Hyaluronan binding assay does not predict pregnancy rates in IUI cycles in couples with unexplained infertility.

PURPOSE: To investigate the relationship between hyaluronan binding (HB) assay and pregnancy rates in intrauterine insemination (IUI) cycles.

METHODS

This prospective cohort study was done in Hacettepe University, a tertiary care center for reproductive medicine. Seventy-one consecutive couples who suffered from unexplained infertility and underwent controlled ovarian hyperstimulation (COH) and IUI were enrolled into the study.

RESULTS

From the 71 IUI patients, the clinical pregnancy rate was 14.1% (10 of 71). HB ratio from the overall patient number was 48.6±25.9. The mean HB ratio in pregnant and non-pregnant groups was comparable (50.2±25.2 vs. 48.3±26.2, respectively, p>0.05).

CONCLUSIONS

Hyaluronan binding assay does not predict pregnancy rates in IUI cycles in couples with unexplained infertility.
