This awkward moment I’m about to tell you happened in Biology class way back in Secondary School, the most beautiful girl in class (by some people’s beauty yardstick o not mine) asked me a very strange question. She asked if guys have a bone in their penis that makes it erect, I remember telling her no because I was sure I had no bone in mine. That question was asked by a curious 13 or 14 year old girl then but come to think of it, many girls reading this still assume a guy has a bone in his dick that makes it stand erect when aroused, so where does the bone disappear to when his dick is not erect?..lol
Not ashamed to say this but I know more about a woman’s private part than I know mine, most of what I wrote in my last post titled “Understanding HER private part” was from my head but most of what is in this piece is from google (in my own understanding tho..lol).
Before I proceed to the main gist, there is something I discovered about the penis that shocked me to my spinal cord which is the fact that the order for seminal ejaculation comes from the spinal cord and not from the brain which means its not the brain that tells the penis when to cum, its the spinal cord that gives that order (jeeeeeez my Biology teacher nobi sabi book sef..lol).
Alright now that is out of the way, let’s proceed.
The penis has two main functions which are:
1. Urination: Releasing urine from the bladder.
2. Ejaculation: releasing sperm and seminal fluid from the prostrate gland.
Above is the anatomy of the penis, let’s look at the organs one after the other.
The bladder is simply where urine is stored before release via the urethra.
The seminal vesicle as I just recently discovered produces a sugar-rich fluid (fructose) that mixes with sperm providing it with a source of energy and also helps with the sperms’ motility (ability to move) towards the egg. This fluid also has clotting properties that make the semen sticky. This ensures the semen clings inside the vagina for enough time for the sperm to travel to the egg.
The prostate gland also contributes additional fluid to the ejaculate and helps nourish the sperm.
The cowper’s glands produce a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.
The epididymis is a long, coiled tube that rests on the backside of each testicle. It functions in the transport and storage of the sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization.
The urethra is the tube that carries urine from the bladder to outside of the body. In males, it has the additional function of expelling (ejaculating) semen when the man reaches orgasm. When the penis is erect during sex, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.
The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra in preparation for ejaculation.
The scrotum is the loose pouch-like sac of skin that hangs behind the penis. It contains the testicles (also called testes), as well as many nerves and blood vessels. The scrotum has a protective function and acts as a climate control system for the testes. For normal sperm development, the testes must be at a temperature slightly cooler than the body temperature. Special muscles in the wall of the scrotum allow it to contract and relax, moving the testicles closer to the body for warmth and protection or farther away from the body to cool the temperature.
The testes are oval organs about the size of very large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for generating sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
When normal erection occurs, the sides and the bottom of the penis, the corpora cavernosum and the corpus spongiosum, respectively, become engorged with blood so that the penis enlarges, hardens, and assumes an erect position. Arteries bring blood into these two tubes, and veins carry blood away from them. The penis can be either limp or erect, depending on the flow of blood. In a non-erect state, the arteries that transport blood into the corpora cavernosum are somewhat constricted, while the veins that drain the blood from the penis are open. There is no way for pressure to build inside the penis. In this state, the penis is limp. When a man becomes aroused, the arteries leading into the penis open up so that pressurized blood can enter the penis quickly. The veins leaving the penis constrict. Pressurized blood is trapped in the corpora cavernosum, and this blood causes the penis to elongate and stiffen. The penis is erect.
I always saw the female private part as a complicated entity but after doing my research on the penis, it seems even more complicated. I hope you have learnt something as I have.
