ICSI is a micromanipulation technique developed to achieve fertilization. In this procedure a single sperm is injected directly into the cytoplasm of an egg. It is done for couples with severe male factor infertility or when there has been a previous fertilisation failure using conventional IVF. Very few sperms are required for ICSI procedure.
ICSI is carried out in the embryology lab by experienced embryologists using highly specialized equipment.
ICSI technique has helped many couples to conceive using their own eggs and sperms.
