If poor sperm quality is the problem, fertilization of the eggs cannot be expected by the regular IVF procedure. In such situations we perform ICSI (Intra Cytoplasmatic Sperm Injection), where one single sperm cell is introduced into the egg by a special technique. ICSI is also performed in cases where prior IVF treatments fail to fertilize the eggs despite of a normal sperm quality.
The ICSI technique has been performed for several years with success and today more than 60,000 children have been born following ICSI treatment. Careful examination of these children has not demonstrated any increased incidence of chromosome abnormalities or malformations.
