Early Short Stimulation Modified Natural Cycle IVF With GnRH Agonist Trigger and In Vitro Maturation in a Woman with Polycystic Ovary Syndrome: A Case Report.
Gonadotropin-releasing hormone agonist (GnRHa) triggering of final oocyte maturation has been used successfully in GnRH antagonist IVF cycles. It has not been used to date in cycles in which immature oocytes are matured in vitro.



We report here for the first time that GnRHa triggering in a variation on the modified natural IVF cycle can be used as a strategy in the treatment of infertility secondary to polycystic ovary syndrome. In this approach, follicles were stimulated with gonadotropins for three to five days when they were small, and triggering of ovulation occurred when the largest follicles were 10 to 12 mm in diameter. This was followed by retrieval of many immature oocytes that were matured in vitro and subsequently developed to form blastocysts that resulted in a live birth.



This is the first human evidence that GnRHa triggering of ovulation can be used successfully when the aim is in vitro maturation of oocytes.
