I guess it does but it depends on how much you usually produce. I had so much milk with my first I leaked all over and I was nicknamed Elsie because of it. I also had my tubes tied minutes after the birth of my youngest son and while I also breast feed him and I had enough to satisfy him. I did not leak ever so I guess it did lower my ability to produce. I even pumped at the begining to try to increase producion and for times when he needed a bottle and I was out. Good luck.
