Body PartFunction TesticlesStore sperm and produce testosterone Vas DeferensMuscular tube that transports semen EpididymisThe set of coiled tubes connected to the Vas Deferens ScrotumHelps to regulate temperature in order to produce and store sperm Seminal Vesicles Produce a sugar-rich fluid (fructose) that provides sperm with a source of energy and helps with the sperms’ motility. The fluid of the seminal vesicles makes up most of the volume of a man’s ejaculatory fluid, or ejaculate. Prostate GlandContributes additional fluid to the ejaculate. Prostate fluids also help to nourish the sperm.

 An Erection starts in the brain, when a male is stimulated physically or mentally.  Brain then sends a chemical message to the nerves in the penis which tell the penile blood vessels to relax which allow blood flow into the penis. Once this happens the penis expands allowing an erection.  Erections go away on their own or after ejaculation.  Ejaculation is the release of semen at climax.  Males during adolescence may have a number of erections daily (even without stimulation)  Nocturnal emissions- happens during puberty at night when testosterone levels are high. A male will ejaculate during sleep. Males usually grow out of it after puberty.
