Normal semen is milky white or milky yellow. If the semen is pink, red or brownish red, or if there is blood in the semen, it is called hematosperm. This syndrome is mainly caused by damp heat or deficiency fire in the lower jiao that disturbs the seminal chamber, injures the blood channels, and forces the blood to travel; occasionally, it may be caused by deficiency of the spleen and kidneys, qi does not take in blood, and the blood is not fixed; it may also be caused by overwork or trauma to the perineum that directly injures the blood channels. This syndrome is mostly seen in the western medicine of vesiculitis. 2, yin deficiency fire vigorous intercourse, yin essence damage; or heat evil injury yin; or over serving warm dry tonic yang products, damage the true yin; yin deficiency fire vigorous, false fire disturbs the seminal chamber, damage the blood complex, hair for blood essence. 3, spleen and kidney deficiency overwork or hunger and satiety damage the spleen. Insufficient Qi, lack of chemical sources, then Qi and Blood deficiency. Blood deficiency leads to essence deficiency, and essence deficiency leads to kidney deficiency. If the spleen is deficient in blood intake, and the kidney is deficient in sealing, the essence and blood will go down together and become blood essence. 4, trauma and damage to the lobe, too much force during intercourse, or too long damage to the blood lobe of the sperm chamber; or fall and injury, the sperm chamber or blood lobe of the sperm channel is damaged; the lobe is broken and the blood overflows, resulting in the development of blood sperm. The patient has pain in the perineum, groin and lower abdomen, and there is obvious pain when the penis is erect or during ejaculation; it can be accompanied by urinary frequency, urinary urgency, painful urination, blood in urine, difficulty in urination, and other symptoms of urinary tract infection; the swollen, curved and swollen tube can be palpated on rectal examination in the upper prostate, and the pain to touch is obvious.
