After the domestic Jin Baixiang et al. (1983), after a biopsy and normal testicles, they found that in the light mirror and electron microscope, they found that the patients with cryptor tests had fibrosis around the age of 2 to 4 years old., Formation of sand -like tumors caused by degenerative curvy sperm tube; the number of spermatogenesis cells in the sperm tubes from the age of 2 to 3 has decreased, and the degeneration has become prominent, and the lesions are involved in interstitial, spermatogenic cells, and sertoli.Cells and Leydig cells; more obvious at the age of 5 and worsen with age.Therefore, surgery should be performed after the age of 2, and the most appropriate age should be 2 to 4 years old.
Infertility is often concurrently concurrent. Because the temperature of the testicular of the testicles of bilateral cillowers increases by 1.5 ° C to 2 ° C than the temperature of the scrotum, and the increase in temperature can shrink the testicular epithelium and hinder the occurrence of sperm.Therefore, the hidden test of the merging infertility is caused by the environment of the testicles, and the higher the position of the crypto test, the more serious the testicular tissue changes.
In 1979, JOB reported that unilateral testes from the second year after life, testicles on the opposite side of normal positions also have a damage effect, that is, the so -called "sympathetic testicular disease".Bilateral testicular dysplasia.Or the antibodies and body fluid factors produced by hidden testicles affect the normal testicles, cause damage sensitively, and cause infertility.
Testosicle development is a type of poor genital development. Testeosidal development is relatively rare. Teste developmental dysplasia includes cryptorchidal test, multi -test, testless, testicular dysplasia, etc.Essence
1. The lack of testicular no testicles is very rare. The cause of the disease may be suppressed by toxins during the embryo, or the occlusion of the blood vessels, or the testes atrophy caused by trauma.Unilateral tests are mostly on the right and are often accompanied by the opposite cryptophage.Due to the lack of interstitial cells that secrete male hormones, bilateral -sides often lead to poor gender and combined tests.Testless people may have ectopic intervas cells.The establishment of diagnosis is mainly to identify with cryptor test, especially those with bilateral sides.Both sides are also lacking in general functional function, and cryptor tests can still maintain male sexual function.
2. Multi -test multi -test deformity is extremely rare in congenital bad.In 1670, BLASNS was first discovered in the autopsy and confirmed by pathology. The current literature reports less than 60 cases.Generally does not exceed 3 testicles, and the left side is more than the right.Foreign literature has reported 5 testicles patients.Multi -test deformities are considered to be the result of the division of the epithelial cell group in the reproductive cymbal.
3. Teste development of testicular development can cause testicular dysplasia due to blood supply disorders during the embryonic period due to blood supply disorder or reversing during testicular decline.Cisencular test is also a reason for testicular dysfunction.
4. The testicular fusion of both sides of the test system is extremely rare.It can occur in the scrotum or in the abdominal cavity.Tests are often accompanied by other serious congenital malformations, and there are very few adults.
5. When the testicular testis is 6 months to 7 months, the peritoneum is descended into the scrotum from the peritoneum.Testes or testicles have not dropped.
