How Testosterone Levels Affect Male Fertility


Over the years there have been a number of misconceptions about male infertility, its underlying causes and its recommended treatments. Male infertility is a condition most commonly associated with a male’s inability to induce pregnancy in a female counterpart. This inability is often a direct result of low sperm count due to a testosterone deficiency.

How Does Low-T Affect Male Fertility?

Testosterone, a naturally occurring hormone produced within the testes, is derived from a series of chemical signals exchanged between the brain, specifically the hypothalamus and the pituitary gland. The production of gonadotropin-releasing hormone triggers the release of FSH (follicle-stimulating hormone) and LH (luteinizing hormone), both necessary to stimulate natural testosterone production. A direct connection exists between testosterone deficiency and a lack of healthy sperm production. Essentially, when testosterone levels are down, so is the sperm count, decreasing the probability of pregnancy induction. A number of internal and external factors are recognized causes of diminishing testosterone and infertility. These factors include, but are in no way limited to:


Nearly 30 percent of men experience testosterone deficiency between the ages of 40 and 79. The relation between age and testosterone deficiency need not be overstated as its association already carries a certain stigma. However, this group may attribute their deficiency to other health related issues associated with aging.


Failure to maintain good health may be stalling the body’s natural testosterone production. Many illnesses contribute to changes in the body’s normal hormonal balance. Conditions most commonly associated with male infertility are hypertension, diabetes, liver or kidney failure and thyroid disease. Obesity is also one of the many health risks associated with male infertility.


Less than healthy lifestyle choices take a toll on the way our bodies perform their natural functions. Consumptive habits like smoking, substance abuse, physical inactivity and an unhealthy diet ultimately damage the body and negatively impact natural testosterone production.

Medication Use

Certain prescription medications have been known to interfere with or completely halt T creation. It is never recommended that medication is stopped or altered without the approval of a physician. Set up an appointment with a fertility specialist to find out whether medications are to blame for diminishing fertility.


Stress is one of the biggest threats to male fertility. Stress creates the presence and continuous release of hormones that hinder the body’s ability to produce testosterone. It is important that stress levels are kept at a controlled minimum in order to maintain fertility.

Sleep Deprivation

Sleep deprivation robs the body of its ability to perform its routine self-maintenance, therefore hindering its ability to function at its best. So it should come as no surprise that denying oneself sufficient time to rest can have a negative impact on the body’s natural hormonal balance.

However, the great news is that infertility due to low testosterone is not usually permanent and often easily reversible. New medications and supplements promise to rapidly boost testosterone. But if the goal is to reestablish and maintain fertility, specialists recommend that you refrain from using these products as the spike in testosterone actually decreases healthy sperm production. There are several lifestyle changes that can be made in order to promote healthy, natural testosterone production and improve fertility.
