Seminal fructose and glucose in asthenozoospermia

Re: Sperm Motility Inversely Correlates with Seminal Leptin Levels in Idiopathic Asthenozoospermia.

BACKGROUND Asthenozoospermia is one kind cause of male infertility. Nevertheless, no specific etiology can be identified by routine tests in some cases. Recently, it has been shown that leptin plays a critical role in male fertility. However, the link between leptin and sperm motility is yet to be determined. The aim of this study was to explore association between seminal and serum leptin leve...

Glucose and fructose absorption in idiopathic steatorrhoea.

Seminal Fructose in Various Classes of Infertile Patients

Background: A great number of substances have been found in sperm plasma but so far it has not been possible to provide evidence of clinical significance for all of them. Fructose occupies the most important place in biochemical investigations. Fructose acts as a donor of energy to the spermatozoa. Fructose is secreted from the seminal vesicles and the accessory sex glands. It is the major carb...

Evaluation of LDH Activity and Its Relationship with Fructose Levels in Seminal Plasma of Normospermic and Asthenospermic Males

ABSTRACT         Background and Objectives: sperm motility mainly depends on aerobic glycolysis, and lactate dehydrogenase (LDH) is a key enzyme in the last step of this process. On the other hand, fructose is considered as the main energy source for sperm motility. Therefore, this study aimed to evaluate the LDH activity and fructose levels and their cor...

Fructose, Glucose, and Galactose Tolerance in Dogs

In a recent study, Folin and Berglund (1) describe certain phenomena associated with the transportation, retention, and excretion of carbohydrates. Data are presented to show that both fructose and galactose are less effective than glucose in raising the level of the blood sugar. The explanation offered is that the tissues, being relatively well stored with glucose and empty of other sugars may...
