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...
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...
Bilateral testicular biopsies from four men with a short duration (3 hours 10 minutes to 4 hours 30 minutes) of unilateral spermatic cord torsion and testicular biopsies from six men with irreversib...
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...
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 ...
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...
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 ...
Isolated rat testes perfused in closed circuit with albuminated Krebs-Ringer bicarbonate buffer were examined by light and electron microscopic techniques in order to assess the structural integrity...
Hyperprolactinemia was induced in adult male golden hamsters by transplantation of four homologous pituitaries under the renal capsules. The resulting elevation of plasma prolactin (PRL) levels wa...
Low-molecular-weight peptides with inhibin activity have been isolated from sheep, human, rat, and chicken testes by simple gel filtration. These peptides, isolated from avian and mammalian specie...
We have previously reported that incubation of testicular slices with inhibin in the presence of 6 x 10-8 M oFSH resulted in a dose-related reduction in accumulation of cyclic AMP due to a decreas...
A 51-year-old man with previously diagnosed bilateral anorchia was shown by endocrine investigation of his hypophyseal-gonadal axis to have functioning testicular tissue. The implications of endocri...
The basis for cell-cell adhesion in the seminiferous epithelium of the developing testis is doubtless critical in supporting events that are essential for the onset and maintenance of normal sperm...
Spermatogenesis in Asian men appears to be more susceptible to suppression by steroidal contraceptives administered in clinical trials than spermatogenesis in Caucasian men. The objective of this ...
Relaxin is a 6-kd polypeptide that exerts important hormonal effects in many female mammals. Relaxin is produced by the ovary, placenta, or uterus in many mammalian species. The functions of relax...
