The effect of luteal support with human chorionic gonadotrophin or progesterone on the daily progesterone profile after different types of ovarian stimulation.
Attempts have been made to increase the low pregnancy rate in in-vitro fertilization (IVF) cycles by luteal phase support with progesterone or human chorionic gonadotrophin (HCG). Previously, this practice has been inconsistent and the results unclear. The detailed effect of support on the progesterone profile in the luteal phase was assessed by daily salivary progesterone measurements in non-conception IVF cycles. The comparison of HCG and progesterone support in two different stimulation protocols showed that the profile of luteal progesterone concentrations was similar in control cycles and those supported with a vaginal progesterone suppository, showing an early decrease by the fourth luteal day. In cycles supported with multiple doses of HCG, the progesterone profile was normal but slightly increased up to the 9th luteal day subsequently falling to basal levels by the fourteenth luteal day.
