Testosterone Replacement Therapy (TRT)

What Is Testosterone?

It is the primary male hormone responsible for regulating sex differentiation, producing male sex characteristics, spermatogenesis and fertility. 3


    • Gonadotropin Releasing Hormone (GnRH) - released by the hypothalamus to stimulate the pituitary gland to secrete luteinizing hormone (LH) and follicular stimulating hormone (FSH)2
    • Luteinizing Hormone (LH) - released by the pituitary gland to stimulate the Leydig cells in the testes to produce testosterone2
    • Follicular Stimulating Hormone (FSH) - released by the pituitary gland and stimulates the Sertoli cells in the testes to produce sperm2

What Are The Symptoms of Low Testosterone?

Causes of Low Testosterone

Primary Hypogonadism is disease of the testes that results in the inability of the testes to produce testosterone. Some examples would be congenital abnormalities, infection, orchitis, radiation, trauma, medications and environmental toxins.3

Secondary Hypogonadism is disease of the pituitary or hypothalamus. Some examples would be congenital abnormalities, cancer, hemochromatosis, TBI, hyperprolactinemia, opiate use, sleep apnea, and chronic diseases such as obesity, diabetes, metabolic syndrome, etc.3

Adult-Onset Hypogonadism is a mixed type that is most commonly associated with aging.3

Treatment Options

Typically testosterone is replaced via injection into the subcutaneous or muscle tissue once or twice weekly, but creams can also be used as well for those that don't want to inject.
