IVM – In Vitro Maturation Of Oocytes
In
Vitro Maturation (IVM): A Breakthrough in Assisted Reproduction
IVM stands as a cutting-edge technique in
assisted reproduction. Unlike traditional IVF, where women receive multiple
hormonal injections to yield more eggs, IVM takes a different approach. It
involves collecting immature eggs, maturing them in a laboratory setting, and
subsequently subjecting them to IVF.
IVM
boasts several advantages over IVF, primarily due to its reduced or sometimes
eliminated need for medications:
- Cost-Effective: IVM is
notably more budget-friendly.
- Convenience: It offers
greater convenience as it minimizes the necessity for frequent hospital visits.
- Reduced Stress and Side
Effects: IVM significantly lowers emotional stress and side effects for women.
Initially designed to address the needs of PCOS/PCOD patients by
avoiding excessive hormonal stimulation and OHSS, IVM has demonstrated its
utility in various scenarios. This includes cases with abnormally high
responses to gonadotrophin stimulation, patients with poor responses, those
involved in fertility preservation, oocyte donation programs, and
Pre-Implantation Genetic Screening (PGS) initiatives.
IVM
has shown promising results, with pregnancy rates averaging around 30-35% per
cycle. It presents itself as a viable alternative to traditional IVF for
infertile patients with a high number of antral follicles or an elevated risk
of developing OHSS.
FAQ
IVM is a technique in which immature eggs (oocytes) are collected from a woman's ovaries and then matured in a controlled laboratory environment. This is typically done for women with certain fertility issues or in specific IVF protocols.
IVM is used for various reasons, including in cases where a woman has polycystic ovary syndrome (PCOS), a high risk of ovarian hyperstimulation syndrome (OHSS), or when the patient prefers to avoid the hormonal stimulation that traditional IVF requires.
In traditional IVF, fully mature eggs are collected after hormonal stimulation of the ovaries. In IVM, immature eggs are collected without extensive hormonal stimulation and are matured in vitro. IVM typically involves fewer or no ovarian stimulation injections.
Suitable candidates for IVM are often women with PCOS, those at risk of OHSS, or those who prefer a more natural and less hormone-intensive approach to IVF. A fertility specialist will determine if IVM is appropriate based on individual circumstances.
Immature oocytes are collected from the ovaries using a transvaginal ultrasound-guided aspiration procedure, which is similar to the egg retrieval process in traditional IVF.
After collection, immature oocytes are cultured in a special medium in a laboratory incubator for a period of time, typically 24-48 hours, to allow them to mature.
Once the oocytes have matured in vitro, they can be fertilized using either conventional IVF (with sperm) or intracytoplasmic sperm injection (ICSI), depending on the specific case.
Success rates for IVM can be lower than those of traditional IVF, especially in terms of live birth rates. The outcome depends on factors such as the woman's age, the reason for IVM, and the specific clinic's expertise.
While IVM is generally considered safe, it may carry certain risks, including a lower success rate compared to traditional IVF. There's also a risk of egg damage during the IVM process.
IVM is offered by some fertility clinics, but it may not be as widely available as traditional IVF. If you're interested in IVM, you should consult with a fertility specialist to determine if it's an option at your chosen clinic.
