen as have his genome is Y. It is only a matter of luck and you cant do anything to ensure whether you will have a boy or a girl. I would suggest you be happy with your princesses as that is what God has planned for you. Take care. </s>
