BACKGROUND: Beta thalassemia is an inherited hemoglobin disorder resulting in chronic hemolytic anemia. RBCs hemolysis and repeated blood transfusions are the major causes of secondary iron overload which leads to deposition of iron in different endocrine glands. Delayed puberty and hypogonadism are the most obvious clinical consequences of iron overload. The aim of this study was to evaluate male sex hormone levels in male children with β- thalassemia major in correlation with iron overload...

INTRODUCTION: Testicular size is commonly used as a proxy for future fertility in adolescent boys diagnosed with varicoceles. Surgery is often performed based on a 15-20% reduction in volume of the ipsilateral testicle when compared to the unaffected side. Recent European Association of Urology guidelines, however, have highlighted the risk of overtreatment. Data on the natural progression of testicular size discrepancy are limited in this population. To evaluate the role of a non-surgical approach, the present study reports on testicular size progression in 35 boys with left-sided varicoceles managed with observation alone...

AIM: Accurate calculations of testicular volume standard deviation (SD) scores are not currently available. We constructed LMS-smoothed age-reference charts for testicular volume in healthy boys. METHODS: The LMS method was used to calculate reference data, based on testicular volumes from ultrasonography and Prader orchidometer of 769 healthy Dutch boys aged 6 months to 19 years. We also explored the association between testicular growth and pubic hair development, and data were compared to orchidometric testicular volumes from the 1997 Dutch nationwide growth study...

BACKGROUND: Infertility affects ∼7% of all men. Despite much progress, mainly in genetics, its etiology remains obscure in ∼50% of cases. To fill this gap, imaging of the male genital tract (MGT) has progressively expanded, providing useful information in the assessment of MGT abnormalities. METHODS: A critical, systematic review of the available literature was performed using Medline, with no restrictions regarding date of publication (i.e. from inception date until March 2014), along with analysis of previous reports in color Doppler ultrasound (CDUS) atlas textbooks...

In the last 30 years, scientific literature has been enriched with studies which demonstrate the importance of evaluating testis volume to recognize certain genetic and endocrine diseases. Macroorchidism is defined as an increase of testicular volume at least twice the norm for age. In clinical practice, when macroorchidism is suspected, the testicular volume may be evaluated with the Prader orchidometer and/or US, calculated by this formula: L x W x H x 0.71 and the resulting value should be compared with a table of percentiles for each age...

BACKGROUND: Seminiferous tubules comprise 80-90% of testicular mass. Thus, the testicular volume is believed to be an index of spermatogenesis. Therefore, accurate testicular volume is one way to assess testicular function. OBJECTIVE: To determine the accuracy of Prader orchidometer for measuring the testicular volume by comparing the resultant measurement with the actual testicular volume in humans. MATERIALS AND METHODS: The testicular volumes of 121 testes from 62 patients with prostate cancer (mean age 72...
