The first time I had to inject Menopur, I stared at that vial of powder for a solid ten minutes. There I was, April 2023, about to start my first — and thankfully only — round of IVF stims with both Menopur and Gonal-F in my arsenal.
If you're reading this, you're probably sitting with your own box of fertility meds, wondering what the hell you've gotten yourself into. The Menopur vs Gonal-F debate is real, and I'm here to give you the unfiltered truth about both from someone who's been stabbed by both.
Let's be real — nobody prepares you for how different these two medications actually feel, cost, and work in your body. Your clinic probably handed you a medication calendar and said "good luck," but I'm going to tell you what they didn't.
What Actually Are These Things?
Gonal-F and Menopur are both gonadotropins — hormones that tell your ovaries to wake up and start cranking out eggs. But that's where the similarities end.
Gonal-F is recombinant FSH (follicle stimulating hormone) made in a lab. It's clean, precise, and comes in a fancy pen that makes you feel like you're in a pharmaceutical commercial.
Menopur is extracted from the urine of postmenopausal women. I know, I know — it sounds gross, but it contains both FSH and LH (luteinizing hormone) plus other trace hormones that some REs swear by. It's like the difference between synthetic vanilla and vanilla beans — one's cleaner, one's more complex.
Most protocols use both because they work differently. Gonal-F gives you that steady FSH stimulation, while Menopur adds the LH component that can help with egg maturation. My RE explained it like having a lead singer and backup vocals — they're better together.
The Pain Factor (Spoiler: Menopur Wins This Battle)
Listen, anyone who tells you Menopur doesn't hurt is either lying or has nerve damage. That shit burns like you're injecting liquid fire into your stomach.
The Gonal-F pen? Barely felt it. Sometimes I'd check to make sure it actually went in. The needle is tiny, the medication goes in smooth, and you're done in seconds.
Menopur though — Jesus Christ. The burn starts immediately and radiates out from the injection site for a solid five minutes. I'd literally have to psyche myself up for it every night. "Okay Michaela, just remember why you're doing this. Think about Sadie. You can handle thirty seconds of fire stomach."
The burning isn't just in your head either. Menopur has a pH that's different from your body's natural pH, which is why it stings. Some people say icing the area first helps, but honestly? Nothing really helps. You just get used to it.
Mixing Menopur: A Chemistry Lesson Nobody Asked For
Here's where Menopur becomes a whole production. Gonal-F comes pre-mixed in a pen — twist, inject, done. Menopur requires you to become a pharmacist.
You get vials of powder and saline, and you have to mix them yourself. My protocol was 150 units, which meant mixing two vials of powder with one vial of saline. The process:
1. Draw up the saline into the syringe
2. Inject it into the first powder vial
3. Swirl (don't shake!) until dissolved
4. Draw it back up
5. Inject into the second powder vial
6. Swirl again
7. Draw up the final mixture
8. Inject into your poor, unsuspecting stomach
The whole process takes about ten minutes if you're being careful — which you should be, because this stuff costs more than my rent.
Pro tip: Let the mixed solution sit for a few minutes before injecting. Sometimes that helps with the burning. Sometimes.
The Cost Nightmare
Let's talk money, because these medications will bankrupt you faster than a gambling addiction.
At my US pharmacy, a 900-unit box of Gonal-F was running about $1,200. The Menopur was even worse — $400 per 75-unit vial, and I needed multiple vials per shot. For my entire stims cycle, I was looking at about $3,500 just for these two medications.
$3,500 to inject myself with hormones that made me feel like I was losing my mind.
This is where I have to mention that international pharmacy referrals exist for a reason. The same medications that cost me $3,500 in the US? Available internationally for around $700. Same manufacturers, same quality, legal to import for personal use. I wish I'd known about this option before I emptied my savings account.
If you're paying out of pocket like I was (thanks, Aetna, for that discriminatory coverage denial), definitely explore international options. Your bank account will thank you.
Side Effects: The Real Talk
Both medications essentially turn you into a hormonal time bomb, but they do it slightly differently.
Gonal-F side effects for me:
- Mild headaches
- Some bloating
- Mood swings (nothing too dramatic)
- Fatigue
Menopur side effects:
- Everything Gonal-F caused, but amplified
- Serious bloating (I looked six months pregnant by day 8)
- Nausea
- The injection site reactions from hell
- Emotional volatility that would make a soap opera character seem stable
The combination of both? I was basically a walking science experiment. By day 10 of stims, I could barely fit into my pants and was crying at Subaru commercials.
Which One Actually Works Better?
Here's the thing — you can't really separate their effectiveness because most protocols use them together. My AFC was 11, I had 20 follicles respond to stims, and ended up with 7 embryos. Was that the Gonal-F? The Menopur? The combination?
Your RE prescribes them together for a reason. The Gonal-F provides consistent FSH stimulation, while the Menopur adds that LH component plus other trace hormones that can help with egg quality. They're like a fertility medication power couple.
Some REs prefer all-Gonal-F protocols for people who respond really well to FSH alone. Others swear by adding Menopur for anyone over 35 or with diminished ovarian reserve. It really depends on your specific situation.
My Honest Take
If I had to do it again, I'd probably ask about doing the same protocol. Yeah, the Menopur sucked, but it worked.
Would I have preferred an all-Gonal-F protocol to avoid the nightly torture sessions? Absolutely. But I also know that my autoimmune issues and diminished ovarian reserve meant I needed all the help I could get.
The Menopur vs Gonal-F debate isn't really about which one is "better" — it's about which combination gives you the best chance of success. And sometimes that means accepting that you're going to spend two weeks injecting liquid fire into your stomach.
The Bottom Line
Both medications suck in their own special ways. Gonal-F is easier and less painful but more expensive per unit. Menopur hurts like hell and requires a chemistry degree to mix, but provides hormones you can't get from recombinant sources.
Most of us don't get to choose — our REs prescribe what they think will work best for our specific situation. But knowing what you're getting into helps. The Gonal-F won't hurt. The Menopur will burn like fire, and that's normal.
You'll get through it. I promise. And hopefully, like me, you'll only have to do it once.
