The global sonohysterography catheters market is projected to grow significantly between 2025 and 2035. Sonohysterography, also known as saline infusion sonography, involves using specialized catheters to infuse sterile fluid into the uterine cavity. This enhances the visualization of the endometrial lining during transvaginal ultrasound examinations, making it a key tool for evaluating infertility, abnormal uterine bleeding, fibroids, polyps, and other intrauterine anomalies. Expected to grow at a compound annual growth rate of 5.3% during the forecast period, the market value is set to reach USD 24.8 million by 2035. The procedure is typically performed before initiating assisted reproductive technologies (ART) such as in vitro fertilization (IVF) to detect potential intrauterine pathologies that may hinder embryo implantation.
