METHODS: Seventy-four pubertal male Wistar rats were randomly selected. The experimental group consisted of 40 rats, divided into four subgroups, submitted to 1.080 degrees counterclockwise left testicular torsion and its scrotal fixation at the beginning of the experiment, and left orchiepididymectomy at one, five, ten and 90 days, respectively. The control group consisted of 24 rats, divided into four sham operation control subgroups. An additional control subgroup consisted of the ten remaining rats, submitted only to the left orchiepididymectomy at the beginning. At 90 days, the contralateral testes of the experimental and control subgroups were collected for the evaluation of their spermatogenesis parameters: testicular weight, seminiferous tubular diameter, Johnsen score and differential counting of the germ cells. RESULTS: No statistically significant differences were observed among the experimental and control subgroups for all of the spermatogenesis parameters of the contralateral testes. CONCLUSIONS: Testicular torsion does not cause long-term effects on the spermatogenesis of the contralateral testis in pubertal rats, and the orchiepididymectomy of the twisted testis is not necessary for preventive purposes for the contralateral spermatogenesis.<\/jats:p>","DOI":"10.1590\/s0102-86502012000600006","type":"journal-article","created":{"date-parts":[[2012,6,4]],"date-time":"2012-06-04T13:16:58Z","timestamp":1338815818000},"page":"388-395","source":"Crossref","is-referenced-by-count":17,"title":["Long-term effects of the testicular torsion on the spermatogenesis of the contralateral testis and the preventive value of the twisted testis orchiepididymectomy"],"prefix":"10.1590","volume":"27","author":[{"given":"Fernando","family":"Lorenzini","sequence":"first","affiliation":[{"name":"UFPR, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renato","family":"Tambara Filho","sequence":"additional","affiliation":[{"name":"UFPR, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Regina Paula Xavier","family":"Gomes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anderson Joel","family":"Martino-Andrade","sequence":"additional","affiliation":[{"name":"UFPR, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas Rolf","family":"Erdmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge Eduardo Fouto","family":"Matias","sequence":"additional","affiliation":[{"name":"UFPR, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","reference":[{"issue":"12","key":"ref1","first-page":"1167","article-title":"Testicular torsion and risk factors for orchiectomy","volume":"159","author":"Mansbach JM","year":"2005","journal-title":"Arch Pediatr Adolesc Med."},{"issue":"4","key":"ref2","doi-asserted-by":"crossref","first-page":"528","DOI":"10.2164\/jandrol.106.002097","article-title":"Late hormonal levels, semen parameters, and presence of antisperm antibodies in patients treated for testicular torsion","volume":"28","author":"Arap MA","year":"2007","journal-title":"J Androl."},{"issue":"3","key":"ref3","doi-asserted-by":"crossref","first-page":"210","DOI":"10.1016\/j.jpurol.2007.11.007","article-title":"Testicular torsion: orchiectomy or orchiopexy?","volume":"4","author":"Taskinen S","year":"2008","journal-title":"J Pediatr Urol."},{"issue":"10","key":"ref4","doi-asserted-by":"crossref","first-page":"988","DOI":"10.1002\/bjs.1800751015","article-title":"Testicular torsion in Bristol: a 25 year review","volume":"75","author":"Anderson JB","year":"1988","journal-title":"Br J Surg."},{"issue":"3","key":"ref5","doi-asserted-by":"crossref","first-page":"349","DOI":"10.1046\/j.1464-410x.2000.00106.x","article-title":"Torsion of the testis","volume":"86","author":"Cuckow PM","year":"2000","journal-title":"BJU Int."},{"issue":"6","key":"ref6","doi-asserted-by":"crossref","first-page":"661","DOI":"10.1007\/BF02552183","article-title":"Experimental testicular torsion and its effects on the contralateral testis","volume":"29","author":"Aydin S","year":"1997","journal-title":"Int Urol Nephrol."},{"issue":"2","key":"ref7","doi-asserted-by":"crossref","first-page":"790","DOI":"10.1016\/j.juro.2010.03.109","article-title":"Preventive effects of cyclosporine a combined with prednisolone and melatonin on contralateral testicular damage after ipsilateral torsion-detorsion in pubertal and adult rats","volume":"184","author":"Jeong SJ","year":"2010","journal-title":"J Urol."},{"issue":"1","key":"ref8","first-page":"137","article-title":"Protective effect of sildenafil citrate on contralateral testis injury after unilateral testicular torsion\/detorsion","volume":"66","author":"Yildiz H","year":"2011","journal-title":"Clinics (S\u00e3o Paulo)."},{"issue":"3","key":"ref9","doi-asserted-by":"crossref","first-page":"268","DOI":"10.1111\/j.1365-2605.2010.01077.x","article-title":"Protective effect of ischaemic post-conditioning on ipsilateral and contralateral testes after unilateral testicular ischaemia-reperfusion injury","volume":"34","author":"Shimizu S","year":"2011","journal-title":"Int J Androl."},{"issue":"1","key":"ref10","first-page":"65","article-title":"Acute experimental testicular torsion","volume":"6","author":"Turner TT","year":"1985","journal-title":"No effect on the contralateral testis.
