Cervix - Anatomy & Function

Cervix - Anatomy & Function

The cervix is the lower most part of the uterus and is made up of strong muscles. It also provides support to the uterus due to attachment of muscles from the pelvic bone. The cervix protrudes and opens through a canal into the vagina.

The function of the cervix is to allow the flow of menstrual blood from the uterus into the vagina, and direct the sperms into the uterus during intercourse.

The opening of the cervical canal is normally very narrow. However under the influence of the body hormones and the pressure from the fetal head, this opening widens to about 4 inches (10 cm.) during labor, to allow the birth of a baby.

If the opening is loose, as observed in some women, it can lead to miscarriages during pregnancy.

Cervical ripening procedure consists of softening, dilation and shortening of the cervical canal in order to push the baby out without any obstruction.

Cervirax is considered to be effective before any contact with semen, but if somebody is using coitus interruptus method of contraception is it of any use or not????

The vaccines Gardasil and Cervarix won't reduce cancer incidence or deaths. They will divert hundreds of billions of health care dollars to the coffers of pharmaceutical companies.

HPV infections, advertised to be the cause of cervical cancer, are slow and handled by our immune systems in over 90% according to the CDC/FDA/American Cancer Society

Women who don't clear HPV infection have immune problems caused by nutritional deficiencies, toxic exposure, toxin ingestion or genetics.

If an immune system can't clear an HPV infection no vaccine can help. Vaccines are passive targets and can't fix an immune system unable to identify or destroy HPV

HPV is controlled by intracellular immune response. Vaccine stimulate the humoral, antibody, response. Antibodies fight bloodborne infections and will not appreciably affect the rate of cervical HPV infections and CANNOT combat an active HPV infection

This will be proved in 20 years when vaccines are shown to have failed

guest

You're correct in stating that the vaccines will not combat those already infected. However, they have been proven to prevent infection of the HPV strains 6,11,16, and 18. Women don't have to have an "immune problem" caused by toxins, etc. to not clear the infection.I suggest you check your facts before posting such erroneous statements.

guest

I made no errors. Over 90% of us clear all HPV infection without drugs doctors or vaccines [FDA], a properly functioning immune system doing it's job. Chronic infection is caused by an immune system problem as I described

Gardasil has NOT been proven to prevent HPV infection, except by conflicted Merck research

A humoral response cannot prevent HPV infection of epithelial tissue, but cell mediated response can. Vaccines to provoke a cell mediated response are being developed. Until then Merck will be defrauding its customers with your help

Gardasil is the largest medical fraud in history perpetrated by Merck, maker of Vioxx and Pargluva, their two previous medical frauds.

Less than 1% of women chronically infected with HPV develop cervical cancer. This is not a cause and effect relationship. Read the Markovics' (oncologists) opinion that HPV and cervical cancer are together merely by coincidence, due to HPV being common and cervical cancer being rare.
