Objective: To evaluate the IVF outcomes of conventional insemination for less severe teratozoospermia (LST) patients (sperm morphology >2% and <4% normal forms and total motile sperm count ≥10 × 106) and normal sperm patients defined by WHO criteria 2010 in the interest of reducing intracytoplasmic sperm injection (ICSI) rate in IVF. Materials and methods: In this retrospective study, a total of 330 patients were recruited in the conventional IVF insemination. Among them, there were 76 patients in LST group and 254 patients in the normal sperm group. Fertilization rate, abnormal fertilization rate, embryo quality, implantation rate, chemical pregnancy rate, clinical pregnancy rate, abortion rate and live birth rate were assessed. Results: N...
