This image shows the male reproductive organs. The testis must reside outside of the body/abdomen because spermatozoa maturation requires a lower temperature than possible within the body. In order to achieve the proper testis temperature, there are 2 layers of muscles of the scrotum. The layer found in region H that wrinkles the integument of the scrotum is called the muscle and is involuntary muscle, whereas the fascicles found in region J form the muscle and are muscle from the abdominal wall. During the emission phase, spermatozoa are moved via peristalsis from the epididymis, shown as , into the ductus/Vas deferens. These paired tubes develop from the embryonic precursor called the . During the ejaculation phase (stimulated by the branch of the autonomic nervous system), the spermatozoa will reach the ejaculatory duct, shown as , where they will be mixed with fructose-rich fluid secreted by the before entering the prostatic urethra. If fertilization occurs, the new cell is called a and is in nature.
