Abstract
The study is retrospective to compare ICSI outcome of patients with cryptozoospermia or severe oligozoospermia after use of ejaculated versus extracted testicular sperms in different cycles for the same patient. The study was carried out on couples who underwent ICSI in period 2012-2014 for male factor infertility.Patients with semen showing cryptozoospermia were candidates for inclusion in this study. First cycle was done as ICSI with priority to ejaculated sperm; testicular sperm was used if no motile sperm was available. For failed cases a second cycle was repeated using either testicular sperm or ejaculated sperm. Among 9934 infertile patients only 430 were belonging to this category according to ADAM International Hospital’s database. Among 430 cryptozoospermic patients 36 couples underwent repeated (2or3 trials) ICSI in ADAM International Hospital. The different cycles was compared as regards fertilization, embryo quality, embryo transfer, implantation rate, abortion rate and pregnancy rate. The study showed that ejaculated spermatozoa recovered from patients with cryptozoospermia were as much effective as testicular spermatozoa on ICSI cycles outcomes. We concluded that in patient with severe male factor or cryptozoospermia, priority is to use ejaculated sperm rather than testicular sperm
