Abstract

Purpose

Magnetic activated cell sorting (MACS) eliminates apoptotic spermatozoa based on the presence of externalized phosphatidylserine residues. We evaluated the outcome of male fertility treatment when intracytoplasmic sperm injection (ICSI) into human oocytes was performed with non-apoptotic MACS-selected spermatozoa.

Methods

196 couples were treated by ICSI following spermatozoa preparation by MACS (study group; 122 couples) or density gradient centrifugation (DGC) (control group; 74 couples). Fertilization, cleavage, pregnancy, and implantation rates were analyzed.

Results

The percentage of sperm with normal morphology after MACS selection was improved. Cleavage and pregnancy rates were higher, respectively, in the study group than in control. A slightly higher implantation rate was also observed in the study group.

Conclusions

MACS selection of human spermatozoa increased cleavage and pregnancy rates in oligoasthenozoospermic ART cases. This novel method for selecting non-apoptotic spermatozoa for ICSI is safe and reliable, and may improve the assisted reproduction outcome.
