PG - 36-41 LID - 10.1111/aji.12430 [doi] AB - PROBLEM: We evaluated associations between brain-derived neurotrophic factor (BDNF) and neurotrophin-4 (NT4) and pregnancy outcome in women undergoing in vitro fertilization-embryo transfer (IVF-ET). METHOD OF STUDY: Sera obtained on days 24 and 28 of an IVF cycle from women with a live birth, spontaneous abortion, biochemical pregnancy, not pregnant, or an ectopic pregnancy were retrospectively analyzed for BDNF and NT4 by ELISA. RESULTS: Median BDNF levels were higher in women with a live birth compared to women with an ectopic pregnancy (P < 0.0001), spontaneous abortion (P < 0.0001), or a biochemical pregnancy (P = 0.0004), but not in women who did not become pregnant. NT4 was detected in <25% of sera and did not differ by outcome. There was no association between BDNF level and oocyte or pre-transfer embryo parameters. CONCLUSION: Decreased circulating BDNF early in an IVF cycle is associated with adverse peri- and/or post-implantation events and subsequent pregnancy failure. CI - (c) 2015 John Wiley & Sons A/S.
