Swim up and Gradient Methods Used in Assisted Reproduction Techniques on DNA Fragmentation of Spermatozoa

Not Applicable
Completed
Conditions
Male Infertility
Unexplained Infertility
Interventions
Procedure: swim-up, density gradient sperm preparation techniques
Registration Number
NCT01859520
Lead Sponsor
Gazi University
Brief Summary

Sperms are prepared by sperm washing techniques before used in assisted reproductive technologies. Most commonly used sperm preparation methods are the swim up and the density gradient. Recent studies shows that the DNA integrity status of the spermatozoa is related to the success in assisted reproduction techniques. Sperm preparation methods may theoretically cause damage to sperm DNA. Therefore it is important to select the optimum method of sperm preparation causing least sperm DNA damage. Aim of our study is to investigate and compare the effect two different sperm preparation techniques on DNA fragmentation.

Primary Outcome Measures
NameTimeMethod
The change in the rate of DNA fragmentation of spermatozoa after sperm preparation with either swim-up or density gradient techniques.DNA fragmentation assay is performed just before and immediately after the sperm preparation is completed. The time frame is within an hour.

The change in the rate of DNA fragmented spermatozoa will be assessed before and immediately after the sperm preparation is completed, because DNA fragmentation of spermatozoa may be increased in time.
