Each human has one natural range they fall into automatically. Men and women have different hormones. Testosterone in a man causes the vocal cords to thicken therefore vibrating at a deeper resonating sound. Women have less testosterone and more estrogen causing the vocal cords to be thinner and making a higher pitch sound. This testosterone effect explains why boys sing and talk in feminine voice before puberty. !!
