Oestrogen

(Oestradiol)

Oestradiol is the main naturally occurring oestrogen in your body.

Together with regulating the reproductive system and secondary female characteristics, it also has an impact on the health of other tissues and organs including bone, liver, fat and the brain. In men, it’s important in the maturation of healthy sperm and maintenance of sex drive. Low levels can cause erectile dysfunction, sleep problems, joint pain, anxiety and a low mood.
