One frequent question I hear is, "Does doing a blastocyst transfer increase my chance of having a boy." Urban legend has it that there is a greater chance of a boy with a blastocyst transfer because male embryos supposedly develop more quickly than females.

Now a study published in the October 2009 edition of "Fertility and Sterility" shows that "male …
