How is the vas deferens malformation?
Vasectomy can be divided into congenital absence, communication with ureter and repeated vasectomy. If there are no other malformations, just a simple absence of vas deferens, the patient's sexual desire and sexual function are normal, and the only symptom is infertility. The clinical manifestation is azoospermia, but the serum hormone level is normal, which can be confirmed by testicular biopsy. If possible, surgical treatment is feasible, and the vas deferens stump is anastomosed with epididymis. The role of vas deferens is as important as that of women's fallopian tubes. If the vas deferens is abnormal, it will affect sperm and cause male infertility. Vasospermia is rare, mainly including ectopic, deletion, hypoplasia, repeated vas deferens and so on. However, epididymis, seminal vesicle, ejaculatory duct and vas deferens also originate from the mesonephric duct, so the abnormality of epididymis and seminal vesicle is often accompanied by the abnormality of vas deferens. Absence of vas deferens, such as absence of vas deferens, is more common. According to statistics, 1% ~ 10% of azoospermia patients have absence of vas deferens. Unilateral or bilateral deletion is usually accompanied by hypoplasia or deletion of epididymis, and complete deletion of seminal vesicle, ejaculatory duct, ureter and even bladder triangle may also occur, but the absence of vas deferens does not necessarily mean the absence of testis, because the two embryos come from different sources. Dysplasia of vas deferens: The vas deferens exists but is stunted, all or part of them are slender or imperforate. Its pathological manifestations are severe fibrosis and atypical hyperplasia of tissue structure, which are often found by patients with infertility. Ectopic vas deferens has one or two ectopic vas deferens, which are deviated from spermatic cord or have abnormal openings, and may also be complicated with other genitourinary malformations. Repeated vas deferens is rare and asymptomatic in clinic. Most of them occur after sterilization, and they are only discovered when they recall the reasons for repeated pregnancy. Therefore, male sterilization must be carefully examined. If there are patients with this disease, they should be ligated separately. Congenital bilateral vas deferens are generally infertile. The patient's physical development and bilateral testicles are normal, and there is no abnormality in sexual life, ejaculation and semen volume. The special reproductive plastic surgery department of Wuhan Shi Ming Urology Hospital has a top-class ultra-clean operating room, which is operated by authoritative urology experts, equipped with a full set of minimally invasive surgical equipment and Korean reproductive plastic surgery technology. It can perform painless and minimally invasive reproductive plastic surgery such as circumcision, penis lengthening, penis thickening, local spermatic vein resection and cryptorchidism, without bleeding or stitches, and the postoperative recovery is fast. Shaping the perfect shape of reproductive organs is the first choice for men.
