introduction: cyclophosphamide (cp) is used for the treatment of various cancers. in spite of its therapeutic importance, a wide range of adverse effects such as reproductive toxicity has been observed following the administration of this drug in human and experimental animals. in the current study, we have investigated the adverse effects of cp on morphology and histology of testis rats. metho...

This research aims to study testis and epididymis of dry land goat (Capra hircus) on B-mode ultrasound imaging. Twelve adult local male goats were examined normal testes ultrasonic appearances. real time scanner with a 7.5 MHz, linear array transducer was used evaluate the echotexture testicular parenchyma, mediastinum epididymis. The parenchyma represented uniformly homogenous moderately echog...

background: sodium arsenite and/ or vasectomy may cause variation in sex hormones which affect pathophysiology of reproductive organs. objective: the aim was to investigate the morphological changes in structure of testis and hormonal imbalance in bilateral vasectomised rats treated with sodium arsenite. materials and methods: four groups of rats: bilateral vasectomy + sodium arsenite, bilatera...

The authors regret that in our published paper entitled “Comparative testis structure and function three representative mice strains.”

Background Despite the bulk of studies on fatty acid supplementation in maternal diet and confirmed the positive effects on brain and vision, these effects on offspring reproductive organs have not been tested. The aim of the present study was to stereological evaluate the effect of feeding Fish Oil (FO) for mothers on the testis structure of offspring. MaterialsAndMethods Sixty mature female N...

During surgical exploration for undescended testes (UDT) a situation arises where no testis could be found and labeled as an absent testis. An absent testis either unilateral or bilateral cannot exist without the presence of ipsilateral mullerian structure in unilateral cases and phenotypic appearance of female in bilateral ones. Understanding the embryological development of the testis and epi...

Changes in Sertoli cell numbers and testicular structure during normal development and compensatory hypertrophy were assessed in crossbred Meishan x White Composite males. Boars were assigned at birth to unilateral castration at 1, 10, 56, or 112 days or to remain as intact controls through 220 days. The first testes removed were compared to assess testicular development. At 220 days, testicula...

introduction: the impact of chromium exposure was studied on liver, kidney, testis, spleen, cerebrum and cerebellum of male wistar rats (80-100 g body weight). material & method: it was observed that treatments of rats with chromium (i.p. at a dose of 0.8 mg / 100 g body weight per day) for a period of 28 days caused significant increase in chromium content while declining the body weight along...

background: busulfan (bus) is a chemotherapy drug that is widely used for cancer treatment. however, administration of busulfan may cause temporary or permanent sterility in male patients. therefore, reduction of this side is necessary. objective: evaluation of the protective effects of l-carnitine and testis homogenized tissue (tht) on sperm parameters and the testis structure after busulfan t...

Taphozous longimanus (Hardwicke) is a continuous breeder as males show full spermatogenic activity throughout the year. Microscopic study of testis reveals that immature, pre-breeding and sexually active males occur round the year. The testis shows variations in its structure during the different stages of breeding activity. In the pre-breeding period, testis shows various stages of spermatogen...
