Integrating salpingoscopy and immunohistochemistry to improve tubal infertility diagnosis: a retrospective cohort study

Integrating salpingoscopic visualization with IHC profiling enhances detection of subtle mucosal and molecular abnormalities that are frequently missed by conventional diagnostic approaches. This combined modality offers superior prognostic accuracy and may guide personalized surgical and assisted reproductive treatment strategies. Ethical approval was obtained from the Ethics Committee of the Kazakhstan Medical University «KSPH» (IRB-64-2023).
