What Happens in the Laboratory?

Once eggs are retrieved, they go straight to the lab. Here’s what happens next:

• Assessment: Not every follicle contains an egg, and not every egg is mature enough for fertilization.

Fertilization Methods:

• Standard IVF: Eggs and sperm are placed together to fertilize naturally. 🧫

• ICSI: A single sperm is injected directly into each egg (often used for male-factor challenges). 💉

• Monitoring: Embryologists check for "pronuclei" the next morning to confirm normal fertilization.

• Development: Embryos grow for 2 to 6 days until they reach the blastocyst stage, which offers the highest chance of success. 📈
