#shbg

anyway, my testes were damaged due to cryptorchidism and delayed surgery. pre-HRT my body was fully male otherwise, although I always had quite feminine features, small hands and feet, narrow shoulders and so on.

does this sound like intersex to you? I'm wondering if maybe my feminine proportions and cryptorchidism had a common origin.

So for a second I was confused how your gonads making a lot of hormones would fall under HYPOgonadism, but then you mentioned SHBG and then I was like, ohhhhh. Yeah, that would be a way how. I actually relate, because I produced low amounts of total testosterone, but because I have severely deficient SHBG, my unbound testosterone (androgens that can be used by the body's tissues and thus virilize) was double the typical range for female-typed bodies, thus I had mild clinical hyperandrogenism without hyperandrogenemia (high T in blood. or. biochemical hyperandrogenism). So if you have the inverse, high SHBG thus low unbound T... well there you go hypogonadism/hypoandrogenism symptoms.

So, to put your situation into Terminology TM. You seem to have a form of hypergonadotropic hypogonadism! "Hypergonadotropic" meaning your brain is sending out hormones to try and communicate with your gonads to produce sex steroids (usually in excess, because the HPG axis is often stuck in a repeating loop of "no response? let's make more!"), but said sex steroids i.e. androgens estrogens and progestogens, aren't produced or the body can't respond to them— thus hypogonadism.

thanks !

Entenda a diferença entre hormônios ligados e livres e a importância das proteínas carreadoras

Endocrinologia é o estudo das ações dos hormônios no organismo. Os hormônios são substâncias liberadas pelas glândulas endócrinas que podem agir em células próximas ou à distância. As glândulas endócrinas não tem ductos (canais) e liberam os hormônios diretamente na corrente sanguínea, diferente das glândulas exócrinas que liberam as substâncias por elas produzidas para o exterior do corpo ou…

Sex Hormone Binding Globulin, also known as SHBG, is an awesome little glycoprotein that most of us have never heard of. Since SHBH is related to testosterone and other sex hormones, many women remain in the dark about their SHBG status. But SHBG is an important biomarker for women to pay attention to! Read more to find out why.

What is Sex-Hormone Binding Globulin (SHBG)?

SHBG is a glycoprotein, a molecule that consists of a carbohydrate plus a protein, and is produced mainly in your liver. It binds to three sex hormones found in both men and women: estrogen, dihydrotestosterone (DHT), and testosterone. It's job is to transports these hormones throughout your blood to other tissues in your body. SHBG has a stronger affinity for DHT and testosterone (which are androgens), as compared to estrogens. It therefore plays a significant role in maintaining the delicate balance between estrogen and testosterone in a woman’s body.  

Why are optimal levels of SHBG important for women?

If you’ve been following the InsideTracker blog, you know that testosterone and other hormones play an important role in a woman’s overall physical and emotional health.  As a woman, you may have experienced times in your life when you knew your hormones were out of whack. SHBG makes sure that these hormones are transported throughout your body and are available for the tissues that need them. Optimal SHBG levels decrease a woman’s risk of developing polycystic ovarian syndrome, insulin resistance and type 2 diabetes.

Watch our free demo to learn how you can determine if your SHBG is at its optimal level.

What causes low SHBG levels in women?

SHBG levels decrease as a result of taking certain hormones, like androgens, anabolic steroids, and norethisterone-related synthetic progesterones. Certain conditions, like hypothyroidism, obesity, Cushing's syndrome, and acromegaly (a condition where your body produces too much growth hormone), can also cause low SHBG levels. Interestingly, insulin resistance, even without obesity, results in lower SHBG levels. 

Women with low levels of SHBGare more likely to have higher testosterone levels, which can lead to androgenization, i.e. the development of masculine characteristics. Low SHBH is often associated with polycystic ovarian syndrome. Other signs of low SHBG in women include: high levels of androgens, male-patterned hair growth or hair loss, menstrual irregularities, decreased breast tissue and skin abnormalities. Women with low SHBG are also at higher risk for developing cardiovascular disease, type 2 diabetes and Metabolic Syndrome.

What causes high SHBG levels in women?

 Compared to men, women naturally have higher levels of SHBG. The aging process, particularly for women, decreases SHBG levels, which means younger women tend to have higher SHBG levels than postmenopausal women.  Pregnancy increases SHBG even further, as SHBG is actually produced in the placenta tissue. Some evidence suggests that continuous use of oral contraceptives can also increase your SHBG levels. Finally, undernourishment, as seen in anorexia nervosa, and estrogen or thyroid hormone treatment can cause higher than normal SHBG levels in women.

Women with high levels of SHBG have less available testosterone in their bodies. That’s bad news for any lady since testosterone (another biomarker measured by InsideTracker) plays a important role in maintaining energy levels, muscle development, bone health, and your sex drive! 

What’s next?

SHBG is an important biomarker… but it’s just one piece of the puzzle in the roadmap to optimal health for women. InsideTracker can help provide you with more of the whole picture by analyzing your levels of 30 blood biomarkers related to optimal wellness.
