Background: The success of fertilization is directly associated with semen quality and the sperm preparation. Considering the common use of cryopreserved spermatozoa, there is a need to develop strategies for sperm preparation in order to achieve a sperm sample of high quality through a rigorous selection of sperm. Thus, sperm cells are being more extensively investigate. This study aimed evalu...
Background: Obesity is a leading preventable cause of death worldwide, with increasing prevalence in adults and children. Some studies have shown that increased body mass index is related to poor semen quality, decreased sperm concentration, decreased normal-motile sperm cells and increased DNA fragmentation index. Lipid peroxidation contributes to the damage of the sperm plasma membrane. Cinna...
PURPOSE To date, standard semen parameters have been the only parameters investigated in sperm samples of infertile men in Algeria. We investigated, for the first time, semen parameters according to sperm DNA fragmentation (SDF) in these subjects. MATERIALS AND METHODS SDF was determined by a validated sperm chromatin dispersion test in 26 infertile men. Patients were split into two groups ac...
BACKGROUND There are few studies indicating the detrimental effects of ibuprofen on sperm fertility potential and DNA integrity. OBJECTIVE To determine the effects of Ibuprofen on sperm parameters, chromatin condensation and DNA integrity of mice. MATERIALS AND METHODS In this experimental study, 36 adult male mice with average weight 37 gr were divided into three groups, including control ...
A field trial was conducted to compare the fertility predicting capacity of different sperm assays applying classical semen analysis, sperm function and the homologous in vitro penetration test (hIVP) to 60 ejaculates from four boars collected over a period of 15 weeks. No differences were found between the groups of fertility (Low Fertility: < 20%; Intermediate: 40-60% and High: > 80%) for spe...
BACKGROUND Previous researches about the effect of smoking on semen quality are contradictory, and the mechanism behind the harmful effect of smoking on semen quality still remains unclear until today. OBJECTIVE The objectives of this study are evaluation of the relationship between smoking and fertility, investigation of the effects of cigarette smoking on sperm parameters and detection of p...
Background and Aims: Due to the paucity of studies, association between the morphology and function of sperm and recurrent miscarriage (RM) is not yet completely known. Increased reactive oxygen species and decreased antioxidant levels in men have been shown to be associated with RM. Recently it has been accepted that antioxidant therapy can approve sperm parameters. The goal of this study was ...
Objective- Release of free radicals and oxidants following increased temperature of testis in cryptorchidism, play an important role in the producing testicular damage. The present study investigated the role of vitamin C as an antioxidant in protecting the testis against damage in experimental unilateral cryptorchidism. Design- Experimental study Animals- Forty five male adult Wistar–Albino ...
Background: Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer and infertility and dub fertility. Some studies have associated the body mass index (BMI) with reproductive parameters in men, showing that increased BMI is related to poor semen quality, decreased sperm concentration, decreased normal-m...
Background: The results of studies on the effects of age on sperm parameters are controversial. The aim of this study was to evaluate the association of age and semen parameters. Methods: In this study 278 men (32.3±6.5 years, range 19 to 65 years) referred to a private medical laboratory to evaluate couple infertility were included from April 2016 to Mar...
