Recombinant human chorionic gonadotropin versus purified human chorionic gonadotropin trigger for In vitro Fertilization intracytoplasmic sperm injection cycle

The recombinant human luteinizing hormone or human chorionic gonadotropin (hCG) has substantially taken over the product which was formulated from the urine of pregnant women. In addition to this, a number of randomized controlled trials have been conducted comparing the significance of recombinant hCG (rHCG) with urinary hCG in assisted reproduction. Nevertheless, the present study has collected secondary information based on the nature of the chosen research area. The acquired data and information have been analyzed using content analysis technique to review the methodology and findings of the selected research articles. With the use of rHCG as well as purified hCG, the serum level was equivalent at day 5 among women underwent intracytoplasmic sperm injection (ICSI) but this level abnormally increased among those injected with rHCG thus, minimizing the rate of pregnancy. It has been concluded that purified hCG trigger plays a more efficient role in inducing oocyte maturation and increasing the rate of pregnancy among women undergoing in vitro fertilization ICSI cycle in comparison to rHCG trigger.
