Infertility Research Highlights Diet Benefits for Men and Rising Female Rates

A study by researchers at Universitat Rovira i Virgili in Spain found that men who eat at least seven servings of nuts per week—a roughly 30‑gram daily portion—show significantly better semen quality. Participants consuming this amount had higher sperm concentration and total count, with a 75% lower chance of reduced sperm motility and a 69% lower risk of abnormal seminograms. Replacing nuts with ultra‑processed snacks was linked to poorer semen parameters.

Another analysis published in The Lancet Obstetrics, Gynaecology & Women’s Health reports a global increase in infertility among women aged 35‑49. In 2023, 53.6 million women in this age group were affected, and the number is projected to rise to 79.6 million by 2036. The rise is observed across all regions, especially in Asia, and reflects broader demographic ageing and higher demand for fertility services. The authors call for expanded, affordable infertility care and integration of services into primary health systems to mitigate the growing public‑health and economic burden.
