Testosterone is the major androgenic hormone. It is responsible for the development of the male external genitalia and secondary sexual characteristics. In females, its main role is as an estrogen precursor. In both genders, it also exerts anabolic effects and lo behavior. In men, testosterone is secreted by the testicular Leydig cells and, to a minor extent, by the adrenal cortex. In premenopausal women, the ovaries are the main source of testosterone with minor contributions by the direch and peripheral tissues.
Testosterone Test: Free & SHBG, High vs. Low vs. Normal Levels
Although they vary greatly between men and women, normal free testosterone levels are important starting points for anyone considering testosterone replacement therapy. For both men and women, free testosterone is one of the most important measures of hormonal health. You might not technically have low free testosterone, but you might still have testosterone levels that are too low for your body.
We do this for both men and women — and this is especially important for women, where the amounts involved are much smaller making precision that much more important. Here are the normal free testosterone levels for both men and women. We often see mostly female patients who are diagnosed with excessive testosterone, when in reality, they have too little testosterone.
Their free testosterone levels have not been measured correctly, and the role of sex hormone binding globulin SHBG has not been assessed properly. SHBG has a perfectly descriptive name — it binds to your sex hormones, and, along with albumin, renders them effectively inert. And if you have too much SHBG in your body, even if your total testosterone is normal or even high!

Cessation of opioids, regular workouts and other lifestyle changes can definitely set the stage for improved testosterone production. Testosterone can certainly induce weight gain, but this would be by an increase in lean mass. I have seen no evidence, in the literature or in clinical practice, that would suggest that TRT would make someone gain fat. This is invariably due to other factors that include dietary habits and caloric expenditures.
Improving a low free testosterone level will help in improving body composition when coupled with exercise and a healthy diet. This does not necessarily mean that one would lose weight, but it would not lead to an increase in body fat.

A small bit of cardio will help as well. This is not a common response. I would assume mismanaged estradiol levels may be playing a part in that. I am not sure why you would want to, but if you sleep poorly and infrequently, consume a lot of alcohol and trans fats, never work out or have sex, and focus on coping with stress in unhealthy ways, you would be sure to see a reduction in your free testosterone levels. I am a female over 50 and get testosterone pellet therapy. My recent blood levels show my total testosterone is a little high but my free testosterone is negligible.
Normally when my free is negligible, my gynecologist puts in another pellet, however this time he is wanting to wait a few wks because my total testosterone is higher than normal range. Why would this happen and is it bad to have the pellet placed especially if my free testosterone level is severely low.
That being said, managing your care by your total T levels vs. It is typical for females to need a much higher than normal total testosterone level to achieve a desirable free testosterone level.
My sex hormone binding globulin is My free testo calc Can you please tell me your opinion.

Furthermore, your symptoms are almost certainly influenced by testosterone deficiency. Based on this information alone, and without the benefit of a full medical history, physical exam, and confirmatory labs, I would say that you are correct.
If this is a well established, properly diagnosed, and worsening process, then TRT may in fact be your best option. There are many things to be considered, however, so make sure that you find an experienced provider for a second opinion. Hello, I am 55 yo female with successfully treated hashimotos tsh normal with good t4 and t3 and treated mild bipolar II and depression. I must keep my tsh at a very sold range to alleviate depression.
I am post menopausal. My hormones are dhea , progesterone. I am not overweight but I try to be very fit and am petite. I have seen very positive benefits from TRT with patients who have diagnoses similar to yours. Additionally, I have not seen any adverse effects specific to bipolar disorder with the addition of TRT. I am a female aged 32, feel like I have low testosterone but confused by the blood test results. My total testosterone is Does this look like low testosterone?
The mismatch appears to be due to utilization of a bad test. Per The Endocrine Society, a direct or analog free testosterone assay is clinically useless. Make sure they look at your calculated free T, with your total only being 13, you almost undoubtedly have a low free testosterone. I am 59 and have been on androgel for about 10 years.
My test came back showing my free Testosterone at Your range is different. The most important thing to evaluate is whether they are even using the same test. I agree with The Endocrine Society in saying that this test is clinically useless. Now, each individual reference lab is at liberty to create their own reference range. It changes from lab to lab, and even analyzer to analyzer. The range we use, however, is the most widely accepted and matches up with the calculated free testosterone range that Blue Cross Blue Shield uses.
My libido and performance have fallen greatly in the past year and a half. I would suggest first having your calculated free testosterone looked at. The free testosterone direct assay is terribly flawed and clinically useless. You will have a much better understanding of your levels once you have the right metrics.

Your estradiol very well may be elevated, and yes, this could increase your SHBG level, and that could create a testosterone deficiency, and yes that COULD be linked to antidepressants.
Only careful monitoring and comparison to baseline labs could correlate that, though. I have a blog about my journey on TRT where I write articles I think are relevant for others to read. Maybe you can help me, or point me in the right direction to find the answers. Why is so much of our testosterone bound? Why do we need so little free testosterone in our blood compared to total testosterone? This will be more than I can cover here, but the free hormone theory is not specific to testosterone.
Albumin is the most ubiquitous blood protein, and binds to a myriad of substances. Think of this as a buffering and reserve system. Bound testosterone is inactive, only free molecules can bind to androgen receptors and affect change. There is a constant production, binding, cleaving, conversion, and metabolism chain going on within the body.
