Favorable factors included: triple positive breast cancer [positive hormone receptors and positive human epidermal growth factor receptor 2],which is more hormosensitive and chemosensitive; absence of metastasis; correct endometrium preparation; and the patient's optimistic attitude and strict health habits. In contrast, the factors against success were: breast cancer; adjuvant breast cancer therapy gonadotoxicity; the age of the patient(> 40-year-old);endometriosis; ovarian cyst; hydrosalpinx; submucosal fibroids and the respective associated surgery done for the above-mentioned pathology(all resolved prior to the embryo transfer); and a low quantity of ovules(low ovarian reserve) after ovarian stimulation. This is a very special clinical case of a patient with theoretically low pregnancy success probability due to the consecutive accumulation of gynecological and oncological pathologies, who nonetheless became pregnant and delivered a full-term infant and was able to provide adequate breastfeeding.展开更多

In vitro fertilization and embryo transfer （IVF-ET） is a good treatment to infertility. This study aimed to provide external validation of EFI, assess the factors affecting the ability of EFI to predict cumulative spontaneous pregnancy rates （PRs）, and propose reasonable advice for treatment by evaluating the effect of infertility management combining surgery and IVF-ET. Methods： This retrospective study enrolled 345 endometriosis-related infertile women after laparoscopic surgery from January 2012 to January 2016. Among them, 234 patients tried to conceive naturally and were divided into six groups according to their different EFI scores. Of the 345 patients, 307 with an EFI score 〉5 were divided into non-IVF-ET group （n = 209） and IVE-ET group （n = 98） to compare the cumulative PRs. Cumulative PRs＇ curves were calculated using the Kaplan-Meier product limit estimate and the differences were evaluated by log-rank test. Independent predictive factors for pregnancy were assessed using the Cox regression model. Results： Significant differences in spontaneous PRs among different EFI scores were identified （χ2 = 29.945, P 〈 0.05）. The least function score was proved to be the most important factor for EFI （χ2 = 6.931, P 〈 0.05） staging system. In patients with an EFI score ≥5 after 12 months from surgery, the cumulative PRs of those who received both surgery and IVF-ET were much higher than the spontaneous PRs of those who received surgery alone （χ2 =4.160, P = 0.041）. Conclusions： The EFI is a reliable staging system to predict the spontaneous PR of patients. The least function score was the most influential factor to predict the spontaneous PR. Patients with an EFI score ≥5 after 12 months from surgery are recommended to receive IVF-ET to achieve a higher PR.展开更多

But the IVF result of endometriosis patients is still under debate. We investigated the effect of endometriosis on IVF by analyzing the data from a single reproductive center. Methods A retrospective, database-searched cohort study was performed. Relevant information was collected from the electronic records of women who underwent IVF/intracytoplasmic sperm injection between January 2006 and December 2010 in the Assisted Reproductive Unit of Sir Run Run Shaw Hospital. Patients with endometriosis were enrolled the study group. The rest of the women formed the control group. The main outcome was the clinical pregnancy rate. Secondary outcomes were oocytes retrieved number, fertilization rate, high-quality embryo rate, number of high-quality embryo for embryo transplantation, and implantation embryo/high-quality embryo ratio （IE/HQE ratio）. Comparisons were performed by the z2-test and independent t-test. Results The endometriosis group （n=177） had a markedly lower oocytes retrieved number, fertilization rate, implantation rate, and clinical pregnancy rate （7.6_＋5.1, 63.6%, 27.7%, and 45.2%, respectively） compared with the non-endometriosis group （n=4267; 11.8＋7.3, 68.4%, 36.2%, and 55.2%, respectively）. Stratified analysis showed that this difference was found in the subgroup younger than 35-years old, while only fertilization rate and implantation rate were different in the elder subgroup. The ratio of high-quality embryos transferred is lower in endometriosis group （53.7% vs. 71.8%, P 〈0.05）, but there is no difference in IE/HQE ratio between two groups. There is no significant difference in fertilization rate, implantation rate, and clinical pregnancy rate between mild and severe endometriosis patients. Conclusions Endometriosis patients suffer a decreasing IVF pregnancy rates mainly caused by reducing oocytes number and fertilization rate, regardless of the severity of the disease. Appropriate intracytoplasmic sperm injection manipulation might improve the outcomes of IVF.展开更多
