Puberteit, testosteron en hersenontwikkeling
Effect van testosteron op hersenbeeldvorming en hoofdpijn bij transmasculine adolescenten
Transmasculine youth (female sex assigned at birth, male gender identity) who begin clinical gender affirming hormone therapy (GAHT) with testosterone (T) may experience changes in headache. Researchers think this because studies published on effects of giving testosterone to cisgender females (female sex, female gender identity) and transmasculine adults seem to show an effect on pain.
This research will help us learn more about changes in headache and in brain structure and function in transmasculine youth during the first year of T. Youth who will be starting T within 6 months, either on puberty blocker or not, as part of their regular medical care can participate and will be asked to attend 3 visits:
- before starting T
- after 6 months on T
- after 1 year on T
At the visits, they will be asked to:
- answer questions and surveys about their health
- have a brain MRI done
- give a small sample of blood
and at their first visit, complete a physical exam. Some participants can also do a brief test of pain sensitivity. All participants will be asked to complete a headache diary for the first 6 months and for 1 month after the 1 year visit.

Interventie / Behandeling
Gedetailleerde beschrijving
This will be conducted at Childrens Hospital Colorado (CHCO) Clinical & Translational Research Centers (CTRC) facilities. Physical examination will include vital signs, anthropometric measurements, and breast/pubic hair staging, as applicable, by a medical provider.
Visits will be in the morning to capture peak hormone levels.
The following questionnaires will be administered: PROMIS Pediatric Anxiety Short Form, PROMIS Pediatric Depressive Symptoms Short Form, and PedMIDAS form (headache disability measure).
The daily headache diary is tailored to be brief on days when no headache occurs, and to capture more detail including medications taken and headache and aura characteristics on days a headache does occur.
The medical chart will be reviewed for relevant health information and medications.
MR-based imaging will be conducted at the Brain Imaging Center at the University of Colorado Anschutz Medical Campus.

On blocker
Transmasculine youth who will begin taking testosterone clinically in < 6 months with or without headache and who have been on pubertal blocker, a gonadotropin hormone releasing (GnRH) agonist for at least 3 months. |
Clinical testosterone therapy No research interventions will be used as a part of the study since the research is observational. Testosterone treatment will be prescribed and followed by participant's clinical physician. |

No blocker
Transmasculine youth who will begin taking testosterone clinically in < 6 months with or without headache and who have no history of pubertal blocker. |
Clinical testosterone therapy No research interventions will be used as a part of the study since the research is observational. Testosterone treatment will be prescribed and followed by participant's clinical physician. |
