Although the involvement of viruses in alterations of testicular function and in sexually transmitted diseases is well known, paradoxically, the testicular antiviral defense system has virtually not been studied. The well known antiviral activity of interferons (IFNs) occurs via the action of several IFN-induced proteins, among which the 2'5' oligoadenylate synthetase (2'5' A synthetase), the d...
Testicular neoplasms occur in more than 90% of cases, due to primary testicular germ cell tumors. Other entities are non germ cell tumors of the testis, testicular manifestation of lymphomas or metastases. International and interdisciplinary co-operation has led to the development of urological guidelines and to good therapeutic success for testicular neoplasms. The gold standard for treatment ...
Testicular atrophy is a rare but distressing complication of inguinal hernia repair. Apart from the postsurgical etiology, ischemic orchitis and subsequent testicular atrophy may occur secondary to compression of the testicular vessels by chronically incarcerated hernias. We present a rare case of testicular atrophy secondary to a large long standing incarcerated inguinal hernia of 2-decade dur...
The effect of in-vitro culture on the motility and morphology of fresh and frozen-thawed human testicular spermatozoa obtained from obstructive azoospermic patients and on the motility of testicular spermatozoa obtained from non-obstructive azoospermic patients was evaluated. The outcome of intracytoplasmic sperm injection (ICSI) with fresh and frozen-thawed human testicular spermatozoa was stu...
AIMS To determine the role of polymerase chain reaction (PCR) based minimal residual disease (MRD) detection of leukaemia specific DNA in testicular relapse in childhood acute lymphoblastic leukaemia. METHODS DNA was obtained from archival testicular and bone marrow samples from boys with acute lymphoblastic leukaemia who relapsed in the testes. Overlapping DJH clone specific primers derived ...
Impaired testicular function, i.e., hypogonadism, can result from a primary testicular disorder (hypergonadotropic) or occur secondary to hypothalamic-pituitary dysfunction (hypogonadotropic). Hypogonadotropic hypogonadism can be congenital or acquired. Congenital hypogonadotropic hypogonadism is divided into anosmic hypogonadotropic hypogonadism (Kallmann syndrome) and congenital normosmic iso...
We present the case of a 77 year old man who presented with acute onset of left scrotal pain and swelling, interpreted as epididymo-orchitis, and treated twice, within four days with different antibiotics. On the third presentation an urgent Doppler ultrasound scan confirmed absent testicular blood flow on the affected side. Emergency scrotal exploration revealed a torted left spermatic cord, a...
A 46 year old tennis player was addressed to our clinic after incidental finding of right testicular calcification on plain x-ray of the spine. Urologic consultation revealed a hard non-tender testicular mass which required inguinal orchiectomy. Final histology revealed large cell calcifying Sertoli cell tumor: we herein present the case and review current physiopathology of such rare testicula...
Perinatal exposure to testosterone (T), which can act upon both the androgen receptor (AR) and, via aromatization of T into estrogens, upon estrogen receptors, organizes many adult behaviors in rodents. We compared behaviors in wild-type (WT) male rats and AR-deficient rats with the testicular feminization mutation (Tfm), which on the day of birth were either gonadectomized (Neo-Gdx) or sham op...
This study investigated the probable protective effects of resveratrol (RES), an antioxidant, against methotrexate- (MTX-) induced testis damage. Twenty-four male Sprague Dawley rats were randomly divided into four groups: control, RES, MTX, and MTX + RES groups. Rats were sacrificed at the end of the experiment. Plasma and tissue malondialdehyde (MDA) levels, superoxide dismutase (SOD) and cat...
