There are many websites today spreading alarm that the powers that be are trying to use Stevia as a surreptitious birth control and depopulation program. I took me all of 30 minutes to find the truth of the matter. Stevia is not a contraceptive. Not for humans. Perhaps for rats, at incredible dosages, but Stevia has only negligible effects.
Here is a reader friendly page about Stevia. Please note: Stevia, being a natural plant (weed) cannot be patented. One can grow it and boil the leaves.
Now, while it is true there were publications by elitists who sought to use Stevia as a possible tool in the depopulation mission, those publications referred to only ONE study that has not been replicated. That one study was done in 1968. Since many of us have become aware of the dangers of artificial or alternative sweeteners, we should be doing better research and finding the truth in these very important matters.
- Aspartame was invented in 1965.
- The ‘contraceptive stevia’ study was done in 1968
- The book “Population, Resources, Environment: Issues In Human Ecology” was published in 1970
So I submit to you, dear reader, the following:
Aspartame NutraSweet beginnings
Aspartame was invented by chemists at G. D. Searle & Company in 1965. Searle was bought by Monsanto in 1985. In March 2000, Monsanto, which was then a subsidiary of the Pharmacia corporation, sold NutraSweet to the private equity firm J.W. Childs.
There is an outstanding article showing the life of Aspartame:

3 years later, a ‘study’ was done on a natural sweetener called Stevia. Here it is.

Contraceptive Properties of Stevia rebaudiana.
A water decoction of the plant Stevia rebaudiana Bertoni reduces fertility in adult female rats of proven fertility. The decoction continues to descrease fertility for at least 50 to 60 days after intake is stopped. The decoction did not affect appetite and apparently did not affect the health of adults rats.

Note: This experiment has failed replication and again, it was done on rats. It is also interesting to note that one of the authors of the study had only two of his researches published.

Effects of chronic administration of Stevia rebaudiana on fertility in rats.
A study conducted on prepubertal male rats showed that chronic administration (60 days) of a Stevia rebaudiana aqueous extract produced a decrease in final weight of testis, seminal vesicle and cauda epididymidis. In addition, the fructose content of the accessory sex glands and the epididymal sperm concentration are decreased. Stevia treatment tended to decrease the plasma testosterone level, probably by a putative affinity of glycosides of extract for a certain androgen receptor, and no alteration occurred in luteinizing hormone level. These data are consistent with the possibility that Stevia extracts may decrease the fertility of male rats.

We still have yet to see any effects on humans! Just on rats and the effects are negligible with regular doses. What is showing results is a mass one time dosage that will require an obscene amount of Stevia intake.

Safety evaluation of aqueous extracts from Aegle marmelos and Stevia rebaudiana on reproduction of female rats.
The purpose of this study was to evaluate the safety of a Thai medicinal plant, Aegle marmelos, and a non-caloric sweetener, Stevia rebaudiana, on the reproduction of female rats. Female rats were treated orally with aqueous extract of A. marmelos (6%) and S. rebaudiana at various concentrations (0, 0.2, 1, or 10%) for 60 days (1 ml/day) before mating. The control rats received only distilled water. At the end of the treatment period, treated females were mated with untreated males and the effects on reproduction were examined at day 14 of pregnancy. No notable abnormalities were observed in any of the pregnant rats. The number of corpus lutea, implanted and dead fetuses, as well as the sizes of the fetuses in the treated rats were not significantly different from those of the controls. Based on these results, it may be concluded that aqueous extracts of A. marmelos and S. rebaudiana at the concentrations used in this study do not alter the reproduction of female rats.

Although this is not about sterility it warrants noting for the chromosomes.

Mutagenicity and human chromosomal effect of stevioside, a sweetener from Stevia rebaudiana Bertoni.
Leaves of Stevia rebaudiana Bertoni have been popularly used as a sweetener in foods and beverages for diabetics and obese people due to their potent sweetener stevioside. In this report, stevioside and steviol were tested for mutagenicity in Salmonella typhimurium strains TA98 and TA100 and for chromosomal effects on cultured human lymphocytes. Stevioside was not mutagenic at concentrations up to 25 mg/plate, but showed direct mutagenicity to only TA98 at 50 mg/plate. However, steviol did not exhibit mutagenicity in either TA98 or TA100, with or without metabolic activation. No significant chromosomal effect of stevioside and steviol was observed in cultured blood lymphocytes from healthy donors (n = 5). This study indicates that stevioside and steviol are neither mutagenic nor clastogenic in vitro at the limited doses; however, in vivo genotoxic tests and long-term effects of stevioside and steviol are yet to be investigated.

So, how about we connect some dots. The book exclaiming the contraceptive value of Stevia:
Population, Resources, Environment: Issues In Human Ecology Hardcover – 1970
by and Anne Ehrlich Ehrlich Paul (Author)
..refers to the supposed legend in Paraguay which has yet to be proven.
A comprehensive list of studies can be found here: (hint: there is no contraceptive effect)

There is no legend about Stevia and contraception
Effects on Reproduction.
An interesting pseudo-phenomenon arose at one time, and, sadly, still receives attention from time to time, in the popular press and even by serious scientists. It is sad because the whole thing is a hoax; if not that, it is at least a case of very badly mistaken identity. It seems that in 1968 a paper appeared that claimed that certain tribes of Indians in Paraguay (the Matto Grosso) used stevia tea as a contraceptive, with apparently very good results27 In subsequent experimental work, utilizing rats, these researchers found that the treatment was supposedly good for periods up to 2 months.
Subsequent work has repeatedly failed to replicate the 1968 study.28-31 Furthermore, at least one attempt to locate tribes in northeastern Paraguay that used stevia to control fertility failed to confirm the story. One effect on reproductive physiology that appears to be valid, but which is in need of further study before definitive conclusions can be drawn, is a healing effect on the processes underlying prostate disease.32 Just how important this finding is must await further research.
Although I have done the research, and provided copious links, do not believe me! Do your own research! Really. We have to be responsible for our freedoms. While we have the tools, such as the internet, we must use them responsibly.
If the elitists want to cite bad and unproven ‘research’, to attain their ill-gotten goals, let them pursue their folly.
