TLDR
The study revealed that liquefaction time-based fractionation of the whole ejaculate seems to give an idea about the origin of some seminal components like split ejaculation technique.Abstract:
Variations in the coagulation-liquefaction property of human seminal coagula have rarely been correlated to their ingredients. A number of seminal components were evaluated in relation to the degree of coagulation and the liquefaction time of human ejaculates. Correlation analyses suggested that the vesicular coagulatory activity can better be assessed by the phosphate level rather than the fructose and N-acetylamino sugar levels. The results showed that the fresh ejaculates with a smaller amount of coagulum possess significantly higher prostatic but lower vesicular activities in comparison with that of the better coagulating samples. The study also revealed that liquefaction time-based fractionation of the whole ejaculate seems to give an idea about the origin of some seminal components like split ejaculation technique. It was concluded that the material characteristics of human ejaculate can be approximated simply by determining its degree of coagulation or liquefaction time.read more

TL;DR: Among these properties, pH and buffering capacity, osmolarity, ionic strength, and rheological properties play dominant roles in the physico-chemical processes that govern drug release kinetics and delivery vehicle distribution.

Functional Structure and Ultrastructure of Seminal Vesicles
TL;DR: The use of a new marker of the seminal vesicle function, termed corrected fructose, demonstrates an association between serum testosterone levels and seminal corrected fructose levels.

Biochemical composition of washed human seminal coagulum in comparison to sperm-free semen from the same donors.
A. Mandal,A. K. Bhattacharyya +1 more
TL;DR: Intra-individual inter-ejaculate variations in the amounts of protein, fructose, N-acetylamino sugar, phosphate, sialic acid and amino sugar in washed coagulum from normal ejaculates of men were highly consistent.

Differences in osmolality, pH, buffering capacity, superoxide dismutase and maintenance of sperm motility in human ejaculates according to the degree of coagulation.
TL;DR: It is suggested that subfertility may be associated with poor coagulation of ejaculates, and no correlation was obtained between the activity of superoxide dismutase and the amount of coagulum.

Semen characteristics of the adult male chimpanzee (Pan troglodytes).
TL;DR: In this paper, the authors provided baseline values for testicular volume without and with pressure and for cellular and biochemical characteristics of ejaculates collected by artificial vagina (AV) collected by five adult male chimpanzees.

Green Chemistry: Theory and Practice
Paul T. Anastas,John C. Warner +1 more
TL;DR: Green Chemistry: What is green chemistry? as discussed by the authors presents the principles of green chemistry and evaluates the impact of chemistry on the environment. But, it is not a complete overview of all of the issues involved in green chemistry.

Assay of inorganic phosphate, total phosphate and phosphatase
TL;DR: The method is about seven times as sensitive as the Fiske–SubbaRow procedure and involves less pipetting, but it is not very satisfactory for determining inorganic phosphate if labile phosphate esters are present in large excess.

E. Melvin Gindler,John D. King +1 more
TL;DR: A simple and rapid colorimetric method of determining calcium concentration, based on methylthymol blue, is described, which agrees closely with Gitelman’s o-cresolphthalein complexone procedure, and good accuracy has been shown by recovery data.

Male Reproductive Function and Semen: Themes and Trends in Physiology, Biochemistry and Investigative Andrology
TL;DR: Alcohol’s Effects on Male Reproduction The male reproductive system consists of the hypothalamus, the anterior pituitary gland, and the testes, and alcohol can interfere with the function of each of these components, thereby causing male infertility.
