In 2003, an Institute of Medicine panel concluded that there was insufficient evidence supporting the benefits of testosterone in older men and recommended further research. Consequently, in 2010, the National Institute of Aging, which is part of the NIH, launched the Testosterone Trials (T Trials) to figure out whether testosterone can help with symptoms associated with low levels of testosterone secondary to older age (i.e., symptomatic hypogonadism).
If testosterone deficiency occurs during fetal development, then male characteristics may not completely develop. If testosterone deficiency occurs during puberty, a boy’s growth may slow and no growth spurt will be seen. The child may have reduced development of pubic hair, growth of the penis and testes, and deepening of the voice. Around the time of puberty, boys with too little testosterone may also have less than normal strength and endurance, and their arms and legs may continue to grow out of proportion with the rest of their body.

Most testosterone boosters were compiled with ingredients that were coming from the mouth of a bro scientist, so to speak. These ingredients had no real evidence to back their effects on testosterone production.
Some of these signs and symptoms can be caused by various underlying factors, including medication side effects, obstructive sleep apnea, thyroid problems, diabetes and depression. It's also possible that these conditions may be the cause of low testosterone levels, and treatment of these problems may cause testosterone levels to rise. A blood test is the only way to diagnose a low testosterone level.
