Intracytoplasmic Sperm Injection (ICSI) enables men with poor sperm quality to father children. ICSI is used when the male has a very low sperm count, if sperm motility is poor, or if there is a low percentage of normal shaped sperm. It is used in some cases of unexplained failed fertilization in a prior IVF cycle.
In the ICSI procedure, a microscopic hole is placed in the egg membrane with an instrument that resembles a needle. A single sperm from the male is inserted into the egg.
There is no difference between the offspring produced by ICSI and those conceived by other methods. There is now broad, successful, clinical experience with hundreds of ICSI patients and their children. Embryologists receive advanced training to enable them to perform this delicate procedure.
