And I forgot to add this info that I found about chances of twins at the same site:
Chance of Multiples While on Clomid:
Twins - 1 in 10
Triplets - 1 in 200
Quadruplets - 1 in 333
Quintuplets - 1 in 1000
Overall you have a 1 in 6.5 chance of conceiving multiples while taking Clomid.
Chance of Multiples on HCG:
Twins - 20%
Triplets - 5%
Quadruplets - 2%
Quintuplets - 1%
S_xtuplets - 0.5%
You have a 20% chance of multiples while on Pergonal.
IVF:
About 25-30% of IVF pregnancies are multiple births, most of these twins.
1 in 4 IVF births results in twins, 1 in 22 IVF births results in triplets.
In a 1998 study of 2906 IVF multiple births, the breakdown was as follows:
Twins - 80.87%
Triplets - 17.48%
Quadruplets and Higher - 1.65%
In Canada, approximately 23% of IVF live birth confinements result in multiple births.
Twins born before June 1981, triplets born before June 1983, quads born before January 1984 and quints born before April 1985 will not be from IVF.
Out of all quadruplets born, 0.59% will have some identicals and be IVF sets as well. There are theories that the handling of the egg in ART technologies thins the protective covering of the egg and making it easier for the embryo to divide into twins. The other way identicals can happen is if the mother conceives identical twins spontaneously and also has IVF that results in a conception at the same time.
GIFT:
About 35% will result in multiples.
ZIFT:
About 35% will result in multiples.
