Resumen

Objective To investigate the effects of thawing temperature on sperm function after cryopreservation. The technical aspects of sperm cryopreservation have significantly improved over the last few decades. However, a standard protocol designed to optimize sperm motility recovery after thawing has not yet been established. Design Prospective study. Setting Private infertility institute and university-based research laboratory. Patient(s) Eighty consenting normozoospermic patients consulting for infertility. Intervention(s) Spermatozoa from donor semen samples were thawed at different temperatures. Main Outcome Measure(s) Sperm motility, viability, adenosine-5'-triphosphate (ATP) content, acrosomal status, and DNA integrity were evaluated as a function of thawing temperature in cryopreserved human sperm samples. Result(s) Thawing at 40°C resulted in a statistically significant increase in sperm motility recovery compared with thawing at temperatures between 20°C and 37°C. There were no statistically significant differences in sperm viability, acrosomal status, ATP content, and DNA integrity after thawing at 40°C compared with thawing at temperatures between 20°C and 37°C. Conclusion(s) Sperm thawing at 40°C could be safely used to improve motility recovery after sperm cryopreservation.
