1 in 8 males undergo scrotal surgery 20 years after kidney donation

A population-based cohort study found that the cumulative incidence of scrotal surgery among male living kidney donors was 1 in 8 after 20 years, compared to 1 in 143 for non-donors. Most males who donate a kidney won't develop this complication, but it's essential to inform past and future donors about the risk and potential symptoms.

How family size affects your health: New study reveals surprising patterns

The study found that having no biological offspring was linked to a higher risk of schizophrenia in both men and women. Having more than one offspring compared to one was associated with disease risks across multiple systems. Each additional offspring reduced mental and behavioral disorders by 7% and breast cancer risk by 18% for women.
