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.

Iron status may influence the outcome of infertile women under the intracytoplasmic sperm injection (ICSI) technique of in vitro fertilization (IVF). The aim of this study is to evaluate iron status and ceruloplasmin ferroxidase activity in the follicular fluid (FF) and their association with IVF outcomes. The study enrolled fertile women with male cause infertility (n=25), infertile women with polycystic ovary syndrome (PCOS; n=21), infertile women with low AMH level (n=26), and women with unexplained infertility (UI; n=27), all undergoing IVF/ICSI. On the day of oocyte suction, the selection of FF samples was accomplished. Iron, ferritin, and transferrin levels, as well as ceruloplasmin (CP) ferroxidase activity, were measured in the FF. In the PCOS group, iron showed significantly higher level (P<0.05) as compared to the control and UI groups. In the PCOS group, ferritin showed significantly higher level (P<0.05) compared with the control group. In the PCOS group, transferrin showed significantly higher level (P<0.05) when compared with the UI group. Also, Cp. ferroxidase activity in the PCOS group showed a lower level, but non-significant difference, compared with the other groups. In conclusion, the increased iron level in the follicular fluid of women with PCOS may lead to decrease pregnancy success after applying IVF protocol.

ABSTRACT Background Determination of oocyte and embryo quality are one of the most important goals in in vitro fertilization (IVF). Antimullerian hormone (AMH) is secreted by the ovarian granulosa cells into blood flow and follicular fluid. Follicular fluid (FF) AMH level is probably a marker of activity of granulosa cells. Objective To evaluate whether high level of FF AMH level is related to success of fertilization and better embryo quality. Materials and methods Sixty-two women, whose FF sample was obtained from a single follicle in each patient, underwent IVF with GnRH-agonist long protocol. Based on oocyte fertilization, the patients were divided into fertilized group (n = 42) and nonfertilized group (n = 20). FF AMH levels were measured in both groups and the quality of embryos was determined in fertilized group. Results Median of FF AMH level in fertilized group was higher than that in nonfertilized group (5.7 vs 2.7 ng/ml) and a statistically significant difference was observed between the two groups. There was a significant difference between FF AMH level and scores of embryos (p < 0.001). The medians levels of FF AMH were 6.7 ng/ml in good quality embryos and 3.80 ng/ml in fair quality embryos. Conclusion Our results indicate that FF AMH level has positive correlation with fertilization and embryo quality; therefore, it can be considered as a marker of IVF outcome.

Background: Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder in reproductive-aged women, which affects 5 to 20% of women in the reproductive age worldwide. This study aimed to compare the levels of SCF in serum and follicular fluid of PCOS patients with those of non-PCOS group and to investigate the relationship of SCF levels with ICSI success.Methods: This is an observational case control study that included the patients who underwent ICSI in the Infertility-IVF center at Ankara University Faculty of Medicine and in a private IVF center between March 2016 and February 2017. The study group consisted of 57 PCOS patients diagnosed according to the Rotterdam criteria and the control group consisted of 75 patients with normofollicular and regular menstrual cycles. Serum and follicular fluid samples were taken on day of oocyte retrieval. Serum and follicular fluid SCF levels were determined by ELISA using the SCF ELISA kit..Results: Serum and follicular fluid SCF levels in PCOS patients were found to be lower than in non-PCOS group. sSCF and ffSCF were statistically significantly higher who had clinical pregnancy than those who had no clinical pregnancy in the PCOS group.Conclusions: SCF levels are low in serum and follicular fluid in patients with PCOS and that the increase in SCF levels is associated with an increase in oocyte maturation and clinical pregnancy rates in PCOS.

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.

Abstract Background Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder with various manifestations and complex etiology. Follicular fluid (FF) serves as the complex microenvironment for follicular development. However, the correlation between the concentration of steroid in FF and the pathogenesis of PCOS is still unclear. Methods Twenty steroid levels in FF from ten patients with PCOS and ten women with male-factor infertility undergoing in vitro fertilization were tested by liquid chromatography-tandem mass spectrometry (LC-MS/MS) in order to explore their possibly correlation with PCOS. Meanwhile, the mRNA levels of core enzymes in steroid synthesis pathway from exosomes of FF were also detected by qPCR. Results The estriol (p < 0.01), estradiol (p < 0.05) and prenenolone (p < 0.01) levels in FF of PCOS group were significantly increased, compared to the normal group, and the progesterone levels (p < 0.05) were decreased in PCOS group. Increased mRNA levels of CYP11A, CYP19A and HSD17B2 of exosomes were accompanied by the hormonal changes in FF. Correlation analysis showed that mRNA levels of CYP11A and HSD17B2 were negatively correlated with percent of top-quality embryos and rate of embryos develop to blastocyst. Conclusion Our results suggest that increased levels of estrogen and pregnenolone in follicular fluid may affect follicle development in PCOS patients, and the mechanism is partially related to HSD17B1, CYP19A1 and CYP11A1 expression change in FF exosomes.

Unrestrained mice were centrifuged for varying periods ranging from 0.5 to 10 hr at 2.5, 5, and 10 x gravity. Liver glycogen and blood glucose levels increased significantly depending on the g load and exposure time. Adrenalectomy completely abolished the glycogen deposition response. The glycogen response was a critical function of the age of mice; unweaned mice did not respond. Blood corticosterone increased significantly prior to the deposition of glycogen. Centrifuged fed mice deposited three times the amount of glycogen of fasted mice. There was no significant difference in the amount of glycogen deposited in centrifuged mice previously starved for 1, 2, or 3 days. It is concluded that the increased glycogen deposited following centrifugation is effected by an increased elaboration of adrenal corticosterone.

Recent studies have suggested a relationship between bovine follicular fluid testosterone concentration and the likelihood of the oocyte being fertilised by an X- or Y-bearing spermatozoon; however, this theory has been challenged. To further test this hypothesis, follicles were dissected from the ovaries of slaughtered heifers, measured and carefully ruptured. The cumulus–oocyte complex (COC) was removed and the follicular fluid collected and testosterone concentration determined by radioimmunoassay. COCs were matured, fertilised and cultured in an individually identifiable manner; all cleaved embryos (2- to 4-cell stage, n = 164) had their sex determined by PCR. Testosterone concentrations were positively skewed. There was no significant difference between follicular fluid testosterone concentrations in male and female embryos (mean ± s.e.m. 51.5 ± 5.59 and 49.5 ± 7.42 ng mL–1, respectively). Linear, quadratic and cubic logistical regression showed that follicular testosterone concentration could not reliably predict the sex of the embryo with odds ratios of 1.001, 1.013 and 1.066, repectively, and coefficient of determination (R2) values of 0.0003, 0.0126 and 0.0567, respectively. Follicular size and testosterone concentration were not related (R2 = 0.087). Finally, follicular size had no influence on embryo sex determination (P = 0.70). In conclusion, under the conditions of the present study, the likelihood of an oocyte being fertilised by an X- or Y-bearing spermatozoon was not affected by the size of the follicle from which it was derived, nor by the testosterone concentration in the follicular fluid.

To investigate the relationship of MUC1, MUC5AC, and the syndrome of spleen and stomach, 109 subjects (34 peptic ulcer (PU), 62 chronic gastritis (CG), and 13 healthy volunteers (CON)) were included. All the subjects included were surveyed with questionnaire to classify them into damp-heat syndrome of spleen and stomach (DHSS), spleen-qi deficiency syndrome (SQD), and CON, examined by gastric endoscope, and biopsied. Rapid urease and methylene blue staining (MBS) were performed on every subject to diagnose for Helicobacter pylori (Hp) infection, and both were defined as Hp-positive. Hematoxylin and eosin (HE) staining was performed on every specimen to explore the histomorphology, inflammatory degree, and inflammatory activity of different groups; then Elivision™ plus kit was used to test the expression of MUC1 and MUC5AC. All the results of digital images were reviewed by two experts blindly. The inflammatory degree with Hp infection was higher than those uninfected or CON, but no significant difference was found between DHSS and SQD. And the expressions of MUC5AC with positive Hp was higher than those with negative Hp or CON regardless of the deficiency and solid syndrome of spleen-stomach but not for MUC1. We speculate that the deficiency and solid syndrome of spleen-stomach is a condition like Tai Ji symbol of dynamic equilibrium, showing the higher expression of MUC5AC but no change of MUC1 in the circumstance of Hp infection.
