Researchers from Sweden, France and the United Kingdom have jointly analysed the immune response of transsians who have undergone hormone therapy and concluded that three months after treatment was started, their response becomes similar to that of cis man. This work, in addition to highlighting the importance of sex hormones in the immune system, has highlighted the gap in health research around transient people.
Researchers have recalled that sex, already known, significantly influences women's immune system. For example, women are 9 times more at risk for autoimmune lupus erythematosus than men. However, these differences have not yet been much investigated, let alone in trans people.
In the present study, the researchers themselves warn that the sample has been limited: 23 trans men. In any case, they have stressed that the result has been "very significant" for the organisation. All participants started hormone treatment after puberty and therefore have shown that, even after that age, it is sufficient to influence the immune system.
In addition, they think that research helps understand why, when testosterone has been taken for other reasons, the effects of male and female cysts are different, even before and after menopause.
