Abstract

Objective: To evaluate the outcomes of IVF and the follicular fluid metabolomic profile in patients with predicted poor ovarian response who received myo-inositol (MI) 1200 mg, alpha-lactalbumin (α-LA), and folic acid 400 mcg at the preconception stage.

Materials and methods: The study included 80 women with a predicted poor ovarian response, belonging to groups 3 and 4 of the POSEIDON classification, who were planning to undergo IVF as part of their infertility treatment. Patients in group 1 received MI 1200 mg, α-LA, and folic acid 400 mcg (Inofert Forte) daily for three months before ovarian stimulation. The women in group 2 received 400 mcg of folic acid. Amino acid and ceramide levels in the follicular fluid were analyzed.

Results: Group 1 showed a significant increase in the number of mature oocytes, zygotes, total blastocysts, and good-quality blastocysts compared with group 2. The use of MI + α-LA resulted in a statistically insignificant increase in the clinical pregnancy rate (27.0% in group 1 versus 10.8% in group 2, p<0.075, OR=3.05 [95% CI: 0.86–10.84]) and ongoing pregnancy rate (21.6% versus 8.1%, respectively, p<0.102, OR=3.13 [95% CI: 0.76–12.88]). The metabolomic profile of women in group 1 was characterized by increased levels of isoleucine, valine, leucine, alpha-aminobutyric acid, histidine, threonine, and proline, along with decreased levels of ceramides Cer (d18:0/24:1), Cer (d18:0/16:0), Cer (d18:0/22:0), Cer (d18:1/23:0), Cer (d18:1/25:0), Cer (d18:2/23:0), and Cer (d18:0/24:0).

Conclusion: Adjuvant therapy with MI before gonadotropic stimulation in patients with a poor ovarian response influences lipid and ceramide metabolism in the follicular microenvironment. This therapy also results in a greater number of mature oocytes and high-quality blastocysts, which positively affects the clinical outcomes of IVF infertility treatment.
