Egg, Sperm, and Embryo Freezing in Iran are currently being performed in a number of fertility centers and clinics in Iran. The highly specialized medical team, state-of-the-art equipment, and affordable prices are all some reasons for which, many people from across the globe have chosen Iran for their medical and aesthetic treatments.
What is Egg, Sperm, and Embryo Freezing?
The technique of cold preservation or cryopreservation makes it possible to preserve eggs, sperm, and embryos for several years for future use.
Sperm Freezing in Iran
It has been years now since freezing sperms in Iran have helped many to retain their fertility for a longer period. There are many reasons for which men might tend to freezing sperm technique. In order to preserve fertility, a man may alternative to freezing sperm. For example, if somebody is going through chemotherapy, the sperms are at definite harm. Radiation can be as harmful to the sperms as chemotherapy. In these cases, before starting any treatment, a freezing of the sperm can be planned and applied. If after his chemotherapy or radiotherapy treatment, the patient is no longer able to produce healthy sperm, the frozen samples will be used to perform fertility methods such as IVF (in vitro fertilization) or IUI (intrauterine insemination).
Egg freezing in Iran
Women all around the world normally become less productive in terms of oocyte production from the age of 35. On the other hand, many women have healthy oocytes but are not ready to become mothers and tend to save their eggs for the future use.
One of the ways to preserve fertility is to store ovarian tissues or their oocytes (immature or mature) to fertilize them and reinject them respectively in the future. Vitrification of oocytes is said to be the easiest and most efficient method for preserving fertility for women. Cryopreservation of mature oocytes can be performed as an alternative to freezing embryos.
During the IVF, if the number of embryos obtained is greater than the number of embryos transferred, the supernumerary embryos can be frozen; provided they are healthy and of very good quality.
Previously, all embryos developed during IVF had to be immediately implanted in the mother's uterus. The new law allows only one to be implanted and the others to be frozen. It consists of immersing the embryos in liquid nitrogen at -196 °C. The temperature drop is extremely rapid and makes it possible to obtain an almost instantaneous vitreous state of the embryos. Thus preserved, the embryos can be transferred later into the uterus, without having to go through the stages of egg retrieval and fertilization again.
In any case, a new IVF attempt will not be made as long as there are frozen embryos left.
