[Outcomes of assisted reproductive technology for patients with different types of teratozoospermia]

To discuss the outcomes of ICSI in infertile patients with globozoospermia (GS), acephalic spermatozoa syndrome (ASS) or teratozoospermia with miniacrosome and irregular-headed sperm defect (TMRHS).

This retrospective study included 3 cases of GS, 3 cases of ASS and 2 cases of TMRHS undergoing ICSI. We analyzed the rates of fertilization, cleavage, blastocyst formation, implantation, clinical pregnancy and live birth in the three groups of patients.

The patients of the GS and ASS groups all achieved clinical pregnancies and healthy births, but those of the TMRHS group showed a lower fertilization rate than the other two groups and achieved no clinical pregnancy.

ICSI could achieve successful clinical pregnancy in infertile patients with globozoospermia or acephalic spermatozoa syndrome, but no satisfactory clinical outcome in those with miniacrosome and irregular-headed sperm defect, though it has to be further proved by more studies with larger-sized samples.
