[Is there an interest in the addition of hyaluronan to human embryo culture in IVF/ICSI attempts?].

Objective: Several studies have been performed up to date, in order to assess whether the addition of hyaluronan (HA) in human embryo culture could improve the probability of pregnancy, leading, however, to controversies. The aim of the present study was to analyze whether the use of a HA-enriched transfer medium increases clinical pregnancy (PR) and implantation rates (IR), compared with the use of a conventional transfer medium.

Patients And Methods: All IVF/ICSI attempts from unselected women were included from January 2009 to July 2009 (study group).
