Intracytoplasmic sperm injection (ICSI) has enhanced the treatment of male factor infertility. It differs from traditional in vitro fertilization (IVF). Instead of mixing much sperm with an egg in a dish, the embryologist selects a single sperm and manually injects it immediately into the egg to initiate fertilization. Naturally, the fertilization system includes the penetration of a single sperm from the ejaculate into the egg (known as oocyte in clinical terms) released throughout the menstrual cycle. Said sperm must enter the shell of the oocyte (known as zona pellucida) to fuse with the female gamete immediately.

ICSI Treatment Process
With regular IVF, the woman will first want to take fertility medication to stimulate the production of eggs in the ovaries. During this time, the physician will display the development of the eggs. The ICSI method is completed while the egg is prepared to be retrieved.
- Step 1: Retrieval
- Step 2: Inject of Sperm into Egg
- Step 3: Analyze the Embryo
- Step 4: Transfer of Embryos
The man should produce a sperm sample ejaculating right into a cup, or the sperm will surgically be retrieved. There are some exceptional methods the sperm can be retrieved. In a few cases, the sperm retrieval method can complete earlier, and the sperm can be frozen.
It is injected into an egg with an excellent hollow needle. However, the sperm is injected directly; it bypasses swimming through the cervical fluid. It will take a sperm more than 24 hours to fertilize an egg and build an embryo.
The fertilized embryos are stored in a lab for more than six days. During this time, they are checked for signs of increase and development. Not all fertilized embryos could be transferred to the female's uterus. Hence this step is vital to choosing the healthiest and most viable embryos.
Embryo transfer is an important step in IVF treatment because it helps to determine which embryo will be transferred. The decision is made based on the quality of the embryo and its viability, as well as how many embryos are available for transfer.
