ABSTRACT
OBJECTIVE: This study aimed to examine the effect of vitrification on apoptosis and survival in human preantral follicles after thawing.METHODS: This experimental study was conducted at an acute tertiary care hospital from March 2012 to April 2013. Ovaries were sliced into 5×5×1-mm pieces and divided into the following three groups: preantral follicle isolation, ovarian tissue vitrification-warming followed by follicle isolation, and immunohistochemistry of fresh ovarian tissue. For statistical analyses, the Student t-test, chi-square test, Kruskal-Wallis test, and Kaplan-Meier survival analysis were used.RESULTS: A total of 161 preantral follicles (70% secondary) were collected from ovarian cortex tissue of six women between 30 and 37 years of age who underwent oophorectomy due to cervical cancer or breast cancer. There were no significant differences in the follicular morphology of fresh preantral follicles and vitrified follicles after thawing. The mean Fas ligand (FasL) mRNA expression level was 0.43±0.20 (relative to β-actin) in fresh preantral follicles versus 0.51±0.20 in vitrified follicles (p=0.22). The mean caspase-3 mRNA expression level in fresh preantral follicles was 0.56±0.49 vs. 0.27±0.21 in vitrified follicles (p=0.233). One vitrified-thawed secondary follicle grew and developed to an antral follicle within 6 days of culture.CONCLUSION: Vitrification did not affect preantral follicle morphology or mRNA expression of the apoptosis markers FasL and caspase-3. Further studies are required to establish whether vitrification affects the outcomes of in vitro culture and the maturation of preantral follicles.

Background: Polycystic ovary syndrome [PCOS] is an endocrinopathic disorder most commonly experienced by women of reproductive age, and it is characterized by a low-grade chronic inflammatory condition. Excessive fat deposit has been long considered as an etiological factor in the pathogenesis of this inflammatory condition. Currently, body mass index [BMI] or percentage of body fat is used as a marker to assess the body fat composition of a person
Objective: To determine whether BMI or body fat percentage [BFP] can be used as a better marker for measuring inflammation related to body fat accumulation in polycystic ovary syndrome patients
Materials and Methods: This study took place at the Center for Reproductive Medicine, Yasmin Clinic, Cipto Mangunkusumo Hospital from January to December 2015. In this cross-sectional study, 32 reproductive age women with PCOS according to the Rotterdam criteria [2003] participated. Women with hyperandrogenism caused by non-classic congenital adrenal hyperplasia, pregnant and lactating women, etc., were excluded. Some variables such as BMI, clinical hyperandrogenism sign, BFP, and inflammatory markers were assessed and statistically analyzed
Results: From a total of 32 subjects of the study, BFP had a significant positive correlation with procalcitonin levels [r=0.35; p=0.048], while BMI did not [r=0.27; p=0.131]
Conclusion: BFP can be used as a better marker for measuring inflammation related to body fat accumulation in PCOS subjects
ABSTRACT
OBJECTIVE: This study aimed to determine the threshold of anti-Müllerian hormone (AMH) as predictor of follicular growth failure in polycystic ovary syndrome (PCOS) patients treated with clomiphene citrate (CC). METHODS: Fifty female subjects with PCOS were recruited and divided into two groups based on successful and unsuccessful follicular growth. Related variables such as age, infertility duration, cigarette smoking, use of Moslem hijab, sunlight exposure, fiber intake, body mass index, waist circumference, AMH level, 25-hydroxy vitamin D level, and growth of dominant follicles were obtained, assessed, and statistically analyzed. RESULTS: The AMH levels of patients with successful follicular growth were significantly lower (p=0.001) than those with unsuccessful follicular growth (6.10±3.52 vs. 10.43±4.78 ng/mL). A higher volume of fiber intake was also observed in the successful follicular growth group compared to unsuccessful follicular growth group (p=0.001). Our study found the probability of successful follicle growth was a function of AMH level and the amount of fiber intake, expressed as Y=–2.35+(–0.312×AMH level)+(0.464×fiber intake) (area under the curve, 0.88; 95% confidence interval, 0.79–0.98; p<0.001). CONCLUSION: The optimal threshold of AMH level in predicting the failure of follicle growth in patients with PCOS treated with CC was 8.58 ng/mL.
