"Collect" eggs to improve In vitro fertilization (IVF) success rates (2024)

The method of egg freezing is gaining popularity among women, particularly when they want to delay childbirth for personal reasons or have incurable diseases that require treatment, which can affect their future fertility.

Egg freezing boosts IVF success rates

At Vinmec Fertility Center, the method of egg freezing is chosen for treatment by infertile couples whose wives have reduced ovarian reserve, in order to increase the chances of success in IVF.

S. and her husband (a foreigner born in 1987) have been attempting IVF for three years with no success. When she arrived at Vinmec, doctors at Vinmec Fertility Support Center diagnosed her with premature ovarian failure and decreased ovarian reserve, which meant her chances of success were slim. Doctors did, however, offer her a treatment option: instead of IVF immediately following egg retrieval, the eggs would be frozen. You will have "a fair amount" of eggs after "gathering" so many times to confidently embark on an IVF cycle.

Doctors monitored Ms. S. and aspirated eggs during the natural cycle and placed them in the laboratory to freeze eggs. Ms. S. and her husband were overjoyed after nearly a year of perseverance when she finally had "2 lines." In addition, she freezes 3-embryo eggs for "savings." She is 15 weeks pregnant, the fetus is developing normally, and the mother is resting and anticipating the day of "blooming and pistil."

"At Vinmec, the doctors and technicians who directly handle egg freezing have been thoroughly trained at the leading local and international Reproductive Support Centers to carry out the process smoothly," stated MSc. Dr. Le Thi Phuong Lan, who is in head of the fertility support lab. As a result, Vinmec successfully defrosts eggs at a rate of 95–98%. After thawing, the quality of the embryos produced from fertilized eggs was identical to that of unfrozen eggs. In situations like Ms. S., we therefore suggest embryo preservation as the most expedient and least expensive option rather than harvesting eggs and performing IVF multiple times.

Currently, sperm, embryos, and eggs are all frozen by Vinmec using the vitrification process. The quick freezing period and lack of ice crystal development inside the cells provide this technology a significant edge over traditional procedures. Oocytes are thus more safely preserved, and when they are thawed, they will have a high rate of survival. This is one of the current safest and most effective techniques for cryopreserving eggs, embryos, and sperm.

Leading fertility clinics in Vietnam and other nations including Japan, Korea, Canada, and Singapore use this egg freezing technique. In particular, utilizing the vitrification process, Vinmec also successfully preserved egg tissue at the end of 2017 for a 19-year-old girlfriend who had endometrial cancer.

After the age of 35, the quality of a woman's eggs declines. In particular, in mothers after the age of 40, the quality of the embryos conceived is low, the rate of abnormal pregnancy is high. Successful egg storage opens the door to preserving reproductive function in many cases. As someone who has been in contact with many women who come to Vinmec to store eggs, Dr. Le Thi Phuong Lan shared: “Egg storage is not only a good treatment solution when you have health problems: Having to undergo chemotherapy treatment, radiation therapy and still want to have children afterwards; you have ovarian failure, decreased ovarian reserve. However, in the current trend of late marriage, at a certain age that has not yet chosen a soulmate, egg storage has also been interested, researched and "decided" by many women. This gives birth to healthy babies with frozen eggs. If you are thinking about this issue, you can consult with Vinmec doctors so that you can make timely decisions, ensuring a good start for your baby's health in the future.

Process of freezing eggs at Vinmec

• Advising clients on egg freezing techniques. A lady must first have "eggs" in order to freeze her eggs. The quality of eggs starts to deteriorate around the age of 35, and infants who are born from older mothers' eggs are more likely to experience chromosomal alterations. Therefore, egg freezing should be done before this age, barring circ*mstances when there is a diminished ovarian reserve.
• Utilizing ovarian stimulant medications
• Egg aspiration: Before aspiration, the woman is given local anesthesia or anesthesia depending on the doctor's prescription.
• The oocytes are inspected for quality, mature oocytes are chosen, and they are then vitrified and placed in a particular ovulatory environment. Then, the frozen oocytes were kept in liquid nitrogen for a protracted period of time at a very low temperature of -196 degrees Celsius.

Note:

If the anesthetic approach permits, this procedure can be used on people who have thrombotic diseases or major chronic medical conditions such heart failure, liver failure, renal failure, or blood clotting disorders. The treating physician will carefully evaluate and consult the patient in situations of gynecological cancer before deciding on the best course of action.
