We present a case of a 27-year-old man with a history of weight loss. A chest x-ray demonstrated hilar lymphadenopathy and he was treated with anti tuberculosis treatment. He noticed a painless left scrotal swelling and a scrotal ultrasound scan raised the possibility of testicular cancer. He underwent an orchidectomy and histology confirmed a testicular sarcoidosis. He was commenced on steroid...

This study investigated the effects of oral administration of nicotine on body and reproductive organ weight, serum testosterone level and testicular histology in adult male rats. Forty male rats divided into five groups and treated for a period of 30 days with 0.5mg/kg (low dose) and 1.0 mg/kg (high dose) body weight of nicotine while the control rats received 0.2 ml/kg normal saline. The four...

The aim of this study was to determine whether the reproductive seasonality of local male goats from subtropical Mexico (26 degrees N) is controlled by photoperiod. The control group (n = 7) remained in an open shed under natural daylight. The two experimental groups (n = 6 each) were placed in light-proof buildings and exposed for 2 years (yr) to alternations of 3 months (mo) of long days and ...

The Japanese quail is a very valuable animal model for research in a variety of biological disciplines. The purpose of this study was to characterize and interrelate age-dependent testicular parameters with various blood constituents: blood glucose, plasma proteins and packed cell volume that are developing concurrently in the growing bird. Another objective of the study was to identify selecti...

The effects of Trypanosoma brucei infection on testicular morphology and function and the changes associated with treatment of infected dogs with diminazene aceturate were studied using fifteen Nigerian adult male dogs. The dogs were randomly assigned into three groups A, B and C consisting of five dogs each. Groups A and B were infected with 1 × 10(6) trypanosomes and group C was the uninfecte...

background:   objective: present study was conducted to observe the effects of testosterone, nandrolone, and stanozolol (forms of aas) intake during onset of puberty on the rat testicular histology.   materials and methods: juvenile male sprague-dawley (sd) rats (n=42) were divided into seven groups and were injected subcutaneously with medium dose of polyethylene glycol-200 (peg-200) (control)...

Tetramethylthiuram disulphide (Thiram), a dithiocarbamate fungicide was administered to male rats through gavage at dose 5, 10 and 25 mg/kg/day for 30, 60 and 90 days. A significant increase in relative testes weight (GSI) was observed at dose (25 mg/kg/d) after 90 days exposure, associated with mild pathomorphological changes. This included degeneration of seminiferous tubules with sloughing o...

Aim: To explore the potential role of Punica granatum ethanolic extract (PGEE) in Cyclophosphamide (CP) induced testicular toxicity. Methods: Healthy male Wistar rats were allotted to 4 groups (N=6, each) Group I: Control, Group II: CP 15mg/kg twice a week, Group III: PGEE 100mg/kg, Group IV: CP and PGEE for 28 days. At the end of the treatment period, organ weight, body weight, epididymal sper...

Background: Gibberellic acids are naturally occurring plant hormones that are used in agriculture as plant regulators and enter animals and human cells through diet. This study was undertaken to investigate effects of gibberellic acid on testicular tissue of adult rats. Materials and Methods: Twenty seven adult male Wistar rats after a one week acclimatization period were randomly divided into ...
