Impact of Lifestyle on Women's Infertility and Health Outcomes

Key Factors Contributing to Female Infertility

The rise in infertility cases, particularly in developed countries, has prompted a closer examination of modifiable lifestyle factors. Heavy drinking, smoking, obesity, and various health conditions such as hypertension and diabetes have been linked to infertility. Understanding these factors is essential for developing effective prevention and treatment strategies.

Lifestyle Factors Impacting Infertility

1. Heavy Drinking: Women who engage in heavy drinking (defined as consuming more than 8 AUDIT questionnaire points, which equates to at least monthly binge drinking) exhibit a significantly higher risk of infertility. A meta-analysis indicates a decrease in fecundability with increased alcohol consumption (Jeon et al., 2025) [1].

2. Smoking: Smoking has been associated with reduced ovarian function and increased risks of infertility. Women who smoke have a higher incidence of both primary infertility and complications during pregnancy (Jeon et al., 2025) [1].

3. Obesity: Although a higher body mass index (BMI) is often linked with reproductive complications, the current study found that being overweight was negatively associated with infertility. This unexpected result may be due to the timing of health check-ups and how they relate to pregnancy outcomes (Jeon et al., 2025) [1].

4. Health Conditions: Underlying health conditions such as hypertension, diabetes, and chronic kidney disease have been shown to negatively influence fertility. These conditions can disrupt hormonal balances critical for ovulation and overall reproductive health (Jeon et al., 2025) [1].

5. Underweight: Interestingly, being underweight also poses a risk for infertility, as it is associated with menstrual irregularities and anovulation (Jeon et al., 2025) [1].

The Role of Alcohol and Smoking in Infertility

Alcohol and smoking have longstanding reputations as detrimental to reproductive health. The current investigation highlights that women with infertility were more likely to engage in these behaviors compared to those who have given birth. For instance, 44.1% of women experiencing infertility were heavy drinkers, compared to 39.1% of those who had given birth. Similarly, past/current smoking was reported by 10.2% of infertile women versus 8.4% in the childbirth cohort (Jeon et al., 2025) [1].

Health Conditions Linked to Female Infertility Statistics

The study also found that women with infertility had higher rates of certain health conditions compared to those with childbirth experiences. Conditions such as hypertension (2.5% in infertile women vs. 2.0% in the childbirth group) and diabetes (15.0% vs. 13.3%) were more prevalent among women diagnosed with infertility. Furthermore, women experiencing infertility were more likely to be diagnosed with kidney function loss (33.4% vs. 28.8%) and menstrual disorders (38.7% vs. 35.9%) (Jeon et al., 2025) [1].

Benefits of Lifestyle Modifications for Enhancing Fertility

The findings indicate that certain lifestyle modifications could enhance fertility outcomes. The emphasis on preconception care is crucial as it aims to boost reproductive health through lifestyle adjustments. For instance, reducing alcohol consumption and quitting smoking can significantly improve fertility prospects. Furthermore, managing weight through a balanced diet and regular physical activity can enhance overall health, thus potentially improving reproductive outcomes (Jeon et al., 2025) [1].

Health Checkup Outcomes

Regular health checkups, as part of the General Healthcare Screening Program, can help identify underlying health conditions that may affect fertility. Notably, the study highlighted that women diagnosed with infertility had higher odds of being underweight but lower odds of being overweight compared to those who had experienced childbirth, suggesting the importance of maintaining a healthy weight for reproductive health (Jeon et al., 2025) [1].

Implications of National Health Insurance on Infertility Treatment

The expansion of the National Health Insurance (NHI) coverage for infertility treatments in South Korea reflects a growing recognition of the need for comprehensive reproductive healthcare. As of January 2024, the NHI includes coverage for up to 20 in vitro fertilization (IVF) attempts and intrauterine insemination (IUI) procedures without income restrictions. This policy shift aims to reduce the financial burdens associated with infertility treatments and increase access to necessary medical interventions (Jeon et al., 2025) [1].
