Breast augmentation does not inhibit pregnancy in any way. I have several patients who have had multiple pregnancies after their breast augmentation.
With reference to breastfeeding, many of my patients have nursed after having a breast augmentation.
I put all my primary breast implants in through the armpit behind the pectoralis muscle, and therefore the implant has little to do with the breast gland itself. There have been some reports that breast augmentations at the edge of the areola can interrupt some of the ducts and, therefore, decrease the amount of milk being produced during nursing.
The short answer to your question is that breast augmentation through the armpit (transaxillary) in no way inhibits pregnancy or nursing.

Yes you can still get pregnant and breast feed after having a breast augmentation, either with a saline or silicone get implant. The breast will react the same as it would if you had not had an implant so you may gain or lose volume in the breast after breast feeding.
