When the husband’s sperms have poor movement or the count is very low, IVF will not work, as the sperms will not be able to enter the eggs. In these situations, ICSI is the only option. This technique is carried out under a very powerful microscope. By means of a very fine needle, each egg is injected with a single sperm. If fertilization and cleavage occur, the embryos are then replaced into the uterus.
ICSI is indicated for:
- Men with low sperm count
- Men with abnormal sperm in terms of genetics, shape, size and motility
- Previously failed IVF because of lack of fertilization.
- Men who have undergone vasectomies that cannot be reversed. In this
case the sperm is harvested through PESA or TeSA.
- Men with erectile dysfunction and/or problems with ejaculation
