A form of Estrogen: There are three forms of naturally occuring estrogen in the body, estrone, estradiol, and estriol. Estriol is the most commonly used and recommended form of estrogen for menopausal symptoms. Estriol has great benefit to the cells of the vagina but has little effect on the breast or the uterine lining when used conservatively.

During the first week after menses (or during the menses or right before menses, the estrogen levels will be very low- and that is normal). Ideally, hormone levels are checked on day 21-23 of menstrual cycle. ...Read more

Hello, I was prescribed 0.5 mg of estriol vaginal gel to use daily for vaginal burning? It worked for 2 months, then stopped. What else can I use?

Hello,
I was prescribed 0.5 mg of estriol vaginal gel to use  daily for vaginal burning?  It worked for 2 months, then stopped.  What else can I use?

Vaginal burning: It may be a coincidence that the burning stopped. Burning can be caused by a number of organisms, namely yeast or bacterial. Estrogen vaginal gel may improve only hormonal deficits , and not really deal with the origin of the symptoms. See your provider and get a culture done of the vaginal secretions to make certain there is no infection. ...Read more

Where is information on normal levels of progesterone, estradiol, estriol, testosterone & dhea?

Lab reference ranges: Levels of these hormones are only as reliable as their test kits. One lab may use a different method for detection than another. You may not be able to compare values between different labs. Labs also set their normal ranges based on multiple tests. You need to discuss these hormones with an endocrinologist as they're trained to understand the different testing methods. ...Read more

51 female, used estriol cream. After 1 month, my hair began falling out! i read some convert estrogens to androgens. What tests should I ask doc for?

51 female, used estriol cream. After 1 month, my hair began falling out! i read some convert estrogens to androgens. What tests should I ask doc for?

Can test androgens: But Estrogens don't/can't be converted into androgens (it's the other way around, the androgens get converted into estrogens). But your doctor can test your androgen levels. Unfortunately, hair loss is a difficult problem to diagnose the cause of and to correct. Usually thyroid and iron levels as well as biotin levels can be checked. ...Read more

I'm on testosterone therapy, i keep hearing that some of it converts to estrogen. Does it convert to estrone or estrodiol or estriol or all three?

I'm on testosterone therapy, i keep hearing that some of it converts to estrogen. Does it convert to estrone or estrodiol or estriol or all three?

Estradiol: Estradiol is synthesized via aromatase from testosterone. Estrone is synthesized via aromatase from androstenedione. Estriol is synthesized from both Estradiol and estrone. Estradiol is ~10 times as potent as estrone and ~80 times as potent as estriol in its estrogenic effect. In some men on t replacement, too much t is converted to Estradiol and may require a drug like Arimidex (anastrozole) to block. ...Read more
