Fertil Steril. 2007 Apr;87(4):991-4. doi: 10.1016/j.fertnstert.2006.08.087.

Abstract

In IVF cycles using a GnRH agonist down-regulation short protocol, when the concentration of P on day 4 of stimulation was >3 ng/mL, patients experienced a significantly reduced implantation rate (14.1%), pregnancy rate (24.6%), and ongoing pregnancy rate (20.0%), with an elevated early miscarriage rate (18.8%).
