A 30-year-old woman who has tried for a year to become pregnant presents to the nurse practitioner, who diagnoses cervical stenosis as the probable cause of her infertility. Which is the most appropriate treatment?

Choice A reason: IUD insertion is a contraceptive method and would not address cervical stenosis or aid fertility. Choice B reason: Cervical dilation is the standard treatment for cervical stenosis to mechanically open the cervical canal and restore patency for conception. Choice C reason: Colposcopy is a diagnostic procedure for abnormal cervical findings, not a therapeutic intervention for stenosis. Choice D reason: LEEP (Loop Electrosurgical Excision Procedure) removes abnormal cervical tissue, not indicated for mechanical stenosis without dysplasia.
