Lactation Outcomes in More Than 3500 Women Following Primary Augmentation: 5-Year Data From the Breast Implant Follow-Up Study

Aesthet Surg J. 2019 Jul 12;39(8):875-883. doi: 10.1093/asj/sjy221.


Background: Women with breast implants may have concerns about their ability to successfully breast-feed. The Breast Implant Follow-up Study (BIFS-001) is a large, 10-year observational study evaluating the performance and safety of Natrelle round silicone gel-filled breast implants.

Objectives: This analysis compared lactation outcomes in women enrolled in BIFS-001 who gave birth after they underwent primary augmentation with Natrelle round silicone implants or saline implants.

Methods: At baseline and annually after surgery (>5-year visit window), patients completed questionnaires regarding pregnancy and lactation. Comparisons were made using summary statistics and odds ratios with 90% confidence intervals (OR [90% CI]).

Results: A total of 4679 subjects gave birth at least once after primary augmentation for a total of 5736 live births during the study (silicone, 3695 births; saline, 2041 births). Of these, 3715 (79.4%) women breast-fed at least 1 child, resulting in 80.0% (silicone) and 75.9% (saline) of babies being breast-fed. The most common complication was insufficient milk production, which was reported for 19.6% (silicone) and 19.8% (saline) of single births (OR, 0.94 [0.83, 1.06]). Complications occurred at similar rates in each group when evaluated by incision type, implant size, pocket location, and age.

Conclusions: In this large group of women who gave birth after primary breast augmentation with Natrelle round silicone implants or saline implants, most were able to breast-feed their infants without complications. Lactation complications were comparable between the silicone and saline cohorts, and the incidence was comparable to reports in the general population of women who breast-feed.
