Understanding Ovarian Stimulation: Recommended IUI Medications in Delhi

Navigating the world of fertility medications can feel like learning a new language.
When preparing for Intrauterine Insemination (IUI), the goal of medication is to gently encourage your ovaries to produce one or two healthy, mature eggs, increasing the “target size” for the sperm.
The most commonly recommended medications for ovarian stimulation in IUI include oral tablets like Clomiphene Citrate or Letrozole, and occasionally injectable Gonadotropins (FSH), followed by an HCG ‘trigger shot’ to pinpoint the exact time of ovulation.
As a reproductive health expert with over 10 years of experience, I, Dr. Mannan Gupta, have spent a decade at Dr. Mannan IVF Centre helping families understand that the “best” medication isn’t universal—it is the one tailored specifically to your body’s hormonal profile.
Key Takeaways
- Primary Goal: To stimulate the growth of 1–3 mature follicles (the fluid-filled sacs containing eggs).
- Oral Medications: Letrozole and Clomiphene are usually the first-line treatments for IUI.
- Injectables: Gonadotropins may be used for patients who don’t respond to oral tablets.
- The Trigger: An HCG injection ensures the IUI procedure happens exactly when the egg is released.
Why do we need medications for an IUI cycle?
While IUI can be performed during a natural cycle, we often recommend “stimulated” cycles to improve the odds. In a natural cycle, the body typically releases only one egg.
By using mild stimulation, we aim for a “superovulation” effect where two or three eggs are available.
As an IUI specialist, I evaluate your ovarian reserve—the “bank” of eggs you have—using blood tests like AMH and baseline ultrasounds.
This helps us choose a dosage that is effective but safe. To see how these medications fit into the broader timeline, you can review our Step-by-Step IUI Process in Delhi: From First Scan to Pregnancy Test.
What are the differences between oral IUI medications?
Oral medications are usually the starting point for most patients because they are effective, affordable, and easy to administer. Two drugs dominate this category: Clomiphene Citrate and Letrozole.
Both work by tricking the brain into thinking estrogen levels are low, which in turn prompts the body to produce more Follicle Stimulating Hormone (FSH).
Medication | How it Works | Common Uses |
Clomiphene (Clomid) | Blocks estrogen receptors to boost FSH production. | Unexplained infertility and general ovulation issues. |
Letrozole (Femara) | Temporarily lowers estrogen production. | Often preferred for PCOS; usually has fewer side effects on uterine lining. |
Many patients at our IUI treatment hospital in New Delhi find that Letrozole offers a better balance, as it tends to maintain a healthier uterine lining (the “soil” where the embryo plants) compared to Clomiphene.

When are injectable gonadotropins recommended?
If oral medications do not result in healthy follicle growth, or if we are dealing with specific hormonal deficiencies, we move to injectable Gonadotropins.
These injections contain pure FSH (Follicle Stimulating Hormone) or a mix of FSH and LH (Luteinizing Hormone).
These are bio-identical hormones that directly tell the ovaries to grow follicles. Because they are more potent than oral tablets, they require closer monitoring via frequent ultrasounds to ensure the ovaries don’t over-respond, which is a key part of maintaining clinical safety.
What is the purpose of the "Trigger Shot"?
The final piece of the IUI Medications in Delhi puzzle is the HCG (Human Chorionic Gonadotropin) injection.
This is often called the “trigger” because it mimics the natural LH surge that tells the ovary to release the mature egg.
Once this shot is administered, ovulation typically occurs within 36 to 40 hours.
This allow us to schedule the IUI procedure with surgical precision, ensuring the prepared sperm are waiting in the uterus exactly when the egg arrives in the fallopian tube.
After the procedure, the “two-week wait” begins. If you are curious about what to look out for during this time, you can read our guide on What are the First Signs of IUI Success?

How do we monitor your response to these medications?
Monitoring is the most critical phase of the stimulation process. We use Transvaginal Ultrasound (TVS) to measure the diameter of the growing follicles. A follicle is considered “mature” when it reaches 18mm to 20mm in size.
Being the Best Fertility Clinic New Delhi, we also keep a close eye on the thickness of your uterine lining.
If the medication is working well but the lining remains thin, we may adjust the protocol or add estrogen supplements to ensure the uterus is prepared for implantation.
What side effects should I expect from stimulation?
Most women tolerate IUI medications very well, but because we are shifting your hormones, some mild symptoms are normal.
You might experience minor bloating, breast tenderness, or slight mood swings—similar to how you might feel right before a period.
If you are using injectables, there is a very small risk of Ovarian Hyperstimulation Syndrome (OHSS), where the ovaries become swollen.
We prevent this through “low and slow” dosing and frequent monitoring, ensuring your safety is never compromised for the sake of the procedure.
How do these medications affect long-term maternal health?
A common concern among my patients is whether these hormones have long-term effects.
Current medical research indicates that the short-term use of these medications for a few IUI cycles does not increase the risk of future health complications or “deplete” your egg supply.
Our focus remains on preventive awareness. We treat each cycle not just as a chance for pregnancy, but as a step toward a healthy, full-term delivery.
Whether that eventually leads to a natural birth or a planned C-section delivery, the health of the mother remains our top clinical priority.
Conclusion
Choosing the right medication for ovarian stimulation is a delicate balance of science and clinical intuition.
Whether we start with simple oral tablets like Letrozole or require the direct support of injectables, the goal is always to create the safest and most effective environment for conception.
At Dr. Mannan IVF Centre, Delhi, we believe that an informed patient is a relaxed patient.
By understanding how these medications work, you can move forward with confidence, knowing that every pill or injection is a carefully planned step toward holding your baby in your arms.
Frequently Asked Questions
1. Can I take these IUI medications if I have regular periods?
Yes. Even if you ovulate naturally, “unexplained infertility” is often treated with mild stimulation to increase the number of eggs available, which statistically improves the chances of success per cycle.
2. Are the injections for IUI painful to administer?
Most modern gonadotropin injections come in “pen” form with very fine needles, similar to insulin pens. Most patients find them nearly painless and are comfortable administering them at home after a quick demonstration.
3. What happens if I produce too many follicles?
If an ultrasound shows more than 3 or 4 mature follicles, we may advise canceling the IUI or converting it to an IVF cycle. This is a safety measure to prevent high-order multiple pregnancies (like triplets), which carry higher risks for both mother and babies.
4. Do I need to change my diet while taking these medications?
While there is no “magic diet,” staying hydrated and eating a protein-rich, balanced diet helps your body manage the hormonal shifts more comfortably. Avoiding excessive caffeine and alcohol is also recommended.
5. How much do IUI medications typically cost in New Delhi?
Oral medications are quite affordable, while injectables are more expensive due to the complex way they are manufactured. We always provide a transparent breakdown of costs so you can plan your treatment without surprises.
