Endocrinologists managing gender-affirming hormone therapy (GAHT) must consider complex patient histories. This article details managing thromboembolic disease and low bone density in adults undergoing GAHT.
Area of Science:
- Endocrinology
- Gender-affirming care
- Hormone therapy
Background:
- Gender-affirming hormone therapy (GAHT) is increasingly initiated by endocrinologists for transgender and gender diverse (TGD) individuals.
- TGD patients often present with complex medical histories that require careful consideration during GAHT management.
- Shared decision-making between patients and providers is crucial for safe and effective GAHT.
Purpose of the Study:
- To outline management strategies for TGD adults with specific complex medical conditions undergoing GAHT.
- To provide guidance for endocrinologists encountering patients with thromboembolic disease or low bone mineral density during GAHT.
Main Methods:
- This article presents an Approach to the Patient, focusing on clinical considerations.
- Case examples of 2 adults with thromboembolic disease and 2 adults with low bone mineral density are discussed.
- Management considerations for both feminizing and masculinizing GAHT are explored.
Main Results:
- The study highlights the importance of individualized GAHT management based on patient comorbidities.
- Specific challenges and recommendations for managing thromboembolic disease in the context of GAHT are presented.
- Strategies for addressing low bone mineral density in TGD patients receiving GAHT are discussed.
Conclusions:
- Endocrinologists must integrate patient-specific medical histories into GAHT decision-making.
- Careful monitoring and management are essential for TGD patients with thromboembolic disease or low bone density on GAHT.
- Personalized approaches ensure the safety and efficacy of gender-affirming hormone therapy.

Hormonal Regulation
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...
Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
Major Hormones and Their Functions
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
