Conditions
Summary
This is a randomized, controlled clinical trial with a two-sided superiority hypothesis. The study evaluates whether a 12-week pre-treatment with semaglutide prior to ovarian stimulation improves the number of good-quality blastocysts in overweight and obese women undergoing in vitro fertilization (IVF), compared to no pre-treatment.

Interventions
Participants in this group will receive semaglutide for 12 weeks before ovarian stimulation (0.25 mg/week in weeks 1-4, 0.5 mg/week in weeks 5-8, and 1 mg/week in weeks 9-12). After pre-treatment, controlled ovarian stimulation will be initiated with 225-300 IU/day of rFSH, GnRH antagonist (0.25 mg/day) starting when follicles reach ≥14 mm, and ovulation triggered with triptorelin 0.2 mg when 2-3 follicles reach ≥18 mm. Oocyte retrieval will occur 34-36 hours later, followed by IVF/ICSI. Embryos will be cultured to blastocyst stage and cryopreserved. Embryo transfer will occur after an 8-week washout from semaglutide.
Participants in this group will undergo standard ovarian stimulation without semaglutide pre-treatment. Stimulation will begin with 225-300 IU/day of rFSH, GnRH antagonist (0.25 mg/day) starting when follicles reach ≥14 mm, and ovulation triggered with triptorelin 0.2 mg when 2-3 follicles reach ≥18 mm. Oocyte retrieval will be performed 34-36 hours later, followed by IVF/ICSI. Embryos will be cultured to the blastocyst stage and cryopreserved. Embryo transfer will follow standard clinical practice.
