Spermine and Citric Acid in Human Prostatic Fluid

Abstract

Concentration of spermine (87 ± 13 μM) and citric acid (45 ± 4 mM) in prostatic fluids from 44 men were highly significantly correlated (r = 0.795). It was concluded that both probably arise from the same exocrine cell.

Polyamines and other accessory sex gland secretions in human seminal plasma 8 years after vasectomy

“…In spite of these published observations, there is a paucity of studies on the effects of vasectomy on accessory sex gland func¬ tion in the human male. Furthermore, a critical analysis of the world literature revealed that, in the majority of human studies, glandular function was monitored by examining the concentrations of secretory products in the ejaculate (Grégoire & Moran, 1972, 1973Kothari et al, 1977;Barkan et al, 1978;Nikkanen, 1978;Mendiratta et al, 1980;Naik et al, 1980;Bendvold et al, 1985;Parrish et al, 1987). Seminai plasma is a complex mixture of the products of several glands and it may therefore be more correct to compare glandular function on the basis of their total contributions to the ejaculate.…”

Morphodynamic and biochemical assessment of seminal plasma in patients who underwent local prostatic hyperthermia

“…Fructose is the main substance secreted by the seminal vesicles and it is of paramount importance for the glycolitic metabolism of spermatozoa as they possess minimal storage of glycogen and thus depend on vesicular fructose [22]. Citric acid is mainly of prostatic origin and its increase in the ejaculate is always dependent on an androgen-stimulated elevation of prostate metabolism [23]. Citric acid has an important role in redox reactions of the glucides metabolism; moreover it activates prostatic acid phosphatase.…”
