Continuous Single Culture-NX (CSCM-NX) is a clinically-proven, low lactate, single-step culture medium that helps improve blastocyst development. It is intended for use in assisted reproductive procedures which include human gamete and embryo manipulation. These procedures include the use of CSCM-NX as a culture medium from fertilization through blastocyst stage. This medium is optimized to be used in an uninterrupted culture system, without dish change or medium renewal.
Unlock the Full Potential of CSCM-NX with the Day 0 Workflow
Introducing oocytes into CSCM-NX on Day 0 directly after identification, instead of waiting until after fertilization, maintains a consistent environment while eliminating dish changes and simplifying your workflow.
Day 0 with CSCM-NX
Traditional Method
*Dish must be changed after conventional insemination. ICSI performed per established lab procedures with buffered media.
Better Results Start at Day 0
Studies show that when labs follow the Day 0 workflow with CSCM-NX, they see significant improvements in embryo culture outcomes.
Overall higher Day 5 and 6 blastocyst utilization rate (BUR), even when accounting for patient age1,2
Increase BUR in patient population >38 years old3
Higher euploidy rate than CSCM4
Improvement in clinical pregnancy and reduction in miscarriage rates5
Increase in higher expansion grade blastocysts6
Improved trophectoderm and inner cell mass grades6
Reduced embryo discards6
CSCM-NX/C vs. Competitors
*Differences were significant (p<0.05)
† More usable blasts in traditional media on Day 6 due to higher BUR on Day 5 in low lactate media.
Results complied from clinical use data collected from 2020—2023.
