What does a boy's penis look like?

Many people have heard of the phrase "differences between men and women". Men and women are not only different psychologically, but also have great differences in the physiological structure of the human body. Therefore, many female friends are very curious about some of the physiological structures of men. Some women are even curious about what the male reproductive organs look like. So, what does a boy's penis look like?

First, what does a boy's penis look like? As an important male sexual organ, it has the function of sexual intercourse, urination and ejaculation. The penis is mainly composed of two corpora cavernosa and one corpora cavernosa, which are covered with basic fascia and skin. It is divided into three parts: root, body and head. The back is the root of the penis, which is attached to the inferior ramus of the pubic bone, the sciatic ramus and the urogenital diaphragm; the middle is the corpus penis, which is cylindrical and hangs down in front of the pubic symphysis; the front is enlarged as the glans penis, and there is a sagittal cleft at the tip of the head called the external urethral orifice. There is a ring-shaped groove at the junction of the head and the body called the penis neck or coronal groove. The corpus cavernosum of the penis is a cylinder with two thin ends, one on the left and one on the right, located on the back of the penis. The left and right parts are tightly connected, extending forward, with the front end tapering and embedded in the depression on the bottom of the glans penis. The rear end of the corpus cavernosum is separated and called the crus penis, which is attached to the lower abdominal ramus and ischial ramus on both sides. The corpus cavernosum is located on the ventral side of the corpus cavernosum, and the urethra runs through its entire length. The middle part is cylindrical, with the front end bulging into the glans penis and the rear end bulging into the urethral bulb, located in the middle of the two crus penis and fixed to the fascia below the urogenital diaphragm.

Second, the blood supply to the penis comes from the dorsal penile artery, a branch of the external iliac artery. During sexual arousal, the three branches of the dorsal penile artery and its arterioles dilate, increasing blood flow; the arteriovenous communication branch is blocked, venous return decreases, and the cavernous sinus becomes congested, causing penile erection. The head of the penis has abundant nerve endings, so the frenulum of the penis, the coronary sulcus, and the area around the urethral opening are particularly sensitive to external mechanical stimulation. The afferent nerve of sensory sensation is the dorsal penile nerve. After reaching the low sexual response center of the sacral cord, the outgoing parasympathetic nerves innervate the penile vascular smooth muscle and change the vascular state. Pathological changes in the penile blood vessels and nerves can affect mating function.

What does a boy's penis look like? The male genitals are the male reproductive system, which is the organ for male reproduction. It consists of two parts: internal and external genitalia. The external genitalia include the scrotum and penis; the internal genitalia include the reproductive glands (testicles), sperm ducts (epididymis, vas deferens, ejaculatory ducts and urethra) and accessory glands, seminal vesicles, prostate and bulbourethral glands. The male genitals begin to develop during puberty, and have reproductive functions after they mature.
