IUI (Intrauterine Insemination)

Intrauterine insemination is also known as artificial insemination. It is a simple and effective process used to treat couples who have fertility issues. The concentrated and washed sperm from a seminal fluid is procured and placed in the lab. With IUI, this sperm is used to penetrate into the egg (cytoplasm) and embryos or egg is fertilized over a period of time.

A hale and healthy sperm are taken out of semen fluid and inserted inside the egg. Sometimes sperm is unable to get into the egg as the eggs’ outer layer is thick and hard to go through. In such conditions, IUI is effective and considered to be a more robust mechanism to cope up with infertility issues.

IVF (In Vitro Fertilization)

IVF is an assisted reproductive technology used for treating infertility problems. The IVF is done outside the woman’s body in a lab where mans’ sperm and the woman’s egg are combined. Before fertilization, the woman is given prescribed medications to stimulate the ovaries to retrieve eggs from fallopian follicles.  

The egg is retrieved by sedating and insemination is carried out on the same day. After fertilization, the embryo or fertilized egg is observed judiciously and decides when to transfer it to the uterus.

After this process, the successfully fertilized eggs or embryos will be planted in the uterus. As a result, a woman conceives a baby.
