Pregnancy cannot occur without healthy eggs and sperm. It's just that many women do not pay attention to the quality of the egg, even though the damaged egg can be one of the causes of women having difficulty getting pregnant.
The egg consists of various layers which will be useful for fetal formation and development. These layers include, the zone of pellucida or the outer layer that serves to protect the egg during its development, cytoplasm which is a proteinous area as a nutrient for the egg, and the nucleus or cell nucleus which will later function as carriers of genetic material forming new individuals. However, not all eggs can be formed perfectly.
Egg cell damage
One of the disorders that occurs when the egg is damaged is a chromosomal abnormality that is in the cell nucleus. This damage results in a pregnancy without an embryo, or a pregnancy without a fetal candidate. Normally, when a woman is pregnant, the fertilized egg will stick to the uterine wall. When entering the womb about 6 weeks, the embryo has begun to grow together with the uterus as a developing fetus. But this does not happen to damaged eggs, only the uterus will continue to grow. This condition is also called the term pregnancy empty or blighted ovum. This type of pregnancy usually has signs similar to normal pregnancy, such as breast pain, nausea, vomiting, not having menstruation, and a positive pregnancy test. Without the fetus, the growth of the placenta will also not be maximal and eventually stop. At this time the pregnancy hormone levels will decrease dramatically and cause signs of miscarriage, such as bleeding from the vagina, spotting of blood, and cramps in the abdomen. Miscarriage in pregnancy without an embryo can not be prevented and is not the fault of the mother of course. Women who have experienced egg damage may not experience it again, and will successfully become pregnant later in life. However, if a miscarriage occurs repeatedly, you should do further examination to the obstetrician to find out the real cause.Default Genetic Problems
Genetic mutations are changes in genes that occur in the mother's egg cell or father's sperm cell. At the time of conception, the egg and sperm cells combine to form the fetus in the womb. But, because of a mutation in one of the genes in the egg cell or sperm cell, the prospective baby formed has a disorder or disability. This condition is also known as hereditary genetic mutation because it is passed on to the next generation. This mutation can cause several diseases, including cancer in newborns, such as retinoblastoma tumors or Wilms tumors.Abnormalities in Egg Cell Development
Mola pregnancy or grape pregnancy can not be ascertained the cause. However, abnormalities in the egg cell allegedly involved in causing this pregnancy. The egg and sperm contain chromosomes that carry DNA from both mother and father. When the two cells unite in fertilization, the egg and sperm cell each contribute half of the complete amount of DNA to the prospective baby to be born. But if there is an abnormality in the number of chromosomes, both more or less, there will be a molar pregnancy or a pregnancy of wine. Based on the type, molar pregnancies can be grouped into two, namely:Partial molar pregnancy
This pregnancy occurs when the fetus is formed but cannot grow and develop perfectly or survive to be a baby.
Complete mola pregnancy
There are abnormal cells that form in the uterus, and there is no development or formation of the fetus at all.
