Comparing antioxidant enzyme levels in follicular fluid in ICSI-treated patients

Conclusions The rate of embryo development decreases with age. In early perimenopause, SOD levels increase, while catalase levels decrease. Additionally, in early perimenopause, SOD activity shortens the time in which 4-cell stage is achieved, while catalase activity delays the 5-cell and blastocyst stages. The quality of embryos has no association with catalase concentration. SOD concentration is associated with the good quality of embryo on the second day of development. The quality of blastocyst in patients in the early perimenopausal age is dependent on SOD concentration. However, the most important prognostic factor of pregnancy after ICSI is age.
