Superfecundation and superfetation describe two different mechanisms by which twins can be conceived. Superfecundation occurs when two different eggs are fertilized from separate acts of intercourse close together. Superfetation is the fertilization of eggs released in different menstrual cycles. In some cases of twin pregnancies, if one fetus dies early on, it can become compressed and flattened between membranes in a state called a foetus papyraceus or compressus. Sometimes known as "vanishing twins", serial ultrasounds may reveal the early death of one twin with the pregnancy continuing successfully with the surviving twin.

11. SUPERFECUNDATION:
It is the fertilization of the two different ova released in the same
cycle by separate act of the coitus within short period of time.
SUPERFETATION:
It is the fertilization of the two ova released in the different
menstrual cycles.
FOETUS PAPYRACEOUS
OR COMPRESSUS:
It is a state which occurs if one of the fetus dies early .The dead
fetus is compressed and flattened between membrane of the living
fetus and the uterine wall. It may occur in both the twins but more
commonly occurs in uniovular twins.
VANISHING TWINS:
Serial USG in multiple pregnancy since early gestation reveals
occasional death of one fetus and continuation of pregnancy with
the surviving one. The dead fetus if within 14 weeks simply
vanishes by reabsorption.
