The human reproductive system is all about how the timing, hormones, male and female reproductive systems (sperm and egg). First, in order for a baby to come into this world, the male and the female reproductive systems must work correctly. Both male and female has their own/different parts that work in order for a baby to be conceived. Although the male and the female reproductive systems are different, once they meet and come together they work together to make a baby at the end of result.

The male’s reproductive system produces something called a sperm; a tadpole like cell. It is said that when a male is to ejaculate, there are about 40 million to 600 million sperms are released at that one time. In that 40 million to 600 million sperms only about 5 million to 20 million are fertile, and the rest are infertile. Epididymis is another part of the males’ reproductive system. This is where the sperms get its nutrients and grows to be mature. It’s made up of smooth muscle cells; tube that is 20 feet in length on the posterior or the back side of each testis which are tightly coiled. Ductus deferens, also called the vas deferens; it measures up to be about 14 inches (35 centimeters) in length to an average adult male. This is where the sperm is moved along their smooth muscular wall. Ejaculatory duct is a short passageway that was made up by the vas deferens and duct of seminal vesicles. This is where the ducts empty the sperm and fluid into a single urethra; its measurement is just less than 1 inch. Urethra is another part to the male reproductive system; the male urethra extends from the urinary bladder to the tip of the penis (measures up to 6 to 8 inches in distance). In the male urethra, it can serve as a reproductive and urinary system. It transports the sperm and urine out of the body. However, it will never release both the sperm and urine out of the body at the same time. When a sperm enters the urethra from the ejaculation, the muscles junction of the...
