Aim: To study what medication fathers are being prescribed in the months preceding conception.
Methods: A retrospective cohort study of Danish national registries, comprising all births in Denmark 1997-2017 (1.3 million births). Time trends and absolute levels of paternal prescription medication in the 6 months prior to conception were assessed. While all medications were examined ( = 1335), we focused on the main medication groups, medications that have increased in use over time, and medications for which previous evidence exists of an effect on sperm quality.
Results: The average number of prescriptions increased over the study period (from 0.75 prescriptions to 0.82 per birth). Polypharmacy (three or more prescriptions) increased from less than 8% to 10% of fathers. The use of pain medication, proton-pump inhibitors, selective serotonin reuptake inhibitors and some inhalants have all increased markedly over the last 20 years.
Conclusions: Potential harm to the offspring done by paternal medication may present an increasing problem. As paternal medication exposure is increasing, examination of generational effects, such as major birth defects, is necessary.

Postpartum Mental Health Care Use Among Parents During Simultaneous Parental Leave.
JAMA Netw Open
October 2024
Centre for Health Equity Studies, Stockholm University/Karolinska Institutet, Stockholm, Sweden.
Article Synopsis
- Flexible parental leave schemes in Sweden allow both parents to take leave simultaneously during the first year after a child's birth, potentially impacting their mental health care usage; however, the effects of this on postpartum mental health are not well-studied.
- This cohort study investigates the link between simultaneous parental leave usage and postpartum mental health care uptake among parents in Sweden, analyzing data from national registries.
- The study assessed 207,283 parental dyads and found significant trends regarding mental health service use; however, detailed results on how simultaneous leave influences care uptake were not fully presented in the given text.
Antibiotic use and risk of autism spectrum disorder and attention-deficit/hyperactivity disorder: a population-based cohort study.
Child Adolesc Psychiatry Ment Health
July 2024
Graduate Institute of Clinical Pharmacy, College of Medicine, National Taiwan University, Taipei, Taiwan.
Background: The gut microbiota is believed to influence neurodevelopment through the gut-brain axis, but prior studies have shown inconsistent results regarding early childhood antibiotic exposure and subsequent risk of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). The purpose of this study was to evaluate the hypothesis that exposure to antibacterial agents in the first 2 years of life increases the risk of ASD and/or ADHD.
Methods: This was a retrospective cohort study using 2003-2019 data from the National Health Insurance Research Database in Taiwan.
Patterns of paternal medication dispensation around the time of conception.
Paediatr Perinat Epidemiol
August 2024
Department of Epidemiology, Harvard T.H. Chan School of Public Health, Boston, Massachusetts, USA.
Article Synopsis
- Research on prenatal medication safety has mainly focused on mothers, with little attention to the effects of fathers' medication use during the time leading up to conception.
- A study analyzed data from over 4 million pregnancies in the U.S. to identify the most common medications prescribed to fathers in the 90 days before conception.
- Results indicated that over a third of fathers filled prescriptions, with categories like psychotropics and antibiotics being common, some of which are known to pose risks to fetal health, highlighting a need for more research on paternal medication effects.
Development of a predictive model for pediatric atopic dermatitis: A retrospective cross-sectional nationwide database study.
Ann Allergy Asthma Immunol
September 2024
MYOR Diagnostics Ltd, Zichron Yaakov, Israel. Electronic address:
Background: The rise in prevalence of atopic dermatitis (AD) has been correlated with numerous elements of the exposome, modern-day lifestyle, and familial history. The combined analysis of familial history and other risk elements may allow us to understand the driving factors behind the development of AD.
Objective: To develop prediction models to assess the risk of developing AD using a large and diverse cohort (N = 77,525) and easily assessed risk factors.
Valproate Use During Spermatogenesis and Risk to Offspring.
JAMA Netw Open
June 2024
National Centre for Register-based Research, School of Business and Social Sciences, Aarhus University, Aarhus, Denmark.
Importance: Concerns exist about teratogenic and long-term neurodevelopmental outcomes of paternal use of valproate during spermatogenesis.
Objective: To evaluate the association between paternal use of valproate during spermatogenesis and offspring risk of congenital malformations and neurodevelopmental disorders.
Design, Setting, And Participants: This nationwide cohort study included 1 235 353 singletons born in Denmark between January 1, 1997, and December 31, 2017, identified in the Medical Birth Register; 1336 children had fathers who had filled prescriptions for valproate during spermatogenesis.
