Brief summary

This is a randomized controlled trial comparing density gradient centrifugation and microfluidic sperm sorting in patients undergoing intrauterine insemination to evaluate cumulative pregnancy outcomes.

Detailed description

Study participants will be randomized to either standard sperm preparation (density gradient centrifugation) versus sperm preparation with the Zymot Multi sperm preparation device for their three month intrauterine insemination treatment course. Patients will follow standard treatment plans designed by their fertility physician and will be followed until referred for prenatal care at 8-10 weeks of pregnancy to determine pregnancy outcomes.
