Semen characteristics were studied among 200 fertile Pakistani men aged 24 to 48 years. Each subject had fathered at least two children. The mean +/- SD values of volume, sperm density, motility percentage, grade of motility and percentage of oval sperms were 3.11 +/- 1.2 ml, 58.21 +/- 26.41 million/ml, 61.2 +/- 21.3%, 3.01 +/- 0.94 and 70.2 +/- 15.36% respectively. There was no deteriorating e...

background: this study was conducted to evaluate the effect of melatonin on semen quality and quantity changes and increase of reproductive efficiency in lori-bakhtiari ram in the non-reproductive season. objectives: the purpose of this study was to investigate the effect of melatonin on testicular size and semen qualitative and quantitative changes in the non-breeding season is lori-bakhtiari ...

Asian elephants (Elephas maximus) have highly variable ejaculate quality within individuals, greatly reducing the efficacy of artificial insemination and making it difficult to devise a sperm cryopreservation protocol for this endangered species. Because seminal plasma influences sperm function and physiology, including sperm motility, the objectives of this study were to characterize the chemi...

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...
