Design outcomes

Primary

Measure	Time frame
Secondary Objective: The secondary end-points are the OHSS rate, the mid-luteal progesterone level and the correlation between mid-luteal progesterone levels and the reproductive outcome.;Primary end point(s): The primary end-point will be the reproductive outcome defined as the ongoing pregnancy rate per patient at 10th week of gestation. ;Timepoint(s) of evaluation of this end point: 10th week of gestation. ;Main Objective: The objective of this pilot RCT is to explore the exogenous progesterone free luteal phase after GnRHa trigger in a population of IVF patients at risk of OHSS development, characterized by the development of 14-25 follicles =11 mm on the day of triggering of final follicular maturation.	—
