Sex Hormones and Voice: From Puberty to Gender-Affirming Therapy
Thursday 6th August 2026, 5:00 PM - 7:00 PM (London Time)
How do sex hormones define the human voice?
This course offers a comprehensive exploration of the vocal apparatus as a hormone-sensitive organ, analysing the physiological changes occurring at puberty as well as the changes induced by gender-affirming hormones initiated during adolescence.
The session begins by decoding the sexual dimorphism of the voice. While prepubertal voices remain largely similar, the surge of sex steroids at puberty drives dramatic physiological changes, resulting in clearly distinguishable male and female vocal characteristics. We will analyse how endogenous sex steroids—androgens, oestrogens, and progesterone—act on laryngeal tissues to drive these changes.
For adolescents experiencing gender incongruence, these changes can be a source of intense distress. In transgender and gender diverse people, the experienced gender does not align with the sex at birth. This incongruence often leads to significant distress, that it is referred to as gender dysphoria. Medical interventions aim to alleviate this distress by aligning physical characteristics, including the voice, with an individual's experienced gender. This course presents cutting-edge research on the long-term effects of Gender-Affirming Hormone Therapy (GAHT) initiated during adolescence. We will examine the clinical pathway from Gonadal Hormone Suppression (GHS) to the subsequent administration of exogenous testosterone or oestrogens.
Results from the analysis of a cohort of transgender men and women evaluated 5 to 10 years after starting treatment will be discussed. By comparing their vocal outcomes to cisgender men and women of the same age range, we will explore the changes induced by the treatment on voice fundamental frequency, intensity, and quality. Moreover, we will discuss how early start of GHS can help improving vocal outcomes, and the synergistic impact of voice training and gender-affirming vocal surgeries.
