Introduction
The relationship between personality traits, particularly neuroticism, and childbearing has been a subject of interest in psychological and medical research. Neuroticism, a trait characterized by emotional instability and negative emotionality, may influence various aspects of reproductive behavior and outcomes.
Key Insights
-
Neuroticism and Male Fertility:
- Neuroticism is associated with decreased fertility in men, particularly those born after 1956. This trend is not explained by partnership status, income, or education.
-
Neuroticism and Female Fertility:
- There is no significant evidence that neuroticism independently affects female fertility or adverse obstetric outcomes, except for a potential association with gestational diabetes.
-
Neuroticism and Pregnancy-Related Symptoms:
- Neuroticism may act as a modifying factor in the relationship between biological conditions and nausea during pregnancy. Women with higher neuroticism may experience more nausea and vomiting, although this is not solely due to personality factors.
Conclusion
Neuroticism appears to have a more pronounced negative impact on male fertility compared to female fertility. While it does not significantly affect most obstetric outcomes for women, it may contribute to pregnancy-related symptoms such as nausea. Overall, neuroticism's influence on childbearing is more evident in men, potentially affecting their likelihood of becoming fathers.
