Luteal phase support in assisted reproduction cycles. Daya S, Gunby JL. Department of Obstetrics & Gynecology, Clinical Epidemiology & Biostatistics, 2407 Carrington Place, Oakville, Ontario, Canada, L6J 7R6. Update of: Cochrane Database Syst Rev. 2004;(3):CD004830. BACKGROUND: The aspiration of the granulosa cells that surround the oocyte and the use of gonadotropin releasing hormone agonists (GnRHa) during assisted reproduction technology (ART) treatment can interfere with the production, during the luteal phase, of progesterone, which is necessary for successful implantation of the embryo. Providing hormonal supplementation during the luteal phase with either progesterone itself, or human chorionic gonadotropin (hCG), which stimulates progesterone production, may improve implantation and, thus, pregnancy rates. OBJECTIVES: To determine (1) if luteal phase support after assisted reproduction increases the pregnancy rate, (2) the optimal hormone for luteal phase support, ie hCG, progesterone, or a combination of both, and (3) the optimal route of progesterone administration. SEARCH STRATEGY: We searched the Cochrane Menstrual Disorders & Subfertility Group trials register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1971 to Dec 2003), EMBASE (1985 to Dec 2003). We handsearched reference lists of relevant articles were scanned, and abstract books from scientific meetings up to December 2003. SELECTION CRITERIA: Randomized controlled trials of <b>...</b>
