The male reproductive system is a means for producing life. While the most males begin puberty at the age of twelve, they will not reach their sexual peak until their eighteen and can still produce healthy sperm until their late sixties. There are four main areas of the male reproductive system that I will be covering in this report. Furthermore, I will be covering the diseases that affect and can inhibit this system.
The testes are the gamete-reproducing organs of the male reproductive system. The testes (or gonads) begin their development on the abdominal cavity, right near the kidneys. Shortly after birth the testes descend through a inguinal canal and into the scrotum. Each testis is an oval structure about five centimeters long and roughly three centimeters in diameter. ( These are only averages and estimates, actual size may very a few millimeters.) Also each testis is surrounded by tough white fibrous connective tissue capsule, or referred to as the tunica albuginea.
This tunica albuginea surrounds each testis and extends inward to form a septa that partitions the testis into lobules. Within each lobule and between the semiferious tables are interstitial cells that produce sex hormones. There are about two hundred and fifty lobules in each testis. One of these sex hormones is testosterone that is produced by the testes (or it now is made synthetically). Testosterone is responsible for inducing and maintaining male secondary characters. Without testosterone, males would be unable to make sperm, and reproduction would be impossible.
The scrotum, which houses the testes, consists of subcutaneous tissue or "tissue from within" This tissue divides the scrotum into two parts. Each of these parts contain one gonad. Smooth muscle fibers, contained within subcutaneous tissue contract and expand to give the scrotum its wrinkled or relaxed appearance, these fiber...
