While the most pronounced vocal changes occur during puberty, testosterone levels can continue to influence the voice throughout adulthood. There are also individuals who would like to achieve a deeper voice without having to commit to a regime of hormone therapy to do so aor the potential systemic effects of testosterone. Testosterone plays a fundamental role in shaping the larynx and vocal cords, leading to a deeper voice in those with high testosterone exposure. However, testosterone therapy may slightly thicken the vocal cords over time, which could contribute to a deeper resonance. Speech therapy and vocal exercises are frequently used in both transgender voice training and professional voice coaching to refine pitch, resonance, and vocal control. Furthermore, conditions such as hypogonadism, where the body produces insufficient testosterone, can result in higher-pitched voices in men, underscoring the hormone’s crucial role in vocal modulation. A voice that resonates well in the chest and lower pharyngeal areas will sound deeper and richer, regardless of the exact fundamental pitch of the vocal cords. Agnathans (jawless vertebrates) such as lampreys do not produce testosterone but instead use androstenedione as a male sex hormone. Total levels of testosterone in the body have been reported as 264 to 916 ng/dL (nanograms per deciliter) in non-obese European and American men age 19 to 39 years, while mean testosterone levels in adult men have been reported as 630 ng/dL. When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game. For example, the genitals may not enlarge, facial and body hair may be scant, and the voice may not deepen normally. Learn all about the sex hormone here, including its primary benefits. What's more, testosterone plays other important roles in health and disease that may surprise you. The presence of these ubiquitous steroids in a wide range of animals suggest that sex hormones have an ancient evolutionary history. They named the hormone testosterone, from the stems of testicle and sterol, and the suffix of ketone. Testosterone's bioavailable concentration is commonly determined using the Vermeulen calculation or more precisely using the modified Vermeulen method, which considers the dimeric form of sex hormone-binding globulin. Several professional medical groups have recommended that 350 ng/dL generally be considered the minimum normal level, which is consistent with previous findings.non-primary source neededmedical citation needed Levels of testosterone in men decline with age. As a result, testosterone which is not bound to SHBG is called free testosterone. The part of the total hormone concentration that is not bound to its respective specific carrier protein is the free part. Fairer offers from test subjects with higher testosterone in the original study increase the likeliness of the offer being accepted by the negotiating partner, therefore decreasing the probability of both participants leaving without any money. This additional information could suggest, contrarily, that testosterone may encourage greed or selfishness. However men with high testosterone were significantly 27% less generous in an ultimatum game. Test subjects with an artificially enhanced testosterone level generally made better, fairer offers than those who received placebos, thus reducing the risk of a rejection of their offer to a minimum. The size of vocal folds depends largely on the size of larynx. These differences emerge at puberty, when testosterone causes the cords to grow thicker and longer. Based on the research and observations, the answer is a resounding yes; testosterone influences voice depth. HRT Guru further supports this evidence, noting that the voice-deepening effect is irreversible. The relationship between testosterone and voice has been examined from various angles. This article delves into existing studies and research to uncover the truth behind testosterone and its role in voice modulation.

For those seeking more dramatic results, voice masculinization surgery is something to be considered. For many, it’s a last-resort option that can significantly improve confidence and gender alignment. As a result, there is some controversy about which men should be treated with supplemental testosterone. Women may have a testosterone deficiency due to diseases of the pituitary, hypothalamus or adrenal glands, in addition to removal of the ovaries. Although testosterone may make prostate cancer grow, it is not clear that testosterone treatment actually causes cancer. Men taking testosterone replacement must be carefully monitored for prostate cancer. There are times when low testosterone is not such a bad thing. Affected women may experience low libido, reduced bone strength, poor concentration or depression.
