Identical (monozygotic) twins occur once one egg is inseminated by one sperm and divides into two embryos. This split can occur at any stage up to nine days after fertilization and its timing is important to the way the placenta(s) and amnionic sac(s) are formed.
Due to the cacophonous of the fertilized ovum early in pregnancy, mothers aren’t at the start aware they have conceived with twins. It’s not until twins may be suspected because of the intensity of pregnancy symptoms, or if they have been diagnosed through ultrasound, that a couple might recognize they’re expecting twins.
The odds of getting twins are way greater than for the other type of multiple births. Around ninetieth of all multiples are created up of twins; the remaining 100 percent is with triplets, quadruplets and very occasionally quintuplets and more. In recent years there has been an enormous increase within the numbers of twins being born. This can be thanks to advancing maternal age, assisted reproduction technology, yet because the use of fertility medication. Significantly, higher neonatal care has meant that premature twins have a much better probability of survival than ever before.
There are 2 types of twins – identical or monozygotic (one egg), and non-identical or dizygotic (two eggs) twins. different names for identical twins are non-fraternal twins, and non-identical twins are typically referred to as fraternal twins.
