>>This is a whole story by itself.
Initially, starting in the 1970’s, the urine was obtained from menopausal Italian nuns who would leave jugs of pee for the drug company Serono to pick up in the mornings. Menopausal women have really high amounts of FSH in their blood, and most of it comes out in the urine.
The pee would be taken to a factory with a swimming pool-sized pee vat, and they would somehow get the FSH from the pee. Serono went on to be the most profitable company in the world. The Catholic Church was rewarded for its cooperation.
Even today, pee swimming pools exist for companies who make fertility drugs from urine.<<
