What are the red blood streaks on the testicles?

With the continuous improvement of living standards in real society, many men tend to neglect their physical health due to busy work. In the long run, it will easily lead to some physical diseases. The testicle refers to a part of the male reproductive system, and testicular diseases are very harmful to the health of the body. The appearance of red blood on the testicles is also a relatively common disease, which may be a phenomenon caused by the veins.

What are the red blood streaks on the testicles?

1. Anatomical factors:

1. The internal spermatic vein is long and enters the renal vein at a right angle, so blood flow is subject to a certain resistance. The left internal spermatic vein near the left renal vein has no valve, so blood can easily flow back.

2. Under normal conditions, the muscular fibrous tissue in the spermatic cord capsule can produce a pumping effect to promote venous return. When the above muscular fibrous tissue atrophies or relaxes, it is not conducive to venous return, causing varicocele.

Second: Physiological factors: The sexual function of young people is more vigorous, and the blood supply to the scrotal contents is abundant. Therefore, some varicocele may gradually disappear with age. In addition, standing for a long time and increasing abdominal pressure are also factors that cause the disease.

3. Other factors such as retroperitoneal lesions and hydronephrosis compress the internal spermatic vein and can cause symptomatic or secondary varicocele. The primary varicocele disappears quickly when lying down, while the secondary varicocele often does not disappear or disappears very slowly.

1. Some patients with varicocele will feel discomfort in the scrotum and other parts of the body, mainly manifested as a swollen feeling of the scrotum and testicles, a damp and cold scrotum, bloating, and dull pain. The uncomfortable feeling often radiates to the perineum, groin, and waist on the same side, seriously affecting the patient's normal life.

2. A small number of people may also experience emotional instability, mental depression, and even sexual dysfunction such as decreased libido, decreased sexual pleasure, pain during intercourse, erectile dysfunction and premature ejaculation.

3. Affecting male fertility, severe cases can cause testicular atrophy. The reason is that the temperature in the scrotum on the affected side rises and reflects to the opposite side, causing spermatogonia to degenerate, atrophy, and reduce the number of sperm; or because the hydroxytryptamine or steroids secreted by the left adrenal gland flow back into the testicle through the left spermatic vein, causing a decrease in sperm count.

Ectopic testicles

When the testicles descend from the inguinal canal, they may not descend into their normal position in the scrotum, causing ectopic testicles. Ectopic testicles are rare, and their clinical significance and treatment principles are generally the same as those of occult testicles. If the diagnosis is clear, surgical treatment should generally be considered, because androgen therapy is generally ineffective. Orchiopexy as early as possible before puberty can usually restore normal testicular function.

No testis

Congenital bilateral agenesis (absent testicles) is extremely rare, with only 61 cases reported in the literature. The cause may be that after the fetus has differentiated into different sexes, the fetal testicles are destroyed by some toxin. Treatment methods include: (1) Replacement therapy: Testosterone propionate is used from puberty, injected intramuscularly three times a week until the external genitalia develop normally; thereafter, the dose can be reduced to 10 mg, three times a week: or methyltestosterone 16-45 mg/day is taken orally (sublingually). (2) Surgical therapy: Implantation of a pseudotesticle in the scrotum (silicone rubber or silicone in a silicone capsule, the latter is better) to reduce the patient's "body image" and psychological disorders. Recently, a case of a successful testicular transplantation in a patient with arrhythmia was reported, with the testicles being taken from his twin brother.

Polytestis

It refers to the number of testicles exceeding 2. This disease was first confirmed in 1670. It is generally believed that there are no more than 3 testicles, with more on the left side than on the right side. Extra testicles rarely develop normally. Testicles that exist ectopically and atrophy for a long time may become malignant. Therefore, extra testicles should be surgically removed as soon as possible.

Paretic

It refers to the fusion of the two testicles, which can occur in the scrotum or in the abdominal cavity. Few testicles can survive due to other serious congenital malformations.

Orchitis is usually caused by bacteria and viruses. The testicles themselves rarely have bacterial infections. Since the testicles have a rich supply of blood and lymph, they have a strong resistance to bacterial infections. Bacterial orchitis is mostly caused by inflammation of the adjacent epididymis, so it is also called epididymo-orchitis. Common pathogens are Staphylococcus, Streptococcus, Escherichia coli, etc. Viruses can directly invade the testicles, the most common of which is the mumps virus. This pathogen mainly invades the parotid glands of children and causes "big mouth" disease. However, this virus also likes to invade the testicles, so viral orchitis often occurs shortly after the onset of mumps.

Testicular dysgenesis

This disease can be caused by blood supply disorders during the embryonic period or spermatic cord torsion during testicular descent. Cryptorchidism, sexual immaturity and hypopituitarism are also common causes of this disease. Patients with unilateral testicular dysplasia do not need treatment because of compensatory hyperplasia of the contralateral testis, while patients with cryptorchidism should undergo surgical treatment as soon as possible.
