In Vitro Fertilisation Process is where eggs are collected from the o***y, fertilised with s***m in the laboratory and replaced back into the uterus, hopefully generating a successful pregnancy.
At Lagos IVF the majority of our patients under a short-cycle IVF treatment known as an Antagonist Cycle. On average the Antagonist Cycle time frame from a patient telephoning with their period to pregnancy test is approximately 4 weeks. This treatment is better for women because it is less stressful, it has fewer side effects and is much quicker, so couples see results earlier.

What happens during the IVF Process:
Step 1 – Egg Collection
The starting point of the IVF process is obtaining eggs from the ovaries. This is done by administering injections of FSH (Follicle Stimulating Hormone), which encourages the development of several follicles (sacs on the ovaries that contain eggs). There are usually 5 – 10 sacs, however the number can vary immensely. This process normally takes about two weeks. Once enough follicles have developed, the eggs are removed from the ovaries by passing a needle into the fluid filled sacs that contain the eggs (follicles) and aspirating them out. This is a simple procedure that is performed in theatre by a doctor under a light anaesthetic.
Step 2 – S***m Preparation
While the eggs are being collected in theatre, the semen sample is also being prepared. Depending on the quality of the semen sample there are different preparation methods that can be performed, however the most common method is called a density gradient preparation. The semen is added to a test-tube that contains a special media, which filters out s***m that have poor motility. If the s***m count isn’t ideal, or if the man has had a surgical s***m collection, the s***m sample will be spun to concentrate as many s***m together as possible. These samples are then used to inseminate the eggs.
Step 3 – Insemination
There are two different types of insemination techniques. IVF standard insemination or ICSI (Intracytoplasmic S***m Injection). IVF standard insemination is used in patients that have normal s***m parameters and this involves the scientist in the laboratory placing the eggs and the s***m into a dish and leaving them overnight so that fertilisation can occur. If there are severe problems with the s***m, or if IVF standard insemination has failed previously, IVF is combined with ICSI, where scientists inject a single s***m into each egg. These are then also left overnight in the hope that fertilisation will occur.
Step 4 – Fertilisation
The morning after the egg retrieval, the scientists check the eggs for signs of fertilisation. If normal fertilisation has occurred the fertilised eggs are now called ‘embryos’ and are grown in the laboratory until they are ready to be placed back into the uterus.
Step 5 – Embryo Culture
Embryos can be grown in the laboratory for up to six days after egg retrieval. They can be replaced back into the uterus at a variety of stages depending on what you have decided with your doctor. At Lagos IVF, we offer two different stages of embryo culture and transfer, either ‘cleavage stage’ or ‘extended/ blastocyst stage’. Cleavage stage is the term used for either day two or day three embryo culture and transfer. This is beneficial for couples that hav
