Why are Gonal-f and Menopur often used together?
Gonal-f and Menopur are routinely combined in fertility treatments such as IVF, harnessing the benefits of both FSH and LH hormone support for optimal follicle development and maturation. This dual-therapy approach allows fertility specialists to tailor stimulation protocols to each patient’s unique hormonal needs, potentially improving treatment outcomes.
What Is Gonal-f?
Gonal-f is a recombinant medication composed solely of follicle-stimulating hormone (FSH). FSH is essential for the growth and maturation of ovarian follicles, each of which contains an egg. In fertility treatments, Gonal-f boosts the ovaries’ ability to produce multiple mature eggs during a cycle, increasing the likelihood of successful fertilization.
What Is Menopur?
Menopur is a human menopausal gonadotropin (hMG) containing both FSH and luteinizing hormone (LH). The LH component plays a crucial role in final follicle maturation, triggering ovulation, and supporting hormone balance throughout the cycle. Menopur is especially valued for patients with low LH levels, diminished ovarian reserve, or poor response to prior stimulation.
Why Combine Gonal-f and Menopur?
Combining Gonal-f and Menopur allows for more precise control over FSH and LH levels, enabling physicians to adjust the hormone ratio according to individual patient profiles. This tailored approach can benefit specific patient groups. The addition of LH (via Menopur) can enhance follicle maturation and hormonal balance, possibly increasing live birth rates in select populations. The combination can result in improved fertility outcomes, especially for those who failed previous cycles using FSH-only stimulation.

Are Gonal-f and Menopur Ever Used Separately?
Yes, both medications can be prescribed independently:
- Gonal-f alone: Suitable for women with adequate natural LH production, or in cases where additional LH is unnecessary.
- Menopur alone: Sometimes preferred for economic reasons or provider experience; best suited for specific patient profiles or after evaluating hormone levels through blood tests.
The decision to use one or both depends on a careful assessment of age, ovarian reserve, past treatment responses, and individualized hormone testing.
Final Takeaway
The combination of Gonal-f and Menopur is common and safe when managed by a fertility expert, offering a customized approach that aims to maximize ovarian response in IVF and other fertility treatments. As with all fertility interventions, protocols should be personalized to the patient’s unique clinical factors for the best results.

When is the best time to take metformin?
Metformin should be taken after having a meal or eating food, especially when you are first starting treatment. This can help reduce any stomach side effects like nausea, vomiting, diarrhea or gas. These side effects generally go away within a few weeks after starting treatment. Continue reading
Can you take metformin without food?
If you take metformin without food you may end up with an upset stomach, especially if you are just starting treatment. Nausea and vomiting are some of the most common side effects with metformin and can occur in over 30% of patients.

Does metformin lower A1C, if so how much?
When metformin is used alone as monotherapy, it lowers A1C by about 1% to 2% on average. A1C is a measure of longer-term blood sugar control. In most patients, metformin is suggested as the initial treatment for type 2 diabetes, but its glucose-lowering effect may not be adequate for all patients if used alone. Continue reading
