Phase 3 |
Detailed Description
Patients less than 35years undergoing Intra Cytoplasmic Sperm Injection for infertility scheduled for gonadotropin releasing hormone agonist long protocol of ovarian stimulation.
All patient will receive combined oral contraceptive pills (Gynera, Schering-plow: plough) starting from day 5 of cycle that precedes the stimulated cycle .On day 21 of that cycle all patients will start to receive Gonadotrophin releasing hormone agonist in the form of (decapeptyl 0.1 sc daily and continued till the day of HCG administration).
To ensure that all patients are completely down regulated and desensitized ,trans-vaginal ultrasound will be performed at day 2-3 of menses of stimulated cycle to ensure endometrial thickness less than 5 mm and no ovarian cysts.Also serum E2 level is less than 50 pg/ml.
Then all patients will start to receive Gonadotrophin ( HMG) (Menogon, ferring pharmaceuticals, Germany) 225 IU (international unit) Intramuscular Injection daily,with continuous scheduled follow up of ovarian response by serial trans -vaginal US to assess follicular growth together will serial serum E2 starting from day 6 of cycle and onwards.With adjustments of gonadotropin dose and monitoring frequency based on patient response.
During follow up once the recruited patients fulfilling the inclusion criteria (serum E2 equal or more than 4000 pg/ml and /or 18 or more follicles of 11 mm diameter or more at any day of stimulation),they will be allocated randomly by computer generated cards and assigned by sealed envelopes by the treating doctor at the outpatient clinic.
Group A : will receive cabergoline 0.5 mg/day for 8 days, starting in the day of HCG (human chorionic gonadotropin ) injection.
Group B: will receive cabergoline 0.5 mg/day once the criteria of inclusion criteria is fulfilled and continued till the day of human chorionic gonadotropin (HCG ) trigger and continued 8 days more from day of trigger .

| Experimental: Early administration of Cabirgoline 0.5mg Cabergoline 0.5mg(Dostinex®, Pfizer Australia Pty Ltd ) once daily stared once patients fulfilling the inclusion criteria at any day of cycle and continued for 8 days post HCG trigger. |
Drug: Early Cabergoline 0.5mg
Cabergoline 0.5mg will be administrated once daily when E2 is more than 4000pg/ml and /or more than 18 follicles of 11mm diameter or more are encountered at any day of the controlled ovarian hyper-stimulation and before HCG trigger to be continued for 8days after HCG trigger.

Outcome Measures
Primary Outcome Measures
- Occurrence and severity of OHSS [2 to 4weeks after trigger]
either early or late OHSS (early OHSS is the occurrence within 9 days after OPU and occurrence after 10 days was classified as late OHSS.The severity of OHSS was graded according to the criteria of Navot et al. (1992). Moderate OHSS in particular is characterized by abdominal distension and discomfort, nausea±vomiting±diarrhoea, enlarged ovaries 5-12 cm and ultrasonographic evidence of ascites. Severe OHSS is characterized by variable ovarian enlargement; massive ascites±hydrothorax; breathing difficulties; haematocrit >45%; white blood cell count >15 000; oligouria; creatinine 1.0-1.5;liver dysfunction; and anasarca oedema.)
Secondary Outcome Measures
- Number of M|| oocytes. [maximum one day after ovum pick up]
- Fertilization rate. [16 to 19 hours after ICSI]
fertilization rate (the presence of two pronuclei (2PN) at the time of fertilization assessment, 16 to 19 hours after ICSI),
- Clinical Pregnancy rate [2 to 4 weeks after positive pregnancy test]
Clinical pregnancy was considered to be the presence of a gestational sac with fetal heart activity.
- implantation rate [2 to 4 weeks after positive pregnancy test]
implantation rate( the percentage of embryos which successfully undergo implantation compared to the number of embryos transferred)
