Treatment Overview
Minimal Stimulation IVF (also known as Mini-IVF or Mild IVF) is a gentler approach to in vitro fertilization designed to achieve pregnancy with minimal use of fertility medications. Unlike conventional IVF, which relies on high-dose hormonal stimulation to produce multiple eggs, minimal stimulation IVF uses lower doses of fertility drugs—or sometimes only oral medications—to encourage the development of one to three high-quality eggs.
In Korea, fertility clinics have refined this method using AI-guided ovulation prediction, hormone-level tracking, and precision ultrasound monitoring, ensuring optimal timing and results. The approach focuses on the natural physiology of the menstrual cycle, offering a more comfortable, safer, and cost-effective IVF alternative with fewer side effects and excellent success rates for selected patients.
Purpose & Benefits
The purpose of Minimal Stimulation IVF is to balance fertility success with patient comfort and safety. By using low-dose medications or natural hormonal cycles, this approach aims to produce fewer but higher-quality eggs while avoiding excessive stimulation.
Key benefits include:
- Reduced medication use and fewer injections.
- Lower risk of ovarian hyperstimulation syndrome (OHSS).
- Gentler on the body and less emotionally stressful.
- Improved egg quality due to physiological stimulation.
- Lower cost compared to full-stimulation IVF.
- More natural and repeatable cycles.
- Suitable for patients preferring less invasive treatment.
Korean fertility centers combine advanced imaging, hormonal analytics, and individualized planning to make minimal stimulation IVF both safe and highly effective.
Ideal Candidates
Minimal Stimulation IVF in Korea is ideal for:
- Women under 38–40 years old with good ovarian reserve.
- Patients who prefer low medication exposure or natural fertility approaches.
- Women with regular menstrual cycles and predictable ovulation.
- Couples with mild male-factor infertility or unexplained infertility.
- Women who experienced overstimulation or discomfort during previous IVF cycles.
- First-time fertility patients seeking a balanced, low-intensity entry into assisted reproduction.
It can also be an excellent option for women who want a gentler experience or who have ethical or personal preferences for minimal medical intervention.
Possible Risks & Complications
Minimal stimulation IVF is one of the safest fertility procedures available. However, some mild or temporary risks can occur, including:
- Temporary bloating or mild pelvic discomfort.
- Emotional stress or anxiety during cycle monitoring.
- Rare development of ovarian cysts due to hormonal fluctuations.
- Lower egg yield compared to conventional IVF (1–3 eggs per cycle).
Korean fertility clinics mitigate these risks with real-time ultrasound tracking, hormone testing, and personalized medication adjustments, ensuring optimal results while maintaining patient comfort and safety.
Surgical Techniques Used
Although minimal stimulation IVF does not involve surgery, it includes several precise clinical and laboratory procedures. Korean fertility centers are known for their use of advanced reproductive technologies and minimal-invasive methods that optimize outcomes with low medication use.
Techniques commonly used:
- Mild Ovarian Stimulation: Low-dose injectable hormones or oral medications like Clomiphene Citrate or Letrozole.
- Follicular Monitoring: Frequent ultrasounds and hormone tests to monitor egg development.
- Egg Retrieval (Oocyte Aspiration): A minimally invasive, ultrasound-guided procedure performed under mild sedation.
- Intracytoplasmic Sperm Injection (ICSI): Used when necessary to enhance fertilization.
- Embryo Culture: Advanced laboratory environments support embryo development to the blastocyst stage.
- Time-Lapse Imaging: Non-invasive embryo observation to select the highest-quality embryo for transfer.
- Ultrasound-Guided Embryo Transfer: Ensures gentle and accurate placement into the uterus.
Korean fertility laboratories maintain ISO-certified, xeno-free culture environments, ensuring top-tier embryo care with world-class precision.
Recovery & Aftercare
Recovery following minimal stimulation IVF is quick and uncomplicated. Patients typically return to their normal routines within 24 hours after egg retrieval or embryo transfer.
Typical aftercare involves:
- Rest for a few hours after egg retrieval or transfer.
- Avoiding strenuous activity for 1–2 days.
- Taking prescribed luteal phase support medications (such as progesterone).
- Staying hydrated and maintaining a balanced diet.
- Returning for follow-up blood or ultrasound tests to confirm pregnancy.
Korean fertility centers also provide holistic aftercare options such as nutritional counseling, relaxation therapies, and stress management programs to improve implantation and emotional well-being.
Results & Longevity
Minimal Stimulation IVF has demonstrated high success rates for appropriately selected patients. The goal is to produce fewer, but genetically healthier, eggs, leading to strong embryo development and improved implantation rates.
Typical outcomes in Korea:
- Pregnancy success rate per cycle: 30–45% for women under 35.
- Cumulative success rate (3–4 cycles): 50–65%.
- Reduced multiple pregnancy risk (<5%) due to limited follicle growth.
- Comparable live birth rates to conventional IVF in well-selected patients.
Korean fertility specialists use advanced monitoring systems, genetic testing, and high-precision timing to maintain consistently strong results while ensuring patient safety and comfort.
Treatment Process in Korea
Korea’s fertility clinics have standardized Minimal Stimulation IVF protocols that combine medical precision with patient-centered care.
Typical treatment flow:
Initial Consultation & Testing
A complete fertility assessment including hormone panels, ultrasound, and semen analysis to design a customized low-dose protocol.
Mild Ovarian Stimulation (Days 3–10)
Low doses of oral or injectable medications promote natural follicle development. Clinics use AI-assisted hormone monitoring for precise medication timing.
Monitoring & Ovulation Trigger
Regular ultrasounds and blood tests ensure follicles mature properly. Once ready, an hCG or GnRH agonist injection triggers ovulation.
Egg Retrieval & Fertilization
Eggs are retrieved 36 hours after the trigger. Fertilization is achieved via IVF or ICSI depending on the sperm quality.
Embryo Culture & Transfer
Embryos are cultured under advanced conditions and transferred on day 3 or day 5 (blastocyst stage) using ultrasound guidance.
Luteal Support & Pregnancy Testing
Progesterone therapy supports implantation. Pregnancy is confirmed via blood test after 10–14 days.
