Ways to pre-determine infant gender

Patient: Greetings. i am a middle aged woman, i currently have 4 girls, the eldest is 13 and the youngest is 4. i would really like to have a boy.is there any affordable medical way to pre-determine the gender of my baby? Thank you very much.

Doctor: There is no method to predetermine the sex of an unconcieved child. You can determine the sex of the child while in ut tero through an ultrasound during the pregnancy. I hope this helps. All the best.
