Miscarriage or abortion is the final event of a failed pregnancy where the embryo or fetus does not grow and survive. Usually this occurs before 20 weeks gestation. Bleeding or blood spotting in the first trimester of pregnancy is an early sign of miscarriage for most women.

Normally, when the sperm fertilize the egg, then that embryo is formed. Embryo cell divides genetic characteristics of her father and mother. Nevertheless, some specific genetic abnormalities that can cause miscarriage.

Some experts believe that aneuploidy, an abnormal number of chromosomes, can lead to failure of embryo implanted in the uterine wall. In some cases, aneuploidy embryos can undergo normal growing process but only to a certain point.

"In both cases, whether the embryo aneuploidy can attach itself to the lining of the uterus or not, a miscarriage may still occur," said Dr. Ivan Heredia, Gynaecology and Clinical Director Morula IVF Jakarta.

Approximately 30-80 percent of these cases will end in fetal death or even stillbirth. Even so, there is some abnormal fetus can continue to grow until the end of pregnancy and produce a baby with major disability.

"The problem with this chromosome occurs at random and had nothing to do with something that is done by both parents," said the doctor who handles many of these infertility problems.

How the way we look at this event? Miscarriage is an undesirable thing to any woman. However, the good news is there is a chance again for a subsequent pregnancy does not always end in miscarriage again.

"Although environmental factors and lifestyle of the mother has little effect on miscarriage, there are more important things to be aware of the other. A stressful lifestyle is not always increase the risk of women experiencing miscarriage. However, smoking, alcohol consumption, and obesity may increase the risk of miscarriage, "explained Dr Ivan.

Furthermore, Dr Ivan explained, in addition to the custom, the process of digestion or chemical teratogens can cause birth defects which may lead to miscarriage. In the same way, some infections such as Toxoplasma and Listeria have teratogenic effects.
