Outcome Measures

Primary Outcomes (1)

  • Good birth outcome rate

    good birth outcome is defined as live birth(s) at ≥37 weeks, with infant birth weight between 2500 and 4000g and without a major congenital anomaly.

    at delivery

Secondary Outcomes (10)

  • Biochemical pregnancy rate

    12-17 days after frozen embryo transfer

  • Clinical pregnancy rate

    28-35 days after frozen embryo transfer

  • Implantation rate

    28-35 days after frozen embryo transfer

  • Pregnancy loss rate

    From the date of confirmation of pregnancy until the date of pregnancy loss, up to 9 months

  • Live birth rate

    at delivery

  • +5 more secondary outcomes

Study Arms (2)

Delayed FET

EXPERIMENTAL

Participants will receive 16-week tirzepatide pretreatment prior to FET alongside lifestyle modification guidance, with a target weight loss of 10%-15% of total body weight.

Drug: Dual GIP/GLP-1 receptor agonist

Standard FET

NO INTERVENTION

Participants will receive lifestyle modification guidance and proceed to FET with no predefined weight-loss target.

Interventions

16 weeks treatment

Also known as: Tirzepatide
Delayed FET
