Introduction: Testicular microlithiasis is an uncommon condition characterized by calcifi cations within the seminiferous tubules. The true prevalence in a normal population has not been defi ned. Methods: A review of the literature with emphasis on the connection between testicular microlithiasis and testicular malignancy was carried out. Results: Testicular microlithiasis is associated with d...

AIM To evaluate the relationship between testicular function and testicular volume measured by using Prader orchidometry and ultrasonography (US) to determine the critical testicular volume indicating normal testicular function by each method. METHODS Total testicular volume (right plus left testicular volume) was measured in 794 testes in 397 men with infertility (mean age, 35.6 years) using...

OBJECTIVE To prospectively determine the prevalence of testicular microlithiasis in symptomatic patients who were referred for scrotal ultrasound examination and to evaluate the possible association of testicular microlithiasis with testicular cancer and other conditions such as cryptorchidism or history of ascending testis. MATERIALS AND METHODS 391 men who were referred to our institutions ...

background: spermatogonial stem cells are subpopulation of spermatogonial cells in testis tissue that support beginning and maintenance of spermatogenesis. ubiquitin carboxy-terminal hydrolase l1 (uchl1) could be a specific marker for identification of spermatogonial stem cells including spermatogonial sperm cells (sscs) in testis tissue and during the culture; therefore we undertook this study...

BACKGROUND Testicular biopsy is an acknowledged method of examination of the testes for diagnostic and therapeutic purposes. We describe the pattern of testicular histologies in our environment. MATERIALS AND METHODS We carried out a retrospective review of testicular histology results from the Pathology Department of Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, over a 5-year p...

PURPOSE We assessed reproductive and testicular function in adult rats after testicular torsion created before, during and after puberty, and with vs without resveratrol or arginine treatment. MATERIALS AND METHODS Age matched rats were divided into groups, including simulated surgery without testicular torsion, 720-degree testicular torsion for 4 hours, testicular torsion with resveratrol tr...

Purpose: To determine prospectively the prevalence of testicular microlithiasis in symptomatic patients who were referred for scrotal ultrasound examination and to evaluate the possible association of testicular microlithiasis with testicular cancer. Material and method: 391 men who were referred to our institution between July 02 and May 05 for any type of symptoms from the testicles underwent...

conclusions the inhibition of mini-puberty period in male rats was demonstrated to have an effect on their testicular function to some extent. results serum t and lh levels peaked at two hours after birth, while fsh peaked at hour 0, and bilateral testicular weight peaked at four hours after birth. the rats that underwent ether inhalation five minutes after birth had markedly reduced serum horm...

adenocarcinoma of the stomach was the leading cause of cancer-related death worldwide through most of the 20th century. usual presentations of gastric cancer include anorexia, epigastric pain or discomfort and weakness. rarely, patients present with unusual clinical manifestations. in this article, we report two cases with uncommon presentations of gastric adenocarcinoma. the first patient was ...

background: in radiation therapy, peripheral dose or the dose outside the radiotherapy field, is important when anatomical structures with very low dose tolerances are involved. one of these critical organs in pelvic irradiation is testis. the amount of radiation delivered to the testes in radiotherapy must be kept as small as possible, consistent with the limit dose of this organ. the threshol...
