Saline Infusion Sonography (SIS) is an advanced ultrasound technique that provides clear images of the inside of the uterus. Also known as sonohysterography, SIS involves injecting a small amount of saline solution (salt solution) into the uterus, allowing detailed visualisation of the endometrial lining on an ultrasound scan. This procedure is highly effective for diagnosing uterine abnormalities, such as fibroids, polyps, and adhesions, as well as for evaluating the endometrial cavity for conditions like endometrial cancer or hyperplasia. The best IVF and Fertility Center in Chennai offers SIS as part of technological and diagnostic advancement. 

SIS is typically performed under local anaesthesia, making it a safe and minimally invasive test that uses sound waves and computer-generated images without any radiation exposure. In fertility treatments, SIS can be aligned with the timing of egg retrieval for the female partner, providing valuable insights into uterine health.
