Genital and sperm characteristics of wild, free rangingred deer stags (Cervus elaphus L) hunted in different regions Abstract In an attempt to establish reference values for sperm morphology in wild red deer, genital tracts were collected from thirty-six 3-11 years old free-ranging, wild red deer stags (Cervus elaphus L) shot down during 3 consecutive mating seasons (1996-1998) at three differe...

Male carriers of Robertsonian (Rob) translocations can have fertility problems associated with low sperm counts and abnormal sperm morphology. In this study, spermatozoa from 14 Rob translocation carriers, seven der(13;14), two der(13;15), two der(14;15), two der(14;21) and one der(21;22), were tested by fluorescence in-situ hybridization (FISH) for the chromosomes involved, to study meiotic se...

Hybridization tests of laboratory-raised, isolines of Anopheles minimus, species A and C were conducted by induced copulation. The three isolines were established based on three morphological variants of wild-caught, fully engorged females and two distinct types of metaphase chromosomes. They were An. minimus species A: V form (X1,Y1), M form (X2,Y1); species C: P form (X3,Y2). The results of r...

The aim of the present study is to investigate the effect of L-ascorbic acid on postnatal exposure of endosulfan induced testis damage in the rat. Four groups of seven day old male Wistar rats were treated with 3, 6, 9 and 12 mg/kg endosulfan orally (10 pups/group), from postnatal day 7 to 60 at intervals of 24 h. For 2 more groups (n = 10/group), endosulfan (9 mg/kg and 12 mg/kg) was administe...

A retrospective survey was undertaken of the clinical EEG in a series of consecutive admissions to Broadmoor Special Hospital (N = 265). Following reporting of the records by visual inspection, the EEGs were classified according to 4 descriptive categories: predominantly monorhythmic; low voltage fast, 'choppy'; dysrhythmic with excess theta; and dysrhythmic with paroxysmal features. The last 3...

objective: globozoospermia is a rare type of teratozoospermia with incidence of 0.1% among infertile individuals. phospholipase c zeta (plcζ) and postacrosomal sheath ww domain binding protein (pawp) are the main candidates in sperm taking responsibility for oocyte activation during fertilization. therefore, we aimed to evaluate the expression of these two genes at rna and protein levels in glo...

BACKGROUND Human fertility is linked to sperm quality and therefore the establishment of reference values for normality is mandatory. AIMS The first aim was to establish a reference profile of men in the general population by examining the semen of partners of women with chronic anovulation. The second aim was to determine the prevalence of sperm abnormalities in this patient group. METHODS...
