Lupron and Lupride in IVF: What They Do and Why?

Lupron and Lupride are brand names for the same drug — leuprolide acetate, a GnRH agonist. In IVF, they are used to suppress the pituitary gland and prevent a premature LH surge before egg retrieval. Without this suppression, your body could release eggs too early, before they can be retrieved. Lupride does not stimulate egg growth — it simply puts the pituitary on hold so that your stimulation injections (FSH) have full control. Side effects resemble temporary menopause symptoms and usually resolve once the injection is stopped.

When your fertility doctor prescribes Lupride injections before your IVF cycle begins, the most common reaction is confusion. You expected to start growing follicles Instead, you’re being told to suppress your hormones first.

This is one of the most counterintuitive steps in the IVF process. Understanding why you need Lupride, what it actually does to your body, and how it fits into your overall protocol turns an anxiety-inducing instruction into a step you can approach with confidence.

This article covers everything patients in Hyderabad and across India want to know about Lupron and Lupride in IVF from the science behind the injection to what it feels like in practice.

Knowing what happens at each stage of IVF provides the full picture that makes each medication’s role make sense.

What Are Lupron and Lupride?

Lupron (manufactured by AbbVie) and Lupride (manufactured by Sun Pharma) are two brand names for the same active drug: leuprolide acetate.

Leuprolide acetate is a GnRH agonist it mimics GnRH (gonadotropin-releasing hormone), the hormone your hypothalamus naturally produces to signal the pituitary gland to release FSH and LH.

In India, Lupride is the commonly prescribed brand. Lupron is the original US brand name. Patients researching IVF internationally will encounter both names  they refer to the same drug with the same mechanism.

Lupride comes in two main forms:

• Daily subcutaneous injection (typically 0.5mg or 1mg) — used during IVF stimulation cycles
• Lupride Depot (monthly or 3-monthly injection) a slow-release formulation used for endometriosis treatment and sometimes in IVF preparation protocols

What Does Lupride Actually Do? The Mechanism Explained Simply

To understand why Lupride is needed, you first need to understand one specific risk in IVF: premature ovulation.

During a natural cycle, your brain controls a finely timed hormonal sequence. The pituitary gland releases an LH surge around day 12–14, which triggers the dominant follicle to release its egg. This is ovulation.

In IVF, the goal is to grow multiple follicles simultaneously using FSH injections. But if your pituitary gland sends an LH surge while follicles are still developing, the eggs release before they can be retrieved. This ruins the cycle entirely.

Lupride prevents this by suppressing the pituitary.

Here is how it works:

1. Initial flare effect (days 1–3): When first administered, Lupride briefly increases FSH and LH — a short burst called the “flare effect.” This is why it’s sometimes started in the mid-luteal phase of the previous cycle — the flare is allowed to happen at a time when it causes no harm.
2. Downregulation (after day 7–10): Continuous stimulation of GnRH receptors by Lupride causes those receptors to become desensitised. The pituitary essentially switches off. FSH and LH levels drop. Oestrogen falls. The ovaries become temporarily quiet.
3. Controlled stimulation: Once downregulation is confirmed (by blood tests and ultrasound), your doctor starts the FSH injections. Because the pituitary is suppressed, only the FSH you inject drives follicle growth. There is no risk of a spontaneous LH surge — no premature ovulation.
4. Trigger injection: When follicles reach the target size, a trigger injection (hCG or a GnRH agonist trigger) is given to mature the eggs — and egg retrieval happens 34–36 hours later.

In short: Lupride gives your doctor complete control over the timing of your cycle.

Side Effects of Lupride: What to Expect

Because Lupride suppresses oestrogen production, its side effects resemble a temporary, medically induced menopause. These are predictable, manageable, and resolve once the injections stop.

Common side effects:

• Hot flushes and night sweats
• Headaches
• Mood changes, irritability, low mood, tearfulness
• Fatigue
• Vaginal dryness
• Mild joint aches
• Disrupted sleep

Injection site effects:

• Redness, bruising, or mild swelling at the injection site
• Rotating injection sites (abdomen or thigh) reduces irritation

What is not typical:

• Severe pain at the injection site, if this occurs, contact your clinic
• Heavy bleeding, Lupride should suppress, not trigger, a bleed
• Significant weight gain, transient fluid retention is possible but substantial gain is not expected from Lupride alone

Important: Side effects vary widely between women. Some experience almost nothing. Others find the menopausal symptoms quite disruptive. If side effects are severe, contact your fertility team, dose adjustments may be possible, or your protocol may be reassessed.

When Is Lupride Used in Special Situations?

Endometriosis

For women with moderate-to-severe endometriosis, Lupride Depot (the slow-release monthly injection) is often given for 2–3 months before the IVF cycle begins. This suppresses endometriosis activity, reduces inflammatory markers in the endometrial environment, and improves implantation rates.

This is one of the more impactful uses of leuprolide in fertility — the pre-treatment period allows the uterine environment to recover from the effects of endometriosis before the embryo transfer attempt. If you have been told you need Lupride Depot before IVF due to endometriosis, this is why.

PCOS (Polycystic Ovary Syndrome)

Women with PCOS often have elevated basal LH levels, which can interfere with stimulation and egg quality. Lupride downregulation helps by suppressing this elevated LH baseline before stimulation begins. However, PCOS patients are also at higher risk of OHSS — so the long protocol with Lupride is used carefully, and a freeze-all strategy (no fresh transfer, all embryos frozen) is often planned in advance to reduce OHSS risk.

Poor Ovarian Reserve and Low AMH

For women with diminished ovarian reserve or low AMH, the long Lupride protocol is typically not the preferred choice. Deep pituitary suppression in a woman with low ovarian reserve can result in an over-suppressed ovary that responds poorly to stimulation. An antagonist protocol with shorter suppression and gentler overall approach is more commonly used in this population.

Lupride Depot: The Long-Acting Version

Lupride Depot is a different formulation from the daily injection. It contains microspheres that release leuprolide slowly over 28 days (1-month depot) or 3 months (3-month depot).

Uses in fertility:

• Pre-IVF endometriosis suppression: 2–3 monthly injections of Lupride Depot to treat active endometriosis before an IVF cycle. Evidence shows this can improve IVF outcomes in women with stages 3–4 endometriosis.
• Uterine fibroid reduction: Lupride Depot can temporarily shrink fibroids before IVF or surgical treatment.
• Thin endometrium cases: Occasionally used to allow the endometrium to recover before a frozen embryo transfer.

Lupride Depot causes the same hormonal suppression as daily Lupride so the same menopausal side effects apply, but sustained over the month between injections. Many women find the side effects easier to manage with the depot because they are predictable rather than daily fluctuations.

If your doctor has recommended Lupride injections either daily or depot — and you are unsure why or what protocol you are on, ask before you begin.

Understanding your own protocol makes you a more active participant in your IVF cycle, and studies consistently show that patients who understand their treatment have better emotional outcomes and compliance.

Our team at Mamata Fertility, Hyderabad, takes time to walk each patient through their protocol before the first injection. If you want a second opinion on the protocol recommended to you, or have questions about whether the long agonist or antagonist protocol is right for your situation, book a protocol review consultation.

Does the Protocol Affect IVF Success?

The protocol itself long agonist vs antagonist does not appear to significantly affect live birth rates in most patient groups when matched appropriately to the patient’s profile. What matters more is:

• Whether the protocol is right for your specific situation (reserve, diagnosis, previous response)
• Egg quality — which depends on age, reserve, and stimulation response, not the suppression protocol
• Embryo quality — the lab environment matters enormously
• Uterine receptivity — particularly relevant if frozen embryo transfer is planned

For a full picture of what actually determines whether IVF works, the protocol is just one piece. IVF success rates vary significantly by age regardless of which suppression medication is used.

Frequently Asked Questions

Q: What is the difference between Lupron and Lupride? They are the same drug leuprolide acetate sold under different brand names. Lupron is the original US brand (AbbVie). Lupride is the Indian brand (Sun Pharma). They have identical mechanisms and clinical profiles. If you are researching IVF internationally and see “Lupron protocol,” it refers to the same long GnRH agonist protocol used in India with Lupride.

Q: Does Lupride injection hurt?

The injection itself is a small subcutaneous (under the skin) injection  similar to insulin injections. Most patients describe it as a mild pinch. Some experience redness or bruising at the site, which is reduced by rotating injection sites and using room-temperature medication. The needle is very fine and the volume is small.

Q: Why do I feel like I’m going through menopause on Lupride?

Because, hormonally, you temporarily are. Lupride suppresses oestrogen production as part of its mechanism. Hot flushes, headaches, mood changes, and disrupted sleep are all the result of this low oestrogen state. These effects are completely temporary and resolve once stimulation begins (oestrogen rises again) or once the injection cycle ends.

Q: Will Lupride affect my egg quality?

Lupride itself does not impair egg quality. Its role is simply to prevent premature ovulation it has no direct effect on egg development. Egg quality is primarily determined by age, ovarian reserve, and the quality of FSH stimulation that follows.

Q: Can I get pregnant while on Lupride?

No. Lupride suppresses ovulation and creates a hormonal state unfavourable to pregnancy. It should not be taken if there is any possibility of existing pregnancy. Confirm with your doctor before starting if there is any chance of pregnancy.

Q: What happens if I miss a Lupride injection?

Contact your clinic immediately. Missing a dose risks pituitary “escape” the suppression wears off, and an LH surge could occur. Your clinic will advise whether to take the missed dose, adjust timing, or assess via blood test whether suppression has been maintained.

Q: Is Lupride safe?

Lupride (leuprolide acetate) has been used in fertility treatment for over three decades and has an extensive safety record. Short-term use in IVF cycles is considered safe. The menopausal side effects are the main concern they are real but temporary. Long-term use (for conditions like endometriosis) has a different safety profile, which your doctor will discuss separately.

Q: Can I self-administer Lupride at home? Yes, subcutaneous Lupride injections are routinely self-administered at home by IVF patients. Your clinic’s nursing team will demonstrate the technique before you begin. Most patients find it straightforward after the first few injections. Instructions on timing, storage (refrigeration required), and needle disposal should be provided by your clinic.

Final Thoughts: 

Lupride known internationally as Lupron is not a stimulation injection. It is the medication that makes stimulation safe by preventing premature ovulation. It gives your fertility team control over the precise timing of your cycle, ensures eggs are retrieved at exactly the right moment, and in special situations like endometriosis, actively improves the environment for the embryo.

The side effects are real but temporary and predictable once you know why they happen. Understanding that you are experiencing a medically induced low-oestrogen state makes the hot flushes and mood changes far less alarming.
