When you get older, you will experience changes in your body, just like you did as an adolescent. However, for adolescents, the body begins to produce increased levels of testosterone which contribute to a deeper voice, more body hair, increased strength, and ultimately sexual drive in teenagers and young adults.
Once an adult male reaches the age of 24 or 25, they will begin to see the difference in these factors. You may have noticed it becoming more difficult to get through a workout, build more muscle, or even maintain the muscle you had already built up. You might also experience lower sex drive, more fatigue, less energy, and other changes.
For the most part, these changes are subtle, occurring gradually throughout the second part of your 20s, throughout your 30s, and into your 40s. By the time the adult male is in his 40s, he will most likely be experiencing all of these symptoms or side effects of diminished testosterone levels.
As a result, turning to testosterone boosting supplements is one way to help increase the levels of testosterone in the body naturally. The important factor to focus on, though, is not just boosting testosterone, but encouraging the increased levels of ‘free’ testosterone in the body.
Even though there may be an increase in testosterone levels throughout the body, it is most likely being bound to the Sex Hormone Binding Globulin, or a protein called albumin. It may also be converted into estrogen, which is the female hormone, but men also have certain levels of estrogen naturally occurring within the body.
Hibiscus macranthus is one of the many ingredients used in a variety of testosterone boosting supplements, and determining its effectiveness can help you figure out which supplements may be most useful to you.
Explaining Hibiscus Macranthus
Hibiscus macranthus is native to West-Central Africa, more particularly Cameroon, and is just one of many hundreds of plants that are found within the Hibiscus genus. The largest genus of the Hibiscus family contains about 300 different species.
In many cultures throughout West Africa, Hibiscus macranthus has been used to help boost male fertility. It has also been used to help regularize the menstrual cycle for women as well as addressing infertility in female subjects.
It has taken many years, but Hibiscus macranthus finally reached the testosterone boosting community. A research paper was published in the Asian Journal of Andrology and this study noted that Hibiscus macranthus was effective at increasing the production of testosterone in the body, and that researchers isolated methylene chloride as the important chemical in this reaction.
There have been other studies throughout the years that have focused on increasing body weight, strength, and even energy levels, but many of these research studies were conducted on laboratory rats rather than human male subjects.
How Effective is Hibiscus Macranthus?
Unfortunately, the use of ingredient in testosterone boosting supplements is still relatively recent and there is not a significant amount of research conducted on adult males. Some of the supplements on the market that promote an increase in testosterone focus more on decreasing estrogen levels as well as dihydrotestosterone. DHT (dihydrotestosterone) is the most potent form of testosterone, but only accounts for approximately 5% of the body’s total testosterone levels.
We found only two research studies conducted that directly tested testosterone levels with regard to Hibiscus macranthus. Both of these were conducted on laboratory rats, rather than human male subjects.
We have included these research studies here to take a closer look at the potential benefits that Hibiscus macranthus offers with regard to testosterone levels and production in the body.
Conducted in 2005 by Moundipa, Beboyl, et al. at the Department of Biochemistry, University of Yaounde in Cameroon, these researchers were looking to determine the effect of Hibiscus macranthus as well as Basella alba on testosterone production of adult rat and bull Leydig cells.
It was not noted the sample size of the test subjects, but they received methanol extracts of both ingredients.
The researchers concluded that at 10 g/mL of the extract, there was a slight increase in testosterone levels, but that testosterone production decreased significantly when the control group received 100 g/mL of the extract.
The researchers concluded in this study that Hibiscus macranthus extracts did not possess androgenic potential.

In 1999, Moundipa, Kamtchouing, et al. at the Department of Biochemistry, University of Yaounde in Cameroon tested laboratory Wistar rats on the effects of certain Hibiscus macranthus extracts for testis function.
These researchers found that serum levels of testosterone significantly increased after the 15th day of treatment. The increase was measured at 80% for rats that were given both types of extracts compared to the control group. The researchers also found that the treated rats showed high testosterone production in vitro (136 and 62%, respectively for treated and control rat after 15 days, compared to those of three days).
It was concluded that the Aquarius extract of Hibiscus macranthus and Basella alba had anabolizing and virilizing effects on these laboratory rats.

It is interesting to note that through both of these research studies, the researchers used a combination of Hibiscus macranthus and Basella alba. It is unclear why both of these extracts were used together or what impact Basella alba would have on boosting testosterone levels in the body.
There needs to be more research conducted on human male subjects and the effectiveness of Hibiscus macranthus at elevating testosterone levels in the body. We will keep looking for new research studies that will indicate just how effective Hibiscus macranthus can be at elevating testosterone levels for human male individuals. These research studies, summarized, will be posted here as they are published.
