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).
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.
Both OxS markers accurately reflected clinical 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).
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.
先前的研究表明,氧化应激(OxS)可能是辅助生殖技术(ART)结局不佳的一个潜在原因。我们的目的是研究寻求ART的夫妇双方的氧化应激水平。
共招募了79对夫妇。检测了氧化DNA损伤(8-OHdG)和脂质过氧化(8-EPI),并记录了临床背景和ART结局。
两种氧化应激标志物均准确反映了临床状况,其中生殖道感染、子宫内膜异位症、子宫肌瘤和吸烟具有显著负面影响。此外,氧化应激水平还受伴侣健康状况的影响。当生化检测到的妊娠未发展为临床可检测到的妊娠时,夫妇双方的8-EPI水平最高(女性:97.8±16.7 vs 72.9±22.9,p = 0.007;男性:89.6±20.4 vs 72.1±22.6,p = 0.049)。
总之,夫妇双方的高度全身性氧化应激可能会对妊娠的维持和结局产生负面影响。在ART患者中检测氧化应激可以筛选出成功率较高和/或需要抗氧化治疗的患者。这将改善ART结局以及自然生育能力。
