Relationship between hyaluronic acid binding assay and outcome in ART: a pilot study.
The sperm-hyaluronan binding assay (HBA) is a diagnostic kit for assessing sperm maturity, function and fertility. The aim of this prospective cohort pilot study was to evaluate the relationship between HBA and WHO sperm parameters (motility, concentration and detailed morphology) and possible influence of sperm processing on hyaluronic acid binding. A cohort of 68 patients undergoing a first combo in vitro fertilisation/intracytoplasmic sperm injection treatment after failure of three or more intrauterine insemination cycles were included in the study. Outcome measures studied were fertilisation rate, embryo quality, ongoing pregnancy rate and cumulative pregnancy rate. HBA outcome improved after sperm preparation and culture, but was not correlated to detailed sperm morphology, concentration or motility. HBA did not provide additional information for identifying patients with poor or absent fertilisation, although the latter had more immature sperm cells and cells with cytoplasmic retention present in their semen. HBA outcome in the neat sample was significantly correlated with embryo quality, with miscarriage rates and ongoing pregnancy rates in the fresh cycles, but not with the cumulative ongoing pregnancy rate. No threshold value for HBA and outcome in combo IVF/ICSI treatment could be established. The clinical value for HBA in addition to routine semen analysis for this patient population seems limited.
