It has been suggested that bisphenol A (BPA), a known endocrine disruptor, interferes with the endocrine system, causing reproductive dysfunction. Recently, BPA has been found in waste water due to incomplete sewage purification, possibly threatening health through its ingestion via tap water. In this study, young male mice (6 - 7 weeks old) were administered water containing BPA (50 mg·kg^-1) for four weeks, while control mice consumed water without BPA. Serum, epididymal spermatozoa and testicular sections were assessed after sacrificing the mice on day 28. No significant differences were obtained between the groups in the body, testis and seminal vesicle weights. However, the epididymal sperm motility and count levels were significantly reduced in BPA-fed mice. Significantly higher hepatotoxicity levels were also observed in mice ingesting BPA as compared to the control mice. The level of serum testosterone was reduced, and testicular sections revealed incomplete and irregular spermatogenesis in BPA-ingested mice. The sperm proteasomal-proteolytic activity level has been implicated in sperm function and is measured in motile spermatozoa using fluorometric substrates. High ubiquitin C-terminal hydrolase activity levels were observed in the control mice without BPA. During a mating trial, a low pregnancy rate (71.4%) was observed in females mated with males who had consumed BPA (100% in the control mice). Overall, BPA adversely affected spermatogenesis and quality, as indicated by decreased sperm motility, concentration and serum testosterone levels, resulting in reduced fertility competence.

The purpose of this study is to examine the prevalence and correlates of three types of risk-taking behavior among high school students in Korea in a cross-sectional national sample. A sample of 636 male and 622 female high school students is analyzed using descriptive statistics and logistic regression. Three types of risk-taking behavior are examined: drinking alcohol, smoking, and premarital sex. The results are as follows: Forty-three percent of students in the sample have ever drunk alcohol, 32% have ever smoked, 11% have experience premarital sex. Risk-taking behavior is more prevalent among boys than among girls. Boys and girls in Seoul are much more likely to have experienced three types of risk-taking behavior. Not having two parents in the family and having lived away from immediate family increase the likelihood of some risk-taking behavior. Students who have a friend with premarital sexual experience are much more likely to have experienced premarital sex themselves. Among sexually active students, having multiple sexual partners is common and prevalence of condom use is low. Reproductive health education at school has no effect on students' sexual behavior. The prevalence of risk-taking behavior among adolescent in Korea is likely to rise in the future. Substantial proportion of adolescents are exposed to the risks of STDs and substantial proportion of adolescent girls risk premarital pregnancy. Current health education programs are inadequate in protecting students from risk-taking behavior. Students whose families do not include both parents and students who live away from their immediate families need special programs to protect them from risk-taking behavior.

Purpose: This study analyzes the effects of smoking behaviors of women of reproductive ages in terms of maternal conditions and conditions arising during the perinatal period in Korea. Methods: We used the National Health Insurance Corporation's medical panel data. Subjects included 382 individuals suffering from maternal conditions and conditions arising during the perinatal period from 2013 to 2014. A t-test was used to analyze the individual differences between maternal conditions and conditions arising during the perinatal period-A hierarchical regression analysis was performed in two steps to measure the effects of smoking behaviors on diseases. Results: The amount and duration of smoking are significant factors causing maternal conditions and conditions arising during the perinatal period. In the regression analysis, the explanatory power of model was significantly increased by adding smoking behavior to the maternal conditions and conditions arising during the perinatal period. Smoking behavior during pregnancy displayed a significant influence on diseases. Conclusion: Results of this study showed that the effects of smoking behavior on maternal conditions and conditions arising during the perinatal period were significant. Therefore it is necessary to develop a smoking cessation education program for pregnant women in Korea.

Objectives: To investigate the current prevalence and knowledge of cervical cancer, breast cancer and reproductive tract infections (RTIs) in rural Chinese women, and to explore the acceptance and feasibility of implementing a combined screening program in rural China. Methods: A population-based, cross-sectional study was conducted among women aged 30 to 59 years old in Xiangyuan County, Shanxi Province from 2009 to 2010. Socio-demographic characteristics, knowledge of cervical cancer, breast cancer and RTIs, and the attitude toward single or combined screening were collected by an interview questionnaire. Each participant received a clinical examination of the cervix, breast and reproductive tract. Examinations included visual inspection, mammography, laboratory tests and pathological diagnosis. Results: A total of 1,530 women were enrolled in this study. The prevalence of cervical precancerous lesions, suspicious breast cancer, suspicious benign breast disease and RTIs was 1.4%, 0.2%, 14.0% and 54.3%, respectively. Cervicitis, trichomonas vaginitis, and bacterial vaginitis were the three most common RTIs among our participants. Television, radio broadcast, and public education during screening were the major source of healthcare knowledge in rural China. Moreover 99.7% of women expressed great interest in participating in a combined screening project. The affordable limit for combined screening project was only 50 RMB for more than half of the rural women. Conclusion: A combined screening program would be more effective and popular than single disease screening projects, while appropriate accompanied education and a co-pay model for its successful implementation need to be explored, especially in low-resource settings.

Purpose: This study aimed to identify if participating in a sexual education program, influences knowledge, and healthcare attitude among attitudes of nurse clinicians in Korea. Methods: A cross-sectional study was conducted with 210 Korean nurse clinicians. Data were collected through self-reported questionnaires from July to August, 2011 from five hospitals in S and I cities. Data were analyzed using t-test, Pearson correlations, and multiple linear regression with SPSS/WIN 21.0. Results: This study reported that the majority of nurse clinicians had attended sexual programs about sexual harassment, reproductive system and function. There were significant correlations between experience of attending sexual education(r=.32, p=.003) and sexual knowledge(r=.14, p=.047) with sexual healthcare attitude. Sexual education on the job(${\beta}=.13$, p=.004), supplementary sexual education(${\beta}=.17$, p=.009), sexual knowledge(${\beta}=.16$, p=.048), and obstetrics and gynecology department carrier(${\beta}=.29$, p<.001) explained 14.0% of sexual healthcare attitude. Conclusion: This study's results demonstrate that advanced and continuous sexual health program is necessary for nurse clinicians. Proper sexual knowledge and positive attitude may promote nursing intervention and counseling concerning patients' sexual problems.

The purpose of this study is to provide fundamental information for the development of new sex education image media through the analysis of those tools produced by Planned Parenthood Federation of Korea. Twenty three video tapes related to the sex education were analysed. The data were sampled on the basis of the sex education instructions for primary and secondary schools published by the Seoul Office of Education in 1996 and the list of sex education information composed by the Planned Parenthood Federation of Korea with the following requirements. 1) The education materials are oriented to the middle and high school students as well a juveniles and are being used in public health centers and schools. 2) The education materials are not confined to the single subject such as AIDS or contraception. Because this study is focused on the analysis of image media, an analysis method widely and effectively used in public media study was chosen. The frequency analysis and percentage treatment were done by an SAS program. The results of the study are as follows : 1. An analysis of the material structure type showed that the frequency of the following subjects in 15 video tapes, composed as drama and cartoon, had this decreasing orde : sex behavior, sex relation ships, sex health, human development, personal technique, and society and culture. 2. The eight tapes of explanation and counseling showed a different sequence from that of the drama and cartoon material, primarily treating human development with 5419 seconds (47.9%) of type. The following were also considered in decreasing order: at 2000seconds (17.6%) sex behavior, at 1366 seconds (12.1%) sex health, at 1240 seconds (11.0%) society and culture, at 667 seconds (6.0%) relation ships, and at 611 seconds (5.4%) personal technique. 3. In a thematic analysis those education materials dealing with human development show this frequency sequence: anatomic physiology, reproduction, and adolescence. In relation, ships the sequence is dates, love, marriage and vows, and family. For personal technique, it is expressed as asking for help, and an empnasis on moral values. For sex behavior, they focus on abstinence, the co-responsibility of sex behavior, the sexual response of the human, and sexual nightmares. For the sex health area, the focus is contraception with abortion and reproductive health following that. In society and culture diversity is considered. 4. An analysis of the differences in production and content between 1980s and 1990s was also done. For materials produced in the 1980s the frequency of the subjects follows this order: sex behavior, human development, relation ships, sex health, personal technique, and society and culture with sub subjects such as abstinence, dating, adolescence, anatomic physiology, reproduction, calls for help, and the sexual response of a human being. For materials produced in the 1990s, highest frequency was sex behavior, the same as the 1980s. The rest of the material follows this decreasing order: relationships, human development, sex health, society and culture, and personal technique with sub subjects such as dating, co-resposibility in sex behavior, abstinence, and love frequently considered.

The purpose of this study is to provide substantial foundation to establish effective sex education plan for female college students. For this purpose, we compared female college students with health related majors and the ones with non-health related majors in knowledge in sex, attitude toward sex, and sexual experience. We took the form of self-recording to survey 269 single female college students. The result is as follows. For knowledge in sex, including reproductive organs, contraception, delivery, sexual disease, and sexual intercourse, students with health-related majors(20.59) gained higher scores than students with non-health related majors(16.82). Scores for attitude toward sex indicated 2.43 for the health related majors and 2.35 for the non-health related majors. Attitude toward pre-marital sex, sex admissibility, and abortion showed especially distinct result between the two groups. Whether a student has ever engaged in sexual intercourse served as a significant variable to determine knowledge in sex overall, and the indexes such as sexual pleasure, chasteness, marital values, and attitude towards sex indicated significant differences. The result may be interpreted that the students with sexual experience tend to show more open attitude toward sex. The result indicated that contraception, pregnancy, and delivery were the parts that the participants most wanted to be educated on. Knowledge in sex is both positively correlated with attitude toward sex and sexual behavior. Also, the result indicates that knowledge in sex, both subjective and objective, significantly affects sexual behavior.

Background: Polycystic ovary syndrome (PCOS) is a combination of chronic anovulation, obesity, and hyperandrogenism and can affect sexual function in women of reproductive age. It is also associated with endometrial cancer. Our aim was to evaluate the frequency and predisposing factors of sexual dysfunction in PCOS patients. Materials and Methods: In this cross-sectional study, 16 married women with a definite diagnosis of PCOS were recruited. Sexual function was assessed in the domains of desire, arousal, lubrication, orgasm, satisfaction and pain using the female sexual function index (FSFI) questionnaire. Patients were also assessed for mental health using the depression, anxiety and stress (DASS-21) questionnaire. Presence of hirsutism was assessed using the Ferriman-Gallwey (FG) scoring system. Demographic data were obtained from patients during in-person interview. Results: Sexual dysfunction was present in 62.5% of patients with the domains of arousal and lubrication particularly affected (93.8% and 87.5%, respectively). Patients with symptoms of depression and anxiety were significantly more likely to suffer sexual dysfunction than those without these symptoms (p=0.04 and p=0.03 respectively). Patients with stress symptoms reported higher orgasm dysfunction than those without (p=0.02). No significant difference in any of the FSFI score domains was observed between patients with and without hirsutism. Conclusions: PCOS patients markedly suffer from sexual dysfunction and therefore it seems appropriate to be screened for intervention. Poor mental health conditions that may be the result of infertility or other complications of PCOS should also be considered as curable causes of sexual dysfunction in these patients.

Purpose: This study was conducted to identify awareness levels in regard to preconception care and gender differences targeting single undergraduate students in their 20s. Methods: The study participants were 867 single undergraduate students aged 20~29 (523 women, 344 men). This was a descriptive research, in which awareness levels of preconception care and pregnancy were identified the through questionnaire surveys. Results: Gender differences in the awareness of reproductive care before conception were found. Generally, women's awareness of issues related to preconception care and pregnancy was higher than that of men. Women recognized risk factors in pregnancy ($x^2$=22.85, p<.001) and positive behaviors ($x^2$=10.91, p=.012) better than men. Women's awareness of preconception care was significantly higher than that of men (t=8.37, p<.001). The awareness levels of the students who completed a reproduction related class (t=3.16, p=.002) and the students who knew about folic acid (t=-10.78, p<.001) in preconception care were statistically significantly higher. Conclusion: The results indicate that the ways to educate and alert students to major risk factors before pregnancy and other reproductive care content before conception is to provide education both single women and single men.
