Objective: To review the current knowledge concerning COVID-19 vaccination and assisted reproductive techniques (ART). Methods: A systematic review in Pubmed-Medline, the Cochrane Database, the Web of Science, and the National Guideline was performed. Studies were selected if they were primary studies, included vaccinated (case) and unvaccinated (control) patients, and described fertility treatment response. Results: A total of 24 studies were selected. Outcomes related to the association between COVID-19 vaccination and ART were collected. The vast majority of studies found no statistical differences concerning oocyte stimulation response, embryo quality, implantation rates, or pregnancy outcome (clinical or biochemical pregnancy rates and losses) when comparing cases and controls. Similarly, no differences were found when comparing different types of vaccines or distinct ART (artificial insemination, in vitro fertilization, and embryo transfer of frozen embryos). Conclusions: Patients receiving ART and health care professionals should be encouraged to complete and recommend COVID-19 vaccination, as the available evidence regarding assisted reproductive outcomes is reassuring.

VACTERL association represents a rare condition with a broad spectrum of coexisting congenital abnormalities. Although a multifactorial origin has been described, the etiology is still unclear. Prenatal diagnosis can be challenging, as specific characteristics may be difficult to be determined before birth. This case report describes the finding of multiple congenital abnormalities in a male fetus at 30 weeks of gestation. The most notable findings were the presence of duodenal stenosis, esophageal atresia with distal tracheoesophageal fistula (type 3), interatrial septal communication foramen ovale, and left nostril and choana agenesis. After birth and making a broad differential diagnosis, all these characteristics oriented the diagnosis towards the VACTERL association. To the best of our knowledge, no cases of VACTERL association and unilateral nostril and choana agenesis have been previously described.
