Abstract Isotomus speciosus is a polyphagous insect that damages coniferous and deciduous trees. There no study on the male reproductive system of I. although it an important pest. For this purpose, anatomy histology were investigated using light scanning electron microscopy. According to results obtained, consists pair testes (each with separate testis lobes), two pairs vasa efferentia, defere...

Objective: To describe the aetiology and efficacy of the treatment of persistent and recurrent hemospermia as a novel technique of transurethral seminal vesiculoscopy. Methods: The clinical data of 290 patients with persistent and recurrent hemospermia (a course of hemospermia persisting more than 6 months) from multiple medical center of South China were analyzed retrospectively. The age range...

BACKGROUND The male reproductive system of insects can have several tissues responsible for the secretion of seminal fluid proteins (SFPs), such as testes, accessory glands, seminal vesicles, ejaculatory duct and ejaculatory bulb. The SFPs are transferred during mating and can induce several physiological and behavioral changes in females, such as increase in oviposition and decrease in sexual ...

A male factor i s sole ly responsible in approximately 20% of cases of infertility and contributory in another 30-40%. Azoospermia is present in 1520% of infertile males. Although the main goal of the evaluation of the infertile men is to identify the reversible conditions, to identify the irreversible causes that can or cannot be managed by assisted reproductive techniques (ART) is also import...
