Question

How can you determine the sex of a baby

Answer 1

From reproductive organs

Answer 2

In truth, no one can never find out until the 20th week through an ultrasound scan (even then, it isn't 100% guaranteed). Some parents choose to wait until thebaby is born to find out. Many mothers swear they already knew their baby's gender before the babycame out, and even before their ultrasound scans.
