Testosterone is primarily a male hormone but is also present in females throughout their lifespan. Testosterone is a key hormone mainly produced in the testicles in men and is profoundly crucial in stimulating sperm production.
Besides this particular hormone also plays a significant role in the development and function of body organs such as brain, bones, heart and blood vessels.
Why and when do the testosterone levels decline?
Since it is such a pertinent male dominated hormone, it is imperative to know the reasons of its declination in some men. A vital question here to be answered is why do the testosterone levels in some men decline? What goes wrong?
It is empirically proven that after the age of 30, most men begin to experience a gradual downfall in their testosterone levels. Unfortunately, some believe that it is a normal part of aging. However, it isn’t so. A new study from Northwestern University shows that raising children actually causes a downfall in men’s testosterone levels. Some of the emerging evidences even suggest that men increasing rates of obesity and huge exposure to the environmental toxins also play a pivotal role in causing low testosterone levels in men. A study from University of California found that atrazine, a common pesticide, is so high in estrogen that it can literally transform a male frog into a fully reproducing female.
A change in lifestyle too plays a crucial part in falling of T levels. For instance, loss of a spouse, losing of a job, developing lifelong diseases such as diabetes do result into a fall in T levels in men.
Symptoms of Low Testosterone Levels
There are a range of symptoms that can occur if testosterone production drops dramatically.
1. Lower Sex Drive
It is quite normal to experience a lower sex drive in men after they cross the benchmark of 30; however, someone with low T is likely to experience a major drop in their desire to have sex.
2. Lower Semen Production
Quite undoubtedly, testosterone plays a significant role in the production of semen, a milky fluid that helps in the motility of the sperm. A man who has more testosterone will produce more semen, and the reverse is true too. Men with low testosterone will notice a conspicuous decrease in the production of their semen.
3. Erectile Dysfunction
Not only does a healthy level of testosterone help in maintaining a good sex life, it also aids in achieving an erection. Testosterone stimulates receptors in the brain to produce nitric oxide, a key molecule that helps in triggering an erection. Therefore, when testosterone levels are too low, a man will have difficulty in achieving an erection prior to having sex. Also, it is quite common to experience spontaneous and random erections at any time without any external stimulus.
4. Loss of Muscle Mass
Testosterone is partially responsible in building and strengthening of muscle. And, therefore, when a man sees a downfall in his testosterone levels, he is likely to notice a decrease in muscle mass and overall strength. It becomes very difficult for men to build or rebuild muscles during this time.
5. An Increase in Body Fat
Another symptom that may occur when the testosterone levels fall down is an increase in overall fat of the body. Sometimes, men may even develop “gynecomastia”, a condition in which they develop enlarged breasts.
6. Loss of Energy
It is quite common to see extreme fatigues and decrease in energy levels in men with low testosterone levels. If you feel tired all through the day even after taking proper sleep, or if you are finding it hard to exercise, low testosterone levels could be the reason.
7. Loss of Hair
Chest hair and overall body hair found on a man’s skin are due to high testosterone levels. Men who experience a fall of this particular hormone are likely to see a tremendous amount of hair loss over a time period.
8. Mood fluctuations
A fall in testosterone levels impacts emotional wellbeing of a man. Men with low T levels can experience mood and mental capacities. Some studies have shown that men with lower T levels are more vulnerable to depression and irritability.
