Baby Weight in Men

Has anyone ever done a study on MEN gaining weight after having children? Obviously, many women gain weight during pregnancy and have difficulty losing the pounds afterwards. I think men do too, lol. When my daughter was born over 4 years ago, I was a lean, reasonably muscular 172 lbs. Now I am a doughey 188 (as of this morning), lol. The lifestyle changes necessary to raise a young child sure cramps into the workout routine, doesn't it? I think I've skied 4 times since her birth (used to ski about 8 times a year) and my mountain bike is a spider haven tucked into the back of the garage. And I don't even want to get into the number of planned workouts that were shot to hell because of some unforeseen parental responsibility.
