In males, the surge of testosterone causes the larynx (voice box) to grow larger, and the vocal cords within it thicken and lengthen. Whether through the natural process of male puberty or via gender-affirming hormone therapy, the impact of testosterone on the voice is profound and lasting. In accordance with sperm competition theory, testosterone levels are shown to increase as a response to previously neutral stimuli when conditioned to become sexual in male rats. Studies have shown small or inconsistent correlations between testosterone levels and male orgasm experience, as well as sexual assertiveness in both sexes. Perhaps you’ve always felt your voice was too high-pitched, or maybe you’re looking to project more authority and gravitas. The desire for a deeper voice is a common aspiration for many individuals. The decrease in estrogen levels causes extensive changes in mucous membranes, including the larynx. Taking TRT can result in voice deepening, but it takes six to nine months to see the full effect. Studies have shown that testosterone treatment affects the voice of transgender men. Any further significant changes would likely be due to medical conditions, hormonal imbalances, or aging. The Adam’s apple, a part of the larynx, becomes more prominent. They aim to optimize your existing vocal mechanism, not to force it into unnatural positions. For some, subtle improvements in richness and resonance might be noticed within a few weeks of consistent practice. It depends on several factors, including your starting point, the consistency and quality of your practice, your natural vocal physiology, and how quickly you grasp the techniques. While self-study can yield results, working with a qualified vocal coach can significantly accelerate your progress and ensure you’re practicing safely and effectively. 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. The testes produces less testosterone, there are fewer signals from the pituitary telling the testes to make testosterone. Before we delve into techniques, it’s absolutely crucial to understand the fundamental biological underpinnings of vocal pitch. This fascination, for me, was the initial spark that led me down the rabbit hole of understanding vocal production and, eventually, to explore the nuances of how to make your voice deeper permanently. First of all, the amount of testosterone in the body influences the voice. Whether or not testosteorne replacement therapy will make a trans man's voice deeper depends on a number of factors. Around 10% of males receiving prescribed anabolic steroids report a lowering of their voice pitch and frequency. The first is the challenge hypothesis which states that testosterone would increase during puberty, thus facilitating reproductive and competitive behavior which would include aggression. Men who produce more testosterone are more likely to engage in extramarital sex. There has been speculation that these changes in testosterone result in the temporary reduction of differences in behavior between the sexes. In addition, a continuous increase in vaginal sexual arousal may result in higher genital sensations and sexual appetitive behaviors. While testosterone therapy can influence voice pitch in adulthood, its effects are limited compared to pubertal changes. Combining hormone therapy with structured vocal training yields the best results for individuals seeking significant voice changes. If you naturally have a high-pitched voice, testosterone therapy might lower it slightly, but the extent of change depends on your genetics and current hormonal levels. In women, correlations may exist between positive orgasm experience and testosterone levels. 2020 guidelines from the American College of Physicians support the discussion of testosterone treatment in adult men with age-related low levels of testosterone who have sexual dysfunction. For women with PCOS, hormones like birth control pills can be used to help lessen the effects of this increased level of testosterone. The brain is also affected by this sexual differentiation; the enzyme aromatase converts testosterone into estradiol that is responsible for masculinization of the brain in male mice. Some of these effects may decline as testosterone levels might decrease in the later decades of adult life. Adult testosterone effects are more clearly demonstrable in males than in females, but are likely important to both sexes.
