Daytime Profile of Salivary Progesterone

Daytime Profile of Salivary Progesterone During the Mid-luteal Phase of IVF and FET Cycles

The aim of this study is to perform a 12-hour profile of free saliva progesterone during the luteal phase after fresh and frozen embryo transfer. If progesterone levels in saliva samples show a constant level during daytime, this non-invasive measurement can be used in future ART patients with insufficient progesterone levels who might benefit from additional exogenous progesterone supplementation.

Inclusion Criteria:

• One or two good quality embryos for transfer on day 5.
