What is the cause of testicular deformity? Does testicular malformation affect fertility

Testis is an important male reproductive organ, and it also has a direct impact on male fertility. Testicular malformation is a rare disease, but in clinical infertility patients, what is the cause of testicular malformation, and what is the conventional treatment method?

How is testicular deformity?

At the 6th week of the embryo, the mesonephron and paranephron tubes formed, which became the reproductive tract of men and women. After the embryonic gonad differentiates into testis and produces testosterone, the renal tube gradually becomes the male reproductive tube under the action of androgen. The head of the mesonephric tube becomes the appendix of the testis, the testicular output tube derived from the mesonephric tubule and the testicular tube formed by the growth and winding of the lower mesonephric tube form the head of the testis, and the other testicular tubes form the body and tail of the testis.

The etiology of congenital epididymis malformation is still unclear. Because many testicular patients have testicular malformations, their occurrence may be related to endocrine dysfunction during embryonic development. Low testosterone level, undeveloped or undeveloped mesonephric tubules and mesonephric tubules, resulting in various testicular abnormalities. If the mesonephric duct is completely underdeveloped, the congenital testis and vas deferens will be insufficient. If the development stops at a certain part, that part will be closed. When the testicular tube is bent and twisted, the testicle is significantly prolonged, and the growth loop testicular malformation occurs.

How to treat testicular deformity?

When epididymis deformity does not affect fertility, no treatment is needed. Segmental testicular atresia can be treated with testicular vasectomy. Under the operation microscope with an enlargement of 10-20 times, the two methods of the testicular vas deferens, Silber and Wagenknecht, were selected. The main difference between the two methods is that the expanded testicular duct and the vas deferens end of the Silber method are the same, while the expanded testicular duct and the vas deferens end of the Wagenknecht method are the same. Cut the expanded testicular tube, first accept the fluid flowing from the broken end of the testicular tube to look for sperm. After confirming the existence of sperm, use 11-0 non-destructive nylon thread to align the testicular tube with the vas deferens mucosa. Generally, suture 4-6 stitches intermittently, and then 9-0 non-destructive nylon thread to align the epididymis membrane with the vas deferens muscle layer.

Epididymal head cyst can be treated by puncture and injection of sclerosing agent, but due to high recurrence rate and safe and reliable operation method, it is rarely used at present. The patients with testicular insufficiency cannot be treated by themselves, mainly to solve fertility problems. When the testicular spermatogenesis function of the patients is normal, they can be assisted with reproductive treatment. If testicular deformity is accompanied by testicles, the testicles must be fixed immediately.
