What is Egg Freezing?
Egg freezing, medically known as mature oocyte cryopreservation, is a fertility preservation technique in which a woman's eggs are collected, frozen, and stored for possible future pregnancy.
According to Dr. Akanksha Goel, Fertility Specialist at Nova IVF Fertility, Kolkata, the process usually begins with hormonal injections that stimulate the ovaries to produce multiple mature eggs during a single menstrual cycle. Once the eggs mature, they are retrieved through a minimally invasive procedure and frozen using a rapid-freezing technique called vitrification, which helps preserve egg quality.
Dr. Goel noted that while egg freezing was initially developed for women undergoing cancer treatment or medical therapies that could affect fertility, it is now increasingly being chosen for personal and social reasons as well. However, she stressed that the procedure should not be viewed as a guaranteed 'insurance policy' for pregnancy. “Egg freezing can expand future reproductive options, but success depends on factors such as the age at which the eggs are frozen and the overall reproductive health of the individual,” she added.
Why Are More Women Choosing Egg Freezing?
Dr. Goel said that many women today are opting for egg freezing due to a combination of personal, professional, and medical reasons. Delayed motherhood, linked to career goals, financial stability, higher education, or not having found the right partner, are among the most common reasons driving interest in fertility preservation.
At the same time, awareness about age-related fertility decline has increased significantly, encouraging women to explore ways to preserve their reproductive choices. On the medical side, she noted that egg freezing is often recommended for women undergoing chemotherapy, radiation, ovarian surgeries, or those diagnosed with conditions such as endometriosis or autoimmune disorders that may affect ovarian reserve. According to her, there is also a broader shift toward reproductive autonomy, where women increasingly see fertility preservation as a proactive decision rather than a last resort.
What is the Ideal Age to Freeze Eggs?
According to Dr. Goel, the ideal time for egg freezing is generally during the late 20s to early 30s, when both egg quality and ovarian reserve are considered to be at their best. Fertility naturally declines with age, especially after 35, due to a reduction in both the number and quality of eggs.
“Freezing eggs at a younger age can improve the chances of preserving healthier eggs and may lead to better pregnancy outcomes in the future,” she said. However, she emphasized that the decision should remain highly individualised and based on factors such as personal goals, medical history, and ovarian reserve testing. Dr. Goel added that doctors often recommend fertility assessments such as Anti-Müllerian Hormone (AMH) testing and antral follicle count scans before making a decision. While egg freezing can still be performed after 35, she noted that women may require multiple cycles to retrieve an adequate number of healthy eggs, and overall success rates may gradually decline with increasing age.
Procedure, Pain, and the Cost Involved
Dr. Goel explained that the egg-freezing process typically starts with fertility evaluations, including hormone testing and ultrasound scans. This is followed by around 10 to 12 days of hormonal injections that stimulate the ovaries to produce multiple mature eggs instead of the single egg normally released during a menstrual cycle. Doctors monitor follicle growth closely through blood tests and ultrasounds throughout the process.
“When the eggs are ready, a trigger injection is given for final maturation, following which the eggs are retrieved under light sedation using an ultrasound-guided needle,” she explained. The mature eggs are then immediately frozen using vitrification technology and stored in specialised cryogenic tanks. She described the procedure as minimally invasive, adding that most women can resume normal daily activities within one or two days, although mild bloating or temporary discomfort may occur.
Talking about costs, Dr. Goel said that a single egg-freezing cycle in India may range between Rs 1.5 lakh and Rs 3 lakh or more, depending on factors such as the clinic, medications used, city, and the number of cycles required. She added that additional expenses may include fertility tests, hormonal injections, storage charges, and future IVF procedures when the eggs are eventually used. “Women with lower ovarian reserve or those freezing eggs at an older age may require multiple cycles, which can significantly increase the overall cost,” she said. Dr. Goel reiterated that while egg freezing offers reproductive flexibility, realistic counselling remains important.
Does Egg Freezing Guarantee a Future Pregnancy?
According to Dr. Amitha N, Consultant – Fertility & IVF Specialist at Motherhood Fertility & IVF, Electronic City, Bengaluru, egg freezing is an important advancement in reproductive medicine, but “it should not be viewed as a guaranteed pathway to pregnancy.”
She explained that after eggs are frozen, they still need to survive the thawing process, get successfully fertilised, implant in the uterus, and develop into a healthy pregnancy - each stage carrying its own challenges. “Egg freezing preserves the possibility of pregnancy, not a promise of a future baby,” she said.
