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...
Germ cell degeneration in the contralateral testis of the guinea pig with unilateral torsion of the spermatic cord. Quantitative and ultrastructural studies
testis torsion quantitation germ cell guinea pig reproduction
2009/2/23
This study evaluated the long term effects of unilateral torsion of the spermatic cord on the contralateral testis of guinea pigs, employing both fine structural and quantitative studies. Young, adu...
Stagnation of blood in the microvasculature of the affected and contralateral testes of men with short-term torsion of the spermatic cord
Testis germ cells microvasculature electron microscopy torsion
2009/2/23
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...
Acute experimental testicular torsion
Acute experimental testicular torsion contralateral testis
2009/2/20
Other investigators have shown that chronic unilateral testicular torsion produces negative effects on the contralateral testis in experimental animals. In the present study, bilateral testicular we...
The effect of prepubertal spermatic cord torsion on subsequent fertility in rats
spermatic cord torsion fertility rat testis
2009/2/20
This study was undertaken to determine the effects of various durations of testicular torsion in prepubertal rats on their subsequent fertility, and to determine whether these effects could be alter...
Experimental Unilateral Torsion of the Spermatic Cord in Guinea Pigs
spermatogenesis testis guinea pig torsion
2009/2/19
A systematic investigation of the effects of unilateral torsion of the spermatic cord on the contralateral testis of the guinea pig was carried out for variable time periods, ie, seven days, one, ...
Endocrine and exocrine effects of testicular torsion in the prepubertal and adult rat
testicular torsion prepubertal adult rat
2009/2/13
Previous studies of experimental torsion have suggested that there may be important differences between the adult testis and the prepubertal testis in their responses to torsion, especially with reg...
Leydig cell function after experimental testicular torsion despite loss of spermatogenesis
Testis torsion ischemia rat Leydig cells testosterone
2009/2/13
Little is known about specific testicular cell responses to periods of testicular torsion. In particular, the steroidogenic capacity of Leydig cells in the post-torsion testis is unknown. Male Spr...
Spermatic cord torsion. Contralateral testicular degeneration at various ages in the rat
Testicular damage fertility rat
2009/2/6
Unilateral spermatic cord torsion causes damage to the contralateral testis in humans and animals models. It is now known, however, at what age an animal's reproductive capacity is most susceptible ...
Spermatic cord torsion: effects of cyclosporine and prednisone on fertility and the contralateral testis in the rat
spermatic cord torsion immunosuppression testicular damage
2009/2/6
Unilateral spermatic cord torsion results in contralateral degeneration and reduced fertility in the prepubertal male rat. This study was conducted to investigate the use of immunosuppression with c...
Late Hormonal Levels, Semen Parameters, and Presence of Antisperm Antibodies in Patients Treated for Testicular Torsion
Infertility function testis
2008/12/24
In spite of prompt diagnosis and either orchiectomy or preservation of the affected testis, infertility remains a significant sequel to testicular torsion. The objective of this study was to e...
Testicular Torsion Alters the Presence of Specific Proteins in the Mouse Testis as Well as the Phosphorylation Status of Specific Proteins
Oxidative stress testicular proteins
2008/12/23
Testicular torsion followed by torsion repair induces an ischemia-reperfusion injury to the testis that can render the testis aspermatogenic. Previous results have demonstrated this loss of sp...
Peptide and Nonpeptide Reactive Oxygen Scavengers Provide Partial Rescue of the Testis After Torsion
Apoptosis ischemia-reperfusion oxygen radicals
2008/12/3
Ischemia-reperfusion (IR) of the testis results in germ cell-specific apoptosis, followed by a reduction in testis weight and daily sperm production (DSP). This has been associated with an increas...
