For couples struggling with infertility, In Vitro Fertilization (IVF) offers a path to parenthood. This assisted reproductive technique involves fertilizing an egg with sperm outside the body and transferring the embryo into the uterus. Let’s break down how IVF works step by step from the initial consultation to the moment you wait for that positive pregnancy result.
IVF is one of the most effective fertility treatments designed for couples facing challenges such as blocked fallopian tubes, low sperm count, ovulation disorders, or unexplained infertility. The process combines medical science and timing precision. When natural conception doesn’t occur, IVF treatment replicates the process in a controlled environment.

Understanding how IVF works step by step gives you confidence and clarity before beginning the journey.
Every IVF cycle follows a structured approach. Here’s what each stage involves:
The first step in how IVF works step by step involves stimulating the ovaries to produce multiple eggs. Fertility medications (gonadotropins) help mature more than one egg, increasing the chance of successful fertilization.
During this phase, you’ll undergo:
Once the follicles are ready, a “trigger shot” (hCG injection) prepares eggs for collection.
About 34–36 hours after the trigger shot, eggs are retrieved from the ovaries using a fine needle under light sedation. This short, painless procedure takes around 15–20 minutes. The retrieved eggs are immediately sent to the lab for fertilization. Egg retrieval is crucial in how IVF works step by step, as it ensures the best quality eggs are selected for fertilization.
On the same day, a semen sample is collected. The best quality sperm are selected through advanced techniques.
There are two main fertilization methods:
This stage is the core of how IVF works step by step, as it marks the beginning of embryo formation.
Fertilized eggs are cultured for 3–5 days in a controlled environment. Embryologists observe their growth and select the healthiest embryos. Advanced technologies like Blastocyst Culture or Embryo Grading help determine which embryo has the highest chance of successful implantation. Embryo selection plays a major role in IVF success and defines the quality outcome of how IVF works step by step.
The final and most anticipated step is embryo transfer. A selected embryo is placed into the uterus using a thin catheter. This procedure is painless and does not require anesthesia. After the transfer, patients are advised rest and prescribed hormonal support to help implantation. Two weeks later, a pregnancy test confirms if the cycle was successful.
After the transfer, it’s time to let nature take over. The embryo must attach to the uterine lining to begin pregnancy.
During this stage:
Emotional support is key. At Lifeline IVF, compassionate care continues beyond the procedure, helping couples through the crucial waiting phase.
Success rates of IVF treatment vary depending on age, egg and sperm quality, and overall reproductive health. Typical IVF success rates range between 40%–60% for women under 35. However, several factors can influence results:
Following medical advice, maintaining a healthy diet, and choosing an advanced fertility center like Lifeline IVF can significantly improve success chances.
At Lifeline IVF, we provide personalized care and advanced reproductive technology to help every couple achieve their dream of parenthood.
Our IVF treatment includes:
Each IVF journey is unique, and our team ensures that every step from consultation to embryo transfer is handled with utmost care and accuracy.
A full IVF cycle typically takes 4–6 weeks, depending on your body’s response to medication.
The procedures are mostly painless and done under light sedation. You might experience mild discomfort post retrieval.
Usually, 1–2 embryos are transferred based on age, medical history, and embryo quality.
A blood test is done around 14 days after embryo transfer to confirm pregnancy.
