Sydney IVF Cleavage / Blastocyst Medium
Sequential media for day 1–3 and day 3–5/6 culture.
What it is and how it's used
Same changeover considerations as any sequential system: the day-3 move is a handling event.
Typical failure modes
- Blastocyst rate falls after a Blastocyst-medium lot change.
- Arrest around compaction after a slow or cool changeover.
What to check first
- Lot dates vs KPI change.
- Changeover time-out and stage temperature by probe.
- Compare by incubator.
