NCT05500573

Brief Summary

This study aims to demonstrate a reliable method of selecting gender specific sperm. X-bearing spermatozoa and Y-bearing spermatozoa will be identified from the density gradient layers. The selected gender specimen will then be utilized for assisted reproductive fertilization- in vitro fertilization or intrauterine insemination which are routine standard of care procedures.
