Since its first successful use in 1978, In Vitro Fertilisation (IVF) has become a routine medical procedure that has resulted in thousands of births. IVF is the most effective and common form of assisted reproductive technology (ART).
IVF is particularly helpful for women of advanced age, women with damaged fallopian tubes or endometriosis, as well as male infertility.
IVF is simply the combination of a man’s sperm and a woman’s egg in the fertilisation process. The major difference is in where this process takes place. Instead of happening in the fallopian tubes, fertilisation takes place in the laboratory in a nurturing environment that mimics natural conditions.
IVF involves extracting a woman’s eggs, fertilising the eggs in the laboratory, and then transferring the resulting cultured embryos into the woman’s uterus through the cervix.
A Cycle’s flow
At LaVida Advanced Fertility and Genetics Center, the IVF process is characterised by four different stages :
- The first step is to stimulate the ovarian follicles into producing a larger quantity of unfertilised eggs. This can be accomplished using fertility medications that boost a woman’s reproductive cycle into producing more than one egg. If “Natural IVF” treatment is chosen, this first step of taking medication is skipped. “Minimal Stimulation IVF” uses low doses of medication to stimulate egg production.
- Next, IVF doctor uses ultrasound guidance to navigate into the ovaries and collect the newly matured eggs. This follicular aspiration is done via outpatient surgery, with eggs and fluid removed by a suction needle from each of the woman’s follicles.
- Third, after being identified and removed from their natural follicular fluids, the eggs are fertilised and allowed to form in an incubator. Most eggs are simply fertilised by being in close proximity to healthy sperm, with nature doing the rest. Usually, fertilised eggs divide on a cellular level and form embryos within three to five days. On Day 5 or Day 6, these embryos become blastocysts. These healthier and more stable blastocysts provide you with the greatest possible chance of pregnancy—while reducing the risk of multiple births. While blastocyst transfer is ideal, in some circumstances Day 3 to Day 5 transfer is performed to optimise chances of success.
- Finally, once the embryos are ready, they will be reintroduced to the cervix, where the natural gestation process takes over. More than one embryo can be placed back into the uterus, increasing the chances of pregnancy.
In addition to the expertise of our top fertility doctors, our Laboratory embryologists use highly effective micro-manipulation techniques such as ICSI to further increase your chances of success.
