Study projects global infertility cases could rise to 79.6 million by 2036
The analysis, drawing on data from 204 countries and territories from 1990 to 2023, warns infertility is likely to increase as women delay childbearing.
A large-scale study projects that infertility among women aged 35 to 49 could rise by almost half to about 79.64 million cases by 2036, citing increasing delayed childbearing. The research was published in The Lancet Obstetrics, Gynaecology, and Women’s Health in July, and it flags the issue as a major public health challenge for Hong Kong, where average maternal age is among the world’s highest.
According to SCMP Economy, the study was co-led by the University of Hong Kong, with research also led by Dr Zhou Niya of the Chongqing Centre for Women and Children’s Health. Researchers analyzed global health database data covering 204 countries and territories between 1990 and 2023, then used forecasting models to estimate future infertility prevalence.
The report said infertility at advanced maternal age should be addressed beyond clinical treatment, calling for stronger fertility education and earlier reproductive planning. Queenie Li Lingjun of HKU said the problem is connected to family well-being, reproductive autonomy, workforce planning, and long-term social development.
SCMP Economy reports the study traced long-term trends in infertility prevalence and concluded that, if current patterns continue, the number of cases in the 35 to 49 age group could increase to roughly 79.6 million by 2036.
