Abstract
BACKGROUND: Pregnant mothers frequently have vitamin D deficiency, which has potential consequences for the health of their unborn children. Prenatal vitamin D administration raises maternal and foetal 25(OH)D levels. This study aims to assess the effects of 25(OH)D supplementation on clinical pregnancy and miscarriage rates in women diagnosed with hyperandrogenic polycystic ovarian syndrome (PCOS). MATERIALS AND METHODS: This prospective study was conducted on 200 patients with hyperandrogenic PCOS who attended an outpatient infertility clinic at Menoufia University Hospital from March 2021 until March 2022. Participants were divided into two groups-(A) women who received a therapeutic dose of 25(OH)D supplements (n=100) and (B) women who did not receive 25(OH)D supplements (n=100). RESULTS: The duration needed to reach follicles that were ≥18 mm was significantly higher in group B (16.74 ± 2.57) compared with group A (13.40 ± 2.12). Midluteal progesterone was significantly higher in group A (19.63 ± 2.12) compared with group B (17.74 ± 2.36, P<0.001). Our results indicate that women with adequate 25(OH)D levels are far more likely to experience clinical pregnancies than those with 25(OH)D deficiency. CONCLUSION: More research is necessary to determine whether vitamin D supplementation can be a simple and economical solution to increase pregnancy rates. Our study population had a significant 25(OH)D deficit or insufficiency prevalence. Determining 25(OH)D levels as part of a routine infertility assessment may be advantageous.
