Polycystic ovary syndrome (PCOS) is one of the most common hormonal endocrine disorders in women of reproductive age. It consists of a heterogeneous collection of signs and symptoms that together form a disorder spectrum. The diagnosis of PCOS is principally based on clinical and physical findings. The extent of metabolic abnormalities in women with PCOS varies with phenotype, body weight, age, and ethnicity. For general population, the prevalence of hyperandrogenism and oligomenorrhea decreases with age, while complications such as insulin resistance and other metabolic disturbances increase with age. Obese women with PCOS have a higher risk of developing oligomenorrhea, amenorrhea, hyperandrogenemia, insulin resistance, and lower luteinizing hormone (LH) to follicle stimulation hormone (FSH) ratios than non-obese women with PCOS. The LH to FSH ratio is a valuable diagnostic tool in evaluating Taiwanese women with PCOS, especially in the diagnosis of oligomenorrhea. Overweight/obesity is the major determinant of cardiovascular and metabolic disturbances in women of reproductive age.
Objective: To determine the age specific serum anti-M$\ddot{u}$llerian hormone (AMH) reference values in Korean women with regular menstruation. Methods: Between May, 2010 and January, 2011, the serum AMH levels were evaluated in a total of 1,298 women who have regular menstrual cycles aged between 20 and 50 years. Women were classified into 6 categories by age: 20-31 years, 32-34 years, 35-37 years, 38-40 years, 41-43 years, above 43 years. Measurement of serum AMH was measured by commercial enzyme-linked immunoassay. Results: The serum AMH levels correlated negatively with age. The median AMH level of each age group was 4.20 ng/mL, 3.70 ng/mL, 2.60 ng/mL, 1.50 ng/mL, 1.30 ng/mL, and 0.60 ng/mL, respectively. The AMH values in the lower 5th percentile of each age group were 1.19 ng/mL, 0.60 ng/mL, 0.42 ng/mL, 0.27 ng/mL, 0.14 ng/mL, and 0.10 ng/mL, respectively. Conclusion: This study determined reference values of serum AMH in Korean women with regular menstruation. These values can be applied to clinical evaluation and treatment of infertile women.

Menstrual cycle irregularity reflects the reproductive health of women of childbearing age, but studies are scant on women in communities. In this study, we identified factors associated with menstrual cycle irregularity among 884 community women of childbearing age (19-40 years) and confirmed the relationship between menstrual cycle irregularity and depressive symptoms. Data were collected through online or mobile platforms. We noted that 25% of participants had menstrual cycle irregularity. Multivariable ordinal logistic regression analysis revealed that age, irregular eating, and depressive symptoms were associated with menstrual cycle irregularity. After adjusting for confounding variables, participants with depressive symptoms were at a slightly higher risk of menstrual cycle irregularity (odds ratio = 1.078, confidence interval = 1.021-1.139). Additional support be provided for community-living women of childbearing age with depressive symptoms, to improve their reproductive health
Objective: To evaluate the ability of serum anti-M$\ddot{u}$llerian hormone (AMH), FSH, and age to clinically predict ovarian response to controlled ovarian hyperstimulation (COH) in IVF patients with endometriosis. Methods: We evaluated 91 COH cycles, including 43 cycles with endometriosis (group I) and 48 cycles with male factor infertility (group II) from January to December, 2010. Patients were classified into study groups based on their surgical history of endometriosis-group Ia (without surgical history, n=16), group Ib (with a surgical history, n=27). Results: The mean age was not significantly different between group I and group II. However, AMH and FSH were significantly different between group I and group II ($1.9{\pm}1.9$ ng/mL vs. $4.1{\pm}2.9$ ng/mL, $p$ <0.01; $13.1{\pm}7.2$ mIU/mL vs. $8.6{\pm}3.3$ mIU/mL, $p$ <0.01). Furthermore, the number of retrieved oocytes and the number of matured oocytes were significantly lower in group I than in group II. In group II, AMH and FSH as well as age were significant predictors of retrieved oocytes on univariate analysis. Only the serum AMH level was a significant predictor of poor ovarian response in women with endometriosis. Conclusion: Serum AMH may be a better predictor of the ovarian response of COH in patients with endometriosis than basal FSH or age. AMH level can be considered a useful clinical predictor of poor ovarian response in endometriosis patients.

Background: The use of smokeless tobacco (SLT) among women is increasing in India, especially among those with limited education and resources. Preventing the initiation of SLT among women is critical since it has known negative consequences for oral and reproductive health. Most research on tobacco initiation in India focuses on adolescents. This paper addresses the unrecognized issues of post marital initiation among women of reproductive age, highlighting the importance of reproductive stages in women's tobacco initiation. The objective is to examine the correlates of SLT initiation among low income women in Mumbai from pre-marriage through early marriage, first pregnancy and beyond, using case examples to illustrate initiation during each of these stages. Materials and Methods: In 2011-2012, cross-sectional community level survey data were collected from a representative sample of 409 daily SLT-using married women aged 18-40 years in a low income community in Mumbai. Information on socio-demographics, initiation by reproductive stage, types of tobacco use, childhood exposure to tobacco, learning to use, and initiation influences and reasons were collected through a researcher-administered survey. Univariate and bivariate analysis assessed factors influencing initiation of SLT use by reproductive stage. In addition 42 narratives of tobacco use were collected from a purposive sample of pregnant and non-pregnant married women addressing the same questions in detail. Narratives were transcribed, translated, and coded for key concepts including initiation of tobacco use. Results: Thirty-two percent of women initiated SLT use before marriage, 44% initiated after marriage but before pregnancy, 18.1% initiated during their first pregnancy and the remainder started after their first pregnancy. Mean age of marriage among women in this study was 16 years. Younger women (i.e. age at time of the interview of less than 30 years) were 0.47 [95% CI (0.32, 0.87)] percent less likely to initiate after marriage than women aged more than 30 years. Women who got married before 18 years of age were 2.34 [95% CI (1.40, 3.93)] times more likely to initiate after marriage than their counterparts. Childhood exposure was a predictor for initiating SLT use prior to marriage but not after. Women reporting tooth and gum pain were 1.85 times more likely to initiate after marriage than their counterparts. Husband and neighbours were the most significant influences on post-marital initiation. Narratives highlighted differences in processes of initiation pre and post marriage and during pregnancy. Conclusions: Most tobacco prevention interventions are directed to adolescents in school. This study suggests that especially for low literate or illiterate women, school based interventions are ineffective. To be effective strategies to prevent SLT initiation must reach women in urban areas at or immediately after marriage and during their first pregnancy. Messages must negate culturally rooted beliefs about the health benefits of SLT in order to prevent initiation and onset of daily use.

Objective: It is widely accepted that aging decreases women's fertility capacity. The aim of this study was to assess correlations between maternal age and the morphokinetic parameters and cleavage pattern of embryos. Methods: The morphokinetics of embryos derived from women < 30, 30-35, 36-40, and > 40 years of age were compared retrospectively in terms of time of second polar body extrusion, time of pronuclei appearance, time of pronuclei fading, and time of two to eight discrete cells (t2-t8). Furthermore, abnormal cleavage patterns such as uneven blastomeres at the two-cell stage, cell fusion (Fu), and trichotomous mitoses (TM) were assessed. Results: Only t5 occurred later in women aged 36-40 and > 40 years when compared with those aged < 30 and 30-35 years (p< 0.001). Other morphokinetic timing parameters, as well the presence of uneven blastomeres, were comparable between the groups (p> 0.05). However, Fu and TM were more common in women aged > 40 years than in younger women (p< 0.001). Conclusion: Maternal age was correlated with the cleavage pattern of embryos. Therefore, evaluating embryo morphokinetics may contribute to optimal embryo selection, thereby increasing fertility in patients with advanced maternal age.

Objective: The aim of this study was to evaluate the influence of maternal age on fertilization, embryo quality, and clinical pregnancy in patients undergoing intracytoplasmic sperm injection (ICSI) using testicular sperm from partners with azoospermia. Methods: A total of 416 ICSI cycles using testicular spermatozoa from partners with obstructive azoospermia (OA, n = 301) and non-obstructive azoospermia (NOA, n = 115) were analyzed. Female patients were divided into the following age groups: 27 to 31 years, 32 to 36 years, and 37 to 41 years. The rates of fertilization, high-quality embryos, clinical pregnancy, and delivery were compared across maternal age groups between the OA and NOA groups. Results: The rates of fertilization and high-quality embryos were not significantly different among the maternal age groups. Similarly, the clinical pregnancy and delivery rates were not significantly different. The fertilization rate was significantly higher in the OA group than in the NOA group (p< 0.05). Age-group analysis revealed that the fertilization and high-quality embryo rates were significantly different between the OA and NOA groups in patients aged 27 to 31 years old, but not for the other age groups. Although the clinical pregnancy and delivery rates differed between the OA and NOA groups across all age groups, significant differences were not observed. Conclusion: In couples using testicular sperm from male partners with azoospermia, pregnancy and delivery outcomes were not affected by maternal age. However, women older than 37 years using testicular sperm from partners with azoospermia should be advised of the increased incidence of pregnancy failure.
Objective: The aim of this study was to evaluate pregnancy outcomes and the live birth rate at 1-year age increments in women aged ${\geq}40years$ undergoing fresh non-donor in vitro fertilization (IVF) and embryo transfer (ET), and to identify predictors of success in these patients. Methods: This retrospective study was performed among women ${\geq}40years$ of age between 2004 and 2011. Of the 2,362 cycles that were conducted, ET was performed in 1,532 (73.1%). Results: The clinical pregnancy rate and live birth rate in women ${\geq}40years$ significantly decreased with each year of increased age (p<0.001). Maternal age (odds ratio [OR], 0.644; 95% confidence interval [CI], 0.540-0.769; p<0.001), basal follicle-stimulating hormone (FSH) levels (OR, 0.950; 95% CI, 0.903-0.999; p=0.047), the number of high-quality embryos (OR, 1.258; 95% CI, 1.005-1.575; p=0.045), and the number of transferred embryos (OR, 1.291; 95% CI, 1.064-1.566; p=0.009) were significant predictors of live birth. A statistically significant increase in live birth rates was seen when ${\geq}3$ embryos were transferred in patients 40 to 41 years of age, whereas poor pregnancy outcomes were seen in patients ${\geq}43years$ of age, regardless of the number of transferred embryos. Moreover, the cumulative live birth rate increased in patients 40 to 42 years of age with repeated IVF cycles, but the follicle-stimulating hormone in those ${\geq}43years$ of age rarely showed an increase. Conclusion: IVF-ET has acceptable outcomes in those < 43 years of age when a patient's own oocytes are used. Maternal age, basal FSH levels, and the number of high-quality embryos and transferred embryos are useful predictors of live birth.
Objectives : The reproductive history of women has been suggested to have a possible influence on the risk of osteoporotic fractures. The purpose of this study was to assess the association between reproductive history and hip fractures in the elderly women. Methods : The study subjects were drawn from women members of the Korean Elderly Pharmacoepidemiologic Cohort (KEPEC), aged 65 years or over, whose reproductive histories were available, and who were beneficiaries of the Korea Medical Insurance Corporation (KMIC) in 1993 and lived in Busan city, Korea. The information on reproductive histories, and possible confounders, were collected from mailed questionnaires. Potential hip fracture cases were collected from the claims data obtained between 1993 and 1998, with a hospital survey conducted to confirm the final diagnoses. Rate ratios and their 95% confidence intervals, were calculated using a Cox's proportional hazard model. Results : Following up 5,215 women for 6 years, 51 cases were confirmed with hip fractures. When adjusted for age, weight and physical activity, the rate ratio of hip fractures in women who had given birth three or more times was 0.56 (95% CI: 0.25-1.25), compared with those who had given birth two or less times. When adjusted for age, number of births, weight and physical activity, the rate ratio in women who first gave birth when younger than 22 years was 0.60 (95% CI: 0.34-1.08) compared with those who had giving birth at 22 years or older. Conclusions : According to these findings, an early age when first giving birth might decrease the risk of hip fractures in elderly Korean women.

Mucopolysaccharidosis type II (MPS II) is a rare X-linked recessive lysosomal storage disease caused by mutation of the iduronate-2-sulfatase gene. The mutation results in iduronate-2-sulfatase deficiency, which causes the progressive accumulation of heparan sulfate and dermatan sulfate in cellular lysosomes. The phenotype, age of onset, and symptoms of MPS II vary; accordingly, the disease can be classified into either the early-onset type or the late-onset type, depending on the age of onset and the severity of the symptoms. In patients with severe MPS II, symptoms typically first appear between 2 and 5 years of age. Patients with severe MPS II usually die in the second decade of life although some patients with less severe disease have survived into their fifth or sixth decade. Here, we report the establishment of a preimplantation genetic diagnosis (PGD) strategy using multiplex nested polymerase chain reaction, direct sequencing, and linkage analysis. Unaffected embryos were selected via the diagnosis of a single blastomere, and a healthy boy was delivered by a female carrier of MPS II. This is the first successful application of PGD in a patient with MPS II in Korea.
