Male Fertility Factors
Since the early 60s, in our lab we sought useful correlations of seminal traits and fertility in order to ultimately predict the reproductive outcome of bovine semen used in artificial breeding or the fertility of a specific male under natural service. Despite these efforts, to this day we can only account for approximately 50-60% of the variation in fertility among males by measuring seminal t...
متن کاملAssessment of environmental factors affecting male fertility
Exposure to drinking water containing as much as 500 ppm aluminum chloride for periods of 30, 60, and 90 days had no apparent effect on male reproductive processes. In an attempt to correlate enzyme activity with particular spermatogenic cell types, postnatal development of testicular enzymes was studied. Eight enzymes were selected: hyaluronidase (H), lactate dehydrogenase isoenzyme-X (LDH-X),...
متن کاملManagement Factors Associated with Male Fertility
Artificial insemination (AI) is an efficient and cost-effective strategy to improve the genetics and reproductive performance of a herd. Reputable commercial AI stud and custom semen collection businesses, through stringent collection, processing and quality control, provide a highly fertile product to their customers. When semen is purchased and transferred to the producer’s liquid nitrogen re...
متن کاملNeuroendocrine Role of Kisspeptin-Neurokinin B-Dynorphin Pathway in Male Fertility and its Correlation with Melatonin
Introduction: A subset of neurons has been recently identified in the arcuate nucleus of the hypothalamus that co-localize three neuropeptides; kisspeptin, neurokinin B, and dynorphin (KNDy). These neuropeptides have been shown to play a critical role in the central control of reproduction and the modulation of gonadotrophin releasing hormone (GnRH) secretion by endocrine, metabolic and environ...
متن کاملThe role of oxidative stress and antioxidants in male fertility
Oxidative stress results from the imbalance between production of the reactive oxygen species (ROS) and the protective effect of the antioxidant system responsible for their neutralization and removal. An excess of ROS causes a pathological reaction resulting in damage to cells and tissues. Spermatozoa are particularly vulnerable to the harmful effects of ROS. Oxidative stress affects their act...
