Assessment of Oxidative Stress Changes in Serum and Follicular Fluid in Relevance to GnRH rival Protocol in Iraqi Infertile Ladies Undergoing ICSI

Background: Literary works about the role of rival convention in relationship with oxidative pressure are opposing and there is no reasonable agreement in distributed ripeness articles about the role of opponent reproduction convention with this respect. In reality, a few creators support the presence of expanded oxidative initiated oocyte harm in ladies experiencing ART's; regardless, others have denied such a perception. Hence, the present investigation was arranged so as to think about the conceivable oxidative or hostile to oxidative potential controlled by foe convention. Aim of the study: The aim of the current study was to evaluate the serum and follicular ROS concentration in women undergoing ICSI contrasted between two groups, one receiving conventional antagonist protocol and the other receiving conventional agonist protocol. Patients and Methods: The current case control study included two groups of subfertile women. The study group included 57 women receiving antagonist protocol, whereas, the control group included 10 subfertile women receiving agonist protocol. The study was carried out at High Institute of Infertility Diagnosis and Assisted Reproductive Technologies at Al- Nahrain University. The study started on April 2018 and extended to March 2019. Women in both groups were subjected to ICSI procedure according to procedures and techniques adopted in High Institute of Infertility Diagnosis and Assisted Reproductive Technologies at Al- Nahrain University with a single basic difference concerning the ovarian stimulation protocol. Results: Overall clinical pregnancy rate was 44.7 % being significantly higher in antagonist group in comparison with agonist group 50.9 % versus 10.01 %, respectively (P = 0.019). There was no significant difference in the concentration of ROS at cycle day 2 between antagonist and agonistgroups (P = 0.561). There was highly significant difference in the serum concentration of ROS at day of ova pickup between antagonist and agonist groups (P = 0.009); being less in antagonistgroup and there was highly significant difference in the follicular fluid concentration of ROS between antagonist and agonist groups (P = 0.003); being less in antagonist group. Conclusions: Antagonist protocol is associated with significantly higher positive pregnancy outcome in comparison with agonist protocol because of the anti-oxidant effect attributed to antagonist use.
