Oestriol (E3) [Saliva]

Oestrogens are a group of multiple hormones including E1, E2 and E3. In women, oestrogens are secreted directly by the ovaries or made in adipose cells by conversion from DHEA-S and testosterone. In men, oestrogen hormones are made to a lesser extent in the testes.

The pattern of circulating oestrogens in the human body is:

Oestrone (E1) 10-20%

Oestradiol (E2) 10-20%

Oestriol (E3) 60-80%

Oestradiol (E3)
  • Produced almost exclusively during pregnancy
  • Topically may relieve postmenopausal vaginal atrophy and urinary incontinence
  • E2 is less potent than E1 and E2
