With fully normal results on both sides, open tubes, good ovarian reserve, normal hormones,
prolactin and
thyroid, and a normal semen analysis, the usual remaining factors are a uterine issue like polyps or mild endometriosis that a routine scan can miss, or genuinely unexplained infertility where testing finds no single cause.
Next Steps
A hysteroscopy or saline sonography looks more closely at the uterine cavity than a standard scan. After six years of trying, your fertility specialist will likely also discuss moving ahead with IUI or IVF.
Health Tips
Please discuss this with your fertility specialist in person. Which option suits you best depends on details only they can review together with you.
