Symptoms of vas deferens injury

summary

Vas deferens is the direct continuation of epididymal duct, about 50 cm long, with thick wall, developed muscular layer and small lumen. When touching in vivo, it is round and solid. The vas deferens has a long journey, starting from the end of epididymis, ascending along the posterior edge of testis and entering spermatic cord. In the spermatic cord, located in other components of the posteromedial, this segment of the vas deferens location is shallow, vasectomy is often performed in this part. Symptoms of vas deferens injury? Let's talk about it

Symptoms of vas deferens injury

Abnormal palpation of the epididymis or vas deferens, such as nodules, thickening, beaded changes or absence of the vas deferens or epididymis, is a symptom of abnormal infertility of the seminal canal. Congenital obstruction refers to congenital epididymal hypoplasia, congenital dysplasia or absence of vas deferens; Congenital atresia of vas deferens; Congenital ejaculatory duct obstruction can cause congenital seminal duct obstruction, which is a symptom of abnormal infertility.

Testicular morphology is normal or slightly reduced, and the texture is basically normal. The development of the secondary sexual characteristics is basically normal, but long-term obstruction, adverse factors stimulation will lead to testicular spermatogenesis blocked, if the epididymal gonadal abnormalities will lead to testicular diminution, is also a symptom of abnormal infertility.

Men with a history of azoospermia or low sperm count, infertility, diminished or insensible orgasm, ejaculation pain or weakness, reproductive system infection, surgery and injury need to be vigilant and have a clear semen examination. This is a symptom of abnormal infertility in the seminal canal.

matters needing attention

Ejaculatory orifice occlusion is one of the causes of obstructive azoospermia. The causes include congenital dysplasia and acquired disease factors, such as gonorrhea, nonspecific urethritis and other inflammatory adhesions, or prostate cysts, giant prostatic vesicles compression ejaculatory orifice. Patients with azoospermia, severe oligozoospermia and asthenospermia should be suspected of ejaculatory duct obstruction if they have at least one obvious vas deferens, less semen and no or low fructose in semen. If the serum FSH is normal and the spermatogenic cells of testicular biopsy are normal, the diagnosis can be made by vasography.
