Abstract
To investigate the role of in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) in cases with isolated teratozoospermia, and to provide reference for infertile patients to choose a reasonable insemination program. From January 2018 to December 2022, 433 couples received assisted reproductive assistance in the Department of Reproductive Medicine of our hospital. Among them, 81 patients presented isolated teratozoospermia (other sperm parameters were normal). These underwent IVF/ICSI, and differences in embryological data were compared between groups. 60 patients with moderate teratozoospermia went IVF, 11 needed rescue ICSI (R-ICSI, 18.33%), and 49 developed up to the blastocyst stage. 14 patients with severe teratozoospermia went IVF, 2 needed R-ICSI (14.29%), and 12 developed up to the blastocyst stage. There were no statistically significant differences in the proportion of R-ICSI between the two groups. Embryological outcomes were not significantly different between groups. The present results suggest that patients with moderate and severe teratozoospermia can be effectively treated with IVF, being R-ICSI performed when necessary.
