What is seminal plasma?
Seminalplasmin is a component of male seminal fluid. It acts as an antibiotic which has the capability of destroying certain bacteria. Because the female reproductive tract and the semen contain bacteria, the seminalplasmin helps to keep these bacteria under control; and thus helps protect the sperm and ensure fertilization which will lead eventually to reproduction. Please see the related link for more information.
What produces plasma hormones?
Plasma hormones are produced by endocrine glands in the body, such as the pituitary gland, thyroid gland, and adrenal glands. These glands release hormones directly into the bloodstream where they travel throughout the body to regulate various physiological processes.
Seminal plasma in human male is rich in?
Seminal plasma in human males is rich in proteins, fructose, enzymes, and other nutrients that support sperm health and motility. It also contains ions and other molecules that help regulate the pH and protect the sperm from the acidic environment of the vaginal canal.
Name all structures contributing to its formation and describe the composition of semen?
Composition of human semen: The components of semen come from two sources: sperm, and "seminal plasma". Seminal plasma, in turn, is produced by contributions from the seminal vesicle, prostate, and bulbourethral glands. Seminal plasma of humans contains a complex range of organic and inorganic constituents. The seminal plasma provides a nutritive and protective medium for the spermatozoa during their journey through the female reproductive tract. The normal environment of the vagina is a hostile one for sperm cells, as it is very acidic (from the native microflora producing lactic acid), viscous, and patrolled by immune cells. The components in the seminal plasma attempt to compensate for this hostile environment. Basic amines such as putrescine, spermine, spermidine and cadaverine are responsible for the smell and flavor of semen. These alkaline bases counteract the acidic environment of the vaginal canal, and protect DNA inside the sperm from acidic denaturation. The components and contributions of semen are as follows: Testes: 2-5%. Approximately 200- to 500-million spermatozoa (also called sperm or spermatozoans), produced in the testes, are released per ejaculation. Seminal vesicle: 65-75% amino acids, citrate, enzymes, flavins, fructose (the main energy source of sperm cells, which rely entirely on sugars from the seminal plasma for energy), phosphorylcholine, prostaglandins (involved in suppressing an immune response by the female against the foreign semen), proteins, vitamin C Prostate: 25-30% acid phosphatase, citric acid, fibrinolysin, prostate specific antigen, proteolytic enzymes, zinc (serves to help to stabilize the DNA-containing chromatin in the sperm cells. A zinc deficiency may result in lowered fertility because of increased sperm fragility. Zinc deficiency can also adversely affect spermatogenesis.) Bulbourethral glands < 1% galactose, mucus (serve to increase the mobility of sperm cells in the vagina and cervix by creating a less viscous channel for the sperm cells to swim through, and preventing their diffusion out of the semen. Contributes to the cohesive jelly-like texture of semen.), pre-ejaculate, sialic acid A 1992 World Health Organization report described normal human semen as having a volume of 2 ml or greater, pH of 7.2 to 8.0, sperm concentration of 20x106 spermatozoa/ml or more, sperm count of 40x106 spermatozoa per ejaculate or more and motility of 50% or more with forward progression (categories a and b) of 25% or more with rapid progression (category a) within 60 minutes of ejaculation.
What protection of the sperm against bacteria is the function of?
The protection of sperm against bacteria is primarily the function of the seminal plasma, which is the fluid that makes up most of the ejaculate. The seminal plasma contains antibacterial substances such as enzymes, antimicrobial peptides, and immunoglobulins, which help to inhibit the growth and activity of bacteria. Additionally, the acidic pH of the vagina also provides a natural barrier against bacterial infections.

What makes the liquid part of semen?
The liquid part of semen is primarily made up of fluids from the seminal vesicles and prostate gland. These fluids provide nutrients and protection for sperm as they travel through the reproductive tract. Additionally, small amounts of fluid from the bulbourethral glands may also be present in semen.
What adds a chemical fluid to the semen?
The seminal vesicle adds a sugary rich and nutritious fluid to the sperm.

What is semen made out of?
Composition of human semenDuring 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.[1] The prostatic secretion, influenced by dihydrotestosterone, is a whitish (sometimes clear), thin fluid containing proteolytic enzymes, citric acid, acid phosphatase and lipids.[1] The bulbourethral glands secrete a clear secretion into the lumen of the urethra to lubricate it.[2] 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.Seminal plasma of humans contains a complex range of organic and inorganic constituents.The seminal plasma provides a nutritive and protective medium for the spermatozoa during their journey through the female reproductive tract.

The Cowper's glands add a clear fluid.

What factors contribute to the solubility of LDL in blood plasma?
The factors that contribute to the solubility of LDL in blood plasma include the levels of lipids and proteins in the blood, as well as the pH and temperature of the plasma. Additionally, the presence of certain enzymes and other molecules can also affect the solubility of LDL.
