I am 31 old female transfered to IVF -ICSI due to male factor infertility(Hypogonadtrophic Hypogonadism).My fertility chek up was fine with no apperent problem.MYfirst IVFcycle with two emberyo transfer resulted in one baby.My seconed IVF cycle with 8 emberyos all of grade A and one of GRADE B resulted in one no implantation,seconed frozen transfer with early abortion and third frozen transfer with missed abortion.IS genetic problem behined our failure.DO we need the next time preimplantation genetic diagnosis before emberyo transfer? Does increasing the sperm count with drugs of my husbened gives better results, is that true?
