Short- and long-term clinical skin effects of testosterone treatment in trans men.

Introduction: Our knowledge concerning the effects of testosterone (T) therapy on the skin of trans men (female-to-male transsexuals) is scarce.

Aim: The aim of this study was to evaluate the short- and long-term clinical effects of T treatment on the skin of trans men.

Methods: We conducted a prospective intervention study in 20 hormone naive trans men and a cross-sectional study in 50 trans men with an average of 10 years on T therapy.

Voice in female-to-male transsexual persons after long-term androgen therapy.

Objectives/hypothesis: The aim of the present study was to 1) document voice in a large sample of female-to-male transsexual persons (FMT), 2) compare their vocal characteristics with those of heterosexual biological males, and 3) determine hormonal factors with impact on their fundamental frequency.

Study Design: This was a controlled cross-sectional study. It is the largest study to date on voice and voice change in FMT, and the first to include a control group and FMT who were under long-term androgen administration.

Reproductive wish in transsexual men.

Background: Hormonal therapy and sex reassignment surgery (SRS) in transsexual persons lead to an irreversible loss of their reproductive potential. The current and future technologies could create the possibility for female-to-male transsexual persons (transsexual men) to have genetically related children. However, little is known about this topic.

Methods: A single-center, cross-sectional study in 49 transsexual men (mean age 37 years) after long-term testosterone therapy and on average 8 years after SRS.

Sexual desire in female-to-male transsexual persons: exploration of the role of testosterone administration.
