Thank you so much for sharing such insightful information. However it could have been better if you shed light on its pros and cons. More of so the cons. Unpleasant side effects are frequently experienced such as headaches, cramping and bloating, mood swings, temporary weight gain, nausea and vomiting, bruising and pain at the site of the injections, and tender breasts. An adverse reaction to the general anesthesia, or an infection which is severe or left untreated, could also cause death. With egg donation, there is the possibility that the ovary could twist and cut off its own blood supply (torsion). This occurrence could cause the loss of an ovary. If ovarian hyper stimulation becomes uncontrollable and excessive, one or both ovaries could need to be removed. Although further studies are needed, medical reports indicate links between fertility medications and ovarian and breast cancer.
