In laboratories across Brazil, a quiet revolution is taking place that is reshaping the very building blocks of life. Petri dishes have become the unexpected starting point for both human families and the country's booming agricultural industry. Over the past decade, in vitro fertilization (IVF) has evolved from a medical curiosity to a powerful technology driving changes from fertility clinics to cattle ranches. Brazil now stands at a fascinating crossroads, leveraging identical reproductive technologies to address human infertility while simultaneously dominating the global embryo market for animal production.
ART births in Brazil in recent years
Largest embryo producer worldwide
This dual application of reproductive science showcases Brazilian innovation in both healthcare and agriculture. In the human realm, the country leads Latin America in assisted reproduction, while in agriculture, it has become the second-largest embryo producer worldwide, trailing only the United States 3 . The story of IVF in Brazil is one of scientific achievement, economic opportunity, and technological convergence, offering a unique case study in how a single technology can transform multiple sectors of society simultaneously.
Brazil's prominence in the Latin American fertility landscape is remarkable. The country has emerged as the undisputed leader in assisted reproduction within the region, recording approximately 83,000 births from ART treatments in recent years—more than double the number in Argentina (39,366) and nearly triple that of Mexico (31,903) 1 . This growth reflects both the expanding acceptance of reproductive technologies and the pressing need for them, as infertility affects an estimated 17.5% of adults globally, a statistic that holds true across income levels and regions 5 .
The Brazilian human IVF market has experienced significant financial growth, generating $154.6 million in revenue in 2023 with projections to reach $226.3 million by 2030, representing a compound annual growth rate of 5.6% 6 . This expansion is fueled by several factors: delayed pregnancies, rising infertility rates, and increasing awareness about available treatments. Among the various procedures, frozen nondonor embryos dominate the market, accounting for 48.25% of revenue in 2023 6 .
The structure of Brazil's fertility industry reveals much about how reproductive technologies have taken root in the country. Research shows that the majority of clinics (90.1%) operate in the private sector, making access largely dependent on personal financial resources rather than public healthcare coverage . These establishments tend to be small-scale operations, with 63.8% having up to 20 employees, and many have substantial experience—32% have been operating for more than 20 years .
Geographic distribution, however, tells a story of inequality. Services are concentrated in more affluent regions, particularly the southeast, which hosts 65% of the country's cryopreserved embryos . This distribution highlights the ongoing challenge of ensuring equitable access to fertility treatments across Brazil's diverse socioeconomic landscape.

While human IVF captures personal stories of hope, the application of similar technologies to animal reproduction has become an economic powerhouse for Brazil. The numbers are staggering: in 2022 alone, Brazil produced more than 538,000 bovine embryos, with approximately 340,000 destined for beef cattle and over 161,000 for dairy cattle 3 . This massive scale has positioned Brazil as the second-largest embryo market globally, trailing only the United States in production volume 3 .
The parallels between human and animal IVF in Brazil extend beyond basic techniques to encompass a shared ecosystem of innovation. Brazilian companies like InvitroSul, operating since 2007 in Rio Grande do Sul, exemplify how expertise in reproductive biotechnology serves both sectors. The company specializes in the genetic multiplication of high-value cattle through in vitro embryo production, working with European breeds such as Dutch, Angus, and Hereford 7 .
Their work, led by Dr. Carlos Eduardo Gomez Martin, "a specialist and pioneer in bovine reproduction biotechnology," demonstrates how knowledge transfers between human and animal applications 7 . Strategic partnerships with global leaders like Boviteq and Semex provide access to international expertise while adapting technologies to local breeds and conditions, particularly composite breeds like Braford and Brangus that are well-suited to Brazilian livestock farming 7 .
| Category | Number of Embryos | Primary Applications |
|---|---|---|
| Beef Cattle | 340,000 | Improving feed efficiency, weight gain, carcass quality |
| Dairy Cattle | 161,000 | Enhancing productivity, milk quality, herd health |
| Total Production | 538,000 | Genetic dissemination and herd improvement |

A pivotal 2020 study published in the journal "Assisted Reproductive Technologies in Brazil" provided unprecedented insights into the characteristics and operations of Brazilian fertility clinics . Researchers employed a mixed-methods approach, combining quantitative and qualitative methodologies to paint a comprehensive picture of the sector.
The quantitative component involved an online survey administered to fertility clinics across Brazil between 2016-2018, focusing on their operations during 2015-2016. Using the REDCap Program, a web-based application for survey construction and database management, researchers gathered data on service characteristics, treatments performed, patient profiles, and funding mechanisms . The study achieved a representative response rate, with 63.1% of responses coming from the southeast region, 23.8% from the south, 7.1% from the northeast, and 6.0% from the mid-west, closely mirroring the actual distribution of clinics nationwide .
The research revealed a sector marked by both maturity and concentration. A significant 32% of responding clinics had been in operation for more than 20 years, indicating an established and experienced industry . The distribution of clinic ages also showed interesting patterns, with the southeast region containing the highest number of long-established services (20 clinics operating for more than 20 years), while the northeast had no clinics of similar longevity among respondents .
Perhaps the most telling finding concerned the international appeal of Brazil's fertility services. An impressive 85.1% of clinics reported having treated non-Brazilian residents, highlighting the country's role as a regional hub for fertility tourism . This cross-border demand underscores both the quality of services and potential cost advantages compared to other markets.
| Characteristic | Distribution | Notes |
