In-vitro maturation, or IVM, is a form of assisted reproductive technology (ART) that allows for the collection of immature eggs from a woman without the use of hormonal injections to induce maturation. During this process, immature eggs are retrieved through a minor surgical procedure and then matured in a controlled environment using hormones or a naturally occurring protein called cumulin. Once the eggs are matured, they are typically fertilized using a method known as intracytoplasmic sperm injection (ICSI). After fertilization, the developing embryos are transferred into the woman’s uterus, and the waiting begins to see if pregnancy occurs.
IVM has been around since the 1990s, but its uptake has been limited due to the higher success rates associated with in-vitro fertilization (IVF). However, researchers like Dr. Emily Carter from the University of Queensland are making significant advancements in the IVM technique, which may soon make it a more viable alternative.
The Evolution of IVM Procedures
The main difference between older and newer IVM techniques lies in how the immature eggs are matured. The traditional method relied on hormonal stimulation, resulting in lower quality matured eggs. In contrast, the new method utilizes cumulin, a protein dimer that aids in egg maturation by interacting with the eggs’ supporting cells. Along with cyclic-AMP (c-AMP) modulators, this combination has shown the potential to increase the number of healthy mature oocytes produced by 50%.
One problem with the previous IVM approach was the generally poor quality of mature eggs compared to those obtained via IVF. The innovative use of cumulin and c-AMP could address these issues, providing a more effective solution.
Comparing IVM and IVF
IVF requires women to undergo multiple hormonal injections to stimulate egg maturation while still in the ovaries. In contrast, IVM allows for the maturation of eggs post-retrieval, eliminating the need for extensive hormonal treatment. This is particularly beneficial for women with conditions like polycystic ovarian syndrome (PCOS), those with other reproductive challenges, or individuals recovering from cancer who may experience adverse effects from hormone therapy.
While IVF patients usually endure a series of hormone injections, ultrasounds, and blood tests, IVM needs far fewer medical interventions. The new IVM method may only require a couple of blood tests and transvaginal ultrasounds within a week, with hormone doses reduced by 90%. This significantly lowers the overall cost when compared to IVF.
Steps Involved in the IVM Process
- Initial Testing: Ultrasounds and blood tests help determine the optimal time for egg retrieval. Some women may take small doses of hormones beforehand, typically in pill or suppository form.
- Egg Retrieval: Immature eggs are collected through a minor surgical procedure guided by ultrasound. Medication is administered to minimize discomfort.
- Maturation: In the old method, immature eggs were placed in culture and stimulated with hormones. The new method uses cumulin and c-AMP for maturation, both taking around 24-48 hours.
- Fertilization: ICSI is often employed to fertilize the matured eggs, with a single sperm injected into each egg.
- Embryo Transfer: The doctor transfers one to four embryos into the woman’s uterus, followed by a short wait of less than 12 days to check for successful implantation.
- Follow-Up: If successful, care is transitioned to an OB/GYN. If not, the couple may opt for another IVM cycle.
