Anti-laminin-1 antibodies in serum and follicular fluid of women with Hashimoto’s thyroiditis undergoing in vitro fertilization

The aim of this study is to evaluate the presence of anti-laminin-1 antibodies (aLN-1) in sera and follicular fluid (FF) of infertile women affected by Hashimoto’s thyroiditis (HT) undergoing in vitro fertilization (IVF) and its impact on oocyte maturation and IVF outcome. aLN-1 were measured by a home-made enzyme linked immunosorbent assay (ELISA) in: (1) sera and FF from 44 infertile women affected by HT (HTIW) with tubal factor or male factor as primary cause of infertility; (2) in sera and FF from 28 infertile women without HT, with tubal factor or male factor as cause of infertility (infertile controls-ICTR); and (3) in sera from 50 fertile women (FW). aLN-1 serum levels were significantly higher in HTIW when compared with both fertile women and ICTR (P
