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.

(i) Measurement of lactoferrin concentration in circulating blood, endometrial fluid, and vaginal secretion

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).
