I believe this.I have taken some hard squar shots in the balls and it did hurt for a few seconds but I was able to fight without missing a beat!It just made me really madd and fight even harder!! But as for the women, I have seen some almost go into shock from the pain from a hard kick in the genitals when I was a assistant coach on a women's soccer team.But a women's genitals are also highly sensitive to any type of strike.And can be very dangerious as well!
