It's not the Sex but the Anatomy.
It's really all about the anatomy but that's the case whether the patient is a man or a woman (and, of course, there are trans-sexual patients, so that complicates those designations further). The surgeon has to look at what the patient's characteristics are in terms of skin, fat, and muscle (along with the abdominal wall) and then propose one or more procedures that will be acceptable to the patient. Biologically-born women have the additional factor of pregnancy to consider, whether past or anticipated, but a significant weight gain and subsequent loss - for any reason - may lead to a similar appearance, regardless of the DNA.
One can make some generalizations but for the individual patient, the surgery needs to be individualized. And that's true whether the patient is a man or a woman.
I hope that this helps, and good luck,
