Induced pluripotent stem cells in reproductive medicine

[摘要] Background: Decreased endometrial recep­ti­vity is suspected to be one of the factors causing in­fertility in women with Polycystic Ovary Syn­dro­me (PCOS). Endometrial abnormalities in PC­OS­ due to impaired balance include estrogen, pro­­­­gesterone, growth factors, cytokines and cell at­tach­­­ment modulators including leptin. This study aims to determine the expression of leptin in the endometrium which is suspected to be more common in PCOS patients and related factors. Subjects and Method: A retrospective-case control study was conducted at Dr. Moe­wardi general hospital, Surakarta. A total of 60 women were involved; 30 infertile women with PCOS based on Rotterdam criteria (if found two of the three symptoms, including hyperandrogenism, ovu­la­tion dysfunction and/or polycystic ovaries from ultrasonography) and 30 normal women as con­trol group. Demographic data such as age, family history of PCOS, menarche, BMI, occupation, and edu­cation were recorded. Leptin expression was acquired from endometrium biopsy with IHC examination on day 19-24 of the menstrual cycle; under the condition that inclusion and exclusion cri­teria are fulfilled. The statistical analysis was per­formed using the Mann-Whitney test. Results: Mean of leptin expression was found significantly higher in PCOS group (Mean= 59.16; SD= 49.34) compared to control group (Mean= 6.00; SD= 22.98, with p= 0.001. PCOS (b= 0.42; 95% CI= 0.10 to 0.73; p= 0.010) and obesity (b= 0.31; 95% CI= 0.41 to 0.58; p= 0.025) increased leptin expression. Conclusion: There is a difference in leptin ex­pres­­sion in the endometrium of PCOS compared to nor­mal.  Leptin expression is higher in the en­do­metrium of women with PCOS and obesity compared to nor­mal.
