What the cervix does
- Allows the flow of blood from the uterus during menstruation (periods).
- Helps to direct sperm into the uterus for conception.
- Secretes mucous which helps to boost fertility.
- Prevents bacteria and infections from entering the uterus and fallopian tubes.
- Holds a plug of mucous in place during pregnancy. This creates a barrier to stop infections tracking up into the uterus and affecting the baby.
- Dilates to a maximum of 10 centimetres during labour. This allows the baby’s head (or bottom) to be born.
- May play a role in sexual pleasure. Exactly how remains a bit of a mystery, but some women claim they are able to achieve a cervical orgasm because of the high concentration of nerve endings in the cervix.
- Gives us an opportunity to buy new underwear at least once a year when our pap smear is due!
