Monochorionic-diamniotic twins resulting from the transfer of a single embryo in a woman with decreased egg reserve: A case report
Purpose: To report the first case of dentical twins born to a woman with decreased oocyte reserve having a single embryo transfer (ET). Methods: Minimal stimulation with gonadotropins (no more than 75 IU/day of human menopausal gonadotropins) for a few days followed by oocyte retrieval. Results: The woman, aged 37, had seven in vitro fertilization (IVF) cycles with minimal or no gonadotropin stimulation. An embryo was formed in four of seven retrieval cycles (57.1 %). She conceived on her seventh cycle and delivered monochorionic diamniotic twins. This pregnancy was achieved with the transfer of six embryos over eight cycles (counting a hyperstimulated cycle performed previously in another IVF center following traditional controlled ovarian hyperstimulation). Conclusions: This case demonstrates that successful pregnancies are possible with single embryo transfers in women with decreased egg reserve including identical twins.
