Paternal environmental conditions can influence phenotypes in future generations, but it is unclear whether offspring phenotypes represent specific responses to particular aspects of the paternal exposure history, or a generic response to paternal 'quality of life'. Here, we establish a paternal effect model based on nicotine exposure in mice, enabling pharmacological interrogation of the speci...

Paternal and nonpaternal voles (microtus) have different arginine-vasopressin (AVP) and oxytocin (OT) receptor patterns in the extended amygdala, a neural pathway associated with parental behavior. Using receptor autoradiography, the authors examined whether AVP and OT receptor patterns were associated with facultative paternal behavior in either sexually and parentally inexperienced or experie...

BACKGROUND AND OBJECTIVE Few studies have examined the relationship between paternal stimulation and children's growth and development, particularly in low- and middle-income countries (LMICs). This study aimed to estimate the prevalence of paternal stimulation and to assess whether paternal stimulation was associated with early child growth and development. METHODS Data from the Multiple Ind...

Although the adverse effects of maternal aging on reproductive outcomes have been investigated widely, there is no consensus on the impact of paternal age. Therefore, we investigated the effect of paternal age on reproductive outcomes in a retrospective analysis of 9,991 in vitro fertilization (IVF) cycles performed at the Reproductive Medicine Center of the Third Affiliated Hospital of Guangzh...

Background & aim: Marital satisfaction during pregnancy is one of the factors affecting marital affectional bond. This study was performed to evaluate the effect of paternal-fetal attachment training on marital satisfaction during pregnancy. Methods: This clinical trial was conducted on 60 couples referring to two health centers of Mashhad, Iran, in 2015. The couples were randomly divided into ...

This longitudinal study examines the relationship between earlier paternal drug abuse, environmental factors, paternal child-rearing practices, and adolescent vulnerable personality attributes and later adolescent aggressive behavior. Data were collected at two points in time, one year apart, via individual, structured interviews. Structural Equation Modeling (SEM) was used to assess the interr...

UNLABELLED Objectives : To determine whether paternal factors i.e., age, tobacco use and genital tract infection increase the risk for spontaneous first trimester miscarriage. Methodology : This case control study was conducted in the Department of Obstetrics & Gynaecology, Unit V / IV, Dow Medical College & Lyari General Hospital, Dow University of Health Sciences, Karachi, Pakistan. Duration ...

hybrids were produced by crossing female caspian kutum rutilus frisii kutum with male grass carp ctenopharyngodon idella. the genome of eight larvae and parents were studied using microsatellite markers for genetic evaluation and verification. after dna extraction from parent fish and progeny, hybrid heritability of two loci was assessed using two pairs of microsatellite primers. hybridizie...

BACKGROUND AND OBJECTIVE To date, most parent-based research has neglected the role of fathers in shaping adolescent sexual behavior and has focused on mothers. The objective of this study was to conduct a structured review to assess the role of paternal influence on adolescent sexual behavior and to assess the methodological quality of the paternal influence literature related to adolescent se...

Paternal age has been associated with offspring congenital heart defects (CHDs), which might be caused by increased mutations in the germ cell line because of cumulated cell replications. Empirical evidences, however, remain inconclusive. Furthermore, it is unknown whether all subtypes of CHDs are affected by paternal age. We aimed to explore the relationship between paternal age and the risk o...
