Brief Summary
Vitamin D is best known for keeping our bones healthy, but growing research suggests it may also play a role in fertility. Many In vitro fertilization (IVF) clinics now routinely check vitamin D levels and prescribe supplements before treatment, but the science is still unclear on whether this actually improves the chances of pregnancy. Our study, based in the United Arab Emirates (UAE), aims to find out whether a woman's vitamin D level on the day of her frozen embryo transfer (FET) makes a difference to whether she becomes pregnant and delivers a baby. The UAE is an ideal setting for this research, as vitamin D deficiency is particularly common in the region. The findings could shape how fertility clinics screen and treat women seeking fertility treatment in the future.
Eligibility Criteria
Inclusion: * Women undergoing frozen embryo transfer (FET) at Fakih IVF. * Age between 18 and 40 years. * Body mass index (BMI) between 18 and 40 kg/m². * Patients who had serum vitamin D levels assessed within three months prior to FET * Supplementation with Vitamin D if deficient \< 30 ng/mL (75 nmol/L). Exclusion: * Age below 18 years or above 40 years. * BMI below 18 kg/m² or above 40 kg/m². * Patients who did not have vitamin D levels measured within three months prior to FET. * Patients who were found to have low vitamin D levels but did not receive supplementation. * Patients with recurrent implantation failure (RIF). * Patients with known uterine factors affecting implantation (e.g., congenital uterine anomalies, intrauterine adhesions, submucosal fibroids). * Patients with significant medical comorbidities that may affect pregnancy outcomes.
