Embryo Freezing Procedure

Embryo freezing is a specialized technique done at a fertility hospital in Hyderabad. One has access to such facilities in one of the best fertility hospitals in Hyderabad.

Embryo freezing is a procedure that does allow people to store embryos for later use. A person can also freeze eggs, which are not fertilized. Fertility hospital in Hyderabad has the required infrastructure for freezing eggs into embryos.

A person may indeed decide to store an embryo in case he or she hopes to become pregnant in the future, to donate to others, for medical research, or for training purposes.

The process does begin by making of hormones and other medications in order to stimulate the production of potentially fertile eggs. A doctor then tries to extract the eggs from the ovaries, either for fertilizing in a lab or for freezing purposes. Best fertility hospitals in Hyderabad do take care of such processes.

Embryo Freezing Procedure

Successful fertilization can indeed lead to at least one healthy embryo. A doctor then is able to transfer the embryo to the womb, or uterus. If the treatment happens to be a success, the embryo will develop.

Fertilization often does result in more than one embryo, and the doctor can then freeze and preserve the remaining embryos.

What is an embryo, and how do people create one?

Embryo freezing does enable people to have children at a later date.The term embryo is used from the moment the cells divide after fertilization until the eighth week of pregnancy. Fertility hospitals in Hyderabad can provide a requisite environment for embryo formation.

Before freezing starts to take place, people do need to create suitable embryos. In order to do so in the laboratory, doctors must harvest and fertilize some eggs.

First, the person will take hormones in order to make sure that ovulation does happen on schedule. They will then take fertility medications in order to increase the number of eggs that they produce.

In the hospital, a doctor tries to extract the eggs, making use of an ultrasound machine in order to ensure accuracy.

A person can hope to freeze their eggs. Or, in case they may wish to use them at once in order to become pregnant. In such a situation, the doctor can recommend in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).

During IVF, the doctor does expose the eggs to sperm and then leaves them in a laboratory for fertilization to take place. Then, the fertilized egg is referred to as an embryo.

An embryologist will rather monitor the development of the embryos over the next 6 days, after which they may choose a suitable embryo for implantation.

During ICSI, the doctor does extract the eggs and injects a single sperm directly into an egg.

They may do this in case of a problem with the sperm or if past attempts at IVF have not resulted in fertilization. The doctor may use one embryo and then freeze the others.

How do people freeze embryos?

The main purpose of freezing embryos is to preserve them for later use.The major challenge that is encountered is the water within the cells. When this water freezes, crystals tend to form and burst the cell.


In order to prevent this from happening, the doctor does make use of a process referred to as cryopreservation. It does involve replacing the water in the cell with a substance known as a cryoprotectant.

The doctor then tends to leave the embryos to incubate in increasing levels of cryoprotectant before freezing them.

After removing most of the water, the doctor tries to cool the embryo to its preservation state. They then use one of two freezing methods:

Slow freezing:

This does involve placing the embryos in sealed tubes, then slowly lowering their temperature. It does prevent the embryo’s cells from aging and reduces the risk of damage. However, slow freezing is time-consuming, and it does require expensive machinery.


In this process, the doctor does freeze the cryoprotected embryos so quickly that the water molecules do not have time to form ice crystals. This does help protect the embryos and increases their rate of survival during thawing.

After the process of freezing is complete, the doctor then stores the embryos in liquid nitrogen.
