Sperm aging is defined as a gradual and irreversible decay in structural mechanochemical and fertilizing properties of mature spermatozoa. Research using artificial means such as cold shock freezing and thawing dilution and washing treatment with spe

When fructose was established as the normal nutrient material for spermatozoa and its origin traced to the seminal vesicles1, it remained to be explained how certain animals, such as the rabbit, secrete fructose in semen in spite of the absence of se

Previous experiments have established the fact that mammalian semen contains fructose, its concentration varying from a few mgm. per cent in boar to 1,000 mgm. per cent in bull; this sugar serves the spermatozoa as their natural nutrient, and they re

During in vitro incubation at 8 °C the glycogen reserve of octopus spermatozoa undergoes glycogenolysis. For the first 48 h, during which motility remains high, the formation of D (−)lactic acid accounts for most of the metabolized glycogen. Upon

Carnitine and glycerylphosphorylcholine, two well-known constituents of the mammalian epididymis, are shown to be equally characteristic of another sperm-storing organ, namely the spermatophore of a cephalopod mollusc, Octopus dofleini martini .

Peroxidation of the sperm cells’ own phospholipids, closely bound up with declining motility, has been demonstrated in human spermatozoa; the rate of peroxidation was determined quantitatively by the reaction with thiobarbituric acid. Immotile or p
