Testosterone

Testosterone Introduction

Testosterone is a sex hormone mainly found in males but present in both sexes. It is mainly produced in the testicles in men, and the ovaries in women. Testosterone is responsible for the development of male characteristics such as facial hair, increased muscle mass, and deeper voice. Additionally, it also plays a role in the development of healthy bones, reproductive organs, and the production of red blood cells.

Uses for Testosterone

Testosterone is used to treat men who have low testosterone levels due to certain medical conditions, such as a genetic disorder or an injury resulting in testicular failure. It is also used to treat certain types of breast cancer in women. Testosterone replacement therapy is sometimes used to treat certain conditions, such as the inability to get or maintain an erection.

Mechanism of Action

Testosterone works by stimulating certain receptors in the body. This stimulates the release of luteinizing hormone (LH), which in turn helps the testicles to produce and secrete testosterone into the bloodstream. Once in the bloodstream, testosterone helps to increase muscle mass, bone growth, and sexual desire.

How Long Does it Take to Work?

The effects of testosterone therapy vary from person to person. Generally, it takes several weeks before people start to feel the beneficial effects. During this time, testosterone levels in the blood need to be monitored to ensure that levels remain in the therapeutic range.

Absorption

Testosterone is most often administered as an intramuscular injection and absorbs into the bloodstream quite quickly. It is also available as a transdermal patch, gel, or cream, which is less effective than an injection but still increases testosterone levels.

Route of Elimination

Testosterone is eliminated from the body via urine and feces. It is primarily excreted in the form of glucuronic acid, with some being excreted as sulfates and other metabolites.

Dosage

Prior to initiating testosterone gel 1.62%, confirm the diagnosis of hypogonadism by ensuring that serum testosterone has been measured in the morning on at least two separate days and that these concentrations are below the normal range.

Starting dose of testosterone gel 1.62% is 40.5 mg of testosterone (2 pump actuations or a single 40.5 mg packet), applied topically once daily in the morning.

Apply to clean, dry, intact skin of the shoulders and upper arms. Do not apply testosterone gel 1.62% to any other parts of the body including the abdomen, genitals, chest, armpits (axillae), or knees.

Dose adjustment: testosterone gel 1.62% can be dose adjusted between a minimum of 20.25 mg of testosterone (1 pump actuation or a single 20.25 mg packet) and a maximum of 81 mg of testosterone (4 pump actuations or two 40.5 mg packets). The dose should be titrated based on the pre-dose morning serum testosterone concentration at approximately 14 days and 28 days after starting treatment or following dose adjustment. Additionally, serum testosterone concentration should be assessed periodically thereafter.

Patients should wash hands immediately with soap and water after applying testosterone gel 1.62% and cover the application site(s) with clothing after the gel has dried. Wash the application site thoroughly with soap and water prior to any situation where skin-to-skin contact of the application site with another person is anticipated.

The dosage of testosterone will vary depending on the individual’s health condition, age, and other factors. It is important to follow the prescription of the doctor to ensure proper dosing. The most common dosage for testosterone replacement therapy is 50-100 mg weekly.
