what u need to understand is that we have 23 pairs of chromosome and from that 22 pairs are autosome and its configuration are same in males and females . 
but the rest 1 pair are there which is diffrent . in males that is XY and in females that is XX ., 
Y chromosomes are the chromosomes which depict the maleness factor.. 
thatswhat the reason the males have XY chromosome instead of XX . 
The process of biological sex differentiation (development of a given sex) involves many genetically regulated, hierarchical developmental steps. More than 95% of the Y chromosome is male-specific and a single copy of the Y chromosome is able to induce testicular differentiation of the embryonic gonad.
THERE ARE ALSO SOME HERMONAL RELATION THAT IS THE TESTEROSTERONE AND ANDROGEN HERMONES ARE SOME WHAT RELATED TO Y CHROMOSOME ONLY , AND WITH X CHROMOSOME THEY WILL NOT SECRETE . 
HOPE IT CLEARS YOUR DOUBT 
ALL THE BEST ..
