Brief Summary

Sleep is a critical component of daily life that significantly influences health and well-being. Despite the integral role sleep plays in life, its effect on women's reproductive health, and its subsequent impact on fertility, is largely understudied. The purpose of the SLEEP Study is to investigate the link between sleep and fertility. Participants will use a wireless wearable device mounted on the finger to measure sleep in the weeks preceding and following an embryo transfer during treatment with in vitro fertilization. The investigators hope that these findings will inform future therapies that improve sleep and fertility outcomes.

Outcome Measures

Primary Outcomes (1)

  • Effect of sleep on IVF outcomes

    To elucidate a potential correlation between average total sleep time and other sleep parameters (sleep efficiency, wake after sleep onset, and sleep stages) during the pre- and post-embryo transfer windows on rates of implantation, clinical pregnancy, ongoing pregnancy, and miscarriage.

    Sleep parameters will be measured on a daily basis

Secondary Outcomes (3)

  • Effect of anxiety on sleep parameters

    Anxiety will be assessed at baseline with GAD-7

  • Effect of depression on sleep parameters

    Depressive symptoms will be assessed at baseline with PHQ-9

  • Effect of frozen embryo transfer protocol type on sleep parameters and pregnancy outcomes

    Sleep parameters will be measured on a daily basis. Pregnancy outcomes will be measured at time of pregnancy testing, and if positive up to 8-10 weeks of gestation

Study Arms (1)

Euploid embryo transfer group

Participants will wear the Oura Ring continuously for data collection starting in the month prior to their embryo transfer date. They will wear the Oura Ring throughout the preparation, embryo transfer, and post-transfer until either a negative pregnancy test or, if positive, until 8 weeks gestation. The study time for each participant will thus extend from either 5 weeks for negative pregnancy tests, to 10 weeks for normally continuing pregnancies.

Device: Oura ring

Interventions

Oura ringDEVICE

Patient will wear Oura ring before and after embryo transfer. They will be blinded to sleep data during this period. Thus the intervention of wearing the ring to track sleep will not affect outcomes, but rather track the outcome of sleep.

Euploid embryo transfer group
