Improvement in biochemical manifestations of the serum and follicular fluid and ICSI outcomes in PCOS patients with myo-inositol administration: prospective randomized research.

Abstract

The research investigated the capacity of myo-inositol (MI) in order that it improves biochemical markers in serum and follicular fluid and, ultimately, intracytoplasmic sperm injection (ICSI) outcomes of women with PCOS. Sixty infertile patients with PCOS, who were undergoing ovulation induction for ICSI, were randomly divided to two groups. The MI group received 2000 mg myo-inositol + 1 mg folic acid twice a day for 6 weeks with starting the ICSI cycle. For the same period, the control group received a placebo containing only folic acid (1 mg). Levels of hormonal profiles in serum and follicular fluid, as well as oxidative stress markers (MDA, TAC, GPx, and SOD), were estimated using an ELISA assay. Primary end points were ICSI cycle outcomes. Compared to the placebo group, the MI group demonstrated significant reduction in serum and follicular fluid levels of LH, LH/FSH ratio, total testosterone, AMH, and androstenedione. Furthermore, the MI group exhibited meaningful increases in TAC, GPx, and SOD, but MDA significantly decreased. While the number of retrieved and mature oocytes is not statistically similar among the groups, the MI group showed significant improvements in the percentage of immature oocytes, cleavage rate, and good embryo quality. A meaningful correlation was checked between follicular fluid AMH level and LH, FSH, total testosterone, androstenedione, insulin, MDA, the number of retrieved oocytes, and immature oocytes. Our outcomes indicate that myo-inositol administration in women with PCOS undergoing ART helps to improve their hormonal profiles, and the quality of oocytes and embryos.
