BACKGROUND Recommendations for cardiovascular disease prevention advocate lowering both cholesterol and low-density lipoprotein cholesterol systemic levels, notably by statin intake. However, statins are the subject of questions concerning their impact on male fertility. This study aimed to evaluate, by a prospective pilot assay, the efficacy and the toxicity of a decrease of cholesterol blood ...
The aims of this study were to assess and compare the effect of skim milk with (MEY) and without (SMI) egg yolk on canine spermatozoa incubated at 4oC in vitro and to evaluate the efficacy of MEY in vivo. Also, the effect of semen cooled storage before freezing was also evaluated in vitro. The ejaculates of 10 dogs were collected, pooled, centrifuged, and divided into 4 aliquots and diluted in ...
such as varicocele, inflammation, and smoking, are well known to influence the balance between radical production and antioxidant defense. The objective of the present study was to select an efficient Non-steriod Anti- inflammatory Drugs (NSAIDs) concentrations of sperm activation in vitro for patient complaining from astheno-leucozoospermia. In vitro sperm activation was performed on seminal fl...
objective: to evaluate the efficacy of in vitro sperm activation (isa) using non-liquefied versus liquefied asthenozoospermic semen samples for improvement of sperm parameters. materials and methods: fifty six oligoasthenozoospermic (oa) patients (age range: 22-44 years; mean: 32.089 years) were enrolled in this study. oa patients were classified according to type of infertility. also, duration...
Background Levels of serum gonadotropins have direct effects on testicular functions and spermatogenesis. Assessment of levels of serum gonadotropins from fathered subjects and infertile patients indicates wide range diversity. In this study, we tried to find out whether the levels of seminal FSH and LH affect the parameters of seminal fluid analysis (SFA) and if there is any correlation betwee...
Background: Oligoasthenospermia (OAS) is a condition characterized by low sperm count associated with low sperm motility. Medical treatment is not known in allopathic system for treatment of oligoasthenospermia. Homeopathic medicine is effective in more than 95% patients. Oxidative stress and decreased antioxidant levels have been projected as a potential factors involved in the pathophysiology...
The aim of this study was to determine whether flow cytometric evaluation of combined merocyanine 540 and Yo-Pro 1 (M540-YP) staining would identify viable dog sperm that had undergone membrane stabilization known to be associated with capacitation in other species, and whether such destabilization is detected earlier than when using the tyrosine phosphorylation and ethidium homodimer (TP-EH) s...
BACKGROUND The 2013-2016 West African Ebola virus disease epidemic was unprecedented in terms of the number of cases and survivors. Prior to this epidemic there was limited data available on the persistence of Ebola virus in survivors' body fluids and the potential risk of transmission, including sexual transmission. METHODOLOGY/PRINCIPAL FINDINGS Given the urgent need to determine the persis...
the aim of this study was to evaluate the effects of the addition of antioxidants (vitamin e, β- mercaptoethanol and their combination) to semen extender. progressive motility, viability and ph of fresh ram semen were examined. ejaculate samples were collected with artificial vagina from three ghezel-merinose rams (3 years old) during non- breeding reproduction season. semen was diluted with a...
