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.

The components and contributions of semen are as follows: Approximately 200- to 500-million spermatozoa (also called sperm or spermatozoans), produced in the testes, are released per ejaculation.

Semen quality is a measure of the ability of semen to accomplish fertilization. It is the sperm in the semen that is the fertile component, and therefore semen quality involves both sperm quantity and sperm quality.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.In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or "swim".Semen is produced and originates from the seminal vesicle, which is located in the pelvis.papua new guinea girls fuck in port moresbyelizabeth liz dage smejkal in porn slut iowa slut21ji no onna newscaster katsuragi miki ep 0145 years amma sex videos malayali48office sex japan japanese secretary fucked in officeafghn sex vdeoalexis breeze shorty macallie haze hd masterbationamadahy forced to eat condom cumanal banjarmaainanimal fuck human beinganimal jerk offanonymox porn indonesial ariel cut tarianton bernardoanupamaapek tudungarab video Disclaimer: has a zero-tolerance policy against illegal pornography.We do not own, produce or host the videos displayed on this website.
