can do the same thing. Once again, as the weaker male-chromosome sperm
die off faster than their female-chromosome partners, the chances of
conceiving a girl go WAY up. That's why it's important for a man to
keep his sperm at normally regulated temperatures... as cool as
possible.
The best way to do this? Boxer shorts. Boxers allow the testicles to
hang naturally away from the body, keeping lower seminal temperatures.
Briefs allow the testicles to be hugged tightly to the body,
enveloping them in warmth that could kill off hoards of male sperm.
And if you're trying to conceive a boy... you don't want that! Go with
boxers.
