How Many Injections Are Required For IVF Treatment?


In Vitro Fertilization (IVF) is an assisted reproductive technology that helps couples conceive a child when natural fertility methods have not succeeded. It involves the introduction of a mature egg and sperm in a laboratory dish, which is then placed in the woman’s uterus at the appropriate time for implantation. During the time of implantation and hormone replacement therapy, IVF is important because it can increase the woman’s chances of becoming pregnant by up to 30-35%.

IVF Treatment may also be used for gender selection, as well as to help couples who have had difficulty conceiving due to fertility issues such as advanced maternal age or blocked fallopian tubes. It is the most widely used type of assisted reproductive technology worldwide.

How Many Injections Are Required for IVF Treatment?

The number of injections required for IVF treatment varies from patient to patient. Some patients may only need a few injections, while others may need up to 90 injections. The number of IVF injections depends on a number of factors, including the patient’s age, ovarian reserve, and the protocol used by the IVF clinic.

Common Types of IVF Injections Used in IVF Treatment

The question of how many injections are required for IVF treatment can be quite daunting for prospective patients. Fortunately, there is a protocol that many clinics follow, and this protocol consists of three primary injections for most IVF treatments that are Gonadotropins, hCG, and Progesterone. Depending on the individual patient’s biology, some may require additional injections beyond the initial three primary injections. However, the protocol has been used successfully for many patients and is an important step in the IVF process.

A. Gonadotropins

Gonadotropins are hormones responsible for releasing mature eggs from the ovaries during ovulation. The most commonly used gonadotropins are follicle-stimulating hormone (FSH) and luteinizing hormone (LH). FSH is prescribed to increase the number of eggs produced by the ovaries, while LH helps to facilitate ovulation. When administering gonadotropins, the typical dosage begins with a low dose and increases gradually until the egg follicles reach a mature size. Some patients may require additional FSH or LH after ovulation has been triggered. The number of doses required will depend on the patient’s individual biology.

B. Human chorionic gonadotropin (hCG)

hCG is a hormone produced by the cells of an implanted embryo. After egg retrieval, patients are usually given hCG to stimulate ovulation of the remaining eggs and ensure successful implantation of the embryos. hCG is typically administered as one single intramuscular injection approximately 36 hours before the embryo transfer and is often given on the same day as the egg retrieval.

C. Progesterone

Progesterone is a hormone necessary for maintaining a viable pregnancy. It helps to prepare and enhance the uterine lining for the successful implantation of the embryo. Progesterone is usually prescribed as an intramuscular injection or vaginally as a suppository once daily from the day of egg retrieval until 12 weeks of pregnancy.

Factors That Affect the Number of IVF Injections Required

The number of injections required during an In Vitro Fertilization (IVF) cycle is largely dependent on the woman’s individual medical characteristics and the type of treatment being used. The following factors all affect the number of injections that may be required in an IVF treatment cycle:

1. The woman’s age

Generally speaking, the older a woman is, the more eggs she will need to have retrieved for a successful IVF cycle. Older women are more likely to require more injections due to the potential need for more than one egg retrieval.

2. The woman’s ovarian reserve

The retrieval of healthy eggs from a woman’s ovaries is strongly linked to her ovarian reserve. A woman with a higher ovarian reserve will generally require fewer injections due to the greater chances of success.

3. The woman’s medical history

If a woman has a complicated medical history or has struggled with infertility, her doctor may recommend that she have more injections than normal. This can ensure that the best possible outcome is achieved.

4. The type of IVF treatment being used:

The type of IVF treatment being used can also affect the number of injections required. For example, the use of donor eggs may require fewer injections as this technique relies on a pre-fertilized egg being used.

Side Effects of IVF Injections

The side effects of IVF injections can vary from patient to patient. Some common side effects include:

  1. Pain at the injection site
  2. Swelling at the injection site
  3. Redness at the injection site
  4. Bruising at the injection site
  5. Fatigue
  6. Mood swings
  7. Headaches
  8. Nausea
  9. Vomiting

Tips for Managing IVF Injections

There are a number of things that women can do to manage the side effects of injections including:

1. Warming the Medication before Injecting It

Warming the medication before injecting it can help make the injection process more comfortable by making the medication less viscous, which can make it easier to inject. To warm the medication, place it in a cup or bowl of warm water for at least a few minutes before injecting it.

2. Applying a Cold Compress to the Injection Site After Injecting It

To help reduce any pain or swelling at the injection site, hold a cold compress to the area for a few minutes after injecting the medication. This can provide relief and help reduce any bruising.

3. Taking Over-the-Counter Pain Medication

Over-the-counter pain medication like acetaminophen is often used to help manage the pain or discomfort associated with injections. However, if you are taking any other medications, always talk to your doctor or pharmacist before taking any over-the-counter medications, as there may be potential drug interactions.

4. Talking to Their Doctor About Other Ways to Manage the Side Effects

Many people experience some degree of pain or discomfort when receiving an IVF injection. Your doctor can provide advice on how to best manage any potential side effects. They may also be able to suggest alternative methods of administering the medication that can help reduce the discomfort. Additionally, your doctor can provide advice on how to best manage any additional side effects that may occur.


If you are considering IVF treatment, it is important to be aware of the potential for a lengthy and challenging process, as well as the number of injections that could add to the stress of the experience. However, IVF injections are essential to increasing the chances of a successful result, and therefore should not be neglected. Be sure to consult your IVF Specialist at your IVF Centre about the number of injections that you can expect to receive, any potential side effects, and how to manage them.
