We understand this may infuriate some members of society but we believe the need for honest reporting supersedes mismanaged anger and aggression.
Studies have shown that women trans women undergoing testosterone injections and transitioning to men experience increased rage and aggression. This has been known for years.
A previous study from Italy found trans men undergoing testosterone treatment experience varying aspects of aggressive behavior.
This may explain all the threats and beatings.
People undergoing female to male gender-affirming testosterone treatment are likely to experience increased aggression — which may be worse if their periods persist.
Creating characteristic male features in people who are transitioning requires testosterone. Increased testosterone has previously been linked to increased aggressive behavior, but has not been widely investigated in trans people.
To find out more, Giovanna Motta at the University of Turin, Italy, and her colleagues evaluated 52 transmen with an average age of 28, before and at least 7 months after they began receiving testosterone treatment.
Testosterone is given with the aim of achieving concentrations that lie within the physiological male range. This reduces secondary female characteristics — it shrinks the breasts and stops menstrual periods, for instance, while simultaneously increasing male features, such as deepening of the voice and altered muscle distribution.
The team assessed varying aspects of aggressive behavior in their participants, including how often angry feelings are experienced over time, who or what those angry feelings are expressed against, and how they are cooled or controlled.
During the 7-month testosterone treatment, anger expression and anger control both increased. Specifically, there was a significant change in the feelings of anger towards other persons or objects and towards themselves.
The authors of the study say it’s important to note, however, that despite the increase in anger expression, there were no reports of aggressive behavior, self-harm, or psychiatric hospitalization.
They suggest that the increase in anger control may be due to an improved ability to control angry feelings by calming down, possibly because the treatment itself produces greater self-confidence. Regular psychotherapy sessions that monitor the impact of hormonal treatments might also have prevented the onset of aggressive behavior.
Interestingly, participants whose menstrual bleeding continued despite hormone treatment were more likely to feel and express anger in an uncontrolled way compared with those who achieved amenorrhea – one or more missed periods.
