Teste biopsy is an important detection method for male infertility. Through testicular biopsy observation, the degree of sperm function of testicular sperm and sperm disorder can be directly estimated, and the ability of testicular synthetic steroid hormones.The choice and judgment prognosis of treatment is also an important basis.The following pathological changes can be seen in testicular biopsy:
(1) Normal testicular structure: The fine seizure tube before adolescence is small, no foundation membrane, only primitive germ cells and support cells, and the interstitial cells are not obvious.After adolescence, fine sperm tubes can be seen in tubular ejaculation epithelium. Spermocytes (sperm cells, sperm cells, sperm cells) and support cells at all levels have many sperm.EssenceThe reproductive pathological changes of the testicles mainly occur in the alpine essence of the sperm tube and the alfalfa.
(2) Low sperm function: Sperm existence is existed, but the ejaculation is thinner, and the number of spermatogenesis at all levels has decreased.
(3) Sperm stagnation: Sperm stagnation is stagnant at a certain cell stage, and sperm cannot be formed. It is more common in the stages of sperm cells, followed by sperm cell stage, less stagnant in the stagnation of sperm cells.
(4) Sperm cells fall off and arranged disorders: Undocious spermocytes and sperm cells, sperm cells, etc. fall off into the septic tubular lumen, block the lumen, and cannot discharge.It is often accompanied by disorders of sperm cell arrangement.
(5) Only support cell syndrome: only the cells are only supported by the cells, and the lack of any sophisticated cells.The diameter of the tube is reduced, the boundary film is thickened, and the quality is hyperplasia.This is a congenital abnormal, no sperm, no fertility, but the second sexual characteristics are normal.
(6) Mixed change: A variety of abnormalities can be seen in the fine sperm tubes, such as various types and degrees of spermatogenesis: stagnation of sperm stagnation, falling off disorders; hyperplasia of the boundary film or transparent -like degeneration.
(7) Unsure testicular: The testicular development status of adults still stops before adolescence. The diameter of the fine sperm tube is small, the lumen has not yet appeared, and there is no sperm production.
(8) The transparent degeneration of the sperm tubular tubes: fast development, presented, and manifested as the boundary film of the fine tubes, which is transparent, and expands to the lumen and interstitial.Accompanied by different degrees of spermatogenesis.In severe cases, various cells in small tubes have disappeared, and only the shadow of the fine tube is shrinking.
