Material and methods This case–control study was conducted on 70 unexplained infertile women who were included in a tertiary university hospital. Both groups of basal FSH, estradiol, antimullerian hormone (AMH), inhibin B, ovarian volume, total antral follicle count (AFC), ovarian volume, and ovarian stromal blood flow (peak systolic velocity (PSV), S/D (systole and diastole ratio), resistance index (RI), and pulsatility index (PI)) values were compared. Results The mean AMH, inhibin B, PSV, and stromal blood flow values of the control group patients were higher than those in the unexplained infertility group. However, the values of the means of RI and PI of the cases in the control group were lower than those in the infertility group. When PI’s value was ≥ 2.00, its sensitivity was 65.7%, and its specificity was 64.3%. In the case of the RI, its value was ≥ 0.745, its sensitivity was 65.7%, and its specificity was 62.9%. In order to show ovarian reserve in unexplained infertile cases, the sensitivity values can be sorted from high to low as follows: PI > RI > estradiol > FSH > ovarian volume > AFC > inhibin B > stromal blood flow > PSV > S/D. Conclusion In the unexplained infertile patient group with normal ovarian reserve test results, basal estradiol, decreased PI, and RI values may be used as good ovarian reserve predictors.","PeriodicalId":18532,"journal":{"name":"Middle East Fertility Society Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136346512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In polycystic ovarian syndrome, the vitamin D endocrine system is regulated by the vitamin D receptor (VDR) associated with type II diabetes, endocrine dysfunctions, and insulin resistance. Therefore, the current paper deals with the investigation of the connection between Cdx2 VDR gene polymorphism and the biochemical factors in obese PCOS women. Material and methods In the current case–control study, 40 obese women without PCOS and 38 obese women with PCOS were enrolled in May–September 2016. Insulin, IGF1, FBS, and HOMA-IR were examined for the participants along with the allelic and genotypic frequency of Cdx2 polymorphism G/A (rs11568820) from Isfahan Fertility and Infertility Center, Iran. The ASM-PCR (multiplex allele-specific PCR) technique was utilized in this regard. Results The age of PCOS women was less ( P < 0.001) than the controls. In PCOS women, insulin, FBS, and HOMA-IR serum levels were higher than in the control women (all P values 0.05). For GG, AG, AA,A, and G Cdx2 (A/G) genotypic/allelic frequencies were 84.2%, 15.8%, 0%, 7.9%, and 92.1% in cases and 87.5%, 12.5%, 0%, 6.3%, and 93.8% in controls, respectively. HOMA-IR ( P = 0.047 and P = 0.033, respectively) and insulin than those with the AG genotype were in PCOS women with the GG Cdx2 genotype. The highest IGF-1 mean value ( P = 0.020) was found for the AG genotype in PCOS. In our study, a significant relation was found only between PCOS and FBS, in terms of a logistic regression analysis of Cdx2 and parameters. Conclusion In the present study, it was indicated that the GG genotype in PCOS subjects was associated with the IGF-1, HOMA-IR, and insulin. Similarly, no association was found between obese PCOS patients and Cdx 2 in the 1a promoter area of the VDR gene in our study.","PeriodicalId":18532,"journal":{"name":"Middle East Fertility Society Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135137401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Termination of pregnancy could be achieved either by surgical evacuation or medical or expectant management. Letrozole is a third-generation aromatase inhibitor. According to many recent studies, letrozole given for three days before the administration of misoprostol was more effective than misoprostol alone at inducing abortion. Our study compared the efficacy of various letrozole regimens (10 mg/d for three days and a single dose of 20 mg) combined with misoprostol vs. misoprostol alone in inducing abortion. To find the most efficient regimen of letrozole administered before misoprostol to induce an abortion. Methodology This prospective, parallel, three-arm, single-blinded, allocation-concealed randomized controlled trial was conducted in Sohag Teaching Hospital in Upper Egypt. We randomly divided 105 patients with anembryonic missed abortion (up to 63 days gestation) with no history of medical disorders or a history of allergies to misoprostol or letrozole into three equal groups (a single-dose letrozole group, a multiple-dose letrozole group, and a misoprostol-only group). The complete abortion rate, incomplete abortion rate, failure to abort rate, and induction-to-abortion interval were all collected. All statistical calculations were performed using the computer program SPSS (Statistical Package for the Social Science, SPSS Inc., Chicago, IL, USA). Results The complete abortion rate was significantly higher in the single-dose letrozole and multiple-dose letrozole groups than in the misoprostol group ( p values = 0.0455 and 0.001, respectively). On the other hand, there was no significant difference in the complete abortion rate between the single-dose group and the multiple-dose letrozole group ( p -value = 0.1713). The time to complete abortion was significantly shorter in the single-dose and multiple-dose letrozole groups than in the misoprostol group ( p values = 0.0036 and 0.0049, respectively). On the other hand, there was no significant difference in the time to complete abortion between the single-dose letrozole group and the multiple-dose letrozole group ( P = 0.532). Conclusion Single- and multiple-dose letrozole regimens followed by misoprostol had a higher rate and a shorter time to complete abortion than misoprostol alone.

Methods This randomized clinical trial was carried out in the department of infertility treatment at Arash Women’s Hospital from May 2019 to May 2021. The eligible women with normal ovarian reserve tests who had endometriosis diagnosis and underwent IVF/ICSI cycles were evaluated. A flexible regimen of GnRH-antagonist protocol was used for COS. In the experimental ( n = 34), the patients received 5 mg letrozole daily for the first 5 days in combination with 150 IU of recombinant follicle-stimulating hormone (rFSH). In the control group ( n = 30), the patients received only the same dose of rFSH. The treatment cycle was compared between groups. Results Analysis of demographic characteristics, severity of endometriosis, and baseline hormonal tests of patients showed that the two groups were similar and comparable. The means of total used gonadotropins ampoules and serum E 2 level on oocyte trigger day in the letrozole group were significantly lower than those of in the control group ( P = 0.03 and P = 0.004, respectively). No statistically significant difference in terms of the total number of retrieved and MII oocytes as well as the total numbers of obtained and top-quality embryos, and cryopreserved embryos was found. Conclusion The co-treatment of letrozole with gonadotropins during the antagonist protocol was associated with a reduction in the total dose of gonadotropins, although it had no effect on the oocyte or embryo yield in patients with endometriosis.

It is an essential hormone to have successful embryo implantation into the endometrium. Objective In the current study, we compared the clinical outcomes of patients with different levels of P4 on embryo transfer day and aimed to determine the optimum threshold for P4 in the luteal phase. Material and methods We performed a prospective cohort study on 100 patients who were referred to the Taleqani Infertility Treatment Institute to undergo frozen embryo transfer (FET). Endometrial preparation was programmed using an estrogen (E2) and progesterone supplement. FET was carried out 3 days after administration of the first dosage of progesterone. We measured serum progesterone levels on embryo transfer day. Clinical pregnancy was the main investigated outcome. We used a parametric receiver operating characteristic curve (ROC) to determine the best-cut points of P4 on embryo transfer day. Results Overall, the average endometrial thickness was 7.9 ± 0.2 mm. We observed no association between endometrial thickness and clinical pregnancy ( P value = 0.719). The mean number of the transferred embryos in all investigated cycles was 1.5 ± 0.5, and 80.0% of the transferred embryos were high quality (high and medium level). The average progesterone level in cycles with clinical pregnancy was 17.2 ± 3.3 ng/mL. It was only 13.4 ± 9.4 in patients without clinical pregnancy. The observed difference was statistically significant ( P value = 0.032). The estimated AUC for the drawn ROC curve was 0.71 indicating a high predictive value. Conclusion The current study demonstrated that high and low serum progesterone (P4) levels on embryo transfer day were associated with reduced clinical outcomes following blastocyst transfer during IVF/ICSI. However, more studies with large sizes are required in this regard.","PeriodicalId":18532,"journal":{"name":"Middle East Fertility Society Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136114564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is to investigate the effect of iodine therapy on the ovarian reserve of women at reproductive ages. Methods In this prospective study, 60 patients with thyroid cancer aged 18 to 35 who were undergoing iodine therapy for the first time in 2018–2019 were included in the study. Patients with underlying diseases and any ovarian disorders and patients who needed repeated iodine treatment were excluded from the study. Anti-Müllerian hormone (AMH) level of patients was evaluated 4 times before, 3, 6, and 12 months after iodine therapy. The significance level of the P -value study was considered less than 0.05. Results The average age of the patients was 29.53 ± 4.53 years. With aging, AMH level decreases significantly. No significant correlation was observed between smoking, menarche age, and abnormal uterine bleeding with AMH level. The average AMH before, 3, 6, and 12 months after iodine therapy was 2.25 ± 0.55 ng/ml, 1.15 ± 0.35 ng/ml, 1.58 ± 0.47 ng/ml, and 1.94 ± 0.58 ng/ml, which has a significant decrease respectively 49.05%, 29.55%, and 13.58% compared to the amount before iodine therapy ( P -value < 0.001).
