The concentration of coenzyme Q10 (CoQ10), a key intermediate of the mitochondrial respiratory chain, was determined in spermatozoa of 13 fertile subjects, 8 potentially fertile patients, and 12 infertile patients. CoQ10 concentrations were significantly higher (P < 0.001) in infertile patients than in fertile and potentially fertile subjects. The difference between potentially fertile and fert...

BACKGROUND The period in each menstrual cycle during which sexual intercourse can result in conception is called the "fertile window". Although the fertile window closes on the day of ovulation, little is known about the moment it opens. We defined the first day of normal sperm-mucus interaction as the opening of the fertile window. We hypothesized that length of the fertile window varies betwe...

In recent years, with the effect of climate change, drought is accepted as one most important natural disasters. planning, development and management processes water resources, studies on analysis past droughts decreasing possible negative effects in future, have become even more substantial. The best adaptation to risk can only be achieved by adopting holistic approaches. this study, Dörtyol-E...
