Testosterone plays a vital role in puberty, which is the period when a young individual attains sexual maturity and becomes capable of reproduction.
In this article, we will discuss the role of hormones, specifically testosterone, in males’ sexual health. Let’s get started!
What is Testosterone?
The testicles and ovaries are responsible for producing testosterone, a hormone present in humans and various other animals. The quantity of testosterone produced, whether too little or too much, can have a substantial impact on both your physical and mental well-being.
In men, testosterone is primarily synthesized in the testicles, while women’s ovaries also generate smaller amounts of this hormone. The production of testosterone increases significantly during puberty and gradually declines after reaching around age 30.
Testosterone plays a crucial role in several aspects of human physiology. It is commonly associated with sexual desire and is vital for sperm production. Additionally, it influences bone and muscle mass, the distribution of body fat in men, and even the production of red blood cells.
It’s noteworthy that a man’s testosterone levels can also exert an influence on his mood.
The Role of the Hormones in Male
In the course of male puberty, several bodily changes usually take place:
- The penis and testicles experience growth.
- Facial, pubic, and body hair start to develop.
- The voice undergoes a deepening process.
- Muscles and bones become more robust.
- Height experiences growth.
Following puberty, testosterone continues to play a role in regulating:
- The production of red blood cells.
- Maintaining bone density.
- Distributing body fat.
- Enhancing muscle strength and mass.
- Promoting the growth of facial and body hair.
- Sperm production.
- Influencing sex drive.
How Does Testosterone Affect Sexual Desire?
The pituitary gland releases hormones into the bloodstream, signaling the testicles to produce both sperm and testosterone. These hormones then circulate back to the brain, heightening one’s libido. According to an expert, testosterone plays a crucial role in enhancing desire, making things appear, smell, taste, feel, and sound more sexually appealing. Additionally, it maintains the flexibility and health of penile tissues, facilitating better erections. Low levels of testosterone, on the other hand, can dull one’s libido.
What Causes Low Testosterone Levels?
As men age, it’s normal for their testosterone levels to decrease gradually. This decline may begin as early as their thirties, and research suggests that a yearly reduction of about 1 percent begins around the age of 45.
Additionally, lifestyle factors can influence testosterone production. Overexercising or having an unhealthy diet can have an impact. Furthermore, obesity is closely associated with lower testosterone levels.
If you have concerns about your testosterone levels, consulting your doctor is advisable. They can arrange for a blood test to determine if your testosterone levels fall within the normal range.
What Does it Mean to Have Low Testosterone in Males?
In certain instances, low testosterone, often referred to as low T, can be attributed to a medical condition called hypogonadism. This condition arises when the body is unable to produce the usual levels of the hormone due to issues with either the testicles or the pituitary gland. In boys, hypogonadism is linked to a delayed onset of puberty, while in adult men, it can result in fertility problems and a diminished desire for sexual activity.
Specific Signs and Symptoms of Low Testosterone
The symptoms of low testosterone (commonly known as low T) can differ based on the cause and the age at which they manifest. In younger males, signs may encompass:
- Underdeveloped genitalia.
- Delayed puberty.
- Absence of secondary sexual characteristics, such as a deeper voice and facial hair.
For middle-aged or older men, symptoms can include:
- Decreased energy levels.
- Feelings of depression.
- Sleep disturbances.
- Reduced sex drive.
- Difficulty achieving or maintaining an erection.
- Decreased sperm count.
- Swollen or tender breasts.
- Decline in muscle and bone strength.
- Fertility issues.
It’s important to note that not all men with age-related low testosterone experience symptoms or are significantly affected by them. The severity of these issues can vary widely. Furthermore, symptoms like fatigue, sleep problems, and depression can also result from other factors such as medication side effects, mental health concerns, and excessive alcohol consumption.
Low Testosterone Prevalence: How Common is Low T?
According to a study, it was found that 1 out of every 4 men between the ages of 30 and 79 had total testosterone levels below 300 nanograms per deciliter (ng/dl), which is generally considered the lower limit of the normal range. Interestingly, there were no discernible differences in these levels among men of various races or ethnic backgrounds. However, it’s noteworthy that not all of these men were experiencing the effects of low testosterone. Out of those tested, 12 percent reported a decrease in their libido and 16 percent experienced erectile dysfunction.
Nevertheless, the study’s authors observed that the prevalence of symptomatic androgen deficiency, which refers to low T levels leading to noticeable health issues, is increasing.
Health Concerns Related to Low Testosterone
Testosterone deficiency in men has significant effects beyond just one’s sexual health. Low T is linked to several critical health issues, including:
- Musculoskeletal problems, such as osteopenia (reduced bone density) and sarcopenia (muscle mass loss).
- Obesity.
- Abnormal cholesterol levels.
- Type 2 Diabetes.
- Cardiovascular disease.
Testing Testosterone
A straightforward blood test can determine the levels of testosterone in your body. The range of normal or healthy testosterone levels in the bloodstream is quite broad. For adult males, normal testosterone levels typically fall within the range of 280 to 1,100 nanograms per deciliter (ng/dL), while for adult females, it’s typically between 15 and 70 ng/dL. It’s important to note that the specific ranges may vary among different laboratories, so discussing your results with your doctor is advisable.
If an adult male’s testosterone levels measure below 300 ng/dL, a doctor may conduct further investigations to determine the underlying cause of low testosterone. Low testosterone levels could indicate issues with the pituitary gland, which sends signals to the testicles to produce more testosterone. In the case of a low testosterone test result in a young teenager, it could be related to delayed puberty.
Moderately elevated testosterone levels in men may not produce many noticeable symptoms. In contrast, boys with higher testosterone levels may enter puberty earlier, while women with high testosterone levels may develop more masculine features. Excessively high testosterone levels could be associated with disorders of the adrenal glands or even testicular cancer.
There are also less serious conditions that can lead to high testosterone levels. For instance, congenital adrenal hyperplasia, a rare but natural condition that can affect both males and females, can lead to elevated testosterone production. If your testosterone levels are exceptionally high, your doctor may recommend additional tests to determine the underlying cause.
Testosterone Replacement Therapy
Hypogonadism, which is the reduced production of testosterone, may not always necessitate treatment. However, if low testosterone is significantly affecting your well-being and quality of life, you might be a candidate for testosterone replacement therapy. This therapy involves the administration of synthetic testosterone, which can be done orally, through injections, or using gels or skin patches.
Testosterone replacement therapy can yield positive outcomes, such as increased muscle mass and a heightened sex drive. It’s important to be aware that this treatment may also bring about certain side effects, including:
- Oily skin.
- Fluid retention.
- Reduction in testicle size.
- Decreased sperm production.
Some research studies have not shown a greater risk of prostate cancer associated with testosterone replacement therapy, but this remains a subject of ongoing investigation.
Furthermore, there is a study suggesting a reduced risk of aggressive prostate cancers among individuals receiving testosterone replacement therapy, although additional research is needed to confirm these findings.
Conclusion
Testosterone is most often linked to the sex drive in men, but it also plays a significant role in mental well-being, bone and muscle strength, fat distribution, and the production of red blood cells.
Both abnormally low and high levels of testosterone can have an impact on a man’s mental and physical health. A straightforward blood test conducted by your doctor can assess your testosterone levels. If your levels are found to be low, there is testosterone therapy available to address this issue.
If you suspect you have low testosterone, it’s a good idea to discuss the possibility of this therapy with your doctor to see if it could be beneficial for you.
