Inside the embryology laboratory

The laboratory is the quietest room in the clinic. Temperature, humidity and the make-up of the air are held steady, and the light stays low around the clock.

The first five days

Every day has its own name and its own check.

• Day 0 — fertilisation
• Day 1 — assessing the pronuclei
• Day 3 — the cleavage stage
• Day 5 — the blastocyst

An embryologist never hurries. Hurry here costs a protocol.
