Abstract

The introduction of intracytoplasmic sperm injection (ICSI) for severe male cases has made it possible to treat patients with azoospermia, in whom sperm is achieved from the epididymis and the testis (1–3). In some of the treated male patients, especially those with non-obstructive azoospermia, mainly immotile spermatozoa are available. Because it is assumed that the fertilizing potential of testicular sperm is lower (4) and motility is an important predictive factor for successful fertilization (5) it should be questioned whether ICSI perfomed with immotile sperm is justified.
