Abstract


Structured abstract:

Objective: To determine if a less expensive, easier, and faster to perform HBA test is clinically equal to the more complicated, technically challenging and expensive SPA test as a reliable indicator of sperm fertilizing capacity.

Design: Prospective study.

Setting: Andrology laboratory within In Vitro Fertilization Program.

Patient(s): Semen samples from 26 infertility couples were analyzed. Both, normal and male factor patients were included.

Intervention(s): Male partner screening with the HBA and the SPA tests.

Main Outcome Measure(s): Relationship between HBA and SPA test results.

Result(s): The data obtained in this study showed no statistically significant relationship between the HBA and SPA results. The mean HBA scores 76.3%, 61.3% and 76.8% were statistically not significantly different as compared to patients with negative (<5), grey zone (5-8) and for positive (>8) sperm capacitation index values.

Conclusion(s): The HBA is not predictive of the results of the SPA. Hence, if the SPA is a reliable indicator of the fertilizing capacity of human spermatozoa then the HBA is not and we do not suggest replacing SPA with HBA.
