What effects does pregnancy have on breast implants ?

It will have: no effects on the implants, but the breasts themselves will likely become larger and more glandular due to hormonal changes.

It varies: Good afternoon! Since every woman's breasts react differently to the deluge of hormones during pregnancy, some women's breasts continue to do well after pregnancy while others may require some sort of "tweak" to give the best result. It is important to remember that studies have shown that it is safe to breast feed with implants.
