Abstract:

Objective:
To compare in a strict randomized way the efficiency of two ready-to-use systems for hyaluronic acid (HA)-ICSI: an HA culture dish (PICSI Sperm Selection Device), and a viscous medium containing HA (Sperm Slow).

Design:
Prospective, randomized study

Setting:
GynePro Medical Centers, Bologna, Italy

Patient(s):
50 subjects per treatment group (100 total)

Intervention(s):
100 ICSI treatments randomly carried out with PICSI or with Sperm Slow for sperm selection. Randomization conducted with sealed envelopes. ICSI performed by a single embryologist with 5-year experience in HA-ICSI.

Mean outcome measure(s):
Primary outcome measure: good-quality embryo rate.

Secondary outcome measures:
Oocyte fertilization, pregnancy and implantation rate, and the duration of the ICSI procedure.

Result(s):
Good quality embryo rate comparable between the two groups (58,5% PICSI® versus 56% Sperm Slow™ – P=0.691). Overall, no statistically significant differences in secondary outcome measures except ICSI procedure duration, which was 3 minutes longer (P≤0.001) in the PICSI® group.

Conclusion(s):
Both PICSI® and Sperm Slow™ allow comparable clinical efficiency in selecting HA-bound spermatozoa.
