Seminal Plasma Biological Fluid

Seminal plasma is the liquid; non-sperm; portion of an ejaculation. Semen is centrifuged to seperate the sperm from the seminal fluid.
During the process of ejaculation; sperm passes through the ejaculatory ducts and mixes with fluids from the seminal vesicles; the prostate; and the bulbourethral glands to form the semen. The seminal vesicles produce a yellowish viscous fluid rich in fructose and other substances that makes up about 70% of human semen. The prostatic secretion; influenced by dihydrotestosterone; is a whitish (sometimes clear); thin fluid containing proteolytic enzymes; citric acid; acid phosphatase and lipids. The bulbourethral glands secrete a clear secretion into the lumen of the urethra to lubricate it.
Sertoli cells; which nurture and support developing spermatocytes; secrete a fluid into seminiferous tubules that helps transport sperm to the genital ducts. The ductuli efferentes possess cuboidal cells with microvilli and lysosomal granules that modify the semen by reabsorbing some fluid. Once the semen enters the ductus epididymis the principle cells; which contain pinocytotic vessels indicating fluid reabsorption; secrete glycerophosphocholine which most likely inhibits premature capacitation. The accessory genital ducts; the seminal vesicle; prostate glands; and the bulbourethral glands; produce most of the seminal fluid.

Small volumes of Seminal Plasma biological fluid vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
