The first-generation IVF technique involves collecting both egg cells and sperm and placing them in a laboratory dish where fertilization can occur naturally. If fertilization is successful, an embryo may form. The tiny embryo (about 0.1 millimeters in size) is then transferred into the uterus using a soft, thin tube. If the embryo successfully implants and develops, a baby will be born nine months later.

How does it work?

Step 1: Ovulation Induction
Medications are used to stimulate the ovaries to produce multiple follicles. This can involve oral medications, injections, or a combination of both. The doctor will design a personalized stimulation plan based on the patient’s individual condition.

Step 2: Egg Retrieval
The eggs are collected from the ovarian follicles and placed into a test tube.

Step 3: Sperm Collection
On the same day, the husband provides a semen sample, which is then processed in the laboratory. A laboratory technician selects the best sperm under strict conditions.

Step 4: Fertilization and Embryo Culture
The embryologist mixes the eggs and sperm in the lab, allowing natural fertilization to occur, and the embryos are cultured for 3 to 6 days.

Step 5: Embryo Transfer
A reproductive specialist transfers one or two embryos into the uterus. Any remaining embryos can be frozen for future thawing and transfer.

Step 6: Pregnancy Test
After two weeks, a blood test is conducted to check if pregnancy has been achieved.

Tips: During a single ovulation induction cycle, the doctor aims to retrieve as many eggs as possible to form an appropriate number of embryos, maximizing the chances of a successful pregnancy.
