Sexually transmitted infections (STIs) pose a serious risk to women’s fertility and overall health, particularly among those in their reproductive years, according to a recent study published in Scientific Reports. The study highlights the growing concern of infertility spurred by such infections, noting that this has become a significant public health issue.
The authors stress that “infertility, especially infection-induced infertility, has become a critical issue in public health, significantly affecting family structure, marital stability, and social dynamics.” Recent data indicates that infertility rates are rising, with an increasing number of cases appearing in younger populations. According to the World Health Organization (WHO), approximately 1 in 6 people worldwide, or 17.5% of the adult population, experience infertility. This figure is even more alarming among women affected by STIs.
Chlamydia and gonorrhea, in particular, have been identified as infectious agents that heighten the risk of tubal factor infertility (TFI) and pelvic inflammatory disease (PID)—two leading contributors to female infertility.

To understand the global impact of STIs on maternal outcomes, researchers sought to analyze the effects of infectious diseases over a span of 30 years. They pointed out that “infection-induced infertility remains an under-recognized issue that warrants further research, with no comprehensive analysis available on its global burden.” The 2021 Global Burden of Disease (GBD) study provides essential resources for examining trends in infertility attributed to infections, focusing on variables such as age, socioeconomic status, and geographic location.
The GBD study, which encompassed data from 164 countries between 1990 and 2021, reported that the age-standardized prevalence rate (ASPR) of infertility due to infections showed a significant rise. The number of infertility cases linked to infections surged from nearly 11.3 million in 1990 to 19.15 million in 2021, with the ASPR escalating from 839.52 to 982.37 cases per 100,000.
The study’s findings reveal that “infertility has become a global health issue, impacting not only reproductive function but also overall health.” Over the three-decade span analyzed, significant disparities were observed geographically. Low socioeconomic regions bore the brunt of the burden but showed signs of improvement over time, while middle-to-high-income locations experienced rising rates of infection-related infertility.
In conclusion, the primary causes of global infertility attributed to infections were various STIs, particularly chlamydia. The study aims to inform policymakers about the urgent need for enhanced STI prevention and treatment initiatives. “This study offers detailed insights into the geographic distribution, age patterns, and temporal trends of infection-related infertility, highlighting the urgent need for targeted global and regional strategies,” the authors emphasized.
By providing a clearer understanding of this public health concern, the research underscores the critical importance of investing in STI prevention, screening, and treatment efforts to protect female fertility worldwide.
