ICSI is a procedure where one sperm is directly injected into one egg to fertilize it.

This process is commonly used to overcome male infertility problems; it may also be used when eggs cannot be easily fertilized by sperm. The fertilized egg will be developed to an embryo then transferred back into the woman’s uterus.

The embryos are frozen at a cryogenic temperature of -196⁰C and stored at this temperature until it’s needed. The Transfer of these embryos to the uterus will be performed after thawing.
