title: [Intracytoplasmic injection of spermatozoa].
abstract: Management of male infertility has been totally changed with the development of intracytoplasmic sperm injection (ICSI). This technique, used for in vitro fertilization, consists in injecting a single spermatozoa into the ovum. Intracytoplasmic sperm injection can be proposed in case of severe male sterility (oligoasthenospermia) or after repeated failure of in vitro fertilization. Satisfactory rates of fecondation and pregnancy have been obtained. Results have also been obtained with sperm taken from the epididymis or testis. The risks involved concern the transmission of poorly understood genetic defects leading to the infertility. The rates of reported malformations and chromosome anomalies are quite low. Intracytoplasmic sperm injection can be useful in managing most cases of male infertility which to date have had to rely on donor sperm. Long-term results have not yet been obtained.
