During the process of embryo development, endometrial receptivity is very important for the successful implantation of blastocysts. This research investigated the influence of endometrial thickness on the day of oocyte retrieval and fresh embryo transfer on pregnancy outcomes in Iraqi women who are undergoing intracytoplasmic sperm injection (ICSI). Women from Iraq are taking part in this investigation. Participating in in vitro fertilization (IVF) cycles with the use of ICSI was a group of 44 women who were diagnosed with polycystic ovarian syndrome (PCOS) and had unexplained infertility. During the phases of oocyte retrieval and embryo transfer, there were significant differences seen between the two groups (p-values of 0.003 and 0.049), respectively. There was a total of 44 individuals, and 31 of them had negative pregnancy test results. The remaining 13 persons had positive findings. These results illustrate the importance of endometrial thickness in influencing the effectiveness of assisted reproductive technologies in achieving pregnancies.
Reactive oxygen species (ROS) are active chemical compounds created by the body's metabolic process and are crucial in human reproduction. Excessive ROS can contribute to oxidative stress, which has been linked to poor fertility. Embryo culture medium plays an essential role in IVF/ICSI cycles. Eighty participants underwent ovarian stimulation and ICSI cycles; ROS levels were measured in blood samples on the ovum pickup (OPU) day and in each embryo culture dish on ET day using enzyme-linked immunosorbent assay (ELISA). These values were associated with the quality of generated embryos. Women were divided into two groups; the first had day three embryo transfers, whereas the second received blastocyst transfers on day 5. Grades I embryo count was shown to be inversely related to the serum and culture medium ROS levels. Pregnant women had significantly greater levels of GI embryos (p=0.011) and lower levels of GIII embryos (p=0.024). Pregnancy rates for the third-and fifth days of the embryo transfers were 24% and 50%, respectively, with (p=0.045). Pregnancy success rates were increased after ET day five and were strongly influenced by transfer day. Blastocyst-stage embryos with high serum ROS levels were found to be underdeveloped. Culture medium ROS levels can be used as an adjuvant criterion for embryo selection and metabolic marker for developing embryos.
Reactive oxygen species (ROS) are believed to play an important role in the function of the male and female reproductive system, as well as in embryonic development. If the balance between production and elimination of ROS is disturbed, pathogenic consequences would happen. Reactive oxygen species can sometimes exert damaging effects when overabundant, oxidative stress is hypothesized to have a negative impact on, for example, folliculogenesis, embryo development, oocyte maturation, oocyte fertilization, endometriosis, polycystic ovary syndrome and unexplained infertility .8-Hydroxy2-desoxy guanosine (8‐OHdG) is a sensitive indicator of DNA damage as a result of oxidative stress. The study aim was to evaluate follicular fluid levels of 8-Hydroxy2-desoxy guanosine in patients undergoing Intracytoplasmic Sperm Injection (ICSI) and compared the results between both pregnant and non-pregnant patients . One hundred and twenty-seven women included in this study, they underwent controlled ovarian hyper stimulation, program followed by ova pick up, at that time follicular fluid were obtained and freezes till the time of analysis for reactive oxygen species (ROS), patient injected oocyte was cultured in CO2 incubator, then embryo grading, embryo transfer, pregnancy rate and reactive oxygen species level were determined. Follicular fluid 8-OHdG was significantly lower in pregnant females (p < 0.001), 8-OHdG had negative correlations with grade 1 and grade 2 embryos and negative correlation with total blastocyst count. Follicular fluid levels of 8-OHdG provides sensitive tool to predict positive pregnancy outcome in women undergoing ICSI.
Various types of anesthetic techniques were described for oocyte recovery. Different anesthetic agents have been used with different effects on oocyte quality and embryonic development and studies on the potential toxicity of general anesthesia ended up with conflicting results. Many experiments as well as human studies documented the existence of anesthetic agents in the follicular fluid (FF) with possible adverse effects on the oocyte quality and subsequent embryo development. Ketamine and remifentanil were used for the studied groups to compare oocytes and embryos characteristic of infertile women during oocytes retrieval under general anesthesia: one group receiving ketamine, midazolam, and propofol and the other group receiving remifentanil, midazolam and propofol. 60 infertile females were undergoing intracytoplasmic sperm injection categorized in two groups, group I received midazolam, remifentanil and propofol; whereas, group II received midazolam, ketamine and propofol. There was highly significant difference in mean abnormal oocyte between ketamine and remifentanil groups. Grade III embryos were significantly limited to ketamine group. FF ketamine and remifentanil were not significantly correlated to any of oocyte characteristics or embryo characteristics. Anesthetic agents, ketamine and remifentanil, were detected in the FF of infertile women and within recommended doses. Ketamine resulted in adverse effects on oocyte and embryo quality in comparison with remifentanil represented by greater percentage of abnormal oocytes and that bad quality embryos were limited to ketamine group.
The estimation of oocyte quality in human in vitro fertilization (IVF) is an important point for the embryologists. Oocyte selection and the identification of the best oocytes may help to limit an overproduction of embryos and to improve the results of oocyte cryopreservation programs. The follicular fluid (FF) can be provided easily during oocyte pick-up and known to represents an optimal source for non-invasive biochemical predictors of oocyte quality. However, till now no substance was found to be used as reliable markers of oocyte competence to fertilization, embryo development and pregnancy. Metabolism and ATP levels within the oocyte and adjacent cumulus cells are associated with quality of oocyte and optimal development of a healthy embryo. Lipid metabolism provides a potent source of energy and its importance during oocyte maturation is being increasingly recognised. Objectives: To determine the effect of lipids (Cholesterol. Triglyceride and HDL) level in serum and follicular fluid in predicting oocyte quality, embryo quality and outcome in patients undergoing intracytoplasmic sperm injection program Patients and Methods: Fifty eight (58) infertile women with an age range 21-41 years old undergoing intracytoplasmic sperm injection cycles were included in this study. Lipids (Cholesterol. TG and HDL.,) levels in serum and follicular fluid were measured by auto analyzer for biochemistry (Flexor El_200) and correlation with oocyte quality, embryo quality and ICSI outcome was done. Results: The results of this study showed no significant (p<0.05) difference in lipid levels in serum and follicular fluid between pregnant and non pregnant females as well as non significant correlation was found between lipid level in serum and follicular fluid in relation to oocyte quality and embryo quality. Conclusions: Serum and follicular fluid lipids are not good predictors of oocyte quality, embryo quality or ICSI outcome in women undergoing IVF/ICSI cycles. Accordingly, these biomarkers would be less reflective of the follicular environment and that the effect of maternal metabolic disorders on oocyte quality and fertility outcome is complex and of a multifactorial kind.
Back ground: Optimal IVF and embryo culture conditions depend on the composition of culture media being the most important determinants of successful in vitro interaction of the gametes and subsequent embryo development. ATP is fundamental factor to maintain the life, by providing energy, and controlling the cell function and metabolism. Objective: To investigate the effect ATP supplied to culture medium on fertilization rate and in mice as model for human being. Materials and Methods: The female mice (90) were superovulated using superovulation program (SOP) to produce large number of oocyte were divided into three groups, G1 inseminated with vassal sperm in vitro alone (control) , G2 inseminated with vassal sperm in vitro using SMART enriched with ATP(1.25mM). While, G3 inseminated with vassal sperm in vitro using SMART medium enriched with ATP (2.5mM). Mouse spermatozoa were collected from both vas deferens. Then sperm parameters were assessed after 30 min. IVF technique was performed for 3 groups. Results: The results of the present study appear, significantly increment (P<0.05) in the IVF (%) was observed when using 2.5 mM ATP as compared to 1.25 mM ATP and control group. Conclusions: The result showed that addition of high ATP concentration (2.5 mM) enriched to the culture medium improved percentage of in vitro fertilization.
