Abstract:
As a result of the COVID-19 pandemic, our centre made adjustments that reduced the number of patient visits, ultrasound scans, laboratory investigations, and face-to face instructions. The objective of this study was to evaluate whether these changes had any effect on the pregnancy rate for patients undergoing infertility treatment. The primary outcome was clinical pregnancy rates from intrauterine insemination and frozen embryo transfer. Clinical pregnancy rates were not statistically different between patients who underwent either procedure before and after the protocols were put in place. It is reassuring to know our pandemic protocol adjustments did not have a negative impact on infertility treatment outcomes.
