The concomitant use of testosterone in these informal reports, however, makes it difficult to know whether it was minoxidil, testosterone or their combination that was responsible for apparent improvement. The choice of medical interventions varies and is often influenced by the desire to acquire particular masculine characteristics and/or avoid certain side effects. Trans and gender diverse (TGD) individuals have a gender identity that differs from their sex assigned at birth. Many individuals worry about the possibility of sexual side effects, including erectile dysfunction, low libido, or ejaculation disorders, when using Minoxidil.
Some people speculate that Minoxidil affects sexual health, masculinity, or libido due to its supposed link to testosterone. For those who experience signs of low testosterone, consider adjusting medications under a doctor's supervision. However, the effects seem to be modest and reversible.
Maintaining healthy testosterone levels is important for overall health and wellbeing in men. Given the potential for systemically absorbed minoxidil to have adverse cardiovascular and fetal developmental effects (16, 24), clinicians and individuals should be aware of this possibility. This desire for some but not all masculinizing effects is often seen in individuals assigned female at birth who have a non-binary gender identity. Secondly, for individuals desiring testosterone but yet to access it, minoxidil may enable partial masculinization and thus help with GD and reduce misgendering.
Since 1997, topical minoxidil has been available over-the-counter and, whilst oral minoxidil has adverse cardiovascular effects, side effects of topical administration have so far been limited to reversible hypertrichosis, pruritis and local skin irritation (16, 18–20). The other was a randomized, double-blinded, placebo-controlled trial of 3% minoxidil solution involving 48 Thai men, and which demonstrated a significant increase in facial hair counts after 16 weeks of treatment (14). Currently, however, there are no recommended treatments used to specifically stimulate facial hair development in transmasculine individuals. The majority of these individuals have a transmasculine identity, and testosterone is frequently used to induce reversible changes such as android fat redistribution and increased muscle mass, as well as irreversible changes such as a deeper voice and increased facial/body hair growth (10, 11). While testosterone therapy in transgender males is generally effective in inducing masculinization, some adolescents encounter barriers to accessing such treatment or may not wish to experience all the changes that usually accompany testosterone. Our specialists confirm that Minoxidil does not significantly affect female testosterone levels either. While testosterone is a primary factor in male hair loss, women also use Minoxidil to treat thinning hair.
These are more likely in people with naturally low blood pressure, since Minoxidil is a vasodilator (it relaxes blood vessels). Minoxidil doesn’t increase testosterone, reduce it, or significantly influence how it’s processed in the body. Other treatments, like Finasteride (Propecia), work by reducing the amount of DHT in the body. DHT is a by-product of testosterone, converted in the body by the enzyme 5-alpha-reductase. Studies suggest that around 60–70% of men see improvement in hair density with consistent use. This supports healthier follicle function and, in many cases, leads to visible regrowth.
So how exactly does minoxidil impact testosterone? Testosterone is an important hormone that regulates many processes in the body and contributes to characteristics seen as "masculine" like muscle mass and body hair. At the time of writing, he continues to use minoxidil intermittently, which is a testament to his ongoing satisfaction with its effects.. However, due to legal requirements in Australia at the time, he was required to obtain Family Court approval to initiate therapy with testosterone.|These instances are very uncommon and do not seem to be connected to changes in testosterone levels. A common question is whether Minoxidil affects female hormones, particularly testosterone. According to dermatologists, Minoxidil’s effects are topical and not systemic, meaning it does not affect testosterone production or alter its function in the body. Minoxidil works locally on the scalp, targeting hair follicles without entering the bloodstream significantly. One of the most common concerns people have when considering Minoxidil is whether it has any impact on testosterone levels. This condition is influenced by both genetic predisposition and hormone levels, particularly testosterone.|Minoxidil is an FDA-approved, topical treatment used to stimulate hair regrowth, particularly for people experiencing male and female pattern baldness. Rest assured, Minoxidil does not affect testosterone levels or cause hormonal disruptions. However, it is essential to consider potential indirect effects and interactions, particularly in individuals with underlying medical conditions or those taking other medications.|Another study published in the British Journal of Dermatology evaluated the effects of 2% and 5% minoxidil solutions on hormone levels in men and women with androgenetic alopecia. It works by increasing blood flow to the hair follicles, providing them with essential nutrients and promoting hair growth. Minoxidil is a widely used medication for treating hair loss, but like any medication, there are concerns about potential side effects and interactions with the body's systems. Minoxidil remains a safe and effective treatment for hair loss with no established link to increased testosterone. Finasteride blocks the enzyme that converts testosterone into DHT, thereby addressing the hormonal cause of hair loss. In men genetically sensitive to DHT, this hormone causes hair follicles to shrink and eventually stop producing hair—hence the progression of male pattern baldness. So what does this mean for those using minoxidil products like Rogaine for hair loss?}
Thirdly, some TGD individuals may wish to masculinize without experiencing all the effects expected with testosterone. In this case report, we describe the use of minoxidil 5% lotion with good effect in a trans male adolescent prior to and continuing after testosterone therapy. His subsequent medical transition, which included bilateral mastectomy at age 18, has continued to proceed well and he currently remains on testosterone therapy under the care of adult gender services.
