Treatment Overview
Gonadotropin Ovulation Induction Therapy uses injectable gonadotropins (recombinant or urinary-derived FSH, LH, or human menopausal gonadotropin [hMG]) to stimulate the ovaries to produce one or more mature follicles, triggering ovulation. Unlike milder oral ovulation drugs (e.g. clomiphene, letrozole), gonadotropins act more directly and powerfully on the ovaries. In fertility treatment, this method is used for patients who either do not respond to first-line oral agents or who require more controlled, potent stimulation (e.g. for IUI or as part of IVF stimulation).
In Korea, fertility centers integrate precise hormone monitoring, ultrasound tracking, algorithmic dosing, and safety safeguards to tailor gonadotropin induction protocols to each patient’s physiology, minimizing risk while maximizing effectiveness.
Purpose & Benefits
- Stimulate growth of multiple follicles (rather than just one), thereby increasing the number of ova available for conception or IVF cycles
- Overcome ovarian resistance to milder ovulation induction agents
- Improve the likelihood of ovulation in patients with anovulation or ovulatory dysfunction
- Provide greater control over follicular development timing and synchronization
- Enable more predictable cycles for IUI or timed ovulation procedures
- When integrated into IVF, contribute to a more robust ovarian response
- Allow fine-tuning of dosage based on real-time hormone and imaging feedback, thus reducing risk of incomplete response or under-stimulation
Ideal Candidates
Gonadotropin induction is typically indicated for:
- Women who failed to ovulate with first-line ovulation induction agents (clomiphene, letrozole)
- Patients with anovulation (e.g. PCOS, unexplained ovulatory dysfunction)
- Women undergoing IUI who need multiple mature follicles to boost success
- Patients preparing for IVF, where gonadotropins are a standard component of stimulation
- Poor responders or borderline cases where more aggressive stimulation is needed
- Women with normal ovarian reserve but poor response to oral agents
- Patients who prefer higher control and predictability in their cycles
Contraindications include severe ovarian disease, hormone-sensitive cancers, uncontrolled endocrine disorders, or contraindications to injectable hormone therapy.
Possible Risks & Complications
While gonadotropin induction is widely used and generally safe under careful monitoring, these risks exist:
- Ovarian Hyperstimulation Syndrome (OHSS): especially when multiple follicles grow aggressively
- Multiple pregnancy: due to multiple ovulations
- Hormonal side effects: bloating, mood changes, breast tenderness, nausea
- Cycle cancellation: if the response is poor (few follicles) or excessive (too many follicles)
- Injection site reactions: swelling, bruising, discomfort
- Emotional/psychological stress due to daily injections, visits, and hormonal fluctuations
- Rare complications: ovarian torsion, cysts, or overstimulation in extreme cases
To mitigate risk, Korean fertility centers employ low-dose start protocols, frequent ultrasound and hormone monitoring, mid-cycle dose adjustments, and trigger strategies that reduce OHSS risk.
Diagnostic & Monitoring Techniques Used
Gonadotropin induction is heavily dependent on diagnostics and monitoring to guide dosing and timing. Commonly used tools in Korean fertility centers include:
- Baseline hormonal tests (cycle day 2–3): FSH, LH, estradiol (E2), AMH, thyroid / endocrine panel
- Antral Follicle Count (AFC) via transvaginal ultrasound to assess ovarian reserve
- Serial ultrasound scans to track follicle count, size, and endometrial thickness
- Estradiol monitoring during stimulation to assess response to gonadotropins
- LH and progesterone checks to guard against premature luteinization
- Trigger threshold assessments: combining follicle size + hormone levels to decide when to administer trigger
- AI / algorithmic decision support: some clinics in Korea may use modeling systems to predict optimal dosing, response pattern, or OHSS risk
- Doppler or blood flow imaging (in some centers) to assess ovarian perfusion and uterine receptivity
This high-frequency monitoring allows adjustments mid-cycle to fine-tune stimulation and reduce risks.
Recovery & Aftercare
Because gonadotropin induction is a pharmacologic (non-surgical) approach, recovery is minimal:
- Patients may resume normal daily activities; strenuous exercise is often limited during stimulation
- Mild abdominal bloating or discomfort is common
- Hydration and rest are encouraged, especially to reduce OHSS risk
- Follow-up lab and ultrasound visits continue until ovulation/trigger and post-ovulation
- After ovulation or retrieval, luteal support (usually progesterone) is provided
- Emotional support and counseling may accompany treatment, given the demands of therapy
No major downtime is required; the main burden is monitoring.
Results & Longevity
- Response to gonadotropin induction is generally measurable and predictable in well-chosen patients
- In favorable cases, multiple mature follicles develop, increasing chances of ovulation or successful IUI/IVF outcomes
- The patterns from one cycle can inform dosing strategies in future cycles (dose adjustments, responsiveness)
- Longevity is cycle-specific: each new cycle may require adjustment based on current ovarian reserve and physiology
- When integrated into IVF, gonadotropin-based stimulation is core to achieving good egg yield and embryo availability
Treatment Process in Korea
Below is a typical workflow of gonadotropin ovulation induction in Korean fertility centers, and features that make Korea a preferred country for such therapy.
Step 1: Pre-induction Evaluation
- Comprehensive fertility assessment: hormonal panels, ultrasound (AFC), uterine and tubal imaging, partner sperm analysis
- Determination of ovarian reserve and baseline hormone environment
- Protocol design: selecting FSH / LH / hMG variants, starting dose, and monitoring schedule
Step 2: Induction Phase
- Daily or alternate-day injections of gonadotropins (FSH, LH, or mixed formulations)
- Frequent monitoring: ultrasound scans and blood hormone assays (e.g. estradiol) to assess follicular growth
- Mid-cycle adjustments: increase, decrease, or hold dose depending on response
Step 3: Triggering & Ovulation or Retrieval
- When follicle(s) reach target size and hormone levels align, an ovulation “trigger” (hCG or GnRH agonist) is given
- If the patient is in an IVF cycle, oocyte retrieval occurs ~34–36 hours post-trigger
- If in IUI or timed ovulation, insemination or related procedure follows at the appropriate window
Step 4: Luteal Support & Follow-up
- Progesterone (and sometimes estrogen) supplementation is given to support the luteal phase
- Post-ovulation monitoring of progesterone / hormone levels may continue
- In IVF, embryo transfer or freezing follows, depending on the cycle plan
Unique Korean Methods & Highlights
- Low-dose start protocols with fine increment adjustments reduce risk of overstimulation and OHSS
- AI-assisted hormone tracking and response modeling used in some centers to simulate optimal dose paths
- Rapid-turnaround hormone labs allow real-time adjustments
- Integrated data systems combining lab, imaging, patient history, and predictive models
- Multilingual care and international patient support embedded in many major Korean fertility hospitals
- High-volume centers with experience across diverse patient populations, which refines protocol sophistication

Cost Range (Details)
The cost of gonadotropin induction in Korea depends on medication dose, duration, monitoring frequency, and whether combined with IUI or IVF.
Based on published sources (e.g. Korean clinic cost listings) and fertility resources:
- Basic gonadotropin induction (medication + monitoring) might range USD 800 to USD 1,200 (depending on dosing and lab frequency)
- If combined with ovulation trigger and luteal support, the cost may go up to USD 1,200 to USD 1,800
- Gonadotropin induction plus IUI cycle packages may cost USD 1,500 to USD 2,200
- Gonadotropin used in IVF stimulation cycles (full stimulation package) may push the total stimulation / ovulation induction component toward USD 3,000 to USD 4,500 depending on drug types and monitoring intensity
These are approximate ranges; clinics often offer bundle packages for international patients including medications, monitoring, and logistics.
