What Is a Human penis?
Penis, the copulatory organ of the male of higher vertebrates that during mammals usually also gives the channel via which urine leaves the frame. The corresponding structure in lower invertebrates is often referred to as the cirrus.
The human penis is anatomically divided into two continuous regions—the body, or outside component, and the basis. The root of the penis starts off evolving immediately underneath the bulbourethral glands with a long cylindrical body of tissue called the corpus spongiosum (or corpus cavernosum urethrae). This tissue extends through the frame of the penis to the tip, in which it expands into a mushroom-formed structure called the glans penis. Running through the center of the corpus spongiosum is the urethra, a common passage for semen and urine; the urethra leads to a slitlike starting at the tip of the glans penis. Beginning alongside of the bulbourethral glands are a pair of lengthy cylindrical bodies known as the corpora cavernosa penis. These retain thru the body of the penis, occupying the sides and top element at once above the corpus spongiosum; they terminate right now before the glans penis.

The structure of the human penis in the male reproductive system
The penis is one of the external organs of the male reproductive device (used for sex and to conceive babies) and the urinary system (used to "pee"). It is positioned at the front of the body at the base of the pelvis. The scrotum, containing the testes (a.K.A. Testicles), is located just underneath the penis.
The penis consists of numerous foremost structures:
Glans: The glans, or head of the penis, is the sensitive structure at the cease of the corpus (shaft).
Urethra: The urethra is a tube in the penis that runs from the bladder to the pinnacle of the penis. It is used for urination. It additionally crosses via the prostate gland, wherein a gap (known as the ejaculatory duct) gets sperm and fluids that blend together to shape semen.
Meatus: The meatus is the outlet at the tip of the glans via which urine or semen exits the body.
Prepuce: The prepuce, or foreskin, is a loose fold of pores and skin that covers the head of the penis. The removal of the foreskin is called circumcision.
Corpus cavernosa: The corpus cavernosa are columns of spongy tissue that run along the interior shaft of the penis. When full of blood, the tissues stiffen, causing an erection.
Corpus spongiosum: The corpus spongiosum is the 1/3 column of tissue that forestalls the urethra from remaining in the course of an erection.
The penis is nicely furnished through blood vessels. The shaft, which incorporates the urethra and 3 columns of erectile tissue, is wrapped in a band of connective tissue known as the fascia and blanketed with pores and skin. The base of the penis is supported by means of connective tissues, referred to as suspensory ligaments, that keep the penis near the pelvic bone.
There is a huge variant in penis size, and the common flaccid ("smooth") length of a penis is 3.5 inches. The common length of an erect penis is 6 inches, with a mean circumference of five inches.

What is the role of the human penis in the male reproductive system?
The mainTrusted Source capabilities of the penis consist of sexual sex and micturition (urination).
When someone reports arousal, the penis fills with blood, causing an erection. As such, erectile features are closely associated with cardiovascular fitness.
The tension of the erection allows someone to penetrate a partner and feature sex. Following sexual interest or manual stimulation, a person can then ejaculate. After ejaculation or lack of arousal, the penis can go back to a flaccid kingdom.
The penis also plays a vital urinary role. The penis incorporates the urethra, which lets in passage of urine from the bladder to the urethral establishment, enabling a person to expel urine from the body.
The primary functions of the penis are urinary and sexual. The sexual function of the penis may be defined as two levels: erection and ejaculation.
Urination
Urination is the release of urine (pee) from the body. This happens while urine passes from the bladder via the urethra to the meatus. The urine is driven out of the body by means of the contraction of the detrusor muscle inside the wall of the bladder.
Between the penis and the bladder is the external sphincter muscle, which may be managed to hold in or launch urine.
Erection
An erection is the stiffening of the penis because of sexual arousal and/or bodily stimulation. It is also everyday for erections to arise during sleep and upon waking. An erection happens when there's an extended waft of blood into the corpus cavernosa and corpus spongiosum.
During an erection, arteries supplying the erectile tissues will dilate (widen), inflicting the penis to engorge (fill) with blood. The engorgement compresses the veins through which blood normally exits the penis. This "traps" the blood and allows sustaining the erection.
Ejaculation
Ejaculation is the release of semen from the penis. It is usually observed by means of a sexual response known as an orgasm.
Ejaculation includes a chain of simultaneous, involuntary muscle contractions:
First, a tube called the vas deferens contracts, propelling sperm from the testicles to the ejaculatory duct.
At the identical time, the prostate gland and seminal vesicles contract, adding fluids that make up maximum of the quantity of semen.
At the same time, fast contraction of muscle mass at the base of the penis, known as periurethral muscle mass, propels semen out of the penis.
What affects the health of the human penis in the male reproductive system
Erectile dysfunction: A guy's penis does no longer attain sufficient hardness for enjoyable sex. Atherosclerosis (damage to the arteries) is the maximum commonplace purpose of erectile dysfunction.
Priapism: An abnormal erection that doesn't go away after several hours even though stimulation has stopped. Serious troubles can result from this painful condition.
Hypospadias: A delivery illness in which the opening for urine is at the front (or underside), as opposed to the tip of the penis. Surgery can correct this condition.
Phimosis (paraphimosis): The foreskin cannot be retracted or if retracted cannot be lower back to its ordinary role over the penis head. In grownup men, this will arise after penis infections.
Balanitis: Inflammation of the glans penis, commonly because of infection. Pain, tenderness, and redness of the penis head are signs and symptoms.
Balanoposthitis: Balanitis that also includes the foreskin (in an uncircumcised man).
Chordee: A peculiar curvature of the quiver of the penis, gift from birth. Severe instances can also require surgical correction.
Peyronie’s Disease: An atypical curvature of the shaft of the penis may be caused by harm to the person penis or different medical conditions.
Urethritis: Inflammation or infection of the urethra, frequently inflicting ache with urination and penis discharge. Gonorrhea and chlamydia are commonplace causes.
Gonorrhea: The bacteria IN. Gonorrhea infects the penis at some stage in intercourse, causing urethritis. Most cases of gonorrhea in men are symptoms of painful urination or discharge.
Chlamydia: A bacteria that can infect the penis via intercourse, inflicting urethritis. Up to 40% of chlamydia instances in guys cause no signs and symptoms.
Syphilis: A bacteria transmitted throughout intercourse. The preliminary symptom of syphilis is often a painless ulcer (chancre) on the penis.
Herpes: The viruses HSV-1 and HSV-2 can motivate small blisters and ulcers at the penis that reoccur through the years.
Micropenis: An abnormally small penis, gift from start. A hormone imbalance is concerned in many instances of micropenis.
Penis warts: The human papillomavirus (HPV) can cause warts at the penis. HPV warts are tremendously contagious and spread throughout sexual contact.
Cancer of the penis: Penis most cancers may be very uncommon inside the U.S. Circumcision decreases the danger of penis cancer.
Maintaining the health of the human penis in the male reproductive system
It is beneficial for someone to often wash their penis using a slight soap. People ought to keep away from abrasive or closely scented products as they could irritate the penis. People also can use this time to check their penis for anything that appears unusual or exceptional. This can encompass checking the testicles for any lumps.
People ought to additionally recall using barrier strategies, which includes condoms, whilst having sexual intercourse, and undergo normal sexual health screenings, despite the fact that they may be in a monogamous relationship.
Other pointers can include popular recommendations to enhance ordinary fitness. This may additionally involve ingesting a healthful weight loss plan, getting normal exercising, restricting alcohol consumption, and seeking to avoid smoking.
What is the difference between the female reproductive system and the male reproductive system?
Recently, the subject of reproduction has been in the news a lot.From human fertility and preimplantation genetic diagnosis to stem cells, it seems like science is making great strides towards allowing infertile couples to have children of their own.However, there are many other areas of medicine that affect reproductive systems and they aren’t always as positive.In fact, many diseases can cause problems with sexual function or (in some cases) render people completely infertile. Here
The male and female reproductive systems are both necessary for sexual reproduction. The male reproductive system produces sperm, while the female reproductive system produces eggs. The sperm must fertilize an egg in order for pregnancy to occur. Both systems are made up of several different organs that work together to achieve this goal.
The male reproductive system and the female reproductive system are both very different in many ways. The female reproductive system is made up of many different parts, such as the ovaries, fallopian tubes, and the vagina, while the male reproductive system is made up of the testicles, seminal vesicles, and the penis. The ovaries produce the eggs that are fertilized by the sperm from the testicles, and the fertilized egg then implants itself in the lining of the uterus. The fallopian tubes transport the eggs from the ovaries to the uterus.
