Egg Freezing (Oocyte Cryopreservation)

Siam Fertility Clinic uses the latest freezing method called Vitrification which is the process of converting the oocytes into a glass-like solid under ultra low temperatures. The oocytes will be rapidly cooled until they harden like glass without any ice crystals forming.

In the embryology world, this method is important because ice crystal formation can do damage to frozen oocytes by reducing their viability.



In the process of Intracytoplasmic Sperm Injection (ICSI) fertilization, single sperm will be inject directly to single oocyte for solving sperm motility problem and increasing fertilization rate.


Nowadays, Frozen Embryo Transfer or FET is suggested for IVF/ICSI treatment as providing more pregnancy rate than FRESH embryo transfer.


IVF refers to a technique of assisted reproduction where the egg and sperm are fertilized outside of the body to form an embryo. This embryo is then transferred to the uterus to implant and become a pregnancy.

Operated by an expert infertility treatment with more than a decade of experience.
