Aging | IGF1 gene therapy in middle-aged female rats delays reproductive senescence through its effects on hypothalamic GnRH and kisspeptin neurons

Researchers found that IGF1 gene therapy increases kisspeptin expression and GnRH release, and alters microglial cell numbers, suggesting a potential protective effect against reproductive decline. This could lead to new strategies for optimizing lifespan and combating age-related health problems in women.
