Women who have transvaginal oocyte retrieval feel nervous and have mild to moderate pain because a needle is used to poke holes in the vaginal skin and ovarian capsule to get the oocytes. The aim of this study is compare between general and spinal anesthesia effect on ICSI outcome . A cross-sectional study was conducted in the High Institute of Infertility Diagnosis and Assisted Reproductive Technologies/ Al-Nahrain University, from first April 2021 to the first of February 2022. Patients were randomized blindly at time of oocyte retrieval for types of anesthesia given: (50 women subjected to spinal anesthesia and 50 women subjected to general anesthesia). All females were subjected to flexible antagonist protocol. Also, all of them had the same surgical procedure by the same physicians. ICSI outcome was compared between the groups. The study showed there was non-significant difference (p>0.05) between the two groups regarding pregnancy rate with higher oocyte number in women subjected to spinal anesthesia than those who were under the general anesthesia although the difference was not statistically significant. The fertilized oocyte number was non significantly higher in spinal anesthesia group than the general anesthesia. So; spinal anesthesia and general anesthesia have comparable ICSI outcome.
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.
Infertility is described as a couple's failure to conceive for at least a year, using unprotected sex. Even though all anesthetic chemicals have been revealed in the follicular fluids, general anesthesia is still used in many IVF centers for patients who want to get pregnant. This study included 60 infertile women randomly divided into two groups under general anesthesia. 30 patients were given a Ketamine dose of 0.5 mg/Kg and the other 30 patients were received Remifentanil dose of 0.5 µg/Kg for induction of anesthesia. We collected serum for Reactive Oxygen Species (ROS) levels assessment for all patients before and after starting general anesthesia. Routine ICSI procedures was performed on all participants, including clinical evaluation (history, examination, and investigation), controlled ovarian and ovulation stimulation, oocyte retrieval under general anesthesia, follicular fluid collection for postoperative anesthesia medication concentration (Remifentanil and Ketamine), oocyte stripping, oocyte maturity assessment, intra-oocyte sperm injection into mature cells (MII), fertilization and division evaluation and embryo categorization, embryo selection and transfer, luteal phase support, and beta-hCG determination. ROS concentrations were compared between the Remifentanil and Ketamine groups. There was no significant difference in embryo features between Remifentanil and Ketamine, indicating that neither one is superior to the other in this regard. When Remifentanil or Ketamine was taken, there was no significant difference in ROS levels in serum or follicular fluid.
Intratesticular testosterone plays a crucial role in male reproductive function and overall health. Body Mass Index (BMI) and smoking are known lifestyle factors that can influence hormonal balances. Elevated BMI has been associated with alterations in testosterone levels, impacting male fertility and endocrine function. The aim was to examine the concurrent relationships between intratesticular testosterone, BMI, and smoking habits. Biopsies of the testicles were taken from 32 patients with non-obstructive azoospermia. Testicular sperm extraction (TESE) under spinal or general anesthesia was performed after a comprehensive history, physical examination, and investigations. After performing a minced biopsy and centrifuging the fluid, testicular fluid was extracted. The highest intratesticular testosterone levels were in normal patients and lowest levels in over weight patient; on the contrary the highest serum 17-hydroxyprogesterone levels were found in over weight patient and lowest levels in normal weight patients; There were insignificantly higher both intratesticular testosterone and 17-hydroxyprogesterone levels in non-smokers. In conclusion, the statistical analysis revealed that there is an insignificantly low correlation between intratesticular testosterone levels, BMI, and smoking.
Azoospermic patients have the option of undergoing in vitro fertilization procedures, specifically intracytoplasmic sperm injection (ICSI), for which sperm is retrieved from the patient's own testicles and then injected directly into the oocyte. The aim of the study: evaluate the role of repeated sperm extraction by enzymatic and mechanical mincing techniques in azoospemic patients. A total of 32 males with non-obstructive azoospermia participated in the research. Testicular sperm extraction (TESE) was performed under spinal or general anesthesia after a comprehensive history, physical examination, and investigations. After that, the biopsies underwent through a series of mincing processes, both mechanical and enzymatic. Patients gave information including age, body mass index and previous biopsy attempts. In both enzymatic and mechanical methods there was no significant higher sperm recovery in patients with history of previous testicular biopsies (66.7% vs. 38.5%; p=0.209) and (66.7% vs. 30.8%; p=0.102) respectively. Patients who had undergone prior testicular biopsies had marginally higher sperm recovery rates using both enzymatic and mechanical techniques
