The Reproductive System in Men

In male patients, the reproductive system consists of several organs, some of which, unlike those belonging to a similar system in women, are external organs, which means they are not inside the body.

External Organs

There are three external parts of the system under discussion, namely:

  • Penis. Men use this organ to perform an intercourse. Attached with its root to the body, namely the abdomen wall, penis has the shaft and the head (or the glans), the latter being the most sensitive area of the penis. When a male person achieves orgasm, the fluid, which consists of semen combined with sperm, is ejaculated through an orifice found at the penis’s tip. Source:
  • Scrotum. This skin formation features a form of a small pouch or a sac below the shaft of the penis. Its destination is to hold and protect testicles as well as create thermo-stabilized environment around them. The latter is a vital condition for sperm viability.
  • Testicles. Two testicles, which are oval-shaped structures, are hidden inside the scrotum. The organs are responsible for production of the male-specific hormone, testosterone, and sperm.

Internal Organs

Along with external parts, the purpose of which can be easily recognized, the body system under discussion also involves a number of internal ones. Some of them to mention are:

  • The prostate gland. This important organ is about a tennis ball size. Just above it, the urinary bladder is found. The gland produces a fluid, which is necessary to transport spermatozoids and provide them with nutrition. Urethra, which is a kind of canal to conduct the ejaculate, passes through the structure.
  • Epididymis. This part has a form of a long coil-shaped tube sitting behind each of the testicles. Its major function is to transport and hold until maturity spermatozoids produced by the testicles.
  • Urethra. This is another tube-like structure, which conducts both urine and sperm to the opening at the head tip. When the erection occurs during sex, blocking the urine flow is triggered so that nothing but semen can move along.
  • Seminal vesicles. These are pouch-like structures, whose purpose is to produce a fluid. The latter, being rich in sugar, serves as a source of energy sperm cells use to move forward. Actually, this fluid contributes the most to the male ejaculate volume.

Major Functions

All those organs constituting the male reproductive system are to perform several important functions such as:

  • Sperm and semen production, maintenance and transportation. Sperm is a specific fluid, which is to contain reproductive cells, while semen is a liquid carrier medium, the purpose of which is to deliver and protect sperm.
  • Sperm discharging inside the female vagina during sex.
  • Production of sex hormones specific for men, which determine the condition and performance of this function in men.

The reproductive system is highly dependent on hormone levels in the male body. There are two male-specific hormones involved, namely testosterone as well as the luteinizing hormone. The former determines how virile body characteristics are developed in a person, while the latter is the follicle-stimulating hormone responsible for the process known as spermatogenesis (i. e. sperm production).
