“…While we focused on maternal factors, the paternal factor exert an effect, too. We saw some increase in birth weight with increasing age of the father, as other studies have previously shown, 20 although in our study, the effect was confined to the age range 25‐29 years. Unfortunately, we could not consider paternal weight or height.…”

Aim We investigated whether birth order is an influencing factor for birth weight independent from maternal factors. Methods Data were obtained from the longitudinal cohort study LIFE Child and included 1864 children, of which 526 were only children. The 1338 siblings were ranked into first‐borns (n = 570), second‐borns (n = 606) and third‐or‐later‐borns (n = 162). Children born prematurely, suffering from chronic or syndromic diseases, were excluded. We performed intra‐family comparisons to reduce bias and assessed the impact of perinatal parameters, such as birth order on birth weight, using mixed models. Results Birth weight increased with birth order. In univariate analyses, birth order had a significant effect on birth weight‐SDS with second‐borns having 0.29 SDS (app. 130 g) and third‐borns 0.40 SDS (app. 180 g) higher values than first‐borns (P < .001). Maternal pregnancy weight gain was associated with higher birth weight‐SDS (P < .01) in univariate analysis, though maternal pregnancy weight gain was lower for higher birth orders. Multivariate analyses revealed that being a second or third‐or‐later‐born child had a stronger impact on birth weight than all maternal factors. Conclusion Birth order must be considered a potential risk factor for higher birth weight. Maternal pregnancy weight gain is not the driving factor for higher birth weight in siblings.

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 of study was two and half years, from Nov, 2007 to Apr, 2010. Inclusion criteria were pregnant women with age 20 – 35 years irrespective of parity. Exclusion criteria were known medical illness in either partner, induced abortion and recurrent miscarriages. Studied paternal factors were age, tobacco use and genital tract infection. Data was computed using SPSS version 16. Significance of paternal factors was determined by Logistic Regression Analysis. Results : Total cases studied were 200, while there were 400 controls. Mean maternal age was 27.6±4.9 years in cases and 26.5±4.5 years in controls. Mean paternal age was 35.5±6.2 years in cases and 32.3±5.4 years in controls. Paternal age was >35 years in 54.5% cases and 16.8% controls. Spearman Bivariate correlation revealed paternal age > 35 years (p=0.000) and genital tract infection (p=0.043) as significant factors. Only paternal age >35 years (p=0.000) remained significant in Final Model after entering into logistic regression. Conclusion: Paternal age beyond 35 years was found to be significantly related to first trimester spontaneous miscarriages.

“…However, other studies have found such poor outcomes only in children of teenaged fathers, with no increased risk with APA [20] or, in a large study of all births in Ohio from 2006 to 2012, no associations were found with paternal age at all, including preterm birth, growth restriction, and NICU admission [57]. In contrast, a large study of infant check-up data at one Japanese medical center found increased birth weight with advanced paternal age, but only in non-first-born children and growth parameters at 1 month of age were no longer associated with paternal age [59].…”

Many factors, including postponement of marriage, increased life expectancy, and improved success with assisted reproductive technologies have been contributing to increased paternal age in developed nations. This increased average paternal age has led to concerns about adverse effects of advanced paternal age on sperm quality, assisted reproductive outcomes, and the health of the offspring conceived by older fathers. This review discusses the association between advanced paternal age and sperm parameters, assisted reproduction success rates, and offspring health.
