分析精索静脉曲张患者睾丸及精液指标的变化，探讨其对于男性生殖功能的影响。方法回顾分析2003年以来在我院诊治的172例精索静脉曲张患者的资料，阴囊超声检测患者双侧睾丸的体积。收集167例患者的精液标本进行分析，同时收集163例青年健康志愿者的精液分析资料作为对照组。结果所有患者均存在左侧精索静脉曲张，其中63例为双侧精索静脉曲张，但大多数左侧精索静脉曲张的临床分级均高于右侧。患者左侧睾丸体积平均为...
The effects of nicotinic acid on testicular atrophy caused by di（2-ethylhexyl）phthalate（DEHP）and metal concentrations in the atrophic testes
di-(2-ethylhexyl) phthalate (DEHP) testicular atrophy testicular metal concentrations
2009/4/1
Di-(2-ethylhexyl) phthalate (DEHP) is the most common plasticizer for plastics such as polyvinyl chloride. However, recent studies have demonstrated toxic effects of DEHP on the testes and liver in ro...
Histopathology of prepubertal rat testes subjected to various durations of spermatic cord torsion
spermatic cord torsion rat
2009/2/23
Sixty prepubertal rats were subjected to unilateral spermatic cord torsion for a duration of 0, 1, 3, 5, 9 or 12 hours. At the end of this period, the ipsilateral testes either were removed for imme...

blood microcirculatory vessels men varicocele
2009/2/20
This study reports on the stagnation of blood within the microcirculatory vessels of the testes of patients with varicocele. Both fine structural and quantitative studies were carried out on testi...
Seminiferous tubule degeneration in human cryptorchid testes
Seminiferous tubule degeneration human cryptorchid testes
2009/2/20
Two types of degenerating seminiferous tubules were found in cryptorchid testes with Sertoli cell hyperplasia of children and adults: 1) tubules with central degeneration, and 2) tubules with total ...
Squash preparation studies of germ cells in human fetal testes
testis preleptotene germ cells chromosomes
2009/2/20
Testes from human fetuses 21 to 41 weeks of gestation were investigated using a modified squash technique. At all of the gestational ages examined, 90 to 95% of the germ cells were in interphase. Pr...

Ultrastructural lesions testes hyperprolactinemic men
2009/2/20
Testicular tissue from eight men with prolactinomas and elevated serum prolactin were evaluated by light (LM) and transmission electron microscopy (TEM). A semiquantitative assessment of testicular ...
