Article Synopsis
  • Cisplatin is a medicine that can harm the ovaries and uterus by causing stress to the cells, while Pycnogenol is an antioxidant that helps protect against this damage.
  • In a study with female rats, there were three groups: one group got only cisplatin, one group got both Pycnogenol and cisplatin, and the last group was healthy.
  • The results showed that the rats treated with Pycnogenol had better health in their ovaries and uterus compared to those only given cisplatin, meaning Pycnogenol helped to reduce the damage caused by cisplatin.
