Global Infertility Cases Predicted to Rise, Here Are the Triggering Factors

The number of women experiencing infertility globally is estimated to reach 80 million cases by 2036. This figure represents a 1.5-fold increase compared to approximately 53.6 million cases in 2023, with the largest increase expected to occur among women aged 35 to 39 years.

These findings refer to the latest research published in The Lancet journal. The researchers noted that the increase is primarily driven by more women postponing childbirth until a more mature age. As age increases, the ovarian reserve and the ability of eggs to be fertilised decline. This condition leads to decreased fertility, increases the risk of miscarriage, and reduces the success rate of assisted reproductive technology.

“As population ageing and socioeconomic transitions accelerate, the number of women at risk of infertility at an older age continues to rise, making this issue increasingly important for public health,” the researchers said, as quoted by Euronews on Wednesday (8/7/2026).

The study analysed data from the Global Burden of Disease 2023, covering 204 countries and territories over the period from 1990 to 2023. The analysis results show that the largest increase in infertility occurred in more developed countries. In many developing countries, infertility is also on the rise due to various lifestyle and social changes. For instance, women today tend to marry and start having children at a more mature age. Unfortunately, in many developing countries, access to fertility examinations and treatments remains limited due to high costs.
