Gates-Funded Self-Assembling Microcrystal Implants Mark a New Phase in Population Control

Irreversible anti-fertility implants would accelerate the global population collapse already forecast by Gates-funded studies.

A new study published in Nature Chemical Engineering titled “Self-aggregating long-acting injectable microcrystals” reveals Bill Gates’s latest investment. As expected, this “innovation” does not improve the health of humanity by any means, but instead seeks to further reduce already-collapsing birth rates.

The technology, dubbed SLIM (Self-aggregating Long-acting Injectable Microcrystals), enables the self injection of microcrystals that self-assemble into a semi-permanent drug implant. The implant slowly releases synthetic hormones like levonorgestrel—a potent contraceptive—over months to years.

While the study frames SLIM as a step forward in medical innovation, closer inspection reveals grave concerns:

Irreversible implants: Once injected, the microcrystals self-assemble into a dense, solid mass deep in subcutaneous tissue. The study provides no method for removal, raising the possibility that these implants are effectively permanent, particularly in low-resource settings without surgical infrastructure.
Unknown long-term effects: In rats, the solid implant remained intact for at least 97 days—the full length of the study. In humans, where metabolism is slower and tissue clearance is more complex, these structures could persist for years with unknown consequences.

Widely available, extremely long-lasting anti-fertility implants are a dream come true for depopulationists. Bill Gates, the funder of this study, publicly revealed his preference for reducing the population by 10-15% in order to “get CO₂ to zero.”

“First we’ve got population. The world today has 6.8 billion people, that’s headed up to about 9 billion. Now, if we do a really great job on new vaccines, healthcare, reproductive health services, we could lower that by perhaps 10-15%” - Bill Gates at TED2010

The Gates Foundation also funded a study that was published last year titled “Global fertility in 204 countries and territories, 1950–2021, with forecasts to 2100: a comprehensive demographic analysis for the Global Burden of Disease Study 2021.” They estimated irreversible population collapse within the next few decades:

By 2050, over three-quarters (155 of 204) of countries will not have high enough fertility rates to sustain population size over time; this will increase to 97% of countries (198 of 204) by 2100.

Let’s get this straight: The same foundation that acknowledges an inevitable population collapse—without any intervention—is simultaneously funding invasive technologies that would only accelerate it:

We need to reverse the major decline in birth rates to preserve civilization. A few months ago, I identified some key targets:

A study by Aitken found that fertility rate declines are driven by both short- and long-term factors. In the short term, socioeconomic drivers like urbanization and delayed childbearing, as well as issues such as obesity, falling sperm counts, and environmental toxicants (e.g., pollutants, nanoplastics, and electromagnetic radiation), compromise reproductive health. Long-term factors include reduced selection pressure on high-fertility genes due to smaller family sizes and the widespread use of assisted reproductive technologies, which may perpetuate poor fertility genotypes in the population. Addressing these issues is essential to mitigating the ongoing fertility crisis.
