The role of sperm parameters on ICSI success [Sperm parametrelerinin ICSI başarisindaki rolü]

Introduction: In this study, we aimed to investigate the relation between the sperm parameters and fertilization and pregnancy rates in intracytoplasmic sperm injection (ICSI) method which is applied to infertile couples. Materials and Methods: Four hundred thirty six couples who applied to Ege University Family Planning and Infertility Research and Treatment Center between January 2000 and January 2002 period were enrolled to the study. Infertile couples of males were evaluated by physical examination, spermiogram and hormone profile. Sperm morphologies were evaluated with Kruger criteria. Results: One hundred twenty two of 493 infertile males (24.74%) had oligozoospermia, 59 of them had asthenozoospermia (11.96%), 67 of them (13.61%) had teratozoospermia and 188 of them oligoasthenozoospermia (38.13%). For the statistical analysis, 57 (11.56%) infertile patients with normal sperm parameters were considered as the control group. The fertilization rates were as follows: 70.9% in oligozoospermic group, 72.8% asthenozoospermic group, 67.4% in teratozoospermic group, 66.7% oligoasthenozoospermic group and 79% for the control group. (p=0.27) Pregnancy rates in oligozoospermic group was 41.3%, in asthenozoospermic group was 43.9%,in teratozoospermic group 35.9%, in oligoasthenozoospermic group was 46.4% and for the control group was 49.1% (p=0.632). Conclusion: We did not see any difference between the disorders of sperm parameters oligozoospermia, asthenozoospermia, teratozoospermia, oligoasthenozoospermia. ICSI seems to be a successful method in the treatment of male infertility
