A Sibling Oocyte Study- Comparison of ZyMotTM Microfluidics Device to Density Gradient for Sperm Selection During ICSI
In Brief
A clinical study evaluating ZyMot Multi Sperm Separation Device (850 ul) and Density Gradient Centrifugation for ART. Completed, enrolled 108 participants across 1 site.
Detailed Summary
The primary objective of this study is to evaluate whether the percentage of good quality embryo formation following Intracytoplasmic Sperm Injection (ICSI) is improved with the use of ZyMot method of microfluidic sperm separation compared to density gradient.
Study Details
Timeline
Interventions
850 uL of untreated semen will be directly deposited into the inlet port of the ZyMotTM Multi device, followed by placement of 750 uL culture medium in the outlet port and throughout the upper collection chamber. The device will then be incubated in a humidified 37C CO2 incubator for 30 minutes. During incubation, the healthiest and most motile sperm will swim through the microporous filter and into the upper collection chamber, where they will be recovered via the outlet port. 500 uL of the sperm sample will be removed and placed in a separate tube for analysis and insemination.
Density gradient centrifugation will be performed using a one-layer preparation of 90% Isolate in 15 mL conical tubes. Semen will be layered over 1 mL of gradient and then centrifuged for 15 min at 300xg. The supernatant will be removed and discarded. The sperm pellet will be washed by mixing with Multipurpose Handling Medium Complete and centrifuging the sample for 5 min at 400xg. After the wash, the supernatant is removed and discarded and the pellet is re-suspended in culture medium, assessed for sperm parameters, and held at room temperature until insemination.
