Objective: As paternal age increases, the quality of sperm decreases due to increased DNA fragmentation and aneuploidy. Higher levels of structural chromosomal aberrations in the gametes ultimately decrease both the morphologic quality of embryos and the pregnancy rate. In this study, we investigated whether paternal age affected the euploidy rate. Methods: This study was performed using the medical records of patients who underwent in vitro fertilization (IVF) procedures with preimplantation genetic screening (PGS) from January 2016 to August 2017 at a single center. Based on their morphological grade, embryos were categorized as good- or poor-quality blastocysts. The effects of paternal age were elucidated by adjusting for maternal age. Results: Among the 571 total blastocysts, 219 euploid blastocysts were analyzed by PGS (38.4%). When the study population was divided into four groups according to both maternal and paternal age, significant differences were only noted between groups that differed by maternal age (group 1 vs. 3, p= 0.031; group 2 vs. 4, p= 0.027). Further analysis revealed no significant differences in the euploidy rate among the groups according to the morphological grade of the embryos. Conclusion: Paternal age did not have a significant impact on euploidy rates when PGS was performed. An additional study with a larger sample size is needed to clarify the effects of advanced paternal age on IVF outcomes.

Purpose. This study was conducted to compare the paternal rearing behavior and rearing stress level between fathers with a preschooler and fathers with school children so that it can be utilized as a basic source for developing parental rearing education programs. Methods. A descriptive comparative methods was conducted to identify the paternal rearing behavior and paternal rearing stress. Respondents were 361 fathers who had either preschoolers (n=189) or children of elementary age (n=l72). Results. Comparing the two group's means, the rearing activity score and rearing stress there were significant differences. In the school children's group's father, 'outdoor activity' and 'guidance on discipline activity' were significantly higher than the other group. In the preschool children's fathers group, 'play interaction activity' was statistically significant higher than the other, and the child-part mean score of paternal rearing stress was significantly higher than the other group. The correlation between paternal rearing behavior and paternal rearing stress, it can be shown that more paternal rearing behavior means less paternal rearing stress. Conclusion. These results of this study will help design rearing program for fathers that have either preschool children or school children by providing the basic data for paternal rearing behaviors and paternal rearing stress.

This study examined the effects of parental control and children's autonomy on self-esteem, using a sample of 415 school-age children (208 boys and 207 girls) recruited in Seoul. Ordinary Least Square regressions revealed a variety of gender-based differences in the associations among these three variables. Boys with high maternal behavioral control had high levels of self-esteem, whereas girls under low paternal psychological and high behavioral control reported high levels of self-esteem. Boys with high maternal behavioral control and girls with high paternal behavioral control also reported high levels of autonomy. Autonomy was found to exert a positive impact on self-esteem for both boy and girls. Autonomy played a mediating role in the relationships between maternal behavioral control and self-esteem for boys, and between paternal behavioral control and self-esteem for girls. These findings highlight the differential influences of psychological control and behavioral control on autonomy and self-esteem, as well as the relative impact of the opposite sex parent on the development of autonomy and self-esteem in late childhood.

Using ethnographic methods, this study identified the meaning of paternal experience through 1 to 2 hours of individual interviews with the fathers of preschool children. The interviewees were 33 middle-class fathers from 28 to 41 years of age, Twenty had infants under 36 months of age the others had preschool children 37 months of age and older. Results were summed up with two statements : The first is that paternal experience with the under 36-month-old infants can be called "the stage of adjustment". The other statement is that paternal experience with 37-months and older preschool children can be called "the stage of model-building as a father".

Purpose: This study aimed to analyze the impact of advanced maternal and paternal age on perinatal outcome in Korea. Methods: We conducted a retrospective study involving 1,622 Korean women who delivered at M Woman Hospital from January to December 2010 and their spouses were included. We obtained obstetrics database which included demographic characteristics, medical and obstetrics history, course of the current pregnancy and advised perinatal outcome. Multivariable logistic regression was used to adjust for potential confounding variables. Results: Women giving birth age 35 or older were statistically significant in paternal age, gravidity, spontaneous abortion experience, method of conception, method of delivery, and multiple gestation compared to women aged <34 years. After adjusting for the confounding effects of maternal characteristics, women aged 35 or older were at increased risk for cesarean section delivery (adjusted OR 1.6, 95% CI 1.22-2.13) and preterm birth (adjusted OR 2.2, 95% CI 1.03-4.63). Conclusion: In this population of Korean women, advance maternal and paternal age is independently associated with specific adverse perinatal outcome, especially preterm birth and cesarean section delivery.

The purpose of the study was to investigate whether there were differences between the Paternal child rearing Involvement and the Parental Satisfaction according to child's sex, father's age and the birth order of child. The subjects surveyed were 271 fathers 132 in their thiries and 139 in their forties who live in Kwang-ju. And the children considered are 128 boys and 143 girls. Among them, first-born children are 143 members, second-born are 103, and third-born are 25. Factor analysis, frequencies, mean, standard deviation, Cronbach's α, one way-ANOVA, Pearson's correlation coefficient, and step-wise regression are used for data-analysis. The main results were as follows : (1) There were some significant differences in the Paternal child rearing Involvement according to the child's sex, while there was no difference as related the father's age and the birth-order of child. (2) The were some significant differences in the father's Parental Satisfaction which is involved child's sex and the father's age, but there was no difference as to the birth-order of child. (3) There were some significant differences between the Paternal Child rearing Involvement and the Parental Satisfaction, and between its subfactor and the Parental Satisfaction, too. (4) The result of the step-wise regression, which analyses the Paternal child rearing Involvement and the background variables as to father's Parental Satisfaction, shows the Parent-child relationship variable (accounted for about32% of the general variation), spouse support, support of children, general satisfaction, and parent's role conflict at intensity in order. Of the above mentioned five fields, house-activities were the first factor in determining this order. And the personal interaction plays an important role in fulfilling general satisfaction and the support of children. The leisure-action factor was the second explanatory factor in establishing the parent-child relationship. Finally father's age was the fourth explanatory factor in assessing the parent-child relationship variable considering the background variables.

Background: Retinoblastoma is a rare malignant intraocular neoplasm. About 90% of cases feature a germline mutation in the RB1 gene and these will develop retinoblastoma during their early childhood. An association between mutations in germline cells and aging has been demonstrated. This suggests a higher incidence of childhood cancer including retinoblastoma among children of older parents. Materials and Methods: In the present study we aimed to determine the association of paternal and maternal age with an increased risk of retinoblastoma in a case-control study in Iranian population. The study was carried out on 240 persons who were born during 1984-2012 in Mahak and Mofid hospitals in Tehran, Iran. The statistical analysis included studying the mean age of parents and in order to know whether parental age of patients is different from parental age of control group, (t-test) compare averages test is used perfectly. By binary logistic regression, odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Results: The results of statistical analysis including the study of mean parental age by the use of (t-test) compare averages test showed a significant difference between parental ages of patients and controls. Logistic regression showed that coefficients were significant for maternal but not paternal age. Conclusions: Our findings indicate that advanced maternal age can increase the risk of retinoblastoma in offspring, but the paternal age has no significant effect.

Using ethnographic methods, this study identifies the meaning of paternal experiences through a series of individual one to two hour interviews with men who have grandchildren. The interviewees consisted of twelve fathers from fifty to seventy years of age and the middle SES class. The results were as follows. First, adult-children-marriage and parent transitions were found to be important changes for men on their father's perception of their role as a father. Second, fathers with grandchildren felt happiness due to their grandchildren and held grandchildren as being important. Third, protecting and supporting their families was the main focus of paternity. Forth, the period of paternal experiences with grandchildren can be called "the stage of strong grandfather identity" because men who have grandchildren put more importance in the relationship with grandchildren than do their own adult-children, and grandchildren themselves play an important role in establishing male identity.
