Stress is known to take a toll on the body in countless ways — and a doctor has now explained what it may be doing to men’s sperm.
For many people, everyday life comes with constant pressure, from demanding jobs and family responsibilities to the ongoing strain of rising living costs.
And for those hoping to start a family, that ongoing stress could be another concern, after a doctor highlighted how stress may influence sperm health.
Stress doesn’t just affect mood — it can also trigger physical changes. When the body is under pressure, it releases hormones such as cortisol and adrenaline. While this response can be useful in short bursts, long-term stress is where problems can build, sometimes disrupting sleep and impacting libido.
“It takes about two to three months for sperm to be produced, mature and show up in the semen. That is one reason chronic stress may matter more than a short-lived stretch of stress,” Dr. Jamin Brahmbhatt wrote in CNN Health.
He added that the impact may go further than timing alone: “Chronic stress may also raise oxidative stress in the body, which can damage sperm directly.” He also points to research that supports these concerns.
According to the doctor, studies have found that higher stress levels can be associated with a lower sperm count, as well as reduced sperm movement.
So what can men do if they think stress may be playing a role? Dr. Brahmbhatt acknowledges that it’s not realistic to simply “switch off” stress, but says it can help to look at the behaviours stress can drive — like drinking more alcohol than usual, or getting less sleep. He also encourages regular physical activity, noting it doesn’t need to be intense to be beneficial.
For people feeling overwhelmed by the pressure of trying to conceive, he also suggests avoiding certain online spaces — particularly social feeds filled with baby announcements and gender reveals.
“If you are already struggling, that content is not inspiration — it’s fuel for anxiety and a fast track to feeling inadequate,” he writes.
In general, it’s often recommended that couples seek medical advice if they’ve been trying to conceive for six months when the female partner is under 35, or after a year if the female partner is older. People with known risk factors are commonly advised to speak to a professional sooner.
Of course, stress is only one potential factor. A wide range of issues can affect male fertility. In a separate discussion, Dr. Bobby Najari wrote for the New York Post that one of the most common causes of male infertility is varicocele — swollen veins in the scrotum.
Varicoceles may reduce sperm production and affect how well sperm move, which can in turn impact fertility. Possible signs can include testicles that appear different in size and a lump or mass in the scrotum.
For anyone worried about fertility, the advice remains the same: speak with a doctor to explore what may be happening and identify the most appropriate next steps.
