Impact of Hormone Therapy on Serum Lipids in Transgender People

The term “Transgender” is used to describe individuals whose gender identity is different from their external sexual anatomy at birth. The number of people identifying as transgender has increased in recent years, and consequently, the number of gender affirmation surgeries and the use of hormonal therapies has also increased. A wide range of hormonal therapies has emerged considering the target population, age, and final outcomes, and as such these are becoming increasingly developed and complex in order to be the most appropriate for each individual. However, the side effects of these therapies remain to be fully understood. Therefore, this review aims to assess the impact of hormone therapy, in both transgender men and women of different ages, on the lipid profile. From the studies analyzed, it is possible to conclude that there is a relationship between hormone therapy and the lipid profile, with different outcomes between transgender men and women. There is a reduction in cardiovascular risk for transgender women as opposed to transgender men, in whom cardiovascular risk seems to increase due to lipid changes. It is now necessary to understand the mechanisms involved in order to reduce the consequences of these therapies and promote positive health outcomes.
