In vitro fertilisation (IVF) is a complex, yet one of the most effective assisted reproductive technologies that helps many couples become parents. Despite its popularity, the IVF process often remains unclear or even intimidating to many. To dispel myths and confusion, here’s a detailed explanation of how IVF works, what stages it includes, and what to expect at each step.
What is IVF?
IVF is the process of fertilising an egg with sperm outside the woman’s body. The fertilised egg (embryo) is cultured in a specialised laboratory environment and then transferred into the woman’s uterus in hopes of achieving pregnancy.
IVF is commonly used when natural conception is impossible or unlikely — for example, in cases of blocked fallopian tubes, endometriosis, male infertility, unexplained infertility, or age-related factors.
The IVF process step by step
- Step 1: Initial consultation and diagnostics
The journey begins with a consultation with a fertility specialist. The couple undergoes comprehensive testing: hormonal panels, ultrasound, semen analysis, and genetic screening (if needed). Based on the results, the doctor develops a personalised treatment plan.
- Step 2: Ovarian stimulation
The woman receives hormone therapy to stimulate the ovaries to produce multiple eggs — instead of the single egg that typically matures in a natural cycle. This phase lasts approximately 10–12 days and includes regular monitoring of follicle growth via ultrasound and lab tests.
- Step 3: Egg retrieval (oocyte pick-up)
When the follicles reach optimal size, the eggs are retrieved using a minimally invasive procedure guided by ultrasound. The procedure is short, performed under light sedation, and is generally painless.
- Step 4: Fertilisation in the lab
The retrieved eggs are fertilised with sperm from the partner (or a donor). This can be done through conventional IVF or ICSI (intracytoplasmic sperm injection), where a single sperm is injected directly into the egg. The fertilised eggs become embryos and are cultured in an incubator for 3–5 days under close supervision.
- Step 5: Embryo transfer
One high-quality embryo is selected and transferred into the uterine cavity. The procedure is painless, does not require anaesthesia, and takes only a few minutes. Any remaining viable embryos can be cryopreserved for future use.
- Step 6: Support and the two-week wait
After the transfer, the patient receives hormonal support to maintain a receptive endometrium and promote implantation. After 10–14 days, an hCG blood test is performed to determine whether pregnancy has occurred.
How many IVF attempts may be needed?
While IVF is highly effective, success is not guaranteed on the first attempt. The chances of pregnancy depend on many factors, including age, egg and sperm quality, endometrial condition, and other health concerns. In some cases, it may take two or three cycles to achieve pregnancy. However, modern technologies — such as preimplantation genetic testing (PGT), cryopreservation, and improved embryo culture systems — significantly boost success rates.
