The standard semen analysis is the first line and the most popular laboratory test in the diagnosis of male fertility. It evaluates sperm concentration, motility, morphology and their vitality. However, it is well-known that normal results of semen analysis can not exclude men from the causes of couples' infertility. One of the most important parameters of sperm in its fertilizing potential is ...

OBJECTIVES Bisphenol A diglycidyl ether (BADGE) is a liquid compound obtained by condensation of two molecules of epichlorohydrin with one molecule of bisphenol A. General and reproductive toxicity with BADGE has been reported higher than 1000 mg/kg/day. This study was performed to show the effects of acute exposure to BADGE below 1000 mg/kg/day on the testis in adult male rats. METHODS BADGE...

The genetic basis of hybrid male sterility in house mice is complex, highly polygenic, and strongly X linked. Previous work suggested that there might be interactions between the Mus musculus musculus X and the M. m. domesticus Y with a large negative effect on sperm head morphology in hybrid males with an F1 autosomal background. To test this, we introgressed the M. m. domesticus Y onto a M. m...

Lead is one of the industrially heavy metals that caused adverse effects on male reproductive system among battery factory workers, but information on the possible impact of lead on the structural integrity of sperm cell is limited. Thus present study was undertaken to assess the structural details of human spermatozoa of lead acid battery factory workers. Blood and semen samples were collected...

formalin is widely used in industry and in medicine (as tissue fixative and disinfectant).it contains reactive molecules which have been known for its cytotoxic effects. to evaluate the effect of formalin exposure on the testicular tissue and sperm parameter from neonatal period through physical and sexual maturity, 28 male wister rats were assigned into two equal test and control groups. the t...

Background: It is showed that methamphetamine has harmful effects on male reproductive system. The aim of this study was to investigate the effects of methamphetamine administration on testis weight, sperm count, sperm morphology, and chromatin status as well as sperm apoptotis followed by the cytochemical tests in a mouse model. Materials and Methods: Twenty four NMRI male mice were divided in...

Recurrent miscarriage affect on the female reproductive health and family harmony. For a long time, the medical assessment of the recurrent miscarriage mainly focus on the female. The role of the male factors during the process of recurrent miscarriage has not been known and need further discussing.
