Abstract
- Purpose
We compared semen quality and sperm DNA fragmentation in cancer patients who underwent sperm banking and controls who underwent sperm cryopreservation for assisted reproductive technology (ART).
Materials and Methods
A total of 132 men, 65 cancer patients and 67 controls, were prospectively enrolled and performed sperm cryopreservation for fertility preservation from May 2019 to February 2021. Sperm quality was determined by measuring semen volume, sperm concentration, sperm motility, and sperm DNA fragmentation index (DFI). Sperm quality and sperm DFI were compared in cancer patients and controls.
Results
The major cancers of the 65 cancer patients were leukemia (26.2%), testicular cancer (23.1%), and lymphoma (20.0%). Sperm concentration, sperm total motility, and sperm progressive motility were significantly lower in cancer patients than in controls. Sperm DFI was significantly higher in cancer patients than in controls (24.32%±15.69% vs. 19.11%±11.63%; p=0.033). After excluding 8 cancer patients who received chemotherapy before sperm banking, sperm concentration, sperm total motility, and sperm progressive motility were significantly lower in cancer patients than in controls, but there was no significant difference in sperm DFI for cancer patients and controls (23.14%±12.79% vs. 19.11%±11.63%; p=0.069).
Conclusions
Sperm quality was lower in cancer patients than in controls. There was no difference in the sperm DFI of cancer patients prior to chemotherapy and men presenting for sperm cryopreservation for ART. We recommend that all men who are planning cancer therapy should be offered sperm banking prior to gonadotoxic chemotherapy as a standard of fertility preservation.
