Biological samples are vulnerable to degradation from the time they are collected until they are analysed at the laboratory. Biological contaminants, such as bacteria, fungi, and enzymes, as well as environmental factors, such as sunlight, heat, and humidity, can increase the rate of DNA degradation. Currently, DNA samples are normally dried or frozen to limit their degradation prior to their a...

background: pentoxifylline (px) prevents camp breakdown by inhibiting the activity of the camp-phosphatase and presumably, stimulates sperm motion. incubation with px causes hyperactivation of sperm, an important step in achieving fertilization, and leads to changes in membranes associated with sperm capacitation. objective: the purpose of this study was to examine the effects of pentoxifylline...
