DEPO-Testosterone Injection, for intramuscular injection, contains testosterone cypionate which is the oil-soluble 17 (beta)- cyclopentylpropionate ester of the androgenic hormone testosterone. Testosterone cypionate is a white or creamy white crystalline powder, odorless or nearly so and stable in air. It is insoluble in water, freely soluble in alcohol, chloroform, dioxane, ether, and soluble in vegetable oils.
DEPO-Testosterone Injection is indicated for replacement therapy in the male in conditions associated with symptoms of deficiency or absence of endogenous testosterone.
1. Primary hypogonadism (congenital or acquired)-testicular failure due to cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome; or orchidectomy.
2. Hypogonadotropic hypogonadism (congenital or acquired)-idiopathic gonadotropin or LHRH deficiency, or pituitary-hypothalamic injury from tumors, trauma, or radiation.

TRADE-Testosterone Replacement and Dutasteride Effectiveness [Completed]
The purpose of this research study is to determine whether the combination of the male
hormone testosterone [T] in gel form and the oral drug dutasteride [D], used to shrink large
prostate glands can safely reduce the size of the prostate gland and symptoms of prostate
enlargement (called benign prostatic hyperplasia [BPH]) compared to T treatment alone in men
with low testosterone (called hypogonadism).

Anabolic and Inflammatory Responses to Short-Term Testosterone Administration in Older Men [Recruiting]
Skeletal muscle loss is a common consequence of aging and in some individuals reaches a
level that compromises health and quality of life. Age-associated increases in cytokine and
inflammatory signaling may be important contributors to this process. In this project the
investigators will test the hypotheses that 1) testosterone will inhibit cytokine and
inflammatory signaling in skeletal muscles of older adults and 2) will augment the anabolic
response to increased skeletal muscle activity. The investigators will also assess the
practical question of whether testosterone injection and gel application elicit similar
responses. Resistance exercise will be used as a means of stimulating both inflammatory and
anabolic responses in skeletal muscle. In order to assess the effects of testosterone on
these responses, fourteen subjects will perform resistance exercise on two occasions
separated by 7 days. The first session will be performed prior to the initiation of
testosterone therapy and the second session will be performed after receiving testosterone
for 7 days.
