IVF Injections: What They Are, How They Work, and What to Expect

When people talk about IVF injections, medications used to stimulate egg production during in vitro fertilization. These aren’t just pills—they’re targeted hormone shots that guide your body through the complex steps of fertility treatment. Also known as ovulation induction drugs, they’re the foundation of most IVF cycles, helping doctors control timing, boost egg count, and improve the chances of a successful pregnancy. Without these injections, the body wouldn’t produce enough mature eggs for retrieval, making IVF nearly impossible for many couples.

IVF injections work by mimicking or overriding your natural hormones. You’ll typically start with FSH (follicle-stimulating hormone), a hormone that tells your ovaries to grow multiple follicles. These are often combined with gonadotropins, which include both FSH and LH (luteinizing hormone). Later in the cycle, you’ll get a trigger shot, usually hCG or Lupron, to tell your body to release the eggs. This final injection is timed to the minute because egg retrieval happens just 36 hours later.

It’s not just about the drugs—it’s about the process. Most people give themselves daily injections in the belly or thigh. It sounds scary at first, but with practice, it becomes routine. Side effects like bloating, mood swings, or soreness are common, but they’re temporary. Your clinic will walk you through every step: how to mix the dose, where to inject, how to track symptoms, and when to call for help. Many clinics even offer nurse support lines or video tutorials.

These injections aren’t one-size-fits-all. Doses vary based on age, ovarian reserve, and how your body responds. Some need higher doses; others respond well to lower ones. Your doctor will adjust based on ultrasound scans and blood tests, making it a personalized journey. That’s why sticking to the schedule matters—missing even one shot can throw off the whole cycle.

IVF injections are part of a bigger picture. They connect to your overall fertility health, your emotional readiness, and even your lifestyle. Sleep, stress, nutrition—all of it affects how your body responds. While these shots are medical, the way you care for yourself around them is just as important.
