This study recruited 79 couples undergoing assisted reproductive technology (ART) and measured systemic oxidative stress markers in both partners using oxidative DNA damage (8-OHdG) and lipid peroxidation (8-EPI), along with recorded clinical background and ART outcomes. The authors found that both oxidative stress markers reflected clinical conditions, with prominent negative associations attributable to genital tract infections, endometriosis, uterine myoma, and smoking, and that oxidative stress levels also varied with the partner’s health status. The highest 8-EPI levels occurred in both women and men when biochemical pregnancies did not progress to clinically detectable pregnancies, indicating worse pregnancy maintenance. This paper does not explicitly discuss adenomyosis, but it directly links oxidative stress markers to endometriosis in the ART population studied, relating to endometriosis through the reported negative effects of endometriosis on oxidative stress and ART outcomes.

Abstract

Purpose Previous studies have indicated that OxS (oxidative stress) may appear as a possible reason for poor ART outcome. Our aim was to study OxS levels in both partners of couples seeking Assisted reproduction Technology (ART).

Methods

Altogether 79 couples were recruited. Oxidative DNA damage (8-OHdG) and lipid peroxidation (8-EPI) were measured, and clinical background and ART outcomes were recorded.

Results

Both OxS markers accurately reflected clincal conditions with prominent negative effects attributable to genital tract infections, endometriosis, uterine myoma and smoking. Furthermore, the level of OxS was also affected by partner’s state of health. The highest 8-EPI levels were detected in both partners when biochemically detectable pregnancies did not develop into clinically detectable pregnancies (in women, 97,8 ± 16,7 vs 72.9 ± 22,9, p = 0.007; in men, 89.6 ± 20,4 vs 72,1 ± 22,6, p = 0.049).

Conclusions

To conclude, high grade systemix OxS in both partners may negatively affect the maintenance and outcome of pregnancy. Applying the detection of OxS in ART patients may select patients with higher success rate and/or those who require antioxidant therapy. This would lead to improvement of ART outcome as well as natural fertility. Similar content being viewed by others
