its oestrogens. some are metabolised away by the liver, but certainly alot is excreted by the kidney. i know because some tests look for it in urine. plus the action of the oestrogen in the wee helps keep the bladder and urinany tract hunky dorey. the vagina too. you don't wanna know what sorta things await you post menapausally...(Original post by Helenia)
It's not either oestrogen or progesterone that's tested for by a pregnancy test. It's human chorionic gonadotropin (hCG).
I'm not 100% sure of the metabolic fate of oestrogen/progesterone, but as I said, they were unable to find traceable levels of it in water near sewage outlets, where logically it would be at its highest.
