Can you provide links to evidence for col increasing risk of perm labour and infertility?
I'm not sure about infertility which is why I put a ? beside it. I have heard it's a risk but I'm not sure if that is true. I think the colposcopy itself isn't much of a problem, but the biopsies and treatment that usually follows.
This is about loop/ cone biopsy
'Studies have shown that some treatments for CIN or stage 1A cervical cancer can lead to a small risk of complications in future pregnancies. Women who have had a cone biopsy are more likely to have their babies born before 37 weeks (preterm delivery). And the risk of having a baby that weighs less than 2.5kg (low birthweight) is higher. There may also be an increase in birth by Caesarean section for women who have had cone biopsy.'

This GP sums it up nicely for me
Screening tests are different. Because they aim to find disease you don't know about, the trade-off between benefits and harms tends to be more nuanced compared with tests done to investigate symptoms. Cervical screening does prevent deaths from cervical cancer. But to get that reduction, you have to follow up and/or treat all the women who have cell changes on their screening test. However, most cervical-cell changes found at screening will not lead to cervical cancer. The problem is we can't predict which will, so all need further monitoring or treatment. A study from Bristol in 2003 found that 1,000 women have to be screened for 35 years to prevent one death from cervical cancer; and to prevent that death, 80 women have to have further investigation, with 50 women having treatment to their cervices. Four out of five women found at screening to have "high-grade" changes in their cervix did not go on to develop invasive cancer.
Clearly, there is a benefit – but overall, it's small. That potential for good has to be weighed against the risks of treatment. It's known that having a cervical biopsy – which is done to get more information about the degree of abnormality – raises the risk of pre-term birth in later pregnancies. And the worry and anxiety that the results cause shouldn't be underestimated.
