Ovarian hyperstimulation syndrome belongs to the most serious complications of controlled ovarian hyperstimulation.
However, the present management of the stimulation allows lowering of its occurrence to a minimum, except some patients
with rare genotype, in whom the hyperstimulation syndrome is possible also in spontaneous gravidity. Also here
we have workplaces with the possibility to apply some special approaches. Besides basic preventive measures also use
of short-term stimulation protocols with the antagonist GnRH is possible, as well as the application of cryptoprogram
with vitrification of the oocytes and embryos. Not administration of HCG and triggering the ovulation with the antagonist
GnRH does not lower the successfulness of the treatment, more likely contrarily, the transfer of de-frosted blastocyte
into prepared endometrium allows comparable successfulness as the transfer of fresh embryos. Perinatal results also
seem to be better.
