Embryo freezing

General Information

Embryo freezing is a fertility freezing technique where the embryo formed by combining the eggs and the sperms are preserved. These embryos can be inseminated whenever the couple is ready to start their family through the IVF process. In embryo freezing, both male and female participation is needed. 

‘’The first successful pregnancy resulting from freezing the embryo took place in the 1980s’’.

The main goal of freezing embryos is to preserve them for later use. The benefits contain- the alternative to have frozen embryos thawed and transferred to a woman’s uterus in the future without having to undergo stimulation of the ovaries or egg retrieval. With the use of embryo freezing technique, the embryo transfer process will be done without repeating all the steps of in-vitro fertilization. Just transfer the embryo after the physical examination and examining the uterus lining. Another benefit of embryo freezing is that it allows genetic testing.

‘’A person may decide to store an embryo if they hope to become pregnant in the future or also they can decide to donate to others, or donate for medical research.’’

Embryo Freezing Process

The process starts by using hormones and other medications to stimulate the production of potentially fertile eggs. A doctor then extracts the eggs from the ovaries (using an ultrasound machine to ensure accuracy), either for fertilizing in a laboratory of for freezing. Before freezing can take place, suitable embryos should be created. To do so in the laboratory, doctors must harvest and fertilize a few eggs.

Who can benefit from Embryo freezing?

  • Same-sex couples and other LGBTQ people who wish to have children
  • People who take medications that affect fertility
  • People with genetic disorders that affect reproduction
  • People who will soon undergo chemotherapy
  • People who are approaching an advanced reproductive age and who are not ready to have children
  • People who suffer from Ovarian Hyper Stimulation Syndrome (OHSS)
  • People who are already undergoing IVF or ICSI treatments and would like an option to use the extra embryo if the first IVF cycle was not successful

Freezing Methods

In this method the embryos are placed in sealed tubes, slowly lowering their temperature. It prevents the embryo’s cell from ageing and reduces the risk of any damage.

In this freezing method, the doctor freezes the cryoprotected embryos so quickly that the water molecules do not have time to form ice crystals. This helps protect the embryos and boosts their rate of survival during thawing.

After the process of freezing is complete, the doctor stores the embryos in liquid nitrogen until they are needed for future use.

Is it safe to use frozen embryos in treatment?

Yes. It is just as safe as using fresh embryos in the treatment.

Embryo Freezing Cost

The average embryo freezing cost for 6 months in India ranges from Rs.16758 to Rs. 71687.

Note – The cost will vary depending on your individual clinic.

Some facts regarding embryo freezing process

  • Embryos can be frozen at any stage from Day one and day six after egg retrieval
  • Better quality embryos have a better chance for future pregnancy success
  • It is not recommended to use embryos which have been frozen for more than 5 years
  • Couples can opt for preimplantation genetic diagnosis (PGD) to test embryos for genetic abnormalities

How long can embryos stay frozen?

A correct frozen embryo can remain viable for any length of time. There are examples of successful and healthy pregnancies resulting from eggs that people have stored for up to 10 years.

Embryo Freezing Success rates

Patients who use frozen embryos currently experience success rates equal to, or greater than, those from fresh embryo transfer cycles. The success rate for IVF using frozen embryos has been increasing year on year. The birth rate for frozen embryo and thawed embryos was 39 per cent, compared to 20 per cent for fresh embryos.

Side effects of Embryo Freezing

Side effects of embryo freezing generally occur when the doctor is extracting the eggs. The side effects tend to be very mild and temporary. They include- cramping, bloating, feeling full, infection, changes in the vaginal discharge, slight bleeding.

Embryo Freezing related FAQs

What is embryo freezing?

Embryo freezing, also known as embryo cryopreservation, is a process of preserving embryos by freezing them at a very low temperature, typically -196°C, for later use in fertility treatment.

How is embryo freezing done?

Embryo freezing typically involves first performing an IVF cycle to produce embryos, then selecting the highest quality embryos for freezing. The embryos are then slowly cooled and stored in liquid nitrogen.

How long can embryos be frozen?

Embryos can be frozen for several years or even decades, with some reports suggesting that embryos have been successfully thawed and used in fertility treatment up to 30 years after they were frozen.

What is the success rate of using frozen embryos in fertility treatment?

Success rates can vary depending on factors such as the age and health of the woman and the quality of the embryos, but using frozen embryos in fertility treatment can be just as successful as using fresh embryos.

How much does embryo freezing cost in Mumbai?

The cost of embryo freezing in Mumbai can vary depending on the clinic and the individual's needs, but typically ranges from several tens of thousands to over a hundred thousand rupees.

What are the risks associated with embryo freezing?

The risks of embryo freezing are generally low, but can include potential damage to the embryos during the freezing or thawing process.

Can frozen embryos be used in other clinics or countries?

Yes, frozen embryos can often be transferred between clinics or even between countries, although the process can involve additional legal and logistical considerations.

How can I prepare for embryo freezing?

Preparing for embryo freezing typically involves following a similar protocol as for IVF treatment, including taking medications to stimulate the ovaries and monitoring the growth of the eggs.

What should I expect after embryo freezing?

After embryo freezing, individuals may experience side effects such as cramping or spotting, and will typically need to wait until they are ready to use the embryos in fertility treatment before undergoing the embryo transfer procedure.
