BACKGROUND Although risk estimates for synchronous and metachronous contralateral testicular cancers vary widely, many clinicians recommend routine biopsy of the contralateral testis for patients diagnosed with unilateral testicular cancer. We evaluated the risk of contralateral testicular cancer and survival in a large population-based cohort of men diagnosed with testicular cancer before age ...

Little is known about the efficacy and the factors affecting the outcome of fine needle aspiration biopsy of the testis for sperm retrieval in azoospermic men with defective spermatogenesis. A prospective study was designed to compare the efficacy of needle and open (window) testicular biopsies for testicular epididymal sperm extraction (TESE) in 35 consecutive men with azoospermia due to defec...

In December 1999, when the EU Commission issued the Strategy on Endocrine Disruptors 1 , researchers had already recorded impacts on wildlife in polluted areas throughout the world (e.g. reproductive and immune problems in Baltic seals). Links were being drawn to human diseases and disorders, such as testicular, breast and prostate cancers, decline in sperm counts, reproductive organ deformitie...

A young man with a low risk history for sexually transmitted diseases presented with an apparently longstanding, previously asymptomatic scrotal mass, highly suggestive of testicular malignancy on palpation. Ultrasound sited the lesion in the epididymis. Although there was no evidence of urethritis, chlamydia polymerase chain reaction testing was positive. Tumour markers were negative. Complete...

nigella sativa (black seed) is an important medicinal herb with folkloric use in wide range of diseases. it is well studied for its biological activities. however, there is limited information regarding its effect on the male reproductive system. this study describes the effect of the aqueous extract of n. sativa (nse) on testicular steroidogenesis from mice leydig cells in vitro . mice testicu...

Buffalo are an economically important source for meat and milk production, especially in Brazil. However, important aspects of their biology remain unknown thus far. Herein, we describe the reproductive characteristics of male Murrah buffalo (Bubalus bubalis) raised under extensive management conditions by applying biometrics associated with testicular weight. We analyzed seven males, divided i...

The objective of this study was to determine the appropriate non-linear function describing growth of some testicular traits (testicular length, testicular diameter, scrotal circumference and scrotal length) in Norduz male lambs. Testicular characteristics at 90, 110, 130, 150, 170, and 190 days of age for all the lambs were measured. Four growth (Monomolecular, Logistic, Gompertz, and Richard’...

background : as recently some reported is investigated about relation between cold weather and testicular torsion (tt), so we decided to evaluate this hypothesis risk factor for testicular torsion in our children’s hospital. objectives : the aim of this study is to evaluate the relation between cold weather and testicular torsion in children. methods: from january 2011 todecember 2015 totally h...
