What is the reason for blood in semen? What is the reason for blood in stool?

Whether a man's semen is normal or not is closely related to the health of his reproductive system. For example, if many men's semen contains blood, it means that the man has certain andrological diseases. On the contrary, if the stool contains blood, it can also mean that the man has hemorrhoids, anal fissures, polyps or colorectal cancer. Below, we will introduce the reasons why men have blood in their stool and semen.

1. What causes blood in stool?

1. Hemorrhoids: Blood in stool is usually bright red, not mixed with stool but attached to the surface of stool; it can also appear as dripping blood before and after defecation, or in severe cases as spurting, which often occurs when the stool is constipated. To prevent hemorrhoids, you should develop the habit of defecating on time to prevent constipation. In addition, pelvic floor exercises are effective in improving local blood circulation, preventing and treating the development of hemorrhoids and rectal prolapse.

2. Anal fissure: The amount of blood in the stool is small, and most of it is found on toilet paper; defecation may be accompanied by severe anal pain, so that the patient dare not defecate. Anal fissure is caused by the cracking of the entire layer of the anal canal mucosa and the formation of acute and chronic ulcers. The key to preventing anal fissure is to solve constipation.

3. Polyps: There is no discomfort when having blood in the stool, the stool is normal, and the blood is often attached to the surface of the stool.

4. Colorectal cancer blood in the stool is characterized by persistent, chronic bloody stools mixed with mucus and feces, frequent urge to defecate, and sometimes only some blood or mucus without feces. About 80% of rectal cancers have blood in the stool, but the farther the cancer is from the anus, the lower the incidence of blood in the stool.

2. Causes of blood in semen

1. Inflammation

Reproductive system infection is the most common cause of hematospermia. Infection pathogens include viruses, bacteria, tuberculosis and parasites, etc. It can also be the result of trauma, urethral foreign bodies, and chemicals. Common ones include seminal vesiculitis, prostatitis, posterior urethritis, seminal vesicle tuberculosis, epididymal orchitis, etc. Stones in the prostate, seminal vesicle or vas deferens can also cause hematospermia.

2. Obstruction or cyst

Ejaculatory duct obstruction can cause the proximal end of the obstruction to dilate and swell, leading to rupture and bleeding of mucosal blood vessels. Common examples include seminal vesicle cysts, ejaculatory duct cysts, seminal vesicle diverticula, ejaculatory duct cysts, and prostate cysts.

3. Tumor

A variety of benign tumors of the urogenital tract can cause hematospermia, such as posterior urethral adenoma, leiomyoma, fibroma, adenomatous polyp and prostatic hyperplasia. Malignant tumors of the bladder, prostate, testicles and seminal vesicles can also cause hematospermia.

4. Vascular abnormalities

Varicose veins of the seminal vesicle, prostatic urethra, and bladder neck are the causes of hematospermia. In addition, vascular abnormalities in the reproductive system can cause hematospermia, including pelvic arteriovenous malformations, prostatic hemangiomas, seminal vesicle and spermatic cord hemangiomas, etc.

3. Prevention of blood in semen

Moderate sex life, not too frequent or intense, nor too long abstinence. Avoid drinking alcohol and spicy food, and do not ride long distances to avoid recurrence of the disease. Those who have given birth can take a warm water bath at 41°C to 42°C, once a day, for 15 to 20 minutes each time. For those who have not given birth, avoid taking a bath to avoid high temperatures affecting sperm quality.
