E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective of this study will be to assess the efficacy of natural progesterone at a daily dose of 25 mg in restoring a normal luteal phase. The primary end-point will be the ongoing pregnancy rate. |
Valutare l’efficacia di una somministrazione giornaliera di 25mg/bid di progesterone naturale nel ristabilire la normale fase luteale, quindi la maggiore percentuale di gravidanze.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives will be the rate of endometrial biopsy showing an in phase endometrium after 3 months of treatment. The length of the luteal phase of the menstrual cycle after treatment will also be assessed and compared with the initial duration (from LH peak to onset of menstruation).
|
L’obbiettivo secondario sarà la percentuale di biopsie dell’endometrio che mostreranno di essere in fase dopo tre mesi di trattamento. Sarà valutata anche la lunghezza del ciclo mestruale dopo il trattamento paragonata con la durata iniziale (dal picco di LH all’arrivo della mestruazione).
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
