It is a device placed in the uterus and is the world's most widely used method of reversible birth control. It remains in place the entire time pregnancy is not desired. Depending on the type, a single IUD is approved for 5 to 10 years use. There are two broad categories of intrauterine devices: copper-based devices, and those that work by releasing a progestogen.

The intrauterine insemination catheter is a single-use, disposable device for use in intrauterine artificial insemination and saline ultrasound infusion. The catheter has two opposing smooth side eyes and a rounded, smooth, closed distal tip. It has an overall length of 18cm and consists of a flexible-end inner catheter and a detachable outer sheath, which is attached to the inner catheter by a Luer lock. The inner catheter is 16 gauge with a uniform lumen throughout its length. When the outer sheath Luer is attached to the hub of the catheter, the inner catheter protrudes from the outer sheath by 5cm. The outer sheath has a series of 1cm graduations at the distal end.
