HBA® Slide
Sperm diagnostics based on Hyaluronic acid binding
The Hyaluronic Binding Assay (HBA®) is an important
diagnostic tool for suspected male infertility in the
analysis of semen. In a matter of minutes the HBA® slide
provides an answer to the proportion of mature binding
spermatozoa in the sample (The HBA® score %).
Calculate % Bound = 100 x Bound Motile/Total Motile
Facts on Hyaluronan (Hyaluronic acid -HA):
•
Hyaluronan is the major component of the Cumulus
Complex surrounding the human oocyte
•
A sperm’s ability to bind to HA is a biochemical marker
of the sperm’s maturity and DNA integrity
•
Only mature spermatozoa with developed receptors
for HA can bind
Viewed in the microscope, bound sperm are differentiated
from unbound sperm by their beating tails with heads that
make no progressive movement.
Unbound, Motile Sperm
Helps to significantly reduce Pregnancy Loss Rate
Worrilow et al. (2012) found that a combination of the
diagnostic abilities of the HBA® slide and the HA-sperm
selection abilities of the PICSI® dish improved Clinical
Pregnancy Rate and significantly reduced Pregnancy Loss
Rate in ICSI patients diagnosed with low HBA® scores (≤65%
binding ratio).
This study also demonstrated that 15% of all ICSI patients
have a low HBA score (≤65%) and would benefit from HA
sperm diagnostics and selection.

Clinical documentation
The ability to bind to HA correlates to:
•
Maturity
•
Strict morphology
•
High DNA integrity
•
Reduced chromosomal aneuploidies
The HBA® slide is found to be useful in predicting the
ability of spermatozoa to fertilize oocytes in IVF and is
helpful in distinguishing semen samples suitable for IVF or
ICSI (Breznik et al., 2013)
