The injections are given into a muscle every one to two weeks. Some long-acting testosterone formulations can be administered as injections every 10 weeks. Testosterone has a range of effects on the male body. This review attempts to determine, based on published studies, the temporal evolution of the effects induced by testosterone replacement therapy from its first manifestation until maximum effects are reached.
It should be noted that almost none of the studies cited were specifically designed to evaluate the temporal evolution of the effects. Some studies measure the effects of testosterone only after 3 months (3) and, in particular, the effects on libido and erections have occurred long before this time period (14, 6). We have observed significant differences in the onset of the effects of testosterone. The effects on libido and other psychological variables and the effects on the vasculature occur quite rapidly.
It is quite possible that these effects are not mediated by the classic androgen receptor, but by other mechanisms, such as effects on membranes (6,. In addition, the effects on erection occur quite rapidly and can be explained in part by non-genomic effects on the vascular erectile tissue of the penis (8). The injections are given with an interval of 2 to 10 weeks. They are inexpensive compared to other treatments.
However, the injections may not provide consistent benefits. Your testosterone levels will drop again between doses. Are you considering testosterone therapy to help you feel younger and stronger as you age? Know the risks before making a decision. A relatively small number of men experience the immediate side effects of testosterone supplementation, such as acne, breathing disorders while sleeping (worsening of sleep apnea), breast swelling or tenderness, or swelling in the ankles. Doctors also monitor high red blood cell counts, which may increase the risk of blood clots.
