ABSTRACT

IVM is improved by hCG priming17; hCG priming does not seem to increase the number of oocytes retrieved, but it reduces the time needed for IVM18. The dose of hCG was studied in a prospective, randomized, double blind study by our group and increasing the dose did not give any benefit in any of the outcomes, therefore current evidence suggests a benefit from 10 000 IU hCG administered 36 h before the collection19.
