Due to the influence of economic, social and many other factors, there are more and more reproductive problems. Originally introduced for managing male factor infertility, intracytoplasmic sperm injection had become the most commonly used fertilization treatment in the world, with broadened indications including low oocyte yield, prior fertilization failure with conventional in vitro fertilization etc. However, academic evidence for better live-birth outcomes of intracytoplasmic sperm injection over conventional in vitro fertilization is limited. Thus, we aimed to compare the reproductive outcomes of conventional in vitro fertilization and intracytoplasmic sperm injection in patients with non-severe male factor infertility across poor and different sub-optimal ovarian response categories. The fertility rate, implantation rate, clinical pregnancy rate, live birth rate and other obstetric outcomes were mainly compared. Our results showed that independent of the number of oocytes retrieved, intracytoplasmic sperm injection significantly increased the fertilization rate, while conventional in vitro fertilization cycles showed a higher implantation rate, clinical pregnancy rate, and live birth rate. No differences were observed in most obstetric outcomes. Our study indicates that poor ovarian response is not an indication for intracytoplasmic sperm injection in couples with non-severe male infertility.
