Introduction: Biochemical follow up of the ovarian function after ovarian stimulation is restricted to the measurement of serum oestradiol and progesterone. We aim to investigate the entire ovarian steroidognesis after ovarian stimulation.Materials and methods: 50 women (26 IVF and 24 ICSI) who underwent AMP induction (based on rFSH stimulation after GnRH agonist or antagonist) for the same cause of infertility were retrospectively involved and compared ...

Introduction: Biological diagnosis of Cushing syndrome relies on three parameters: 24 hours-free urinary cortisol; serum cortisol after 1 mg dexamethasone suppression test; late-night serum or salivary cortisol. These tests allow the diagnosis of cortisol excess but do not help in etiological diagnosis, particularly in the distinction between pseudo-Cushing and ACTH-dependent Cushing syndrome, which is often challenging. The aim of this study was to evaluate the performances o...

Introduction: The gold standard for insulinoma diagnosis is still 72-hours fasting trial with the aim to trigger Whipple’s triad. In this context, biological diagnosis of endogenous hyperinsulinism relies on the occurrence of a hypoglycemia, concomitant with inadequate high insulin and C-peptide levels. However, diagnostic cut-offs are not consensual among the different learned societies (Endocrine Society 2009, NANETS 2010, ENETS 2012). The objective of this wor...
