Definition: Spermoscopy is a 4/4.5 Fr thick slim examination endoscope, which is one of the latest international medical treatment techniques for difficult male diseases such as non-ejaculation, hematospermia, low ejaculation volume, azoospermia, oligozoospermia, infertility, etc. It is especially effective in cases of persistent hematospermia, dilated ejaculatory ducts and seminal vesicles caused by sperm duct obstruction, azoospermia or oligospermia, and prolonged vesiculitis. Clinical value: In recent years, the overall sperm quality of men has shown a declining trend due to the effects of food and natural environmental pollution, adverse cultural erosion, work-life stress, uncontrolled arousal and sexual life, estrogen and antibiotics, and carcinogenic factors. According to a complete survey, one out of every 10 couples in China suffers from infertility. Azoospermia, oligospermia, hematospermia, male dysfunction and male cloacal tract lesions are the most common types of diseases that cause male infertility in clinical practice. The spermoscopy technique is undoubtedly the best treatment option for the aforementioned diseases. Sperm duct obstruction is one of the common causes in male infertility patients. With the development of seminoscopic technology, sperm duct obstruction, especially ejaculatory duct obstruction, is receiving more and more clinical attention. Holmium laser technology can relieve ejaculatory duct obstruction, restore the normal ejaculatory process and the quality and quantity of ejaculate, help sexual partners conceive, and at the same time increase the confidence in sexual life of such patients. Hemospermia is a common male disorder. In the past, most cases were difficult to define the cause and were considered idiopathic hemospermia. The reason for this is that the ejaculate is blood-colored due to a lesion in one part of the cloaca, such as an injury, inflammation, stone or tumor, or a systemic bleeding disorder, which is medically called “hematosperm”. Usually, people seldom pay attention to the color of semen, and even if they find hemorrhagic semen, they often mistakenly think it is due to female vaginal bleeding. The rapid development of modern medical imaging technology has made it possible to clarify the cause of many cases of hematospermia. Even if the cause is clear, effective treatment is often lacking clinically, and anti-inflammatory and other methods are often used, with mostly unsatisfactory results. Spermoscopy can be performed through the opening of the urethra seminalis, along the ejaculatory duct into the seminal vesicles, retrograde examination of the seminal vesicles and ejaculatory duct, and simultaneous lumpectoscopic treatment if lesions are found. If a tumor is found, it can be removed; if it is a stone, it can be removed after holmium laser lithotripsy under seminoscopy; inflammatory changes can be treated by giving thermal cautery to the inflamed mucosa under the microscope and flushing the accumulated infected seminal plasma or hemorrhagic mixture. After the above treatment, it is important to drink a small amount of water several times, and most importantly, to have a regular sex life after the operation, with seminal discharge every 3-7 days. The purpose is to “expel the infectious and bleeding mixture” and to promote the recovery of the function of the spermatic tract, to “push out the new, promote local microcirculation, increase local immunity, etc. The advantages of spermoscopy are “simple, convenient, effective and inexpensive”, easy to operate, direct observation, positive effect, less trauma, less pain, quick recovery, hospitalization cycle of about 3 days, etc. It has become a diagnostic and therapeutic procedure such as “non-ejaculation, hematospermia, oligospermia, chronic cloacal tract infection or stone, cyst, etc. It has become a new medical technology for the diagnosis and treatment of ejaculation, hematospermia, oligospermia, chronic cloacal tract infection or stone, cyst, etc.
