Hello,
It is extremely unlikely that the adnexal lesion in your fallopian tubes is due to the CIN.
CIN is usually caused by HPV infection. HPV rarely, if ever, affects the tubes or the uterus in any way.
But adnexal lesions can be caused by other STDs like chlamydia or gonorrhea. Since HPV is also an STD, it is possible that you had picked up aother STD at the time which caused the lesion.
Whether your fertility has been affected or not can only be determined by other procedures like laparoscopy and hysterosalpingography. It will depend on whether the tube has got blocked in any way by the lesion and whether the other tube is also affected. Please consult a gynecologist for a thoroguh examination.
I hope this helps.
