2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and dioxin-like compounds are widely encountered toxic substances suspected of interfering with the endocrine systems of humans and wildlife, and of contributing to the loss of fertility. In this study, we determined the changes in testicular gene expression caused by in utero exposure to TCDD along with the intra-testicular testosterone levels, epidid...

Malacoplakia is a chronic inflammatory disease. The disease mainly affects the urinary bladder, although involvement of extravesical sites is increasingly being documented. Most frequently involved is the urinary tract, particularly the urinary bladder, although the testis, epididymis, lungs, bone, colon, prostate, female genital organs, and retroperitoneum can also be involved. Here we report ...

The present study investigates the anti-spermatogenic potential of ethanolic extract of Matricaria recutita a plant belonging to Asteraceae family. The effects of an ethanolic extract of the Matricaria recutita on spermatogenesis, histology of testis and level of testosterone were examined in control and experimental groups. Results showed that Matricaria recutita extract did not cause any chan...

A 51-year-old man presented with a 2-year history of painless lump in the left hemiscrotum. Scrotal examination demonstrated a 3-cm, firm-to-hard mass attached to the left spermatic cord. Scrotal ultrasound scan revealed a heterogeneous mass separate from the left testis and epididymis. An orchidectomy was recommended to the patient; however, he declined surgery and underwent excision biopsy of...

The reproductive cycles of lizards, including Tropidurus species, have been widely studied. However, few studies describe in detail the ultrastructure and the epithelial changes in the epididymis. Using histology and trasmission electron microscopy, we show the seasonal changes in the testis and epididymis of the lizard Tropidurus itambere, during its annual reproductive cycle. The reproductive...

Benign prostatic hyperplasia (BPH) is a common disease in elderly men. Although it is a nonmalignant disease, it can have a significant impact on the quality of life of elderly men. The pumpkin seed is claimed to be useful in the management of BPH. This investigation analysed the chemical composition of pumpkin seeds and examined its effect on citral-induced hyperplasia of the prostate in Wista...

BACKGROUND The predominant phytoestrogen in soy and derived products is the isoflavone Genistein. Genistein has antioxidant properties. Morphine is a main psychoactive chemical in opium that can increase the generation of free radicals and therefore it could adversely affects the spermatogenesis. OBJECTIVE The main goal was to investigate whether the Genistein could protect morphine adverse e...

Serological screening approaches have allowed for the identification of a large number of potentially relevant tumor antigens in cancer patients. Within this group, cancer testis antigens represent promising targets for cancer immunotherapy, since they are widely expressed in a variety of human cancer entities. In pancreatic cancer, however, there are only few data available about the expressio...

A 11-year-old boy had long-standing, asymptomatic para-testicular mass inside the left hemiscrotum. Physical examination identifi ed a double, superimposed, non-adherent scrotal mass. Color Doppler ultrasonography indicated normoechogenic homolateral testes and epididymides, with individual blood vessel networks. The right testis measured 40 × 19 mm; on the left, the lower testis was 21.8 × 15....

BACKGROUND Testicular torsion due to oxidative stress results in infertility and testicular damage which can be preventable an important health problem worldwide. AIM The purpose of the present study was to investigate the changes of malondialdehyde (MDA), total antioxidant status (TAS), total oxidant status (TOS) levels; histopathological alterations; morphology, concentration and motilities...
