How is the pooling method applied in IVF?
The pooling method is based on the principle of collecting eggs over several cycles and freezing the resulting embryos in a common pool.
In each collection process:
- The eggs are fertilized by sperm in a laboratory setting.
- The resulting embryos are monitored for several days under special conditions.
- High-quality embryos are selected and frozen.
This cycle is repeated until the desired number of embryos is reached. Then, the highest quality embryos are thawed and transferred to the uterus.
💡 This method provides a high success rate, especially in patients with low egg reserve or those who have previously undergone unsuccessful IVF treatment.
