If you are planning IVF, you may be told that you “need a better injection” — and your doctor may recommend Pergoveris instead of standard recombinant FSH injections like Gonal-F.
The pitch sounds scientific:
“Pergoveris contains both FSH and LH.
So it must work better than FSH alone.”
More hormones… must mean better results, right?
Not always.
Let’s separate science from sales tactics — so you can choose wisely.
FAQs: Pergoveris vs Gonal-F Explained Simply
What is Gonal-F?
Gonal-F is a recombinant FSH (Follicle Stimulating Hormone) injection used to stimulate your ovaries to produce multiple eggs during IVF.
It contains:
✅ Only FSH
✅ Synthetic, purified hormone
✅ Exact dosing
✅ Predictable behaviour
✅ Consistent response
It is the worldwide standard for ovarian stimulation.
What is Pergoveris?
Pergoveris contains:
- FSH
- LH (Luteinizing Hormone)
So essentially, Pergoveris = Gonal-F + LH.
Because it contains two hormones, it costs significantly more.
But here’s the important question:
Does more hormone = better success?
Not necessarily.
Isn’t LH also important for egg development?
Yes — but only if it is lacking.
Most IVF patients already produce enough LH naturally.
Your pituitary gland does not shut down completely during IVF.
So in most women: 👉 Endogenous (your own) LH is entirely adequate.
Adding more LH is like pouring water into an already full glass.
It does not increase the level.
It just increases the bill.
So when is LH supplementation actually needed?
LH may be helpful in selected cases:
✅ Very poor ovarian responders
✅ Advanced reproductive age
✅ Hypothalamic or pituitary disorders
✅ Rare hormonal deficiencies
✅ Refractory cycles with documented LH deficiency
But this applies to a small minority of patients.
Not everyone.
Not routinely.
Not automatically.
Then why are pharma companies pushing Pergoveris so aggressively?
Because:
🔹 It’s a premium product
🔹 It’s more expensive
🔹 It increases billing
🔹 It has a better marketing story
🔹 It sounds “advanced”
🔹 It gives the illusion of personalization
Unfortunately…
Good marketing rarely equals better medicine.
Drug companies market combinations for profits.
Doctors must prescribe for patients.
The two interests don’t always align.
Is there scientific proof that Pergoveris works better than Gonal-F?
Not in the general IVF population.
Large studies show:
- No higher pregnancy rate
- No improved egg quality
- No superior embryo development
- No consistent advantage
- No better live birth outcomes
If success were higher, everyone would use it exclusively.
The fact that FSH-only remains the gold standard tells you everything.
Then why do clinics say Pergoveris is “stronger”?
Because “more hormones” creates psychological confidence.
But biology doesn’t work on emotions.
It works on receptors.
And in IVF patients:
FSH already works well.
LH is usually NOT missing.
Can excess LH cause harm?
Yes — sometimes.
Too much LH may:
- Compromise egg quality
- Increase follicular atresia
- Disrupt hormone balance
- Reduce embryo competence
- Add cost without benefit
- Unnecessary hormones complicate otherwise clean protocols.
In IVF…
Simple often works best.
Why does my clinic push expensive injections?
Follow the money.
Some clinics:
- Choose margin over medicine
- Follow pharma influence blindly
- Use “latest” instead of “evidence”
- Upsell under the illusion of “best”
- Avoid explaining
- Transparency is rare.
- So are honest doctors.
Should I refuse Pergoveris?
Not blindly.
But you should ask why.
Ask:
✅ Do I have proven LH deficiency?
✅ What data supports this choice for ME?
✅ What is the added benefit?
✅ Will outcomes improve — or just costs?
✅ Can you show me evidence?
A good doctor welcomes questions.
A bad one fears them.
If Gonal-F is enough, why complicate treatment?
Because:
- Simpler protocols are safer
- Predictability improves outcomes
- Costs reduce stress
- Treatment stays focused
- Ovaries respond more naturally
- IVF is hard enough.
It shouldn’t be turned into a chemistry experiment.
Final Thought
If LH were mandatory…
Gonal-F would be obsolete.
It isn’t.
And there is a reason.
You don’t need more medication.
You need the right medication.
Bigger prescriptions do not mean better medicine.
They often mean better billing.
