Anti-Helicobacter pylori antibodies in cervical mucus: a new cause of infertility

Considering the close correlation found between serum and cervical mucus anti-H. pylori antibody titres, measuring serum antibodies could become an additional test, in particular in couples with unexplained infertility.
