A minimum of 25 to 30 percent of total calories from fat, with an emphasis on monounsaturated and saturated fats, supports optimal testosterone synthesis. The clients who make the biggest testosterone gains from lifestyle optimization alone are almost always the ones who were sleeping poorly. The protocol for testosterone-optimized sleep is specific. Menopause, which occurs as a woman ages, can lead to a lower amount of testosterone produced by the ovaries. Aging plays a crucial role in the development of low testosterone or testosterone deficiency in women. "Lab reference ranges are most often used when treating older menopausal women—so these ranges skew toward lower levels," Dr. Dorr explains. Like high testosterone, there’s no definitive range as to what is considered low testosterone, or hypogonadism, in women. If a woman has too much testosterone in her body, she may begin to notice changes to her physical appearance. Although testosterone may make prostate cancer grow, it is not clear that testosterone treatment actually causes cancer. For example, problem with function of pituitary gland or adrenal glands may lead to reduced testosterone production. For example, a man with osteoporosis and low testosterone can increase bone strength and reduce his fracture risk with testosterone replacement. Some men who have a testosterone deficiency have symptoms or conditions related to their low testosterone that will improve when they take testosterone replacement. All of this reduces the active (free) form of testosterone in the body. Among women, perhaps the most common cause of a high testosterone level is polycystic ovary syndrome (PCOS). In addition, what may seem like a symptom of testosterone excess (see below) may actually be unrelated to this hormone. Magnesium supports testosterone through multiple pathways including SHBG reduction, sleep improvement, and cortisol modulation. For most men, achieving optimal levels requires supplementation at 4000 to 5000 IU daily, particularly during winter months or for those with limited sun exposure. Studies show that men with vitamin D levels above 50 ng/mL have significantly higher testosterone than men below 20 ng/mL. It’s important to note that for people assigned female at birth (AFAB), there’s no exact number for determining high testosterone levels, also known as hyperandrogenism. High levels of testosterone in females may indicate polycystic ovary syndrome (PCOS), adrenal tumors, ovarian tumors, or hermaphroditism (having both female and male sex organs). Men can often feel a big difference when they stop therapy because their body's testosterone production has not yet recovered. On treatment, the body stops making testosterone. If a man's testosterone is below the normal range, it's best to repeat it once more to be sure before starting testosterone therapy - often staying on it indefinitely. Hone is an online clinic that helps men and women manage their health. Changes in mood, energy levels, or cognition might signal low testosterone levels.
