The epididymis is the site where spermatozoa are matured and stored. After orchidectomy, this tissue loses up to 80% of its weight. In the prostate, androgen withdrawal by orchidectomy is associated with apoptotic cell death. The objective of the present study was to investigate whether apoptotic cell death is involved in the androgen-dependent weight loss found in the rat epididymis after orch...

unilateral orchidectomy (uo) is required when further breeding potential is important. it is sometimes necessary to remove a single testis in a matured stallion for therapeutic reasons. in this study, twelve donkeys were used to evaluate three techniques of unilateral castration, histological and morphological changes on the remaining testis. results of the study showed that each of the surgica...

The aim of the present study was to evaluate the effects of orchidectomy and subsequent chronic androgen administration on aortic media in male rabbits. Fifteen adult male rabbits were divided into orchidectomized (Orx), sham-operated controls (SO) and orchidectomized treated with testosterone dipropionate (Orx-TP). In all three groups, the mean area fraction of collagen in the outer half of th...

This study analyzes whether the release of nitric oxide (NO) and thromboxane A2 (TXA2) depends on the time lapsed since gonadal function is lost, and their correlation with the proliferation of vascular smooth muscle cells (VSMC) mediated by the epidermal growth factor receptor (EGFR). For this purpose, aortic and mesenteric artery segments from control and 6-weeks or 5-months orchidectomized r...

Submit Manuscript | http://medcraveonline.com reduced [3]. The reduction in fertility is documented in patients following orchidectomy with a contralateral viable testicle. In this case the contralateral testicle was atrophic following previous misdiagnosed torsion. Patients with severe testicular atrophy have undergone successful microdissection of sperm, in one study up to 56% of patients wit...

INTRODUCTION Testicular torsion may be an important cause of male infertility. We aimed to investigate the late hormonal function in patients with testicular ischemia/reperfusion injury of the testis after orchidectomy or detorsion. METHODS Twenty patients (mean age, 13.6 years) were prospectively evaluated at a mean of 5 years after testicular torsion. The serum follicle-stimulating hormone,...

Leydig cell tumors are rare and represent 1% to 3% of all tumors of the testis. Leydig cell tumors affect males at any age, but there are 2 peak periods of incidence: between 5 and 10 years and between 25 and 35 years. Their main clinical presentation is a testicular mass associated with endocrinal manifestations that are variable according to age and appearance of the tumor. Our patient, a 17-...
