echoed word on the web is that androstenedione is found naturally in the pollen of scotch pine trees. where is the data on this? if this can be confirmed, it could then be added to the entry proper.
This article uses both the term "Estrodiol" and estradiol. Is one a typo for the other? Are they alternate spellings? Or possibly different chemicals? Or are the different chemicals, but one is still a typo here? -- Karada 13:11, 9 Feb 2005 (UTC)
- This is a typo. There are several google sites with the same typo where estradiol is meant.Ekem 28 June 2005 17:59 (UTC)
[edit] Production of testosterone
- This article said : the substance does not increase blood levels of testosterone, and does not increase muscle size or strength in young healthy men
- The FDA says : Although these compounds possess at most weak intrinsic androgenic activity, they are prohormones for both androgens (testosterone) and estrogens. The biochemical evidence supporting the effect of androstenedione to raise circulating levels of testosterone and estrogens is strong. This, in conjunction with the known potential for site-of-action direct conversion of androstenedione to testosterone, leads to a conclusion of a direct relationship between risk of androgenic or estrogenic effects of treatment and dose and duration of treatment. In particular, androstenedione and related molecules consumed in sufficient quantities to have any anabolic effects will confer androgenic and estrogenic risks, although risks may also be present with consumption that is not sufficient to produce obvious anabolic effects.. http://www.fda.gov/oc/whitepapers/andro.html
