What are the associated risks of egg donation?

Some egg donors may experience side effects in relation to the egg donation procedure, but these are generally short-term and to be expected during and immediately after the ovarian stimulation and egg retrieval. The most common side effects are similar to PMS-symptoms, and include headaches, mood swings, bloating, nausea, cramping, hot flashes, breast tenderness and/or temporary stinging where the injection was administered.

Ovarian Hyperstimulation Syndrome (OHSS) may occur in less than 1% of stimulated cycles, and even more rare is the risk of Ovarian Torsion.
