N98.1: Hyperstimulation of ovaries

You received hormone treatment as part of artificial insemination. This has caused problems.

You can receive hormones before artificial insemination. These hormones are supposed to help egg cells to mature in the ovaries, among other things.

Your body reacted too strongly to the hormones.

The body reacting too strongly to the hormones causes an increased amount of fluid to build up around the egg cells. This can cause the ovaries to swell up. The blood vessels in the body can also become more permeable. This can cause an increased amount of fluid to flow from the blood vessels into the tissue and body cavities. This may result in major organs such as the kidneys not being supplied with enough blood.

This overreaction of the body can cause various symptoms. This can cause things like nausea and vomiting as well as abdominal pain. The kidneys not being supplied with enough blood can lead to a person not excreting enough urine. Other organs can also be affected. In that case, you may be seriously ill.
