For both men and women, their bodies produce estrogen and testosterone. These are the female and male hormones that are responsible for many common attributes that both men and women possess. With regard to testosterone, this is responsible for a deeper voice, more muscle mass, sexual drive, energy levels, stamina, and much more.
Testosterone production begins to decline during the latter portion of their 20s, into their 30s, and begins to bottom out in the 40s. Even testosterone levels that are increased through various testosterone boosting supplements may not be helping very much, depending on how that increase in testosterone is being held within the body.
For example, most of the testosterone that is produced through these supplements may be bound to either SHBG (Sex Hormone Binding Globulin) or the protein albumin. It may also be converted into estrogen.
Focusing on ingredients that not only help to boost testosterone levels, but that also prevent them from being bound to SHBG or albumin or converted into estrogen is the key to boosting ‘free’ testosterone levels.
Massularia acuminata is one of those ingredients found in numerous testosterone boosting supplements on the market today.
What is Massularia Acuminata?
Massularia acuminata is a shrub that is commonly grown and found throughout Western Africa and has been used for medicinal purposes for thousands of years. It is reported that this herb may be effective at promoting sexual health due to its ability to increase endogenous testosterone levels as well as luteinizing hormones.
Luteinizing hormones are responsible for boosting testosterone levels, but as noted earlier it is also necessary to ensure that this becomes ‘free’ testosterone. It is the luteinizing hormone that signals the body to create more testosterone in the testes. Both of these hormones (testosterone and luteinizing hormone) work together to promote positive sexual health in men and women. They are also responsible for promoting peak physical performance.
How Effective is Massularia Acuminata at Boosting Testosterone Levels?
In recent years there have been numerous research studies that were testing the effectiveness of Massularia acuminata on boosting testosterone levels. These research studies indicate that the phytochemical constituents contained in Massularia acuminata, i.e. the alkaloids, saponins, and polyphenolics may actually support the production of testosterone, but only in a dose-dependent manner.
In the highest dose provided to the test subjects, it produced an increase in testosterone production by about 60%, with a supplemental increase in luteinizing hormone of about 66%.
What this indicates is that higher dosages of Massularia acuminata may produce higher levels of testosterone production, so depending on the type of testosterone boosting supplement you are looking at, if the dosage is lower than what these research studies found, you may experience lower levels of testosterone production (according to some claims). In some products, you may not have any indication about how much Massularia acuminata is actually being used in that particular supplement.
Some men who have used various supplements that contain Massularia acuminata have reported an increase in strength gain, thicker and fuller muscles, improved sexual health, better recovery times after workouts, increased stamina, and improved self-esteem as a result of these factors.
These reported benefits need to be supplemented by professional research studies. We were only able to find three research studies, but all done on laboratory rats. We are hopeful that human male subjects will be tested in the near future to determine how effective Massularia acuminata is at actually increasing testosterone production in the body.
The research studies that we did find are included here.
In 2011, Yakuba and Akanji at the Phytomedicine, Toxicology, Reproductive and Developmental Biochemistry Research Laboratory, Department of Biochemistry, University of Ilorin in Nigeria conducted a test using 60 male rats to determine the effect of aqueous extract of Massularia acuminata on sexual behavior of male Wistar rats.
They divided these rats into four groups of 15. The rats in group A were the control group and were given 1 mL of distilled water. The rats in groups B, C, and D were given the same volume of water, but the distilled water contained 250, 500, and 1000 mg/kg body weight of the extract, respectively.
The researchers noted a significant increase in serum testosterone levels in those laboratory rats who had received 250 mg/kg body weight on days 1 and 3. This was an increase of 77% in overall testosterone levels.
There was no noted increase in testosterone production for the rats that received 500 and 1,000 mg/kg body weight as compared to the group B. However, there was an increase in the frequencies of mount and intromission among these rats in group C and D.
It may be the result of the alkaloids and saponins that led to the increase in sexual appetite for the laboratory rats in groups C and D. Overall, it is evident that Massularia acuminata can help to boost testosterone levels among adult male rats.

Conducted in 2011 by Yakuba, Awotunde, et al. at the Phytomedicine, Toxicology, Reproductive and Developmental Biochemistry Research Laboratory, Department of Biochemistry, University of Ilorin in Nigeria, these researchers tested the sexual effects of aqueous extracts of Massularia acuminata on male Wistar rats. It is unclear the sample size of these rats, but they received various dosages of aqueous extract of Massularia acuminata. The dosages ranged from 50, 100, and 200 mg/kg body weight.
With all of the dosages and test groups, the concentrations of serum testosterone increased. Also, serum luteinizing and follicle stimulating hormones all increased as well among the tested groups, compared to the control groups. There was also an increase in sexual behavior and appetite among the test laboratory rats, increasing with the increase in dosages.
As for the actual boost in testosterone levels, it appears to be relatively stable between the 50 mg, 100 mg, and 200 mg test groups. This means that there may not actually be an increase in testosterone production with an increase in the amount of Massularia acuminata provided.

In the final research study that we found regarding Massularia acuminata, it was conducted in 2008 by Yakuba, Adewumi, et al. at the Phytomedicine, Toxicology, Reproductive and Developmental Biochemistry Research Laboratory, Department of Biochemistry, University of Ilorin in Nigeria. These researchers studied the androgenic potential of aqueous extract of Massularia acuminata on male Wistar rats.
The laboratory rats received 250, 500, and 1000 mg/kg body weight of the plant extract.
The laboratory rats were divided into four groups. The first group was the control and received 1 mL of distilled water. Groups B, C, and D received 1 mL of distilled water, but containing 250, 500, and 1000 mg/kg body weight of the extract, respectively, for a period of 21 days. The rats were tested at 1 day, 7 day, and 21 day cycles.
The researchers noted a significant increase in testicular testosterone production. The increase was measured at approximately 50%. They also found a significant increase in luteinizing and follicle stimulating hormone concentrations.
The researchers noted that Massularia acuminata stem may have androgenic potential to stimulate male sexual maturation and enhance normal testicular function.

Even though the research studies that have been conducted regarding Massularia acuminata and its ability to boost testosterone levels were only done on laboratory rats, there is compelling evidence to support the fact that Massularia acuminata can actually boost testosterone levels.
There are numerous claims on the market that an increase in the amount of Massularia acuminata added to certain boosting supplements is going to increase the production of testosterone, but the research we have found does not support this claim. In other words, there is no difference between 250 mg/kg body weight supplements and 1000 mg/kg body weight.
As more research studies are conducted, especially on adult human males, we will review those and publish those findings here.
