Testosterone can cause several permanent changes to the body, even after hormone therapy is stopped. These effects are primarily related to masculinization.
Here's a breakdown of the permanent effects of testosterone:
Permanent Changes Due to Testosterone
These changes are typically irreversible, even after testosterone administration is discontinued.
-
Voice Deepening: Testosterone thickens the vocal cords, resulting in a permanently lower voice. The degree of change varies from person to person.
-
Clitoral Growth: Testosterone stimulates the growth of clitoral tissue, resulting in permanent enlargement.
-
Body and Facial Hair Growth: Testosterone increases the density and thickness of body and facial hair. While hair growth may slow down or change somewhat after stopping testosterone, the increase in hair follicles is generally permanent. Once hair follicles are stimulated by androgens, they typically remain active.
-
Balding (Male Pattern Baldness): In individuals genetically predisposed, testosterone can accelerate or trigger male pattern baldness. This is due to the conversion of testosterone to dihydrotestosterone (DHT), which affects hair follicles. This hair loss is typically permanent unless interventions like hair transplants are used.
-
Potential Irreversible Effects on Fertility: Testosterone can significantly impact fertility, and while not always guaranteed, reduced sperm production or infertility can be permanent. The extent of fertility impact varies based on duration of use, dosage, and individual factors. It is important to discuss fertility preservation options with a healthcare provider prior to starting testosterone therapy.
Summary Table
| Effect | Permanence | Description |
|---|---|---|
| Voice Deepening | Permanent | Thickening of vocal cords, resulting in a lower pitched voice. |
| Clitoral Growth | Permanent | Enlargement of the clitoris. |
| Body/Facial Hair | Permanent | Increased growth and thickness of hair on the body and face; while growth rate might change, follicles remain. |
| Balding | Permanent | Acceleration or triggering of male pattern baldness in genetically predisposed individuals. |
| Fertility Impact | Potentially Permanent | Possible irreversible reduction in sperm production or infertility, dependent on individual factors and duration/dosage of testosterone use. Consult a doctor for fertility preservation. |
It is crucial to have a thorough discussion with a healthcare provider about the potential permanent effects of testosterone therapy before starting treatment. Understanding these changes allows for informed decision-making regarding hormone therapy.
