Atopic Dermatitis and Infertility: A Nationwide Retrospective Cohort Study

Area of Science:

• Dermatology
• Reproductive Medicine
• Epidemiology

Background:

• Atopic dermatitis (AD) and infertility share common pathophysiological factors.
• Large-scale epidemiological data on the association between AD and infertility are limited.

Purpose of the Study:

• To investigate the potential association between atopic dermatitis and infertility in a large, community-based population.
• To determine if AD is a risk factor for infertility.

Main Methods:

• A nationwide retrospective cohort study was conducted.
• Compared 127,150 patients with AD to 127,071 matched controls.
• Subdivided participants by age (adults/children) and AD severity (mild/moderate-to-severe).

Main Results:

• Patients with AD showed a higher prevalence of infertility (1.4%) compared to controls (1.1%).
• Infertility prevalence per 1,000 patient-years was higher in AD patients (2.17) versus controls (1.7).
• Multivariate analysis confirmed AD as a key risk factor for infertility in both males and females across all severity levels.

Conclusions:

• A significant association between atopic dermatitis and infertility was identified.
• Infertility may represent an additional clinical manifestation of atopic dermatitis.
• Further research is recommended to explore the interplay between AD management and infertility treatment.
