In terms of complexity, the male reproductive system is in no way close to that of the female reproductive system. Nevertheless, it is complex all the same in a way that it has both an internal and external part. The external part is likely the most commonly known as this is where penis, testicles, and scrotum are located – the three of which are popularly known for their use or exposure during sexual intercourse and they are also the three main parts of the external male reproductive system. Of course the penis itself is also made up of three parts, namely the head, shaft, and the root.
When it comes to the internal male reproductive system, it mostly involves accessory organs than the actual sexual organ itself. The list below shows the internal parts:
1. Bulbourethral Glands – also known as Cowper’s glandes, these are very small glands which roughly the size of peas and are situated on the sides of the urethra, just beneath the prostate area. The bulbourethral glands secrete a clear and slippery fluid which is ducted directly towards the urethra. The main purpose of the production of this fluid is the lubrication and neutralization of any acidity present in the urethra brought about by urine and occasional residual droplets.
2. Ejaculatory Ducts – these ducts are made from the joining of the seminal vesicles and the vas deferens and ducts directly towards the urethra.
3. Prostate Gland – this gland may be likened to the size of a walnut and is situated underneath the urinary bladder as well as the frontal part of the rectum. The prostate secretes additional fluid for ejaculation and also helps in the nourishment of the sperm. The urethra, which is basically a tube-like ducting, passes ejaculate through the center of the prostate gland which is then expelled during climax.
4. Seminal Vesicle – these are shaped like pouches and are attached towards the vas deferens and situated just near the base of bladder. The seminal vesicle provides the basic nourishment for the sperm and provides it with the energy that it needs to help it become motile. Most of the fluid emitted during ejaculation is composed of the fluid made from the seminal vesicle.
5. Urethra – this is basically a tube which carries not just urine from the urinary bladder, but also semen from ejaculation. Despite it being only one tube in carrying both urine and semen, the two fluids never gets mixed together. This is because semen is only ejected when the penis is erect and that urine is only ejected from it when the penis is limp. If you are male, you may have noticed that sometimes during the morning when you need to urinate that you are having difficult urinating and trying to bend your penis downward from its morning erections just so you could urinate.
6. Vas Deferens – the vas deferens is a muscular tube coming from the epididymis towards the pelvic cavity. Its main purpose is the transportation of sperm towards the urethra for possible ejaculation.
