Assessment of gonadal maturation by evaluation of spermaturia. [PDF]
The urinary excretion of spermatozoa (spermaturia) reflects the achievement of exocrine testis function during male puberty. In order to test the sensitivity and practicability of repetitive urine sampling, we analysed the sediments of 1160 first morning urine specimens obtained on successive days from 129 healthy schoolboys aged 10.1 to 17.8 years for

Metamorphosis and Gonad Maturation in the Horn FlyHaematobia irritans [PDF]
The bloodsucking horn fly, Haematobia irritans (L.) (Diptera: Muscidae), is one of the most damaging pests of pasture cattle in many areas of the world. Both male and female imagoes spend their adult stage on the host, while immature stages develop in dung. Our goal was to determine if the progress of H. irritans gonad maturation can be correlated with
