Starting an IVF (in vitro fertilisation) journey is an emotional, physical, and mental commitment, and one of the most commonly asked questions is: “How many injections will I need?”

If you’ve landed here, chances are you’re looking for clarity on what to expect.

Whether you’re just exploring IVF or are already gearing up for the process, this blog will take you through the answers in a way that’s easy to understand—without the heavy medical lingo. 

• IVF requires a series of planned hormone injections that help the ovaries produce multiple eggs and prepare the body for fertilisation and embryo transfer.

• The number of injections varies for each woman, but most IVF cycles involve daily shots over 8–14 days, totaling around 20–60 injections depending on the protocol.

• Though injections may feel intimidating at first, with proper guidance and routine, they become manageable — and each one plays a key role in improving IVF success.

Before we dig into the details, let’s acknowledge how intimidating the idea of daily injections can be. If you’re nervous about needles, you’re not alone.

Many people feel the same way at the start. However, understanding the purpose of these injections and how they fit into the IVF process can help alleviate some of that fear. 

The injections during IVF aren’t random—they’re carefully planned steps that form the backbone of the ivf treatment.

Their job?

To regulate and stimulate your body in preparation for retrieving eggs, fertilising them, and ultimately, transferring embryos. 

IVF injections aren’t “one-size-fits-all.”

The exact number and types of injections depend on your specific protocol and individual factors like age, hormone levels, and ovarian reserve.

However, here’s a breakdown of the types you’re most likely to encounter:

1. Ovarian Stimulation Medications 

Purpose: To stimulate your ovaries to produce multiple eggs rather than the usual single egg per cycle. 

Common Medications:

• Gonadotropins (e.g., Gonal-F, Menopur, or Follistim): These help your ovaries mature multiple eggs simultaneously. 

  Frequency: Administered once or twice daily for about 8-14 days, depending on how your ovaries respond.

2. Preventing Premature Ovulation 

Purpose: To stop your body from releasing eggs too early. 

Common Medications:

• GnRH Antagonists (e.g., Cetrotide or Ganirelix): These ensure your eggs don’t ovulate before they’re retrieved. 
• GnRH Agonists (e.g., Lupron): Sometimes used for the same purpose but may be part of a different IVF protocol. 

  Frequency: Typically starts mid-stimulation and continues daily until the trigger injection.

3. The Trigger Shot 

Purpose: To finalise egg development and prepare them for retrieval. 

Common Medications:

• hCG (e.g., Ovitrelle) or a combination like Lupron and hCG. 

 Frequency: Given only once, typically 36 hours before the egg retrieval procedure.

4. Progesterone Support After Egg Retrieval 

Purpose: To prepare and support the lining of your uterus for implantation. 

  Common Medications:

• Progesterone-in-Oil (PIO) injections 

  Frequency: Daily, starting after egg retrieval until 10-12 weeks of pregnancy if successful.

Many clinics are now offering progesterone alternatives like vaginal suppositories or tablets, so you might not need ongoing injections for this phase.

The total number of injections typically falls within the 20-60 range across a single IVF cycle. 

Here’s a quick breakdown by stage (assuming an average IVF protocol): 

• Ovarian Stimulation Medications: 10-28 injections 
• GnRH Antagonist or Lupron Dosages: 5-14 injections 
• Trigger Shot: 1 injection 
• Progesterone Support (if injections are used): up to 30 injections 

Keep in mind these numbers can vary significantly. Some protocols, such as a “mini-IVF” or a natural cycle IVF, might involve fewer medications and injections.

1. Get Comfortable with the Process 

Ask your doctor or nurse to demonstrate the injections for you at your first appointment. Many clinics offer thorough instructions, and some even provide tutorial videos. 

Pro Tip: Mark your calendar with not just the dates of injections but the specific timing for each dose. Timing is critical in IVF treatments. 

2. Use Numbing Techniques 

If you’re anxious about the needle, try numbing the area with an ice pack or numbing cream prior to the injection. It reduces the sting considerably. 

3. Rotate Injection Sites 

Constantly using the same spot can cause soreness and bruising. Rotate between the left and right sides of your abdomen or upper thighs to alleviate discomfort. 

4. Establish a Routine 

Make injecting a predictable part of your day—for example, always in the evening or early morning. This reduces the mental burden of trying to remember when to inject. 

5. Don’t Hesitate to Ask for Support 

If administering shots yourself feels overwhelming, ask your partner, a friend, or a family member to help. It can feel less daunting with support. 

It’s okay—needle fear is more common than you think! Here are a few extra strategies to help you manage it:

• Distract Yourself with music, TV, or deep breathing techniques during injections. 
• Focus on the Goal. Remind yourself that every injection is bringing you closer to your future family. 
• Celebrate Small Wins. Each time you get through an injection, treat yourself to something small—a piece of chocolate, a walk, or even a celebratory sticker on your calendar. 

One thing that surprises many people is how empowering the process can feel after getting comfortable with it.

While the idea of dozens of injections may feel overwhelming at first, each step becomes routine over time.

Parents who’ve gone through IVF often say they felt a sense of pride in how they engaged in this hands-on process to create their family. 

While the number of injections during IVF might sound daunting, breaking it down into stages makes it less overwhelming. Each needle has a purpose, and with every dose, you’re one step closer to achieving your dream.

1.Can you do IVF injections in the thigh?

Yes, IVF injections can be taken in the thigh — but only some types.
Most IVF stimulation injections are subcutaneous, which means they go into the fatty layer under the skin. These can be comfortably given in areas like the abdomen (belly) or the outer thigh.

However, some injections used in IVF are intramuscular, and these are usually given in the buttock muscle, not the thigh, because the muscle in that area provides better absorption.

If you prefer thigh injections, always ask your nurse or doctor which of your prescribed injections are safe to take there. Proper technique and the right injection site ensure the medication works effectively and reduces pain or bruising.

2. Do IVF injections hurt?

Most IVF injections use very thin needles and are given just under the skin (subcutaneous), so the pain is usually mild—a quick pinch or sting. Progesterone-in-oil shots (if used) can feel heavier, but applying ice, warming the oil, or massaging afterward makes them easier.

3. What happens if I miss a dose or forget an injection?

Call your clinic immediately. Missing a dose may affect how your follicles grow. Do not double the next dose unless your doctor clearly tells you to. Timing is important in IVF, so it’s best to set alarms or reminders.

4. Will every woman need progesterone injections after embryo transfer?

Not always. Some clinics use progesterone injections, while others use vaginal gels, suppositories, or oral progesterone. It depends on your uterine lining, hormone levels, and clinic protocol.

5. Why do I need so many injections for IVF?

IVF requires careful control over your hormones. Multiple injections help:

Grow several eggs

Prevent eggs from releasing early

Prepare your uterus

Each injection supports a different stage of treatment.

6. Can the number of injections change during the cycle?

Yes. Your doctor may increase or decrease doses depending on your blood tests and ultrasound scans. Your protocol can change mid-cycle based on how your body responds.

7. What are common side effects of IVF injections?

You may experience:

Bloating

Breast tenderness

Mood swings

Mild abdominal discomfort

Bruising at injection sites
These side effects usually settle once injections stop.

8. What is the “trigger shot” and why is it important?

The trigger shot is the injection that matures the eggs and prepares them for retrieval. It is usually taken exactly 34–36 hours before the egg pickup procedure. Timing must be perfect.

9. Will IVF injections affect my long-term health?

There is no evidence that IVF injections cause long-term harm when used under medical supervision. The hormones used are similar to what your body naturally produces—just in controlled amounts.

10. Can someone else give me the injections if I am scared?

Yes! Many partners learn how to give the injections. You can also visit your clinic’s nursing team daily if needed, or a home nurse can be arranged.

11. Are there oral medicines instead of injections?

Some IVF protocols use oral medications like Letrozole or Clomiphene, but they usually cannot replace injections completely. Oral medicines may reduce the number of injections but not eliminate them.

12. Why do some women need progesterone injections for 10–12 weeks?

Progesterone helps maintain the uterine lining and supports early pregnancy. Because your natural progesterone may drop after egg retrieval, supplementation is needed until the placenta takes over.

13. How do doctors decide which injection protocol to use for me?

Your protocol depends on:

Age

AMH levels

Antral follicle count

Previous IVF response

PCOS or low ovarian reserve

Body weight

Every plan is personalized.

14. Is it normal to feel emotional or stressed during IVF injections?

Yes—completely normal. Hormones + daily injections + the pressure of wanting success can create stress. Many women experience anxiety, irritability, or mood dips. Emotional support, counselling, or support groups can help.

15. What should I expect after I finish all my injections?

After the injection phase, you will:

Undergo egg retrieval

Wait for fertilization and embryo development

Have your embryo transfer (fresh or frozen)

Continue some medications until the pregnancy test

Your clinic will guide you step-by-step through each stage.
