OHSS triggers

Ovarian hyperstimulation syndrome (OHSS) does not occur in all women because there is strict medical monitoring to prevent it. All women should have regular ultrasound checks to monitor the growth of their ovarian follicles.

Ovarian stimulation for assisted reproduction treatment lasts approximately 10-12 days. During this period of time it will be necessary for the woman to administer gonadotropins and GnRh analogues to promote the growth of multiple follicles. In addition, 36 hours before the ovarian puncture takes place, the woman will be administered the hormone hCG which is responsible for inducing ovulation.

It should be noted that the hCG hormone increases the permeability of the blood vessels and therefore causes the excessive release of fluids out of the bloodstream. For this reason, OHSS usually occurs 3 days after the ovarian follicles are punctured.
