Hosseini SH, Sabbaghian M, Meybodi AM, et al. - In this research, the intracytoplasmic sperm injection (ICSI) outcomes of infertile men with severely short tail sperm defects were explored. Researchers enrolled a total of 117 infertile men with primary infertility. The effect of short tail sperm defect on large ICSI series (228 cycles) outcomes was assessed. The outcomes imply that ICSI should be considered as a proper treatment way for infertile men with severe short tail sperm defect and probably other sperm flagella abnormalities.
