A Comparison Between Home-made Vitrification & Thawing Media and a Commercially Available Brand on Blastocyst

Phase 2
Completed
Conditions
Blastocyst Disintegration
Interventions
Biological: home made vitrification & thawing kit
Biological: commercially made vitrification & thawing kit
Registration Number
NCT03660904
Lead Sponsor
Benha University
Brief Summary

This study was conducted to evaluate and compare cryo-survival, re-expansion, and implantation rates of Day 5/6 human blastocysts that were vitrified with home-made media (HM) according to (Shady grove protocol) and warmed with gradual Thawing HM according to (Kuwayama protocol)with Global Fast Freeze/Thaw Kits (LifeGlobal, Canada).

Detailed Description

Group 1 blastocysts were vitrified with the Vit HM according to shady grove protocol using open system on cryotopvit. device and thawed with gradual thawing technique using HM according to Kuwayama protocol. Group 2 blastocysts were cryopreserved with the Global Fast Freeze Kitusing open system on cryotopvit. device and thawed using Gobal fast thaw kit. Blastocysts were subsequently cultured for 6-8 h, assessed for survival and expansion, then transferred and the percentages of Positive hCG, clinical pregnancy, implantation, multiple pregnancy and abortion were recorded.
