What is Embryo Freezing and Selection? Heres What Couples Need to Know About Modern IVF Labs

Understand the latest advancements in IVF technology! Know about embryo freezing, selection, and the role of modern IVF labs in improving success rates and building a family.

Parenthood is today defined by personal timelines, medical options, and lifestyle preferences. With a growing number of Indian couples seeking fertility treatments, in vitro fertilisation (IVF) is becoming a reliable and accessible choice, not just in metros but also in Tier 2 and 3 cities.

It’s not just access that’s evolving but science as well. With the advent of cutting-edge technology, well-equipped embryology labs, and qualified experts, IVF results are improving consistently. But as options increase, it’s more important than ever to be aware of the nuances of the process and know what to look for in an IVF lab. Here are some of the key components that modern, high-quality IVF labs must provide:

What is Embryo Freezing?

“Embryo freezing, or cryopreservation, is a process of freezing and storing fertilised eggs for later use. In this process, the embryos are rapidly frozen to sub-zero temperatures using the vitrification process, which prevents the formation of ice crystals and preserves the integrity of the cells for future implantation,” explains Dr Prachi Benara, fertility specialist at Birla Fertility & IVF, Gurgaon. The process improves an embryo’s viability by 90 95% post-thaw.

Egg freezing proves to be an excellent treatment option for those looking to preserve fertility and delay parenthood for personal, professional, financial, or medical reasons. Patients battling cancer, endometriosis, or autoimmune conditions may impact the quality and quantity of eggs and sperm, and freezing eggs, sperm, or embryos at a given point in time preserves fertility of that moment and may lead to successful implantation and pregnancy later.

What is Embryo Selection?

According to the doctor, availability of advanced embryo selection technology can help to pick the best embryos with the potential of a higher success rate. In the normal IVF process, the embryos are usually examined under the microscope for any visible abnormalities before transferring them to the uterus. Modern labs in India are going beyond this with tools like time-lapse imaging, artificial intelligence (AI), and preimplantation genetic testing (PGT), allowing couples to choose high-quality embryos for later use.

Time-lapse imaging delivers detailed information about what is going on with thousands of pictures continuously recording the process in embryos, whereas AI grading is faster and more accurate than the human eye in analysing morphological and developmental data. The screening of embryos before transfer using PGT helps to detect genetic problems; hence, it lowers the occurrence of miscarriage and chances of becoming pregnant.

Air Purification Systems

Given the worrying rate at which the air quality levels of several towns and cities of India have dropped, air quality has become the most crucial component of IVF labs. In the selection of the suitable IVF lab, couples should consider clinics that have state-of-the-art facilities complete with high-level air filtration systems, which include HEPA-filtered air systems. Air purification systems remove pollutants and keep the environment sterile, thus reducing the chances of contamination and other negative effects on embryo development. Experiments indicate that ideal laboratory air quality may raise the quality of embryos by 15-20 per cent and enhance success by as much as 10 per cent.

Micromanipulators

In IVF, special precision instrumentation is required to hold and manipulate gametes and embryos using microscope magnifications; in this case, a micromanipulator. They are mostly useful in the cases of such methodology as ICSI (Intracytoplasmic Sperm Injection), when the single sperm is inserted directly into the egg. The tool enables the embryologists to work on a microscopic level with precision. In line with IVF, micromanipulators are more controllable to place the egg and the sperm without causing little damage, thus enhancing the success of fertilisation.

Along with choosing the right lab, equipped with advanced technologies, couples must also look for fertility professionals with extensive expertise in the domain and the success rate of the clinic. The equipment alone does not determine the success of an IVF cycle, but a combination of factors together helps in achieving a successful outcome.
