Title

Comparative analysis of the Incidence of frozen embryos in the last three years by country region and the northeast region

Objective

To determine the incidence of frozen embryos in the last three years by region of the country and to analyse such incidence on the northeast region.

Methods

Descriptive, cross-sectional and quantitative study using secondary data obtained by the National Embryon Production System. The target population were women that donated embryos in all regions of Brazil, regardless of the maternal age group, in the period from Jan/2020 to December 2022. The data obtained were reorganized and analyzed using simple descriptive statistics.

Results

During the year 2020 the total frozen embryos were 85,448. In the northern region there were 1,235, northeast 8,642, central-west 5,709, southeast 59,777 and south 10.085. In 2021, the total number were 108,469, with the following values for each region: North 1.084, Northeast 12.543, Central-West 8.009, South-East 73,947 and South 12.916. In the year 2022, the total number were 103,931 with the number of embryos in the North region 1,106, the Northeast 10,467, the Midwest 7,940, the Southeast 71,966 and the South 12,452. In 2021, there was a 45.41% increase in the number of frozen embryos in the northeastern region compared to the previous year. Nonetheless in 2022, there was a drop of 16.55% compared to the previous year. The states that concentrated the most actions were Bahia, Pernambuco and Ceará.

Conclusion

In recent decades, there has been a 255% increase in the number of frozen embryos in Brazil (SisEmbrio, 2022). This increase is largely due to the growth of assisted reproduction with improved techniques and the feasibility of access (SBRA, 2022). Our survey is corroborated by the fact that in 2021 there was a 45% increase in the number of frozen embryos in the northeastern region compared to the previous year. Meanwhile, it points to a 16% drop in 2022, compared to the previous year. Despite this regression, the rate of frozen embryos in 2022 in the northeastern region was 21% higher than 2020. As the study covers the years of the COVID-19 pandemic, which may justify lower rates. Nevertheless, the Northeast accounts for 10.62% of the national frozen embryos scenario and it is worth noting its advance in this scenario.
