Polycystic ovarian syndrome (PCOS) is a group of clinically distinct endocrine conditions. Insulin resistance-related proteins are involved in PCOS pathogenesis. Irisin is a new myokine that functions similarly to adipokines. Irisin has been linked to insulin resistance and metabolic syndrome. There have been conflicting findings regarding irisin levels and their connection to hormonal and metabolic alterations in PCOS .This study aimed to compare the levels of irisin in follicular fluid and serum between women with PCOS and healthy women and correlate them with oocyte and embryo quality in women undergoing the ICSI cycle .Ninety infertile Iraqi women were enrolled, 46 women with PCOS and 44 weight-matched non-PCOS controls, in whom ICSI was done for them and evaluated the level of follicular fluid, serum Irisin, and insulin level with measure of Homeostasis Model of Assessment-Insulin Resistance (HOMA-IR) and correlate them to with oocyte and embryo quality. HOMA-IR, FF, and serum irisin levels in PCOS considerably increased. (P ≤ 0.01). In addition, there was a significant negative correlation between Irisin levels in follicular fluid and serum with MII oocyte, oocyte maturity rate, and grade 1 embryo. The serum, follicular fluid Irisin, and HOMA-IR were significantly higher in PCOS than in control cases, which may cause a reduction in oocyte maturation, embryo quality, and pregnancy outcome.
Pregnancy-Associated Plasma Protein (PAPP-A) is a zinc metalloproteinase in the insulin growth factor system (IGFs) produced by the syncytiotrophoplast region of the placenta. It plays a critical function in the cleavage of IGFBP4. In the ovary IGFs, it regulates follicular and oocyte maturation, and steroidogenesis. While in polycystic ovarian syndrome (PCOS) Hyperinsulinemia and hyperandrogenemia it causes follicular environment changes and early ovulation resulting in lower oocyte and embryo quality in patients and this will decrease the success of pregnancy in women enrolled in the ICSI cycle. The present study aimed to assess the relationship of PAPP-A levels in serum and follicular fluid in women with PCOS and non-PCOS with oocyte and embryo quality in women undergoing ICSI cycle. 45 infertile Iraqi women were enrolled. Women with PCOS had to meet at least two of the three criteria set by the Rotterdam ESHRE/ASRMS criteria, the age of the included women ranged between 20-45 years. In non-PCOS patients, PAPP-A has higher level in serum and follicular fluid but without a statistically significant difference matching with PCOS group. In addition, there was no significant correlation between PAPP-A levels in serum and follicular fluid with oocytes and embryo characteristics. However, PAPP-A levels are higher in serum and follicular fluid in women with positive pregnancy but without significant differences. PAPP-A had no correlation with oocyte and embryo quality.
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.
Stem cell factor (SCF) is one of the first growth factors derived from granulosa cells in the ovarian follicle plays a critical role in hematopoiesis and the generation of melanocytes and germ cells. SCF also serves an important role in the development of the interstitial cells of Cajal in the intestine and the learning functions in the hippocampal region of the brain. This study aimed to investigate the levels of SCF in follicular fluid (FF) and if it can be used as a potential marker for predicting oocyte, embryo quality, and pregnancy rate. A total of 44 infertile couples involved in the study. All of them underwent controlled ovarian hyperstimulation for the ICSI cycle. Antagonist protocol was used as an ovulation induction protocol. Patients were divided into two groups according to ICSI outcomes as pregnant (23 women) and non-pregnant (21 women) groups. A comparison was done in both groups based on the oocyte, embryo quality, and other ICSI cycle characteristics, and follicular fluid stem cell factor level. SCF level was measured by using an enzyme-linked immunosorbent assay. Our study showed lack of association between patients' characteristics which included (age, BMI, infertility duration, type of infertility, and causes of infertility, basal hormonal, stimulation characteristics levels), FF SCF level and the oocyte characteristics comparison (total number retrieved oocyte, germinal vesicle oocyte (GV), MI oocyte and MII oocytes, and the number of injected oocytes, fertilization rate, and embryo characteristics) between pregnant and non-pregnant groups. The present study showed that Mean follicular fluid SCF was significantly lower in pregnant women in comparison with that of non-pregnant women, 135.92±38.96 pg/ml versus 185.15±63.58 pg/ml, respectively (P=0.003). Raised SCF level in FF harms ICSI outcome.
Background:Defects in reproduction that may involve both the male & female partners result in the inability to procreate which is known as infertility. The use of assisted reproductive technologies (ART’s) has been increasing over the past three decades. Many efforts have been done to compensate for unsatisfac-tory results in in-vitro fertilization (IVF) procedures, so that patients undergo different ovarian stimulation protocols to control retrieval of multiple oocytes in a single cycle. Although ovarian stimulation has an important role in ART’s, it may also have detrimental effects on oocyte quality, embryo quality, and IVF outcomes. Objectives: To assess the effect of long agonist versus antagonist protocols on oocyte and embryo quality in IVF-Intracytoplasmic sperm injection (ICSI). Patients,Materials and Methods: This comparative study was done on the embryos of seventy one infertile fe-males who were undergoing Intracytoplasmic sperm injection (ICSI) treatment regardless to the presence or absence of previous trials. These patients were divided into two groups, 45 of them treated with agonist protocol and other 26 patients treated with antagonist protocol. First oocyte retrieved was used for further assessment. Of the 71 oocytes, there were eight immature oocytes (3 at germinal vesicle (GV) stage, 5 at metaphase I (MI) stage) and three abnormal oocytes, and these were excluded from the following ICSI treatment. Assessment and comparison of oocyte maturity, fertilization rate, cleavage rate and resulting embryo quality were done. Results:The results of the present study showed significant difference (p<0.05) in oocyte number and maturity but no significant (p>0.05) difference between the group treated with long agonist and those on antagonist protocol regarding fertilization rate, cleavage rate, and embryo quality. Conclusions:The type of protocol used in in-vitro fertilization has no detrimen-tal effect on oocyte or embryo quality.
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.
It is well known that oocyte quality is essential in the determination of the developmental potential of the fertilized oocytes. The oocyte developmental potential decreases in all species with increasing age. Use of serum and follicular fluid concentration of GDF9 as biomarkers of oocyte and embryo quality and their relation to pregnancy rate. Eighty-eight women were included in this study are selected from those undergoing intra-cytoplasmic sperm injection. Positive pregnancy was achieved by 14 women. The difference in mean serum and follicular GDF9 between pregnant and non-pregnant women was not significant. MI oocyte count was not significantly correlated to serum and follicular GDF9 (p > 0.05). MII oocyte count showed a non-significant correlation to serum and follicular GDF9 (p > 0.05). Grade 1 embryo count showed a non-significant correlation to serum and follicular GDF9. Grade 2 embryo count showed a non-significant correlation to serum and follicular GDF9. Also, grade 3 embryo count showed a non-significant correlation to serum and follicular GDF9. The current study revealed that serum and follicular GDF9 could not be used as indicators for oocyte maturity, embryo quality, or pregnancy rate.
