Cryopreservation of Ova, Sperm and Embryo

Risks Superovulation Stimulates Egg Development Ovarian Hyperstimulation Syndrome (OHSS) -could cause ovarian enlargement, fluid in the abdomen, difficulty breathing, kidney failure and blood clots which in rare and extreme circumstances can even result in death. -common side effects include bloating, enlarged ovaries, nausea, diarrhea, and tender breasts.

Bypassing the natural method of conception. The creation of life in the laboratory. Fertilization of more embryos than will be needed. Discarding of excess embryos. Unnatural environment for embryos. Use of untested technology. Not affordable for many. Misallocation of medical resources. Ethics m/files/u818/babies- money_ jpg

Creation of embryos, then freezing them, and keeping them "in limbo" Exposure of embryos to unnatural substances Destruction of embryos in research Potential to create embryos for medical purposes Potential to select embryos (Preimplantation Genetic Diagnosis)  My Sister’s Keeper Potential to modify embryos (designer babies) nal/designer_baby_2.jpg

Facilitation of the idea that embryos are commodities. Financial rewards for IVF doctors dissuade them from recommending other methods to couples. Infertility is treated as a disease and not as a symptom of underlying medical problems.
