This alternate definition is more useful, however, since you can use it to relate lengths of arcs to angles. The length of an arc is is the radius r times the angle Î¸ where the angle is measured in radians. For instance, an arc of Î¸ = 0.3 radians in a circle of radius r = 4 has length 0.3 times 4, that is, 1.2.
About 17 percent of men treated for low T receive testosterone injections every 7 to 22 days. Testosterone levels peak two to three days after the injection and then slowly drop until the next dose of the hormone is given. There are also testosterone patches that men can use. These patches can be placed on areas of the body such as the back, stomach, upper arm, or thigh.
Testosterone replacement therapy (TRT) is the recommended treatment for male hypogonadism. It is normally given as a topical gel, transdermal patch, or by injection. Oral forms of testosterone are not used due to the high risk of side effects, such as upset stomach. TRT can eliminate many, if not all, of the signs and symptoms of male hypogonadism.
