NCT06863337

Brief Summary

No studies have been seen on glucose variation during medication for assisted reproduction. The aim of this study is to continuously observe glucose variation during assisted reproduction treatment using continuous glucose monitoring (CGM), and to further explore whether glucose variation will affect the outcomes related to assisted reproduction.

Study Arms (1)

wearing continuous glucose monitorings

EXPERIMENTAL

Patients will wear two FreeStyle Libre Pro Flash CGM (Abbott Diabetes Care, Alameda, CA, USA) to ensure continuous tracking of blood glucose levels at key time points throughout the ovarian stimulation.

Device: CGM

Interventions

CGMDEVICE

Each patient will participate in the group only once and wear two FreeStyle Libre Pro Flash CGM (Abbott Diabetes Care, Alameda, CA, USA), which record glucose readings for up to 14 days. Following the initial consultation and before initiating the ovulation induction protocol, the first CGM sensor will be placed to collect baseline data. Upon entering the ovulation induction cycle, patients will return to the hospital on the 2nd or 3rd day of menstruation, at which point the first CGM sensor will be removed, and the second sensor will be applied. This second sensor will be removed after 14 days. In summary, this protocol ensures continuous tracking of blood glucose levels at key time points throughout the ovarian stimulation.
