CHICAGO — Cross-sex hormone treatment of transgender adults leads to very few long-term side effects, according to the authors of the largest study to date to examine this issue.
More than 2000 patients from 15 US and European centers participated in the retrospective study, called Comorbidity and Side Effects of Cross-Sex Hormone Treatment in Transsexual Subjects, and nearly 1600 received at least 1 year of follow-up, the authors reported.
“Our results are very reassuring,” principal investigator Henk Asscheman, MD, PhD, who heads HAJAP, his clinical research company in Amsterdam, the Netherlands, told Medscape Medical News. “There are mostly minor side effects and no new [adverse events] observed in this large population.”
Speaking at ICE/ENDO 2014 last week, where he presented the initial results of the research, Dr. Asscheman said the data confirm findings from smaller studies published in the past decade.
“The take-home message,” he said, “is that when using the guidelines from the Endocrine Society [“Endocrine Treatment of Transsexual Persons”], you are not going to see a lot of comorbidities with cross-sex hormone treatment.”
