精索靜脈曲張 男性不育禍首Varicocele culprit for male infertility

精索靜脈曲張 男性不育禍首 【中新網】一提起精索靜脈曲張，很多人不是很熟悉。其實，在男子的陰囊裏，左右兩邊各有一條由輸精管、動脈、靜脈血管等組成的條索狀組織，醫學上稱之為精索，精索裏面的靜脈就叫做精索靜脈。由於解剖結構上的特點，以及男性生理發育等諸因素，精索靜脈血管容易淤血擴張，形成蚯蚓狀的靜脈團，這就叫做精索靜脈曲張。精索靜脈曲張是男性常見的泌尿疾病，一般年輕男性約10%有此症狀。 瀋陽日報報導，精索靜脈曲張分三度，輕度時局部觸及不到曲張的靜脈，只是患者感覺不適；中度時，患者站立時可以觸及曲張的靜脈，但外表看不到；重度時，陰囊部可以看到曲張的靜脈呈蚯蚓狀、團狀。 由於精索靜脈曲張也是男性不育的主因，約有三成不育的患者都是患上了精索靜脈曲張。精索靜脈曲張時，約有50%～80%的患者精液檢查不正常，表現為精子數少，活動度低，形態不正常。 精索靜脈曲張引起不育的原因有：精索靜脈曲張時由於精索靜脈內血液淤滯，可以引起陰囊內溫度增高，睪丸溫度可升高1℃～2℃，溫度持續長期增高，可影響睪丸產生精子，導致無精子症和少精子症；同時附睪的高溫環境也不利於精子的成熟。 另外，長時間坐沙發等軟椅也容易引起精索靜脈曲張，進而影響生育。人類本來的坐姿，是以坐骨的兩個結節作為支撐點的，這時陰囊輕鬆地懸掛於兩大腿之間，然而坐在沙發或其他軟椅上時，原來的支點下沉，整個臀部陷入沙發中，沙發的填充物和表面用料就會包圍，壓迫陰囊，當陰囊受到壓迫時，靜脈回流不暢，睪丸附近的血管變粗，淤血嚴重時就會導致精索靜脈曲張，患者會出現睪丸下墜沉重，下腹鈍痛等症狀。這時，由於血液淤滯，精索靜脈內壓力增高，氧和營養物質缺乏，影響代謝產物的清除，從而影響精子發生和成熟。 精索靜脈曲張該怎麼治療呢？醫生說，輕度的可以保守治療，即通過休息，穿緊身內褲，減少劇烈運動，適當的使用活血藥物等來治療，而中、重度的或伴有不育或精液異常的，是必須做手術的。 因為精索靜脈曲張，使血液回流受阻，造成睪丸的血液循環障礙，使睪丸的生精和分泌功能不能正常進行，久之可以導致睪丸的萎縮，喪失所有功能。 醫生表示，這種手術並不複雜，只需要半個小時就可以完成，不僅沒有痛苦，患者兩三天就可以出院。尤其青少年出現這樣的症狀，更要及時手術治療，以免引起生殖器官發育不良。 2008-09-29 Varicocele culprit for male infertility 【】 BEIJING, filed a varicocele, a lot of people are not very familiar with. In fact, the man in the scrotum, or so on each side by a vas deferens, artery, vein, and other components of the cord-like organization, called the medical spermatic cord, spermatic vein on the inside called the spermatic cord vein. As the structural characteristics of the anatomy, physiology, as well as men, and other development factors, spermatic vein congestion easy expansion to form a worm-like vein of Mission, which is called varicocele. Varicocele is a common male urinary tract diseases, generally young men by about 10% of the symptoms. Shenyang Daily reported varicocele is divided into three degrees, slightly less than when the local touch of varicose veins, but the patients feel sick; moderate, standing in patients with varicose veins can be touched, but the outside can not see; severe, Department of the scrotum can see the varicose vein was earthworm-shaped, like college. As the varicocele is the main cause of male infertility, about 30 percent of infertility patients are suffering from a varicocele. Varicocele, about 50% to 80% of patients with abnormal semen examination, the sperm showed less activity is low, irregular shape. Varicocele infertility caused by a number of factors: varicocele because of spermatic vein blood stasis, the temperature inside the scrotum can cause increased testicular temperature could rise 1 ℃ ~ 2 ℃, the long-term sustained increase in temperature can affect the testicles Produce sperm, resulting in azoospermia and oligospermia; testosterone at the same time attached to the high-temperature environment is not conducive to sperm maturation. In addition, for a long time, such as Ruan Yi Zuo Shafa also easily lead to varicocele, which affect fertility. Human beings have the sitting is the ischium two nodules as a strong point, this time in the scrotum easily fly between the two legs, but sitting on the sofa or other soft chair, the original point of sinking into a sofa as a whole hip , The sofa and filler material to be used as the surface will be surrounded by the scrotum of oppression, when the scrotum have been long oppressed, the poor venous return, the testicular blood vessels in the vicinity of Biancu, serious congestion will lead to varicocele, there will be patients with testicular A heavy fall, the dull pain in the lower abdomen, and other symptoms. At this time, due to blood stasis, spermatic vein pressure increased, the lack of oxygen and nutrients, the impact of the removal of metabolites in order to influence the occurrence and mature sperm. Varicocele how the treatment of this? The doctor said that the mild to conservative treatment, that is, through the rest, wearing tight underwear and reduce strenuous exercise, proper use of drugs for the treatment of promoting blood circulation, and, accompanied by severe or infertility or abnormal sperm, it is necessary surgery The. Because varicocele, the blood returning blocked, resulting in the testicular blood circulation obstacles to the testicular germ and secretion can not be normal, for a long time can lead to the atrophy of the testicles, loss of all functions. Doctors said that this surgery is not complicated, just half an hour to complete, not only pain, the patient can be discharged from hospital two or three days. In particular, young people have such symptoms, but also surgery in a timely manner, so as not to cause genital dysplasia. 2008-09-29 View more information, see the World Journal reported that e-ePaper
