Effect of obesity on natural fertility in women of reproductive age : a literature review

Abstract

The global prevalence of obesity has risen substantially over the recent decades, while also raising concerns about its impact on women’s reproductive health, especially in women within their reproductive age. Obesity has been associated with multiple risk factors such as hormonal dysregulation, ovulatory dysfunction and even adverse metabolic changes that may impair natural fertility. This literature review aims to examine and synthesize current evidence regarding the relationship between obesity and natural fertility in women of reproductive age. This review explores proposed biological mechanisms, including endocrine and metabolic alterations, as well as observed effects on ovulatory function and time to conception. By summarizing existing research, this review highlights the potential impact of obesity on natural fertility and underscores the importance of weight management in reproductive health.
