The penis is the male sexual organ.
The shaft is the longest part of it. The head or glans is at the end of the shaft. The opening at the tip of the head, where urine and semen come out, is called the meatus.
Inside, two cylinder-shaped chambers called the corpora cavernosa run the length of the penis. They have a maze of blood vessels, tissue, and open pockets.
The urethra, the tube that urine and semen flow through, runs along the underside of them, in the spongy tissue of the corpus spongiosum.
Two main arteries (one in each of the corpora cavernosa) and several veins move blood in and out. Nerves relay messages to and from other parts of your body.
What Is an Erection?
An erection starts in your brain. Something you saw, felt, smelled, heard, or thought makes your nerves send chemical messages to the blood vessels in your penis. The arteries relax and open up to let more blood flow in; at the same time, the veins close up. Once blood is in the penis, pressure traps it within the corpora cavernosa. Your penis expands and holds the erection.
When the inflow of blood stops and the veins open, your penis becomes soft.
What Is Ejaculation?
When you’re aroused, tubes called the vas deferens squeeze sperm from the testes toward the back of the urethra. The seminal vesicles also release fluid there.
The urethra senses the sperm and fluid mixture. Then, at the height of sexual excitement, it sends signals to your spinal cord, which in turn sends signals to the muscles at the base of your penis. These contract powerfully and quickly, every 0.8 seconds. This forces the semen out of the penis as you climax.
HOW OFTEN SHOULD A MAN RELEASE SPERM??
For most men, ejaculating is synonymous with having an orgasm, although some men can have an orgasm without ejaculating.
Ejaculate contains fluid from the prostate, seminal vesicles, and bulbourethral glands. Though it contains a wide variety of substances Trusted Source, including citric acid, cholesterol, mucus, and water, its primary job is to deliver sperm.
Research shows that the frequency with which a man ejaculates may affect his health, sperm count, and overall well-being.
While no evidence says that not ejaculating causes serious health problems, frequent ejaculation may reduce a man’s risk of prostate cancer. Having satisfying sex with a partner may also improve a man’s health.
3 Stages of Men Ejaculation:
It starts with sexual arousal, which involves blood flowing into and getting store in the penis (an erection). During stimulation and intercourse, the body enters a phase known as “plateau”, which refers to the stage in which the body prepares to orgasm. Muscle tension intensifies and heart rate increases.
Semen is sent towards the top of the penis, also known as the urethra. And, finally, expelled from the urethra while penile muscles contract rapidly.
During this stage, signals of pleasure are also sent towards the person’s brain by the same nerves that cause the penile muscles to contract during an orgasm.
Once a man has reached orgasm and successfully ejaculated, his erection starts to go away. Muscle tension decreases and can experience a feeling of relaxation. Some men also feel drowsy directly after reaching orgasm, which accompanies the relaxed state.
The third, and final stage, of an ejaculation, starts here, referred to as the Recovery phase. But also commonly known as the Refractory period.
The refractory period can last for as little as 30 minutes. But some men find that their recovery phase lasts for much longer than half an hour.
A man is usually unable to achieve an erection during their refractory period and has to wait for this phase to pass before they can participate in a sexual activity again.
Conclusion
Being knowledgeable about the male reproductive system should be an important part of a man’s life. This will help him better understand himself and may even be of assistance when any sexual problems start to develop.
