The condition called hypogonadism happens when there is little or no testosterone produced. The level of testosterone is important in men’s health. From sexual drive to building muscle mass and bone mass, testosterone levels are in play. Hence, knowing the signs and symptoms of low testosterone (or Low T) will help address the problem.

The signs of low T are often subtle. As such early detection is quite difficult. So paying close attention to your body will help reveal the true problem. Also known as andropause, this is the male version of menopause. Moreover, the decline in testosterone production may not be as evident as the decrease in estrogen in women. When this male hormone falls below 300 nanograms per deciliter, the person is diagnosed as having low T. When this happens, a variety of symptoms will emerge.

Decrease in sex drive

One of the most widely experienced symptoms is a decrease in libido. A decrease in this male hormone will undoubtedly decrease his sex drive. Moreover, low levels Low T can contribute to difficulty in achieving climax during intercourse.

Erectile dysfunction

Apart from the decrease in libido, low hormone levels can cause erectile dysfunction. Of course, testosterone alone is not responsible for an erection, but it play an integral role in stimulating the receptors to produce nitric oxide that triggers it.

Low sperm and semen volume

As an important part of semen and sperm production, lower testosterone levels can hamper production. In many low T cases, seminal fluid and sperm volume falls.

Decrease in muscle mass

Since this male hormone plays a vital role in building muscles, men with Low T experience a decrease in muscle mass. The areas that are usually affected include arms, legs and chest. Even with weight training, building up the muscle loss may be difficult.

Lower bone density

Osteoporosis or weakening of the bones also happens to men. Since testosterone helps in building and strengthening of bones, men with Low T can experience brittleness of the bones. The most susceptible areas include hips, feet, ribs and wrists.

Mood swings

If you think only women experience mood swing, you are very wrong. Men with Lot T also experience changes in moods. A decrease in testosterone in men can lead to depression, irritability and even lack of focus.

It is important that these signs and symptoms are identified early. This way, proper treatment of hypogonadism can be given. As the body changes; other aspects of one’s life change with it. By understanding what is happening in the body we become aware of how to address them properly.
