According to a University of Kentucky study that included 132 women who sought breast lifts or augmentation, in direct contrast to what many women may believe, breastfeeding does not cause saggy breasts.

It is noteworthy of mention that most of the women in question had been pregnant at least once and nearly 60 percent had breastfed at least once.

The BBC News reports that researchers analyzed each woman’s medical history, height and weight, smoking habits, and pre-pregnancy bra cup size. They found no difference in extent of breast sagginess between women who’d breastfed and those who hadn’t.

Nonetheless, it should be pointed out that the study authors did conclude that pregnancy itself was a factor.

The degree of sagginess increased each time a woman was pregnant. Smoking was another factor that contributed to breast sagginess.

To quote study author Dr. Brian Rinker, the BBC News reported that he says: "Smoking breaks down a protein in the skin called elastin, which gives youthful skin its elastic appearance and supports the breast."
