As men age, they usually begin to experience changes in their body. The first significant changes happen during adolescence in the form of puberty. However, as adults, the body begins to produce less testosterone once we reach 24 or 25 years of age. It may level out for a while, but over a period of several decades the levels of testosterone in the body will continue to gradually decline.
What Impact Does Lower Testosterone Levels Have?
The most significant issues that will arise with regard to decreased testosterone levels in the body have to do with a loss of muscle mass, more difficulty adding muscle, reduced stamina, a lower libido, and decreased energy levels.
Most men will experience these issues during their late 20s, 30s, and most significantly in their 40s. Finding ways to naturally elevate testosterone levels in the body is a driving force for millions of men around the world.
Testosterone boosting supplements are abundant, and so are the ingredients used in many of them. Fadogia agrestis is one of them, but can it actually boost testosterone levels in the body?
What is Fadogia Agrestis?
Fadogia agrestis is an herb that is commonly found throughout Africa and has been used by numerous indigenous peoples for centuries as a fertility aid. Some outside scientists, when working with these indigenous tribes, found that it seemed as though Fadogia agrestis worked at boosting libido as well is fertility. That doesn’t mean it is actually effective at boosting testosterone levels.
We managed to find two professional research studies that were conducted on Fadogia agrestis to measure its effectiveness at boosting testosterone levels, however both of these involved laboratory rats rather than human subjects.
In order to provide a fair assessment about the potential and viability of Fadogia agrestis as a testosterone boosting herb, it’s important to find more research conducted on human test subjects.
How Effective is Fadogia Agrestis?
Let’s take a look at these two research studies that were conducted on Fadogia agrestis to determine the impact that it would have on male laboratory rats.
In 2008, Yakuba, Akanji, and Oladiji at the Medicinal Plants Research Laboratory, Department of Biochemistry, University of Ilorin, Nigeria wanted to determine the effects of oral administration of an aqueous extract of Fadogia agrestis on certain testicular function indices of male rats.
This research study took place over 28 days and included four different groups of laboratory, male rats. Group A was the control group that received a placebo. The other groups, labeled B, C, and D received graded dosages orally of 18, 50, and 100 mg/kg body weight of the plant extract.
What the researchers found in this study was that there may be adverse effects on testicular functions within the male rats that received this ingredient. What is most interesting to note with regard to this study is that higher dosages actually caused more problems for the function of the testes in these laboratory rats than lower dosages.
It is also important to note that these researchers did not find any viable evidence that it provided a testosterone boosting side effect.

The second research study we found that specifically focused on Fadogia agrestis was conducted in 2005 by Yakuba, Akanji, and Oladiji at the Medicinal Plants Research Laboratory, Department of Biochemistry, University of Ilorin, Nigeria. These researchers did an in vivo study on male albino rats and wanted to determine whether there were any aphrodisiac potentials for the aqueous extract of Fadogia agrestis.
The laboratory rats were divided into four groups. The first group, like the previous study, was the control group. The other groups received 18, 50, and 100 mg/kg body weight of the extract at 24 hour intervals. The sexual behavior parameters and serum testosterone concentration levels of each test rat were measured and evaluated at days 1, 3, and 5.
The researchers found that these various dosages produced two, three, and six fold increases compared with the control group at the end of the experimental period.
They also noticed an increase in sexual vigor of the three test groups. There may have been an issue with this particular research study, though. There apparently were saponins present in the aqueous extract of this plant that could account for an increase in testosterone levels. Saponins are known to raise the level of luteinizing hormones in the body. However, these researchers did not measure LH levels.

As with any particular research study that is conducted on only laboratory rats or mice, there is a significant gap in determining whether the particular ingredient is actually effective at boosting testosterone levels or not.
Complicating the situation even more for Fadogia agrestis is the fact that the only two research studies we could find on it found polar opposite results. The first study found no increase in testosterone levels and actual damage to the testicular function of the test rats. However, the second study showed some significant increases in testosterone levels in the body.
With the aforementioned issue with the second study and the potential for saponins to have been included in the extract, we will have to continue looking for more significant research on Fadogia agrestis to determine whether it is truly effective at boosting testosterone levels in the body. Check back for more updates as research is conducted on human test subjects, hopefully, in the future.
