Gender-affirming hormone therapy can impact liver health in transgender individuals. Careful monitoring is crucial to prevent liver damage, especially during COVID-19 infection.
Area of Science:
- Endocrinology
- Hepatology
- Public Health
Background:
- Transgender individuals undergo hormonal therapy for physical transition.
- Hormonal treatments involve testosterone for trans men and estradiol with anti-androgens for trans women.
- These therapies can potentially cause liver damage.
Purpose of the Study:
- To highlight the risks of liver damage associated with gender-affirming hormonal therapy.
- To emphasize the increased risk of hepatic complications due to the interaction between COVID-19 and hormonal treatments.
- To advocate for vigilant monitoring and care for transgender patients undergoing these treatments.
Main Methods:
- Review of existing literature on hormonal gender-affirming treatments and their hepatotoxic effects.
- Analysis of the impact of COVID-19 on hepatic tissue.
- Discussion of clinical considerations for managing liver health in transgender patients.
Main Results:
- Hormonal cross-sex therapies carry a risk of hepatotoxicity.
- COVID-19 can affect liver health through various mechanisms.
- Combined effects of hormonal therapy and COVID-19 may exacerbate liver damage.
Conclusions:
- Liver integrity is a significant concern in transgender individuals on long-term hormonal therapy.
- Close monitoring, including laboratory tests and clinical observation, is essential.
- The COVID-19 pandemic necessitates special attention to minimize hepatic risks in this population and improve healthcare access.

Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Liver Physiology
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
