OBJECTIVE: This study compared the outcomes of conventional in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in patients with polycystic ovarian syndrome (PCOS), tubal factor (TF) infertility, and unexplained infertility whose partners had normal semen parameters.
METHODS: This retrospective study included 360 couples diagnosed with infertility involving PCOS (n=157), unexplained infertility (n=140), and TF infertility (n=63). Sibling oocytes were randomly assigned to undergo ICSI or conventional IVF insemination. The fertilization rate and embryo morphology were evaluated as outcomes.
RESULTS: Retrieved cumulus-oocyte complexes from patients with PCOS (2,974), unexplained infertility (1,843), and TF infertility (844) were split and inseminated by conventional IVF and ICSI respectively. In comparison to the ICSI method, the conventional IVF approach was linked to a significantly higher fertilization rate in groups with PCOS (68.81% vs. 77.49%), unexplained infertility (67.62% vs. 78.84%), and TF issues (69.23% vs. 78.63%) (p<0.05). The proportion of embryos with grade A produced by the conventional IVF method was significantly higher than that produced using the ICSI method in the PCOS and unexplained infertility groups (p<0.05). Additionally, the percentage of grade B embryos produced with the ICSI method was significantly higher than that produced with the conventional IVF method in PCOS patients (p=0.002).
CONCLUSION: Our results indicated that the conventional IVF method was associated with higher zygote production and a higher proportion of grade A embryos when all infertile groups were evaluated together. Thus, ICSI is not suggested for patients with these causes of infertility if their partner has normal semen parameters.
