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 is contraindicated in a patient seeking pregnancy. Choice B reason: Cervical dilation mechanically opens a stenotic cervical canal, restoring patency and allowing sperm to pass into the uterus, directly addressing infertility caused by cervical stenosis. Choice C reason: Colposcopy is a diagnostic procedure for cervical lesions, not a therapeutic intervention for infertility caused by stenosis. Choice D reason: LEEP (loop electrosurgical excision procedure) is used to remove abnormal cervical tissue for dysplasia treatment; it does not address cervical canal obstruction and is inappropriate for this scenario.
