An Observational Study to Evaluate Efficacy, Safety and Clinical Outcomes of Currently Used Pharmaceutical Therapies for Controlled Ovarian Stimulation in Assisted Reproductive Techniques (ESCORT)

The objective of this observational program is to evaluate the efficacy and safety of the gonadotropins used for COS in ART. The clinical use of the various progesterone preparations will also be monitored and registered. All medications will be used according to normal clinical practice, as described in the Summary of Product Characteristics (SmPC). From the start of the program cycles data will be collected prospectively for 12 months and also a substantial amount of cycles will be analyzed retrospectively for the previous 6 months. Data will be collected from all subjects stimulated by follicle stimulating hormone (FSH), with or without down regulation and exogenous lutenizing hormone (LH) supplementation, and final follicular maturation triggered by human chorionic gonadotropin (hCG) and luteal phase support by any means for COS in ART and intracytosolic sperm injection (ICSI). All the medications should be used according to usual clinical practice. Data related to pretreatment (basal examination, history of infertility, LH suppression), stimulation (gonadotropin use, concomitant medications, luteal phase supplementation, ovulation triggering, cycle cancellation, fertilization methods), safety aspects and clinical outcome will be captured.
