Ovarian hyperstimulation syndrome (OHSS) is a serious iatrogenic complication of controlled ovarian stimulation of gonadotrophin-Stimulated ovarian cycles. It is theorized to manifest systemically as a result of vasoactive mediators like vascular endothelium growth factor (VEGF) being released from hyperstimulated ovaries. As a result, capillary permeability is increased which causes the extravasation of fluid from the intravascular compartment into the third space. The haemoconcentration which ensues results in complications such as hypercoagulability and reduced end organ perfusion.
Age between 18-38 years
Body mass index (calculated as weight in kilograms divided by the square of height in meters) < 30 kg/m2.
A long luteal protocol is used for ovarian stimulation.
Day 2 FSH <10 mIU/L and E2< 50 pg/ml
None
Parallel
Coasting
Procedure/SurgeryIn their ICSI cycle patients will continue their agonist treatment while stopping the human menopausal gonadotropin (hMG) injections for 1 to 3 days until drop of estradiol to a safe level to prevent OHSS. Early OHSS is assessed at day of embryo transfer and 7 days after this date. Late OHSS is assessed 14 days after embryo transfer.
Cabergoline
DrugCabergoline is used to treat different types of medical problems that occur when too much of the hormone prolactin is produced. It can be used to treat certain menstrual problems, fertility problems in men and women, and pituitary prolactinomas
Occurrence and severity of OHSS
The primary outcome of this study is the occurrence and severity of OHSS. OHSS was defined as abdominal pain and distention associated with nausea and vomiting and ovarian enlargement \> 8 cm. The severity of OHSS will be assessed (mild, moderate, severe, and clinical) according to the American Society for Reproductive Medicine guidelines
