This study was conducted to assess the physical and morphological characteristics of fresh, pre-freeze and post-thaw black Bengal buck (Capra hircus) semen processed in Tris-egg yolk-citrate-fructose-glycerol (TEYCFG) extender containing 4 different concentrations (2.5, 5, 7.5 and 10%) of egg-yolk. Ejaculates were collected once a week for eight weeks from six mature bucks (48 ejaculates) using...
The main purpose of this study was to evaluate the influence of the photoperiod on the seminal traits of crossbreed wool-producing rams throughout on year period. For the effect of photoperiod two periods were considered: decreasing daylight length (summer and autumn) and increasing daylight length (winter and spring). For the study 5 Baluchi × Moghani (BL×MG) and 5 Arkharmerino × Moghani (AM×M...
Background and Purpose: There is evidence in literature that IUI is the first line treatment and the most cost-effective procedure for mild to moderate male factor sub-fertility, however, the relative influence of various semen characteristics with the likelihood of a successful outcome is controversial.

Background Sperm motility is known as an effective parameter in male fertility and it depends on energy consumption. Low level LASER irradiation could increases energy supply to the cell by producing of adenosine triphosphate (ATP). The purpose of this study is to evaluate how the low level LASER irradiation affects the human sperm motility. MaterialsAndMethods Fresh human semen specimens of as...
