In short
Follitropin Delta, also known as REKOVELLE, is a recombinant human follicle-stimulating hormone (FSH) used in controlled ovarian stimulation for assisted reproductive technologies like in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). This article explores the use of Follitropin Delta in clinical trials, highlighting its effectiveness, safety, and unique individualized dosing approach based on a woman's anti-Müllerian hormone (AMH) levels and body weight.

What is Follitropin Delta?
Follitropin Delta is a medication used in fertility treatments. It is a type of hormone called recombinant human follicle-stimulating hormone (rFSH). This means it is a laboratory-made version of the natural hormone FSH that stimulates egg production in women. Follitropin Delta is also known by the brand names REKOVELLE and FE 999049.
How Does Follitropin Delta Work?
Follitropin Delta works by stimulating the ovaries to produce eggs. It is used as part of controlled ovarian stimulation in women undergoing fertility treatments such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). These are procedures where eggs are collected from a woman's ovaries and fertilized with sperm in a laboratory to create embryos, which are then transferred back into the woman's uterus.
What Conditions Does Follitropin Delta Treat?
Follitropin Delta is used to treat infertility in women. Specifically, it is prescribed for:
- Controlled ovarian stimulation: This is a process used in fertility treatments to stimulate the ovaries to produce multiple eggs.
- Preparation for IVF or ICSI: These are assisted reproductive technologies used to help couples with fertility issues conceive.
- Intrauterine insemination: This is a fertility treatment where sperm is placed directly into the uterus during ovulation.
How is Follitropin Delta Administered?
Follitropin Delta is administered as a subcutaneous injection, which means it is injected just under the skin. It typically comes in a pre-filled injection pen for ease of use. The medication is usually injected once daily during the stimulation phase of the fertility treatment cycle.
Dosing of Follitropin Delta
One of the unique features of Follitropin Delta is its individualized dosing regimen. The dose is determined based on two main factors:
- Body weight: This helps estimate how the medication will be distributed in the body.
- Anti-Müllerian hormone (AMH) level: This is a hormone that helps predict how a woman's ovaries will respond to stimulation.
This personalized approach aims to reduce the risk of under- or over-response to the treatment. The daily dose is usually fixed throughout the stimulation period, which can last up to 20 days.
Effectiveness of Follitropin Delta
Clinical trials have shown that Follitropin Delta is effective in stimulating egg production for fertility treatments. Some key findings include:
- It is as effective as other FSH medications in terms of pregnancy rates and live birth rates.
- The individualized dosing approach helps more women achieve the optimal number of eggs (typically considered to be 8-14 eggs).
- It may reduce the need for dose adjustments during treatment compared to conventional FSH medications.
Potential Side Effects and Risks
Like all medications, Follitropin Delta can cause side effects. Some potential side effects include:
- Injection site reactions: Such as redness, pain, itching, swelling, or bruising at the injection site.
- Ovarian Hyperstimulation Syndrome (OHSS): This is a condition where the ovaries become swollen and painful. Symptoms can include abdominal pain, bloating, nausea, and in severe cases, shortness of breath. The individualized dosing of Follitropin Delta aims to reduce the risk of OHSS.
- Multiple pregnancies: As with all fertility treatments, there is a risk of multiple pregnancies (twins, triplets, etc.).
It's important to discuss all potential risks and side effects with your healthcare provider before starting treatment.
Ongoing Research on Follitropin Delta
Several clinical trials are ongoing or have been recently completed to further study Follitropin Delta. These studies are looking at various aspects of the medication, including:
- Its use in different populations, such as women in different age groups or with different AMH levels.
- Its effectiveness when used in combination with other fertility medications.
- Its use in specific fertility treatment protocols, such as freeze-all cycles where all embryos are frozen for later use.
- Its effectiveness and safety in real-world clinical practice settings.
These ongoing studies will help to further refine the use of Follitropin Delta and potentially expand its applications in fertility treatment.
