Teenage hormonal shift surprises scientists – opposite impacts on kidney injury

Researchers found that female sex hormones may increase susceptibility to kidney injury during puberty, contradicting the protective effects seen in adulthood. The study suggests that developmental changes driven by the hormonal surge in puberty may override the benefits of female sex hormones later in life.
