Libido, also called the sex drive, is defined as the level of sexual desire and sexual motivation a person has. 
Importantly, there’s no clinical metric or quantifiable way to measure male or female libido itself—every person has their own libido, and gauging its health is largely a matter of comparing your current libido to past libidinal patterns and evaluating whether changes in your libido are hindering your quality of life.
If you’re wondering how to increase male libido—or how to increase libido in general—the good news is a growing body of research points to several reasons, psychological and biological, why yours may be under pressure. Here, we’ll discuss possible root causes behind decreased libido and what you can do to help boost your sex drive and overall sexual health.
Libido, sexual responsiveness, and sexual behavior in general are governed by multiple systems of the body as well as extensive psychological and social factors.  Much of what controls a healthy libido isn’t yet well understood, but it’s thought libido is controlled by a complex of factors, including [1-2]:
Researchers believe the neural patterns that create male and female libido are largely the same. However, sexual response systems tend to function distinctly between biological sexes. 
A different ratio of hormones, different anatomy, and differences in male and female nervous systems are thought to be the major factors contributing to these sex differences.  For this reason, treating low male libido can require different interventions from those used to treat low female libido.
A lowered libido is defined as a noticeable decline in a person’s sexual interest or desire.
Healthcare providers class low libido within a larger clinical category of sexual dysfunction, which can also include the physical loss of sexual function—not the same as a loss of libido. When the libido has lowered enough to the extent that it’s considered clinically significant, a healthcare provider may refer to it as hypoactive sexual desire disorder (HSDD). HSDD can occur in both biological men and women. [3-4]
Many factors can lead to a lowered libido, and in many cases, a decline in sexual interest is non-pathological, even normal. For instance, people experiencing grief, major life transitions, or simply getting older may find they have a reduced desire to have sex or fantasize about it.
That said, a sudden decline or chronic absence of libido could point to an underlying health condition or hormonal imbalance. For instance, reduced libido could be tied to:

Sometimes, a reduced libido can point to an underlying health condition, such as:
Depression – Depression is a psychological disorder that affects both mood and a person’s physiology. A lack of interest in sex is a common symptom or side effect of depression.  Moreover, people who take SSRIs (selective serotonin reuptake inhibitors) may experience a lowered sex drive as a result of their medication. They can also experience ED or anorgasmia (difficulty reaching orgasm). 
Endocrine system disorders – In some cases, low libido may result from underlying health conditions impacting hormones. These could include thyroid diseases like hypothyroidism or disorders affecting your adrenal gland.
Addiction or drug abuse – Being a regular alcohol or drug user may have deleterious effects on libido, particularly in regard to testosterone production. For instance, having between 10 and 14 drinks per week has been shown to diminish testosterone production, elevate estrogen levels, and encourage your body to get rid of testosterone in your bloodstream faster.  By the same token, opioid use can interfere with the circuits in your brain responsible for making testosterone. In addition to impacting libido, this can also result in low T, lower sperm count, and lower-quality sperm. 
Living with a chronic health condition – Whether type 2 diabetes or high blood pressure, receiving a diagnosis for and living with a long-term health condition can be challenging for your mind and your body. It’s common to experience depression or anxiety—or simply feel disinterested in intimacy—if you’re preoccupied with trying to engage with life on life’s terms when you’re sick.
It’s important to understand that sex drive can be an important marker of an individual’s health. As such, committing to making long-term lifestyle changes could help restore your sex drive and promote your overall well-being.

Sexual shame—including shame about natural fluctuations in libido—can also make it harder to feel sexually inspired. You might consider communicating openly with your partner(s) about your feelings to help reduce any sense of stigma you may be feeling.
Ultimately, if you’re experiencing low or unpredictable libido levels and don’t know why, it’s important to consult a healthcare provider to help identify possible causes. They can conduct a thorough medical evaluation accounting for your health history and screen for conditions that could be contributing to decreased libido.
Finding the root causes of a lowered libido can take some work, but getting a sense of how your hormone levels stand can help bring some clarity to how to increase libido in men.
