Objective: To survey knowledge about the factors that influence fertility in a reproductive-age population living in an urban area. Methods: A cross-sectional study was conducted using a questionnaire-based survey among both males and females aged 18-45 years living in the Bangkok metropolitan area. Results: The mean age of the participants was $26.8{\pm}7.2years$ (male, 41.9%; female, 58.1%). Of the participants, 53.1% had an undergraduate degree and 57.1% were single. Only one-fifth of the participants correctly identified the age when fecundity declines in male and female, the definition of infertility, and the period during the menstrual cycle with the highest chance of pregnancy. Approximately three-fourths of the participants correctly identified that cigarette smoking, alcohol consumption, and sexually transmitted infections affect fertility. Conclusion: A considerable knowledge gap about the factors that influence fertility was identified in reproductive-age individuals in an urban area of Thailand. This issue should be urgently addressed by promoting fertility awareness through education, discussions about social perceptions regarding fertility, and reliable sources of knowledge.

Dysmenorrhea is the most common gynecological disorder in women of reproductive age. The prevalence of menstrual pain is relatively high and has been shown to be related to many factors like age, age at menarche, menstrual cycle regularity, parity, cigarette smoking, and dietary habits etc. This study was conducted to determine the possible link between dysmenorrhea and the factors related to it. We investigated the associated risk factors that could influence menstrual pain. This Cross Sectional Study was conducted at Dept. of OBG, NIUM, Bangalore. The study consisted of 230 women between the ages of 20 - 49 years. Included volunteers were newly married, nulliparious and parous women. The detailed reproductive history was recorded and was analyzed statistically. It was observed that there were only two factors that were influencing Dysmenorrhea namely the early age at menarche and increase parity. It was hypothesis that earlier start to reproductive life in some way decreases the sensitivity of the uterus to prostaglandin, whereas delayed menarche and postponing reproductive life increase sensitivity of the uterus to prostaglandins and cause severe menstrual pain. It is concluded that early age at menarche and high parity decrease menstrual pain.

Objectives: This study examined the reproductive health status and the work-related factors of female hairdressers. Methods: This study conducted by structured questionnaire from April 21th to May 20th. The study population of 316 were female hairdressers aged 15 to 60 years in Seoul. This study analysed the influencing factors, health related factors and work related factors on reproductive health using chi-square and multiple logistic regression analysis. Results: 1. The 81.7% of the subjects aged under 29 years have unhealthy behaviors. The 47% of hairdressers experienced smoking. Among the total, 37% of them answered they are smoking at present. Those results reveal their working conditions were very stressful to cope as young females. 2. The use of hair dyes(OR=2.89, 95%CI:1.17-7.12), counteractive solutions(OR=3.20, 95%CI:1.04-9.83) and not wearing protective gloves(OR=2.81, 95%CI:1.11-7.12) are significantly associated with menstrual pains. 3. The hairdressers not using perm liquids were three times as likely to report regular menstruation compared with the hairdressers using perm liquids. Wearing protective gloves also was associated with regular menstruation. Conclusion: This study revealed various risky working conditions of hairdressers was associated with their reproductive health. This study suggests that we should pay more attention to the protective working conditions for reproductive health. More comprehensive health management program including reproductive health for female hairdressers is required as well.

Infertility is a complex disease characterized by extreme genetic heterogeneity, compounded by various environmental factors. While there are exceptions, individual genetic and genomic variations related to infertility are typically rare, often family-specific, and may serve as susceptibility factors rather than direct causes of the disease. Consequently, identifying the cause of infertility and developing prevention and treatment strategies based on these factors remain challenging tasks, even in the modern genomic era. In this review, we first examine the genetic and genomic variations associated with infertility, and subsequently summarize the concepts and methods of preimplantation genetic testing in light of advances in genome analysis technology.

A commonly held view in studies of character displacement is that character states of both species are shifted in areas of sympatry. This view has been confirmed in an overwhelming number of cases for ecological character displacement. Excluding species pairs in which one of the two interacting species is found only within the distribution of the other species and species displaying gynogenesis, the pattern of reproductive character displacement is asymmetrical in that the shift in character states between areas of symaptry and allopatry occurs in only one of the two interacting species. Hypotheses for the reasons behind this asymmetry in reproductive character displacement include (1) homogenization by gene flow, (2) other mechanisms of reproductive isolation, and (3) sufficient reproductive isolation being provided by one of the interacting species exhibiting a pattern of reproductive character displacement. Because reproductive isolation can be achieved by divergence at any point in a sequence of premating reproductive behaviors and postmating developments, it is necessary to understand the mechanisms of reproductive isolation of two interacting taxa in areas of sympatry and allopatry and to analyze the relative contributions of potential factors to reproductive isolation to disentangle hypotheses for the patterns of asymmetry.

Objectives: This study was peformed to identify the related factors on Vietnamese immigrant women's reproductive health problems. Survey Participants were 231 immigrant vietnamese woman who lived at six cities in Korea. Methods: The comprehensive PRECEDE model comprised of diagnosis and planning curricular targeted or immigrant women aged 15-49. Data collection was conducted by face-to-face interview survey. Results: 1. The influential variables of recognition of reproductive health problems from the logistic analysis were using contraceptives (p=0.002), relationships with partners (p=0.000), the need of family planning (p=0.007), social support (p=0.009). This means that they experienced reproductive health problems when they did not use contraceptives, did not need family planning, did not receive social support and had close relationships with their partners. Conclusion: The basic data were provided for prevention of reproductive health problems such as unwanted pregnancy and abortion, as well as improved understanding of the different views on pregnancy, birth culture and sexual and reproductive health between Korea and Vietnam.

Objectives: This study was to develop a reliable and valid instrument measuring the reproductive health promoting behavior of undergraduates. Methods: The initial questionnaires were made of 106 items from four domains through literature review. All questionnaire items were revised by an expert group and a pilot test. Data were collected using the revised initial questionnaire of men's 58 items and female's 64 items from 634 male and 685 female undergraduate students. The collected questionnaires were analyzed by factor analysis using varimax rotation to evaluate the construct validity. Results: According to the gender, two measurement were invented and analysed separately. Four common factors consisting of 'safe sex', 'sexual responsibility', 'genital health management' and 'STD prevention' were discovered in both groups. The 'genital hygiene' factor was added as a female factor. Male students' scale was made up 4 factors 16 items and female students' scale was made up 5 factors 18 items. Cronbach's alpha for male scale was estimated to be .892 and female scale to be .882. Conclusions: This scale will make it possible to measure the level of reproductive health among Korean university students. This scale may be useful for developing effective methods of education as well as policy programs for improving the reproductive health of Korean university students.
