Objectives

Narrative objectives1

The aim of this study is to investigate if oral supplementation of 700mg/day lactoferrin contributes to
(i) rise its concentration in circulating blood, endometrial fluid, and vaginal secretion,
(ii) correct the dysbiosis in the uterine/vaginal cavity in patients undergoing repeated implantation failure, and
(iii) improve the pregnancy outcome in these patients.

Results

While CE was more prevalent (OR 2.41, 95% CI 1.02-5.63, p = 0.042) in the RIF group (29.1%, n = 117) than in the non-RIF group (14.5%, n = 55), The NLDM rate was similar between the two groups Lactoferrin supplementation improved NLDM in 43.2% of RIF women (n = 37). Within the RIF group, the live birth rate in the subsequent cycles was higher (OR 10.67, 95% CI 1.03 - 110.0, p = 0.046) in women with improved microbiota (57.1%, n = 14) than in those with unimproved microbiota (11.1%, n = 9).
