oligospermia/hypoxia

Three groups of patients were analysed: varicocele patients with abnormal seminal fluid (17 cases), variococele and normal sperm (seven cases) and normal males (17 cases). Blood gas was secured in the internal spermatic vein, perpheric vein and femural artery, in an attempt to evaluate the

Hypoxia in vivo induces oligozoospermia, azoospermia, and degeneration of the germinal epithelium, but the underlying molecular mechanism of this induction is not fully clarified. The aim of this study was to investigate the role of the death receptor pathway and the mitochondrial pathway in

BACKGROUND The aim of this study was to explore the effect of obstructive sleep apnea hypopnea syndrome (OSAHS) on spermatogenesis and the effects of the expression of related proteins. MATERIAL AND METHODS Rats in Group A were normoxic (exposed to a normal level of oxygen). Rats in Group B were

OBJECTIVE To evaluate the effect of chronic hypoxia on human spermatogenic parameters and their recovery time. METHODS Seminological parameters of six male healthy mountain trekkers were evaluated in normoxia at sea level. After 26 days exposure to altitude (ranging from 2 000 m to 5 600 m,

Aquaporin-9 (AQP-9) regulates tissue hydration by promoting transmembrane exchanges of both water and solutes, such as lactate. The latter is a key metabolite of primary spermatocytes and of maturing haploid germ cells (h-GCs). The present investigation was aimed at immunolocalising human AQP-9 in

The precise mechanism of the hypospermatogenesis associated with varicocele has remained uncertain, although there have been a number of speculations on the etiology of the associated infertility. The altered spermatogenesis has been attributed to the reflux of toxic metabolites from either adrenal

OBJECTIVE To investigate primary lesions in twisted testes. METHODS The histologic study of testicular specimens obtained from men who had suffered testicular torsion. METHODS The conditions required for material selection were the knowledge of the exact time of torsion and the presence of

UNASSIGNED To investigate the characteristics of the semen parameters of native Tibetans and immigrated Tibetan Hans in the high-altitude area and analyze the influence of altitude adaptation on male fertility. METHODS This study included 1 563 infertile male patients, including 698 native Tibetans

A disorder caused by congenital ciliary dysfunction occurs in dogs. Most of the clinical signs are directly or indirectly attributable to immotile or dyskinetic cilia and spermflagella. Due to severely impaired mucociliary clearance, a continuous mucoid nasal discharge and intermittent sneezing and

Male reproductive function has been poorly studied in sickle cell disease. Low sperm count, impaired motility of spermatozoa and spermatogenic arrest during testicular biopsies have been described in this situation. In the present series of patients, the main seminal changes found were reduced
