1. Estriol belongs to natural hormone and is the metabolite of
estradiol in vivo , anti estrogen steroids . It is mainly presented
in the urine . Estrogen has a relative small activity with the oral
activity being 6 times as high as estrone but being weaker than
estradiol with non-carcinogenic effects . After its administration
, the in vivo estradiol levels did not change . Estriol has
selective action on the vaginal and cervical canal but has no
effect on the uterus and endometrium entity .
2. Animal experiments have shown that estriol has a stronger effect
on vaginal epithelial keratosis than estradiol , thus being able to
promote vaginal epithelial hyperplasia , superficial cells
keratosis , mucosal angiogenesis and vaginal epithelial wound
healing , but having a weak effect on the weight gain of mouse
uterus . At the same time , estriol can enhance the function of
cervix cell , causing the cervix muscle fiber hyperplasia and
increasing the cervical elasticity and softness .
3. In addition , estriol has feedback inhibition on the
hypothalamus and pituitary but does not inhibit ovulation while
only having significant impact on the corpus luteum and therefore
can be used as the auxiliary drug in the medium-term labor
induction and artificial abortion and for the treatment of various
kinds of menopathy . Estriol also has significant effect on the
hematopoietic system and can reduce vascular permeability and
fragility. Therefore , it can be used for the treatment of various
kinds of hemorrhage . It also has effect of rapidly increasing the
peripheral leukocytes and generally begins to take effect at 1 to 3
days after treatment but with a shorter duration of action and is
effective in treatment the leukopenia induced by radiotherapy and
