Abstract
OBJECTIVE: To present a complete results of Intracytoplasmic Sperm Injection Program (ICSI) performed at IVF Unit in Bialystok, Poland. DESIGN: Retrospective data analysis. MATERIALS AND METHODS: A total of 2593 cycles of ICSI treatment were analyzed. The results of controlled ovarian hyperstimulation (COH), parameters of fertilization, early embryo development and clinical pregnancy rates were compared depending on the type of COH used. RESULTS: Overall, for 16708 MII oocytes microinjected, the 2 pronuclear fertilization rate was 54%. Embryo transfer was performed in 94% of started cycles and 629 clinical pregnancies were recorded, giving a clinical pregnancy rate of 24% per cycle and 26% per transfer. No influence of COH on embryological and clinical results was noted. CONCLUSION: Intracytoplasmic sperm injection can be used successfully to treat couples with male factor infertility and those who have failed standard IVF. Precisely adapted protocol of ovarian hyperstimulation for every patient could diminish the costs of treatment without negative influence on ICSI results.
