"Testosterone has been reported to play a role in the frequency of nonerotic or reflex erections, including nocturnal penile erections and for the production of seminal fluid. There is no literature on the role of testosterone on nocturnal emission at any age. It seems reasonable to speculate that as testosterone is involved in causing nocturnal erections and production of seminal fluid, testosterone may also cause increases in nocturnal emission. It seems possible that nocturnal emissions may be induced/facilitated by factors other than hormones that prime the adolescent for this physiological response, as not all boys experienced nocturnal emission but all boys did receive testosterone."
