[Reproductive function in chronic abacterial prostatitis patients].

The results of examination of 325 patients with chronic abacterial prostatitis, varicocele showed marked changes in ejaculate parameters of these patients. Prostatitis of different duration in the same degree causes pathozoospermia, reduces ejaculate fertility. Such condition of spermatogenesis indicates involvement of other sex organs suggested by the literature data and previous experience.

[Varicocele in children and adolescents].

We made examinations (physical, clinical and laboratory) of 301 senior children and adolescents with varicocele admitted to Research Institute of Urology for the last 5 years. Spermatogenesis was assessed by WHO criteria for healthy men. 78% of the patients were operated by Ivanissevich, 22% received sclerotherapy.

Male reproductive system in conditions of bed-rest in a head-down tilt.

Study of reproductive function in simulating experiments is important as for expansion of our theoretical knowledge in the field of gravitational physiology and space biology and for the decision of applied problems in space and clinical medicine. Long-term bed rest in a head-down tilt--6 degrees (BRHDT)--antiorthostatic hypokinesia is a wide spread method for ground-based simulation of space flight's conditions (mainly of hemodynamical effects of microgravity and restriction of locomotor activity). The aim of the present research was to study a reproductive function in males during 60-120 day BRHDT.
