Introduction
Blood in semen after sexual intercourse may be caused by factors such as excessive sexual activity, prolonged abstinence, urethral injury, seminal vesiculitis, or prostatitis. It may be accompanied by mild lower abdominal discomfort or a burning sensation in the urethra. In daily life, men should develop good living habits, avoid excessive sexual activity, and engage in appropriate exercise such as jogging or hiking, which benefits overall health.

Under normal circumstances, blood in semen after sexual intercourse may be caused by excessive sexual activity, prolonged abstinence, urethral injury, seminal vesiculitis, prostatitis, or other factors. It is recommended to visit a hospital to determine the exact cause and follow medical advice for treatment. Specific analysis is as follows:

1. Excessive sexual activity: Frequent sexual intercourse or masturbation may lead to local congestion in the reproductive system, resulting in blood appearing in the semen. This may be accompanied by mild lower abdominal discomfort or a burning sensation in the urethra. It is recommended to reduce the frequency of sexual activity and allow adequate rest for the reproductive system.

2. Prolonged abstinence: After a long period of sexual abstinence, heightened libido may lead to overly vigorous sexual activity, which can result in blood in the semen. It is advisable to adjust the frequency of sexual activity and avoid prolonged abstinence.

3. Urethral injury: During intercourse, improper positions or excessive intensity may cause mechanical injury to the urethra, leading to bleeding that mixes with semen. Symptoms may include pain at the urethral opening or difficulty urinating. Patients should take medications such as cefixime capsules, levofloxacin hydrochloride capsules, or amoxicillin capsules under a doctor's guidance to aid recovery.

4. Seminal vesiculitis: Inflammation of the seminal vesicle lining releases inflammatory factors that damage blood vessel walls, causing bleeding. Blood then mixes with semen and is expelled after intercourse. Symptoms may include perineal discomfort or pain during ejaculation. Patients are advised to take medications such as cefdinir dispersible tablets, diclofenac sodium sustained-release tablets, or azithromycin capsules under medical supervision to relieve symptoms.

5. Prostatitis: Inflammatory reactions in the prostate gland increase local vascular permeability, making bleeding more likely; blood may then be expelled along with semen after intercourse. Other possible symptoms include frequent urination, urgency, and urinary pain. Patients should take medications such as ciprofloxacin hydrochloride tablets, Sanjin tablets, or Qianlieshu capsules under a doctor’s recommendation to support recovery.

In daily life, men should develop healthy habits, avoid excessive sexual activity, and engage in moderate exercise such as jogging or hiking, which benefits overall health.
