In this study, quantitive characteristics and chemical composition of in roach (Rutilus rutilus caspicus) sperm were investigated. Sperm traits included sperm movement duration, percentage of motile spermatozoa, sperm density, spermatocrit and sperm volume. Some seminal plasma characteristics (sodium, potassium, calcium, magnesium and chloride) were investigated. In addition, some metabolites o...

To identify Kraft liquor effects on spermatogenesis and sperm motility of Caspian kutums by using in vitro culture, the fish testis was incubated with 5, 10 and 15 % (V/V) of liquor for 3 and 6 days. The percentage of motile spermatozoa and its total duration were also measured. Adverse effects on testicular cells were more apparent with the increase of liquor concentrations. The mean size of s...

in this study, the effect of hormon ovafact (gnrha) on biological semen characteristics (motility duration, percentage of motile spermatozoa, spermatocrit, sperm density, milt volume, ph, na+, k+, ca+, mg2+, total protein, cholesterol and glucose) in sub species commons, comets, wakins and fantail goldfish (carassius auratus gibelio) males was compared. from each treatment ten males has been in...

Damage occurring to spermatozoa during cryopreservation results in a loss of motile cells and cells that are functionally normal, compared with fresh sperm samples. Treating bull sperm with cholesterol-loaded cyclodextrins (CLC) before cryopreservation results in increased sperm cryosurvival. However, in previous studies, CLC were always added to sperm samples that had been highly diluted. The ...

background: sperm preparation is a fundamental step in art and attempt for developing new methods to be continued. objective: to evaluate the efficacy of upstream method for separation of human spermatozoa and its effects on sperm parameters including: motility morphology and concentration. materials and methods: semen samples from 17 men who referred to infertility clinic for evaluating their ...

BACKGROUND Sodium arsenite can impair male reproductive function by inducing oxidative stress. Silymarin is known as a potent antioxidant. OBJECTIVE This study was performed to investigate if silymarin can prevent the adverse effect of sodium arsenite on ram sperm viability, motility and mitochondrial membrane potential. MATERIALS AND METHODS Epidydimal spermatozoa obtained from ram were di...

PURPOSE For intracytoplasmic sperm injection in the absence of sperm motility it can be virtually impossible to distinguish viable from nonviable sperm. A reliable means to identify viable nonmotile sperm is needed and would likely improve the intracytoplasmic sperm injection success rate. Optoelectronic tweezers are a new technology that uses light induced dielectrophoresis fields to distingui...

Intracytoplasmic sperm injection (ICSI) is an extremely timeconsuming and tedious procedure in cases of oligozoospermia, because it is difficult to obtain a sufficient number of motile sperms. To circumvent this difficulty, we previously developed a microfluidic device to increase sperm concentration and reduce time required for ICSI. Here, we improved this device by carefully optimizing its di...

OBJECTIVES To report our experience with transurethral resection of the ejaculatory ducts (TURED) in infertile men with symptomatic ejaculatory duct obstruction (EDO). PATIENTS AND METHODS Before surgery, all patients complained of a decrease in the volume of their ejaculate, 14 of 15 had a non-projectile ejaculation, nine had a genitourinary infection necessitating antibiotic treatment, and ...

OBJECTIVE To explore the therapeutic effect of natural vitamin E (VitE) on oligospermia and asthenospermia in in- fertile men. METHODS We conducted a prospective multi-centered randomized controlled study on 64 infertile men with oligospermia (31 as controls treated with Tamoxifen 10 mg bid and 33 as experimental cases treated with Tamoxifen 10 mg bid + VitE 100 mg tid) and 42 cases of asthen...
