What is internal pudendal artery?

The internal pudendal artery is a branch of the internal iliac artery, which is located in the pelvic region. It supplies blood to the perineum, which includes the external genitalia, anus, and pelvic floor muscles.

The internal pudendal artery runs along the ischial spine and then passes through the lesser sciatic foramen to reach the perineum. It gives off branches that supply blood to the external genitalia, including the clitoris or penis, labia majora, labia minora, and scrotum.

In addition to providing blood supply to the external genitalia, the internal pudendal artery also supplies blood to the anal canal and the muscles of the pelvic floor. It plays a crucial role in ensuring proper blood flow to these regions, which is essential for maintaining their normal function.

Injuries or blockages of the internal pudendal artery can lead to various health problems, including erectile dysfunction, pelvic pain, and incontinence. Therefore, it is important for healthcare providers to be aware of the anatomy and function of this important artery in order to properly diagnose and treat any potential issues.
