Oxidative stress (OS) is a situation that occurs as a result of un-equilibrium between reactive oxygen species (ROS) formation and the antioxidant defence system. 8-hydroxy-2-deoxyguanosine (8-OHdG), an oxidized form of deoxyguanosine, is found in higher levels in aging oocytes. In this cross-sectional study, we aimed to evaluate the effect of 8-OHdG on the intracytoplasmic sperm injection (ICSI). Follicular fluid (FF) samples were taken after removing the oocyte for later analysis of 8-OHdG. The couples participants were categorized according to the cause of subfertility into three groups (female factor, malefactor, and unexplained infertility). Further division according to pregnancy state was done to evaluate the precise role of 8-OHdG on pregnancy state and ICSI outcome. Result : This study showed that the 8-OHdG levels significantly higher in non-pregnant women (p < 0.05). Correlation study showed that 8-OHdG level in follicular fluid is negatively correlating with the number of retrieved oocytes, metaphase two oocytes (MII), fertilized oocytes (2PN = two pronuclei), cleaved zygotes, good quality embryos, and the difference was statistically significant (p < 0.05). Conclusion: The study revealed that the 8-OHdG level in follicular fluid negatively influences ICSI outcome and it is higher in non-pregnant women.
A randomized prospective surgical case series study Setting: antenatal and labor wards and operative theater at AL-Zahra maternity and pediatric teaching hospital at Al-Najaf city, Iraq (tertiary referral center). Participants: patients admitted through the reception room or outpatient clinic, 198 multiparous women in the third trimester ≥30 wk., all patients had a history of prior cesarean section and all cases with a diagnosis of placenta accreta by Doppler ultrasound and at the surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
