Update in Embryo Freezing and Endometrial Preparation. (attatched picture file). The Slow freezing vs Vitrification in each stage of embryo.
In Thailand, Slow freezing has been using in many centers and experienced a good result. As we were discussing, it will depend on how is the experience in each center. Vitrification is becoming more popular but some centers are still keeping Slow freezing as the first choice freezing. Blastocyst is more acceptable that the Vitrification technique is more better in outcome.
Three mothods has been used in endometrial preparation.
1. Natural cycle preparation : difficult and unpredictable to control the cycle especially in donor egg cycle.
2. External hormone preparation : most popular and easier to control cycle. There are 3 routes of medication : Oral, Transdermal and vaginal medication has been using in Thailand. The result has not depended on the routes of taking.
3. Stimulated preparation : Some doctors are using Clomiphene citrate, Aromatase Inhibitor or FSH/HMG to stimulate the eggs for increase the endometrial thickness. We need to think about the cost-effectiveness for this way. It would be the last choice to do if some patients fail from other methods.
