BackgroundEndometriosis is a common disease. The most widely used staging system of endometriosis is the revised American Fertility Society classification (r-AFS classification) which has limited predictive ability for pregnancy after surgery. The endometriosis fertility index (EFI) is used to predict fecundity after endometriosis surgery. This diagnostic accuracy study was designed to compare the predictive value of the EFI with that of the r-AFS classification for IVF outcomes in patients with endometriosis.Methods199 women with endometriosis receiving IVF treatment after surgery were analysis. The EFI score and r-AFS classification in their ability to predict these IVF outcomes were compared in the same population. ROC curves were used to analyse the predictive values of the EFI and r-AFS indices for clinical pregnancy, and their accuracies were evaluated by sensitivity, specificity, and the Youden’s index.ResultsThe Area Under the Curve (AUC) of the EFI score (AUC = 0.641, Standard Error(SE) = 0.039, P = 0.001, 95% CI = 0.564-0.717, cut-off score = 6) was significantly larger than that of the r-AFS classification (AUC = 0.445, SE = 0.041, P = 0.184, and 95% CI = 0.364-0.526). The antral follicle count, oestradiol level on day of hCG, number of oocytes retrieved, number of oocytes fertilised, and number of cleaved embryos in the greater than or equal to 6 EFI score group was greater than that of the lower than or equal to 5 EFI score group, and the dose of gonadotropin of the greater than or equal to 6 EFI score group were less than that in the lower than or equal to 5 EFI score group. Implantation rate, clinical pregnancy rate, and cumulative pregnancy rate in the greater than or equal to 6 EFI score group were higher than in the lower than or equal to 5 EFI score group.ConclusionsIt suggests that the EFI has more predictive power for IVF outcomes in endometriosis patients than the r-AFS classification. The clinical pregnancy rate was higher in patients with EFI greater than or equal to 6 score than with EFI lower than or equal to 5 score.

BackgroundMost of infertile women with normal follicle stimulating hormone (FSH) levels and antral follicle count (AFC) at day 2–3 of the period, but poor IVF outcomes may occur when use of routine controlled ovarian stimulation. This paper is to evaluate the predictive value of age-specific FSH levels for IVF-ET outcomes in women with normal ovarian function.MethodsA total of 1287 women undergoing their first IVF cycles were enrolled in this retrospective study. The FSH levels and AFC of all of the women were within normal ranges (FSH ≤ 12 IU/L;AFC ≥ 5). The patients were grouped by age (younger: < 33 years, medium-aged:33–37years and older:38–41years), and within each age group, the patients were subdivided by the upper limit of the 95 % confidence interval (CI) for mean FSH levels. Patients with FSH levels equal to or greater than the upper 95 % CI of FSH in each age group were included into a premature ovarian aging (POA) subgroup (younger:FSH ≥ 7.84, medium-aged: ≥8.12 and older: FSH ≥ 8.47),the remaining patients in each age group were included into a control subgroup. The outcomes of IVF-ET were compared between the POA subgroup and the control subgroup in each age group.ResultsIn each age group, the total dose of gonadotropin(Gn) in the POA subgroups were significantly higher than those of the corresponding control subgroups. In the younger and medium-aged groups, women in the POA subgroups had significantly lower oocyte yields, frozen embryos, and higher rates of poor ovarian response(POR) than those in the corresponding control subgroups. When controlling for age, BMI and AFC, the multiple logistic regression analysis indicated the following: In each age group, the total dose of Gn was significantly correlated with POA; the oocyte yield was significantly related to POA only in the younger group; and in the whole age groups, the incidence of POR in the POA group was 2.719 times greater than in the control group (OR = 2.719, 95 % CI [1.598–4.625], P < 0.001).ConclusionBasal FSH levels combined with age (age-specific FSH levels) can be used as a more accurate marker for the ovarian response in women with normal ovarian reserves undergoing IVF-ET, particularly in women ≤37 years old.

Background Endometrial hyperplasia (EH) is commonly-seen in the patients with endometrial cancer (EC), we aimed to evaluated the risk factors of EC in patients with EH, to provide evidence to the clinical prevention and treatment of EC. Methods This study was a retrospective study design. EH patients confirmed by pathological examinations and treated with hysterectomy in our hospital from June 1, 2018 to February 28, 2021 were included. The clinical characteristics of EC and no-EC patients were compared and analyzed. Logistics regression analyses were conducted to evaluate the risk factors of EC in patients with EH. Results A total of 228 EH patients were included, the incidence of EC in the EH patients was 31.58%. There were significant differences in the age, BMI, diabetes, hypertension and pathology of EH between EC and no EC groups (all P < 0.05), no significant differences in the hyperlipidemia, preoperative CA125, number of deliveries, menopause and endometrial thickness between EC and no EC groups were found (all P > 0.05). Logistic regression analyses indicated that age > 50 y (OR 3.064, 95% CI 1.945–5.931), BMI ≥ 25 kg/m2 (OR 2.705, 95% CI 1.121–3.889), diabetes (OR 3.049, 95% CI 1.781–5.114), hypertension (OR 2.725, 95% CI 1.108–3.431) and severe hyperplasia (OR 3.181, 95% CI 1.496–4.228) were the risk factors of EC in patients with EH (all P < 0.05). Conclusions The risk of EC in EH patients is high, especially for those patients with age > 50 y, BMI ≥ 25 kg/m2, diabetes, hypertension and severe hyperplasia, special attentions should be paid for occurrence of EC and early diagnosis and early treatment are needed for those patients.
