pergoveris r-FSH r-LH dosing ovarian stimulation
Now I have solid information to give a detailed, clinically relevant answer. Let me analyze this patient's profile carefully.
Pergoveris Dosing for This Patient
Patient Profile Analysis
| Parameter | Value | Interpretation |
|---|---|---|
| Age | 35 years | Relevant but not advanced age |
| BMI | Normal | No dose adjustment needed for weight |
| Day 2 FSH | 13 IU/L | Mildly elevated - suggests diminished ovarian reserve (DOR) |
| Day 2 LH | 12 IU/L | Normal to slightly elevated |
| FSH:LH ratio | ~1.1:1 | Near-normal ratio |
Key Clinical Point
This patient does not fit the classical Pergoveris indication. Pergoveris (r-hFSH 150 IU + r-hLH 75 IU) is licensed for women with severe LH and FSH deficiency (hypogonadotropic hypogonadism, endogenous LH < 1.2 IU/L). Your patient has:
- FSH of 13 (elevated, not deficient) - pointing to diminished ovarian reserve (DOR)
- LH of 12 (normal/slightly elevated) - not LH-deficient
This is important context for interpreting why and how Pergoveris might be used here.
Why Pergoveris Might Still Be Chosen
In clinical practice (off-label / individualized protocols), Pergoveris is used in poor/diminished ovarian reserve patients because:
- Added r-hLH activity supports steroidogenesis and follicular maturation in sub-optimal responders
- The "LH ceiling" concept - some DOR patients benefit from exogenous LH co-administration
- Poor responders with elevated basal FSH often respond better with combined FSH+LH stimulation
Recommended Dose
Standard starting dose: Pergoveris 150 IU FSH / 75 IU LH daily (1 vial/pen)
For a DOR/poor responder profile like this patient (elevated Day 2 FSH of 13), many fertility specialists use a higher starting dose:
- Pergoveris 300 IU FSH / 150 IU LH daily (2 doses or the double dose) - this is the dose used in the 2025 Frontiers in Endocrinology RCT specifically for poor ovarian responders, starting from Day 2 of the cycle
- The FSH:LH 2:1 ratio is maintained at any dose level
Dose Titration Protocol
- Start on Day 2-3 of menstruation: Pergoveris 150-300 IU FSH / 75-150 IU LH daily SC
- Monitor from Day 5-6: Transvaginal ultrasound + serum estradiol every 2-3 days
- Dose adjustment: If response is suboptimal after 7-14 days, increase FSH by 37.5-75 IU increments (using additional follitropin alfa, since adding more Pergoveris also increases LH)
- Duration: Up to 5 weeks per cycle if needed
- Trigger: When lead follicle reaches 17-18 mm, administer r-hCG 250 mcg or u-hCG 5,000-10,000 IU
Practical Recommendation for This Patient
Given:
- Day 2 FSH 13 (DOR range) - indicating she will likely be a poor/sub-optimal responder
- Normal BMI (no dose increase for weight)
- Age 35 (still reasonable ovarian reserve but borderline)
Start with Pergoveris 150 IU FSH / 75 IU LH daily, with a low threshold to escalate to 300 IU FSH / 150 IU LH if Day 6 scan shows poor follicular recruitment (< 3 antral follicles responding). Many clinicians with this FSH profile will start at the higher 300/150 IU dose directly to avoid cycle cancellation.
Important caveat: This patient's LH is not deficient (LH 12 is normal), so the strict licensed indication for Pergoveris does not apply. The choice of Pergoveris vs. pure FSH (e.g., Gonal-F, Puregon) or FSH+HMG should be based on your institutional protocol, AFC (antral follicle count), AMH level, and prior stimulation history. An AMH would significantly refine this dosing decision.

This additional history changes the picture significantly. Here is a full updated analysis:
Updated Assessment: Poor Ovarian Responder with 2 Failed Minimal Stimulation Cycles
POSEIDON Classification
This patient fits POSEIDON Group 3 (or possibly Group 4):
| POSEIDON Criteria | This Patient |
|---|---|
| Age < 35 | Yes (35, borderline) |
| Reduced ovarian reserve | Yes - Day 2 FSH 13 (elevated), only 1 blastocyst across 2 cycles |
| Poor response to prior stimulation | Yes - minimal stim x2, low M2, 1 x 2BB embryo only |
| Unexpected vs. expected POR | Expected (biomarkers abnormal) |
She has already had 2 cycles of minimal stimulation that failed to yield adequate oocytes. Continuing with the same approach violates the basic principle of IVF management.
Why Minimal Stimulation Was Insufficient
- FSH of 13 signals depleted follicular cohort - there are simply fewer follicles to recruit
- Minimal stim (low-dose clomiphene/letrozole ± low FSH) relies on natural follicle selection - fine for normal reserve, poor for DOR
- The 2:1 FSH:LH ratio in Pergoveris is relevant here because DOR patients often have relative LH excess (LH 12) - this needs careful interpretation
Recommended Protocol Change
Step up to maximal/high-dose FSH stimulation - this is now the standard next step after failed minimal stimulation in a poor responder.
Pergoveris Dose Recommendation
| Scenario | Dose |
|---|---|
| Standard Pergoveris starting dose | 150 IU FSH / 75 IU LH |
| For this patient (DOR + 2 failed minimal stim) | 300 IU FSH / 150 IU LH daily |
- Start on Day 2 of cycle, SC injection daily
- The 300/150 IU dose is exactly what was used in the 2025 poor responder RCT (Frontiers Endocrinology) and is appropriate for established poor responders
- If after Day 5-6 ultrasound the response is still suboptimal (< 3 follicles > 10mm), you can supplement with additional follitropin alfa 75 IU to push FSH to 375 IU while keeping LH stable
Additional Adjuncts to Consider
- GnRH Antagonist protocol (not long agonist) - prevents premature LH surge without suppressing the already limited follicular cohort; preferred in poor responders
- Testosterone priming (transdermal testosterone 5-10 mg/day for 5-7 days before stimulation) - upregulates FSH receptors; evidence supports improved oocyte yield in DOR
- Growth hormone co-treatment (1.33-2.5 mg/day SC during stimulation) - POSEIDON group evidence supports improved live birth rates in poor responders
- Consider AMH measurement if not already done - will help confirm prognosis and guide counselling
Key Clinical Caveat
- This patient's LH is 12 (not deficient) - so adding extra exogenous LH (as in Pergoveris) carries a theoretical risk of exceeding the LH "ceiling" and impairing folliculogenesis
- Some evidence suggests that in patients with elevated basal LH, pure FSH (Gonal-F 300-450 IU) may actually be preferable over an FSH+LH combination
- The decision between Pergoveris 300/150 IU vs. pure rFSH 300-450 IU should factor in prior cycle LH levels during stimulation - if Pergoveris is chosen, close monitoring of LH during stimulation is important
Bottom line: If proceeding with Pergoveris, use 300 IU FSH / 150 IU LH starting Day 2, with a GnRH antagonist protocol, and strongly consider adding testosterone priming and/or growth hormone. If prior cycles showed LH surges or excessive LH rise during stimulation, switch to pure FSH instead.

Foligraf 75 IU 150 IU composition follitropin alfa pure FSH India
Confirmed. Foligraf is pure r-hFSH (follitropin alfa) - no LH component. This makes your add-on strategy very logical. Here's the complete picture:
Your Proposed Protocol: Pergoveris 150 IU + Foligraf Add-on
Composition Clarity
| Drug | FSH | LH |
|---|---|---|
| Pergoveris 150 IU | 150 IU r-hFSH | 75 IU r-hLH |
| Foligraf 75 IU | 75 IU r-hFSH | 0 |
| Foligraf 150 IU | 150 IU r-hFSH | 0 |
Why This Add-on Strategy is Sound
Adding Foligraf (pure FSH) on top of Pergoveris is the textbook step-up approach:
- It increases total FSH dose to recruit more follicles
- LH dose stays fixed at 75 IU (from Pergoveris) - avoiding LH excess in a patient who already has a basal LH of 12
- This is exactly how Pergoveris is designed to be supplemented - the product monograph explicitly states: "if FSH dose increase is needed, use a licensed follitropin alfa preparation"
Recommended Step-Up Schedule
Start: Pergoveris 150/75 IU daily from Day 2
Day 5-6 scan - if poor response (< 2-3 follicles ≥ 10mm, low E2):
| Add-on choice | Total FSH | Total LH | Suitable when |
|---|---|---|---|
| + Foligraf 75 IU | 225 IU FSH / 75 IU LH | Modest step-up, first escalation | |
| + Foligraf 150 IU | 300 IU FSH / 75 IU LH | Stronger step-up, this patient's history warrants this |
For this patient specifically - given 2 prior failed minimal stim cycles - adding Foligraf 150 IU (giving 300 IU total FSH + 75 IU LH) is the more appropriate escalation dose if Day 5-6 response is poor.
Monitoring Checkpoints
| Day | Action |
|---|---|
| Day 2 | Start Pergoveris 150/75 IU |
| Day 5-6 | TVS + E2 - assess follicle count and size |
| If poor response | Add Foligraf 75 or 150 IU, continue monitoring every 2-3 days |
| Day 7-8 re-check | If still < 2 follicles > 12mm, consider cycle cancellation vs. convert to IUI |
| Lead follicle 17-18mm | Trigger with r-hCG 250 mcg or u-hCG 10,000 IU |
One Important Watch Point
This patient's basal LH is 12 IU/L (not low). During stimulation on Pergoveris, her LH may rise further. Check mid-stimulation LH (Day 6-7):
- If LH > 12-15 IU/L during stimulation - the exogenous LH from Pergoveris may be unnecessary or excessive
- In that scenario, continuing with just Foligraf (pure FSH) alone would be preferable in the next cycle
Summary: Yes, adding Foligraf 75 or 150 IU to Pergoveris 150 IU is a safe, well-reasoned, and pharmacologically sound step-up. Given this patient's history of two poor responses, having a low threshold to add Foligraf 150 IU (rather than waiting) is justified. Total FSH cap should not exceed 450 IU/day.
