Re: One hormone becoming another

 I read that testosterone in men can become estrogen? I.e. its converted from testosterone into estrogen?

Yes, estrogen is formed in both and women from testosterone through the action of the enzyme aromatase.

Why does it do that, or why do we need that to happen?

Because both sexes have receptors, such as those in bones, that respond to estrogen.  Both sexes also have responses to testosterone, such as maintaining muscle mass as sexua| stimulation.   Also keep in mind what would happen if we only had single hormones without antagonization.  For example, if women only produced estrogen but did not produce testosterone to keep it in check. These hormones can cause various problems if left unopposed such as cancers, weigh gain, hypothyroidism, blood sugar problems, enlarge prostate, etc.

How does that happen? Dont we make estrogen (men) by itself, i.e. is the only way we get estrogen via testosterone?

Yes.

What converts testosterone into estrogen?

Aromatase.

Should it happen, or is there a way we can stop it?

There are ways to reduce the conversion such as nettle root, which is a natural aromatase inhibitor.  You do not want to completely block it though.

What issues in testosterone becoming estrogen could lead to high estrogen levels? I.e. could to much testosterone mean that youll get to much esotrgen as all the testosterone ultimately becomes estrogen?

Not really.  The amount of testosterone that converts in to estrogen is dependent on aromatase activity.  The higher the activity the the more testosterone is converted in to estrogen.
