Primary prevention
Prevention of DMD and other inherited muscular dystrophies is only possible when it is suspected. DNA analysis can be performed on fetal material obtained via amniocentesis. If it is an option, abortion can then be considered. In-vitro fertilization with preimplantation diagnosis can also prevent DMD. Preimplantation genetic diagnosis is 90% accurate for in-vitro fertilization. Subsequent amniocentesis done from 10 weeks' to preferably 14-16 weeks' gestation can provide further assurance of the health of the fetus. If a pregnant woman who is known to be a carrier of the DMD gene does not wish to have amniocentesis, her male offspring have a 50% chance of being affected by DMD, and female offspring have a 50% chance of being carriers.
The American College of Obstetricians and Gynecologists recommends that carrier screening for spinal muscular atrophy is offered to all women who are considering pregnancy or are currently pregnant.[16][20]
