Why Medications Are Used in IVF

If you're starting your IVF journey, one of the first things you’ll encounter is a list of medications prescribed by your fertility specialist. While this might seem overwhelming at first, each medication plays a critical role in preparing your body for success during every step of the IVF process.
The Purpose of IVF Medications
IVF medications are carefully designed to work with your body’s natural hormonal system, but with greater control and precision. Here’s what they help with:
• Preparing Your Body for Egg Development and Fertilization
In a natural menstrual cycle, a woman typically produces just one mature egg. However, during IVF, we aim to retrieve multiple mature eggs to increase the chances of fertilization and a successful pregnancy. IVF medications help stimulate the ovaries to develop several follicles, each potentially containing an egg.
• Regulating Ovulation and Improving Egg Quality
Timing is everything in IVF. Medications help control when your body ovulates to ensure that eggs are not released too early. This regulation allows fertility experts to retrieve mature eggs at the optimal time. Additionally, hormone support during the cycle creates a better environment for egg growth and quality.
• Increasing the Chances of Successful Implantation
After fertilization, the embryo needs a receptive uterine lining for implantation. IVF medications—especially progesterone and estrogen supplements—help prepare the uterus to be in the best possible state to accept the embryo and support early pregnancy.


How IVF Medications Fit into the Treatment Timeline

IVF is a step-by-step process, and medications are introduced at different stages, each with a specific purpose. 
Here's a breakdown of how they fit into the IVF treatment timeline:
  • Suppression - To prevent early ovulation, ensure eggs aren’t released before retrieval
    At the beginning of the cycle, your body’s natural hormone signals are suppressed using medications like GnRH agonists or antagonists. This prevents your body from ovulating on its own and helps us time the egg retrieval precisely.
 
  • Stimulation - To stimulate the ovaries to produce multiple follicles and mature eggs
    Once suppression is achieved, you’ll begin stimulation injections—typically FSH or HMG-based medications, to grow multiple follicles. This phase is closely monitored with ultrasounds and blood tests to track follicular growth.
 
  • Trigger - To mature the eggs fully and prepare them for retrieval at the right time
    When your follicles are mature, a trigger injection (usually hCG or similar) is given to complete egg maturation. This medication mimics your body’s natural LH surge and gets your eggs ready for collection.
 
  • Support - To support the uterine lining and improve chances of successful embryo implantation
    After embryo transfer, your body is supported with progesterone and sometimes estrogen. These hormones help create a uterine lining that’s ideal for implantation and early pregnancy support.

That’s why our experts provide personalized guidance, hands-on training, and round-the-clock support to make this journey as smooth and successful as possible.
 


List of Common IVF Medications & Their Effects

IVF isn’t just about lab work and embryo transfers—it’s also about carefully timed medications that help guide your body through every step of the fertility process. These medications play a critical role in improving success rates and ensuring your body is ready at each stage. Let’s explore the most commonly used IVF drugs and their specific roles in your journey.
1. Ovarian Stimulation Medications
These are the first major medications introduced in your IVF cycle. Their goal is to help your ovaries produce more eggs than usual, increasing the chances of a successful fertilization.
Common Medications:
  • Gonal-F (follitropin alfa)
  • Follistim (follitropin beta)
  • Menopur (menotropins)
  • Bravelle (urofollitropin)
How They Work: These medications are synthetic forms of FSH (Follicle Stimulating Hormone) and sometimes LH (Luteinizing Hormone)—the same hormones your body naturally produces to grow eggs. By boosting these hormones, your ovaries are encouraged to develop multiple follicles instead of just one.
Possible Side Effects:
  • Bloating and abdominal discomfort
  • Mood swings or irritability
  • Mild soreness or bruising at injection sites
  • Mild Ovarian Hyperstimulation Syndrome (OHSS)—a condition where the ovaries become swollen and painful due to overstimulation. (Your doctor will closely monitor your hormone levels and follicles to minimize this risk.)
At Isha Women’s Hospital, Dr Chinmay Pataki customises stimulation protocol as per individual hormone profile to maximise safety and success.


2. Ovulation Suppression Medications

Once your ovaries start producing multiple follicles, it’s crucial to control the timing of ovulation. These medications help prevent your body from releasing the eggs too early.
Common Medications:
  • Lupron (leuprolide acetate) – GnRH agonist
  • Ganirelix acetate
  • Cetrotide (cetrorelix) – GnRH antagonists
How They Work:
These drugs temporarily block the LH surge, which is your body’s natural trigger for ovulation. By doing so, your fertility specialist can schedule your egg retrieval at the optimal moment—when the eggs are mature but still within the ovaries.
Possible Side Effects:
  • Mild headaches
  • Hot flashes
  • Nausea
  • Redness or itching at the injection site
These medications are usually introduced mid-way through your stimulation cycle.


3. Trigger Shots (hCG Injections)

The trigger shot is one of the most time-sensitive medications in the IVF process. It plays a key role in helping your eggs mature right before retrieval.
Common Medications:
  • Ovidrel – recombinant hCG
  • Pregnyl and Novarel – urinary-derived hCG
How They Work:
Trigger shots mimic the body’s natural LH surge, signaling your follicles to release mature eggs. This prepares them for collection during the egg retrieval procedure.
Timing is Critical:
This injection must be given exactly 36 hours before your scheduled egg retrieval. Administering it too early or too late can affect egg quality or result in missed ovulation.
 Possible Side Effects:
  • Breast tenderness
  • Abdominal cramping
  • Mood changes
  • Temporary bloating
Your IVF nurse will give you detailed instructions on when and how to administer your trigger shot to avoid any timing errors.


4. Progesterone & Hormonal Support

After your embryo transfer, your body needs help maintaining a receptive uterine lining. That’s where progesterone support comes in.
Common Medications:
  • Crinone – vaginal gel
  • Endometrin – vaginal suppository
  • Progesterone in oil – intramuscular injection
How They Work:
Progesterone prepares the endometrium (uterine lining) to support embryo implantation and early pregnancy. Your body may not produce enough progesterone naturally during IVF, so supplementation is essential.
Available Forms:
  • Vaginal gel or suppositories – localized, easy to use
  • Injections – given into the gluteal muscle, typically once daily
Possible Side Effects:
  • Fatigue
  • Bloating
  • Vaginal discharge (with suppositories or gel)
  • Breast tenderness
  • Emotional sensitivity or mood swings
Progesterone support often continues for 8–10 weeks after embryo transfer if pregnancy occurs.


Managing IVF Medication Side Effects

While IVF medications are a powerful tool in the journey to parenthood, they can come with their own set of physical and emotional challenges. The good news? Most side effects are manageable with the right strategies—and you don’t have to go through it alone.
Let’s take a closer look at how to cope with common IVF medication side effects, helpful tips for first-timers, and important financial guidance.
Common Side Effects & How to Deal with Them
Every woman responds differently to IVF medications. Some may experience very mild symptoms, while others may feel more pronounced effects. Here's what to expect—and how to manage it:
1. Bloating & Cramping: These are common, especially during the ovarian stimulation phase.
What helps:
  • Drink plenty of water to reduce fluid retention.
  • Include light physical activity like walking or yoga to keep blood flowing.
  • Use a warm heating pad on your lower abdomen (avoid during the two-week wait unless advised by your doctor).
2. Emotional Ups and Downs: Hormonal changes can lead to mood swings, anxiety, or tearfulness.
What helps:
  • Journaling your thoughts or emotions each day.
  • Talking to a therapist or counselor who understands fertility treatments.
  • Joining an IVF support group—online or at your clinic—for shared experiences and encouragement.
3. Bruising or Irritation at Injection Sites: This can happen with daily shots, especially if using the same spot repeatedly.
What helps:
  • Rotate injection sites—switch between thighs, abdomen, and buttocks.
  • Apply an ice pack before the shot to numb the area, and a warm compress afterward.
  • Use a gentle massage after injecting to improve absorption and ease discomfort.
When to Call Your Doctor
While mild side effects are expected, certain symptoms need immediate attention:
  • Signs of OHSS (Ovarian Hyperstimulation Syndrome): rapid weight gain, severe bloating, difficulty breathing, or abdominal pain.
  • Allergic reactions: rash, itching, swelling at the injection site, or difficulty breathing.
  • Severe mood disturbances or depression.
Your safety comes first—never hesitate to contact the Isha Women’s Hospital team if something doesn’t feel right.
