RESUMO
OBJECTIVE: Chronic endometritis (CE) is an inflammatory condition with several different risk factors. We aimed to examine whether intrauterine abnormalities, such as endometrial polyps, submucosal myomas, intrauterine adhesions, or a septate uterus, were associated with an increased likelihood of developing chronic endometritis. METHODS: A cross-sectional study was conducted on 335 infertile women who underwent hysteroscopy surgery at the Ayatollah Taleghani Hospital Infertility Center, affiliated by Shahid Beheshti University of Medical Sciences, in 2022. All participants in the study underwent hysteroscopic surgery, which allowed for direct visualization of the intrauterine cavity, and endometrial biopsies were taken for further analysis. To characterize endometritis, plasma cell infiltration was assessed. Patients with ≥5 plasma cells observed in 10 high-power fields were defined as having chronic endometritis. RESULTS: Endometritis was observed in 51.3% of the patients, totaling 172 individuals. Logistic regression analysis revealed that patients with endometrial polyps had 5.2 times higher odds of developing endometritis compared to patients without polyps (95% CI = 2.9, 9.2) (p-value <0.001). Similarly, patients with intrauterine adhesions had a significant increase in the odds of endometritis (OR = 4.6, 95% CI = 2.1, 10.1) (p-value <0.001). CONCLUSIONS: Treatment or removal of endometrial abnormalities through hysteroscopic procedures may help to reduce the risk of chronic endometritis and improve fertility outcomes. Further research is necessary.
RESUMO
BACKGROUND: Various protocols have been approved to improve the response rate leading to successful fertilization in poor ovarian responders (PORs). The application of double ovarian stimulation (DuoStim) in the follicular and luteal phases of the same ovarian cycle has been shown as an intriguing option to achieve more oocyte retrievals in the shortest time. The aim of the current study is to compare the outcomes of different protocols, minimal stimulation (MS) and Duostim. MATERIALS AND METHODS: This randomized clinical trial was performed on 42 in vitro fertilization (IVF) candidates with POR diagnosis. Patients were classified into two equal groups and treated with the DuoStim protocol and MS protocol. The IVF outcomes, including retrieved follicles, oocytes, metaphase II (MII) oocytes and embryos, were compared between these groups. RESULTS: The patients' characteristics including age, anti-mullerian hormone (AMH), follicle stimulating hormone (FSH), luteinizing hormone (LH), and antral follicle count (AFC) were collected and compared. It showed there was no significant difference between the two groups baseline characteristics (P>0.05). We observed that the DuoStim protocol resulted in a significantly higher score in comparison with the MS protocols , including the number of follicles (6.23 ± 2.93 vs. 1.77 ± 1.66, P<0.001), retrieved oocytes (3.86 ± 2.57 vs. 1.68 ± 1.58, P=0.002), MII oocytes (3.36 ± 2.42 vs. 1.27 ± 1.27, P=0.001) and obtained embryos (2.04 ± 1.64 vs. 0.77 ± 0.86, P=0.003). CONCLUSION: The DuoStim protocol is a favourable and time saving plan that is associated with more oocytes in a single stimulation cycle. The DuoStim protocol significantly can result in more frequent MII oocytes and embryos. We figured that the higher number of oocytes and embryos might have led to a higher rate of pregnancy (registration number: IRCT20200804048303N1).
RESUMO
OBJECTIVE: Premature ovary failure (POF) is a severe health condition with multiple negative outcomes, which deteriorate a patient's life. The current study aimed to evaluate the therapeutic effect of mesenchymal stem cells (MSCs) derived from peripheral blood in the treatment of women with the POF background. METHODS: The current study was a pilot study carried-out on women younger than 40 with premature ovarian failure. Study participants underwent 4-months cell therapy using Mesenchymal stem cells extracted from peripheral bloods. Serum level of Follicle-stimulating hormone (FSH), Estradiol (E2), Anti-mullerian hormone (AMH), and Antral follicle count (AFC) were the main investigated outcomes that were assessed at baseline, month two and month four of the very small stem cell intervention. RESULTS: Average serum level of FSH was 45.0 (12.1) mIU/mL at baseline and continually decreased during the study and reached 33.2 (12.4) mIU/mL in the fourth month. The average AMH level was 0.10 ng/mL prior to the intervention and increased to 0.13 ng/mL in the 2nd month and 0.15 ng/mL in the fourth month. The level E2 was 85.7 (23.6) pg/ml on average at baseline, while the average E2 reduced to 77.2 (25.6) pg/ml in the fourth month. Average number of AFC was 2.0 (0.8) at baseline. We observed a gradual increase in the second month (Mean AFC=2.2) and after four months it increased to 3.1 (1.8) as the highest menstrual restoration and pregnancy was observed in 10% of our study participants. CONCLUSIONS: MSCs could significantly improve hormone secretion in women with POF. Implantation of MSCs in women with POF background was associated with an increase in AMH and AFC, while it downed the serum level of E2 and FSH. MSCs could also lead to menstrual restoration and pregnancy in women with POF.
RESUMO
Empty follicle syndrome is a rare condition characterized by failure to retrieve oocytes despite repeated careful aspiration of mature precursor follicles during controlled ovarian stimulation. This report presents a case of empty follicle syndrome in a patient with polycystic ovary syndrome using a gonadotropin-releasing hormone agonist as a trigger for final oocyte maturation. No oocytes were retrieved from the right ovary and the procedure was discontinued. The patient was administered an injection with 10,000 units of HCG and 3 oocytes were obtained after 24 hours. All oocytes were mature (MII); fertilization was performed with sperm from the patient's husband resulting in 3PN zygotes. The formation of 3PN zygotes from ICSI might be due to oocyte cytoplasmic disorders caused by long-term exposure to gonadotropins and increased duration of stimulation. Although our patient had false empty follicle syndrome and the hCG rescue protocol led to the retrieval of oocytes, the oocytes were not of good quality. As previously described, empty follicle syndrome is not a predictor of success in subsequent cycles. Our patient's next cycle was uneventful.
