Application and Evaluation of IVM (In Vitro Maturation) of Immature Oocytes in Georgia

What is IVM Technology in Georgia? Direct Answer

IVM (In Vitro Maturation) technology refers to the retrieval of immature oocytes at the germinal vesicle (GV) stage or metaphase I (MI) stage from small antral follicles in the ovary, without or with only minimal use of ovarian stimulation drugs. These oocytes are cultured in a special laboratory medium for 24-48 hours to develop to metaphase II (MII) stage, after which conventional in vitro fertilization or intracytoplasmic sperm injection (ICSI) is performed. Some reproductive centers in Georgia have implemented IVM technology as an alternative to conventional IVF, particularly for specific patient groups.

Why is IVM Technology Needed? The Doctor's Perspective

Conventional IVF requires ovarian stimulation with high doses of gonadotropins, posing a risk of Ovarian Hyperstimulation Syndrome (OHSS), especially for patients with Polycystic Ovary Syndrome (PCOS). IVM technology can almost eliminate the risk of OHSS by avoiding or reducing the use of stimulation drugs, while also lowering medication costs and the number of injections. From a reproductive specialist's perspective, IVM is suitable for:
· PCOS with arrested follicle development or excessive small follicles
· Previous severe OHSS from stimulation treatments
· Poor response to stimulation drugs (e.g., diminished ovarian reserve but with some antral follicles remaining)
· Hormone-dependent tumors (e.g., estrogen receptor-positive breast cancer) where high estrogen environments must be avoided
· Patient's personal choice to avoid stimulation medications

However, doctors clarify: IVM is not a universal solution. Maturation rates in conventional IVF are typically 85%-90%, whereas IVM maturation rates are only 60%-75%. Fertilization and blastocyst formation rates are generally lower than in conventional IVF. Therefore, clinical decision-making requires weighing the pros and cons.

IVM Differences Across Age Groups

Age directly impacts oocyte quality and is closely related to IVM outcomes:
· Under 35 years: Higher initial oocyte quality, relatively good developmental potential even after in vitro maturation. Live birth rates can approach 60%-70% of conventional IVF (depending on lab conditions).
· 35-40 years: Increased risk of oocyte aging, significantly lower success rates for in vitro maturation of immature eggs, maturation rate may fall below 50%, and good quality embryo rate decreases. Doctors typically recommend mild stimulation or conventional stimulation first, considering IVM only after repeated failure or high OHSS risk.
· Over 40 years: IVM is not recommended as a first choice. At this age, oocyte quantity is limited and aneuploidy rates are significantly higher. Maturation, fertilization, and pregnancy rates with IVM are far lower than conventional IVF, offering minimal clinical benefit.

Actual Process of IVM in Georgia

Undergoing IVM treatment in Georgia involves the following steps:
1. Initial Assessment: Hormonal tests (AMH, FSH, LH, E2), vaginal ultrasound (antral follicle count, ruling out ovarian cysts), infection screening, chromosomal karyotype analysis.
2. Cycle Preparation: No or only short-term ovarian stimulation (e.g., low-dose FSH for 3-5 days), or monitoring follicle growth in a natural cycle. When the dominant follicle reaches 10-14mm in diameter, an HCG trigger is administered, and egg retrieval occurs approximately 36 hours later.
3. Egg Retrieval Surgery: Under intravenous anesthesia, small follicles (diameter <10mm) are punctured via transvaginal ultrasound guidance to aspirate follicular fluid. A finer needle is typically used to retrieve immature oocytes. The procedure takes about 15-30 minutes.
4. In Vitro Culture: In the lab, immature oocytes are transferred to a special IVM culture medium containing specific hormones and growth factors. They are cultured in an incubator with 5% O2 and 6% CO2 for 24-48 hours. Oocyte maturation is monitored periodically, recording the proportions of GV, MI, and MII stages.
5. Fertilization and Embryo Culture: Once the oocyte extrudes the first polar body (MII stage), ICSI is performed for fertilization. Embryos are cultured further to the cleavage or blastocyst stage. If many oocytes are retrieved, PGT-A screening may be performed (additional cost).
6. Embryo Transfer: Fresh transfer is possible (if endometrial conditions are suitable), but most centers opt for freezing all embryos for transfer in a subsequent natural or artificial cycle to improve implantation rates.

How Long Does IVM in Georgia Take? Timeline

The duration of a complete IVM cycle is as follows:
· Assessment phase: 1-2 days (initial consultation, ultrasound, blood tests)
· Pre-retrieval preparation: 2-5 days (very short stimulation or natural monitoring)
· Egg retrieval surgery: Half a day (can be discharged the same day)
· In vitro culture: 1-2 days
· Fertilization and embryo culture: 2-6 days (depending on transfer plan)
· Frozen cycle: After embryo freezing, the transfer cycle usually takes 2-4 weeks (depending on endometrial preparation protocol)
Overall, from starting medication to completing embryo transfer is about 1.5-2 months (including frozen embryo transfer). For a fresh transfer, the total time is approximately 15-20 days.

Cost Factors: How Much to Prepare for IVM in Georgia

The cost of IVM in Georgia mainly consists of the following:
· Medical Fees: Including doctor consultation, ultrasound monitoring, egg retrieval surgery, IVM culture, ICSI, embryo culture, and transfer. The cost of a standard IVM cycle is typically 80%-90% of conventional IVF (due to reduced stimulation drug costs), but laboratory costs are higher. Currently, the price for an IVM cycle in Georgia ranges from €4,500 to €6,500, depending on the center and whether it includes PGT, freezing, etc.
· Medication Costs: Very low, approximately €300-€800 (most cases do not require high-dose stimulation).
· Additional Costs: Such as embryo freezing (first year around €400-€600), PGT-A (approximately €250-€400 per embryo), multiple ultrasounds/blood tests.
· Accommodation and Travel: Requires a stay in Georgia of at least 10-14 days (before and after egg retrieval). Hotels, meals, and flights are at your own expense.
Key variables: Choice of hospital, whether using IVM plus mild stimulation, and whether blastocyst culture is performed.

Common Pitfalls: What Patients Need to Watch Out For

• Mistakenly believing IVM has the same success rate as conventional IVF: Many patients compare IVM data with IVF, ignoring laboratory differences. Only 2-3 centers in Georgia perform IVM, and culture systems and operator experience vary greatly. When choosing a center, request their data on maturation, fertilization, and blastocyst formation rates for IVM cycles over the past 1-2 years.
• Neglecting initial oocyte quality assessment: Even with IVM, patients over 38 years old or with AMH <1.2 ng/ml may have a proportion of MII oocytes below 40%, resulting in very few transferable embryos. Doctors should perform cumulus complex morphology scoring beforehand and adjust the plan if initial quality is poor.
• Rushing into fresh transfer: Endometrial synchrony is often suboptimal in IVM cycles because the culture period for immature oocytes can mismatch the implantation window with endometrial preparation. Pregnancy rates with fresh transfer are lower than with frozen embryo transfer; freezing all embryos and preparing the endometrium later is a more reliable choice.
• Ignoring the risk of chromosomal aneuploidy: The chromosome euploidy rate of oocytes obtained via IVM is slightly lower than that of naturally matured oocytes in vivo, especially in older women. PGT-A screening is recommended but adds cost and may lead to embryo loss.
• Thinking IVM can be chosen freely without assessing ovarian reserve: IVM offers clear advantages for PCOS patients, but for those with diminished ovarian function (e.g., low AMH, few antral follicles), the baseline number of oocytes retrieved is low, and it may even be impossible to obtain mature eggs. Blindly choosing IVM is not advisable.

When is IVM in Georgia Suitable?

When is it Not Suitable?

• Age ≥40 years with normal ovarian function may be considered, but clinical benefit is minimal; conventional stimulation or egg donation is preferred.
• Very poor ovarian reserve (AMH <0.5 ng/ml, total antral follicle count <5); low probability of obtaining immature oocytes, and IVM culture may yield no mature eggs.
• Definite endometrial factors (uterine adhesions, endometritis) or hydrosalpinx should be addressed first.
• Chromosomal abnormalities (e.g., balanced translocation) requiring PGT-SR: theoretically possible, but the number of embryos must be sufficient for biopsy.
• Severe male factor (e.g., azoospermia requiring testicular biopsy) with poor sperm quality; fertilization failure risk may be exacerbated with IVM.

Interpreting Test Indicators: How to Determine if IVM is Feasible

Reproductive specialists consider the following indicators to decide whether to proceed with IVM:
· AMH: >2.0 ng/ml usually suggests a polycystic tendency, suitable for IVM; <1.2 ng/ml requires caution.
· FSH: Basal FSH <10 mIU/ml is favorable; >15 mIU/ml indicates diminished ovarian reserve, poor IVM outcomes.
· Antral Follicle Count (AFC): Unilateral ≥12 or bilateral ≥20, predominantly small follicles (2-8mm), suitable for IVM.
· LH/FSH Ratio: >2.5 with PCOS phenotype, high likelihood of benefiting from IVM.
· Previous Ovarian Response: History of empty follicle syndrome or oocyte immaturity rate >50% should prompt consideration of IVM.

Practitioner Observation: Development and Limitations of IVM in Georgia

In Georgia, IVM technology is primarily used for PCOS patients or special cases requiring OHSS avoidance. Some centers, such as Chachava, Betaplus, and VIVO Reproductive Center, have IVM laboratory experience, but the number of procedures performed is far lower than in Europe (e.g., Japan, Belgium). Key laboratory points include:
· Culture medium composition (requires addition of FSH, HCG, EGF, etc.)
· Gas conditions (low oxygen culture at 5% O2 is superior to atmospheric oxygen)
· Culture duration (24-48h, determined by cumulus expansion)

Observed IVM maturation rates vary widely, roughly: 70%-80% in young PCOS patients, only 50%-60% in non-PCOS patients. The rate of embryo developmental arrest after fertilization is higher than for in vivo matured eggs. In Georgia, most doctors recommend IVM as a backup option rather than a first choice, unless there is a clear medical indication.

Risk Reminder: Potential Problems with IVM

• Unstable maturation rate: Some or all immature oocytes may fail to complete meiosis, resulting in no embryos for transfer.
• Reduced embryo quality: The in vitro culture environment cannot fully mimic the in vivo environment; mitochondrial function and epigenetic modifications may be affected, leading to lower blastocyst formation rates compared to conventional IVF.
• Chromosomal aneuploidy rate: Studies show a slightly higher mosaicism rate in embryos derived from IVM; PGT-A screening is recommended.
• Pregnancy rate after transfer: Cumulative live birth rates are typically 10%-20% lower than conventional IVF; patients should have realistic expectations.
• Lab dependency: Culture techniques vary significantly between centers without unified quality control standards; it is essential to review the center's IVM data from the past six months.

Doctor's Advice: How to Decide

• Prioritize a complete fertility assessment (AMH, AFC, hormone panel, thyroid function, vitamin D) to evaluate ovarian reserve and endocrine status.
• If PCOS with high OHSS risk is confirmed, IVM can be a first-line option; otherwise, consider it at least after conventional IVF failure or medication intolerance.
• When choosing a reproductive center in Georgia that performs IVM, request the center's data on maturation, fertilization, and clinical pregnancy rates for IVM cycles over the past 1-2 years, and inquire about culture conditions (e.g., use of Premix IVM medium or addition of FSH/HCG).
• If viable embryos are obtained after an IVM cycle, it is recommended to freeze all embryos and perform a frozen embryo transfer when endometrial synchrony is optimal to improve implantation rates.
• Ensure male partner screening is completed before IVM to avoid total embryo developmental failure due to sperm issues.
