The median GAHT follow-up duration was 34.0 (interquartile range 17.2) months. Mean hemoglobin (HB) and hematocrit (HCT) levels increased by 16% (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.001) during testosterone treatment, decreased by 10% (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.01) during estrogen treatment, and plateaued after one year. During the initial follow-up, no clinically relevant changes were seen in glucose and lipid metabolism, BMI, or BP. Adverse effects leading to testosterone dose reduction were reported in 19% of transgender males and were less common when gonadotropin-releasing hormone analog was used in testosterone treatment initiation (11.1% vs. 27.8%,\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = 0.04).

No serious somatic adverse effects occurred. Regular measuring of HB and HCT in transgender males undergoing GAHT is warranted, but excessive monitoring of glucose and lipid metabolism, BMI, and BP during the initial follow-up period may not be necessary for somatically healthy adolescents.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1089\/trgh.2024.0012","type":"journal-article","created":{"date-parts":[[2024,12,20]],"date-time":"2024-12-20T11:34:22Z","timestamp":1734694462000},"page":"306-315","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Metabolic and Anthropometric Changes and Adverse Effects in Finnish Adolescents Using Gender-Affirming Hormonal Treatment"],"prefix":"10.1177","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1310-3431","authenticated-orcid":false,"given":"Nico","family":"Vehmas","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, University of Helsinki and Helsinki University Hospital, Helsinki, Finland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elina","family":"Holopainen","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, University of Helsinki and Helsinki University Hospital, Helsinki, Finland."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanna","family":"Savolainen-Peltonen","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, University of Helsinki and Helsinki University Hospital, Helsinki, Finland."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,8,7]]},"reference":[{"key":"e_1_3_6_2_2","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2017-01658"},{"key":"e_1_3_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.rhm.2015.11.008"},{"key":"e_1_3_6_4_2","doi-asserted-by":"publisher","DOI":"10.1089\/trgh.2017.0031"},{"key":"e_1_3_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jadohealth.2016.06.012"},{"key":"e_1_3_6_6_2","first-page":"e11","article-title":"Committee Opinion No. 685: Care for transgender adolescents","volume":"129","author":"ACOG","year":"2017","unstructured":"ACOG.
