In standard IVF stimulation cycle,human chorionic gonadotropin (hCG) is usually used at the end of controlled ovarian hyperstimulation (COH) as a surrogate to only the luteinizing hormone (LH) surge. Yet, the last dose of follicle stimulating hormone (FSH) is usually given between 12-24 hours before the hCG triggering dose.One protocol used at the investigators unit, after a cycle with low proportion of mature oocytes per number oocytes retrieved, is triggering with high dose hCG (500 mcg)-38 hours prior to oocyte aspiration.
Lately, new researches showed that dual triggering of final oocyte maturation with a combination of GnRH- agonist and hCG, could improve the live-birth rate of normal responders undergoing the GnRH-antagonist COH protocol
Another treatment option is high dose hCG. Only few case reports have described the use of high dose hCG after aspiration of non mature oocytes at a previous cycle. At the investigators IVF unit, patients with previous history of high percentage of immature oocytes retrieved, are triggered at the following cycle, either with double trigger or with high dose of hCG decided by the physician consulting the patient. It is still not known with which way of triggering more mature oocytes is retrieved.
The aim of this study is to perform a prospective randomized controlled study in patients with low proportion of mature-MII oocytes oocytes (<75%) per number oocytes retrieved, despite normal response to controlled ovarian hyperstimulation ( COH ) comparing cycles triggered with high dose hCG to those triggered with hCG+GnRH agonist.
|Condition or disease||Intervention/treatment||Phase|
|Infertility||Drug: GnRH agonist 0.2 mg + hCG 250 mcg Drug: high dose hCG 500 mcg||Not Applicable|
Patients will be prospectively randomized into two groups. The randomization will be organized through the computer. The hCG group- will be triggered for final follicular maturation with high dose hCG (500 mcg)-38 hours prior to oocyte aspiration, and the Double trigger Group- will receive gonadotropin-releasing hormone (GnRH) agonist (Decapeptyl 0.2mg) 40 hours prior to oocyte aspiration and hCG (250mcg) 34 hours prior to the oocyte aspiration. All patients will be supplemented with the same progesterone preparation( Crinone gel 8% once a day) for luteal support. Women that suffer from vaginal spotting or vaginal bleeding during the luteal phase will receive supplementation of Geston 50MG intramuscular once every 2 days.
At the day of oocyte aspiration, blood will be drawn for serum LH, FSH, estrogen (E2) and progesterone. Moreover, clear follicular fluid will be collected and tested for LH, FSH, E2 and progesterone levels.
