Further to your enquiry, please note that Gender selection is illegal in Thailand. What we can offer to you is to do ICSI PGS FISH or aCGH for aneuploidy screening program.
This PGS aCGH or FISH will be able to let you know gender of your embryos and other chromosomes as well, in order to put most healthy embryo back into your womb and result in a healthy pregnancy.
By doing this, we will not be able to show you officially gender of embryos but will allow you to see the report and let you choose prefer embryo for transfer then freeze the rest of healthy embryos for future use.
