Impact of Testosterone on Self-Esteem and Dysphoria
Testosterone can play a significant role in improving self-esteem and alleviating dysphoria-related depression. For some individuals, the changes brought about by increased testosterone levels can lead to a more positive self-image and a reduction in feelings of gender dysphoria. As one user shared, "If you're depressed, it's not physiologically because of your testosterone level in the same way that cis men may experience depression due to low T. However, you might find that the changes that come along with increased testosterone levels improve your self-esteem in a way that helps alleviate dysphoria-related depression." – shaggyyguy source.

Health Implications of Low Testosterone
Having zero testosterone levels can lead to various health issues, including lowered bone density, increased risk of osteoporosis, and negative effects on mood, energy, physical strength, stamina, and sleep. These deficiencies can result in a miserable and unhealthy state, potentially decreasing lifespan. As explained by another user, "The most prominent effect of not having enough sex hormones in your body is lowered bone density and significantly heightened risk of osteoporosis. But it will also affect your mood, energy levels, physical strength, stamina, ability to get restful sleep, etc." – am_i_boy source.

Social Comparison and Mental Health
Social comparison can significantly impact mental health, especially when individuals compare themselves to others on social media. This can lead to feelings of inadequacy and negatively affect self-esteem. One user noted, "I spend a lot of time comparing myself to other guys that come up on social media so that probably doesn't help." – boy0nscreen source.

Gradual Nature of Changes on Testosterone
The changes brought about by testosterone are gradual and can be likened to going through puberty again. This process takes time, and individuals may need to be patient as they adjust to these changes. As one user described, "T takes forever; it’s basically like going through puberty as a man this time, so it is supposed to take years." – Particular_Radio5215 source.

Conclusion
Navigating the effects of testosterone on mental health involves understanding its impact on self-esteem, health, and social dynamics. While low testosterone can lead to various health challenges, increased levels may improve self-esteem and alleviate dysphoria. It's important to be patient with the gradual changes and mindful of social comparisons. Embracing these insights can empower individuals on their journey to better mental well-being.
