8 Known Causes of Low Sperm Count in Men

Low sperm count and male infertility have become so common in recent years, resulting in unhappy homes and unfulfilled hopes, obviously due to many of the often-ignored factors such as environmental toxins, lifestyle factors, and so on, all of which have massively influenced male fertility and their inability to get a woman pregnant.

According to the WHO, in order for a couple to produce a healthy pregnancy, the male partner’s sperm must meet the following criteria:

Normal sperm count > 20 million sperm cells/mL

— Sperm motility > 50%

— Morphology (size and shape) of about 30%

What is Low Sperm Count?

Low sperm count also known as oligospermia is when a man sperm in the semen is lower than 15 million per milliliter and when a man has low sperm count, he will find it hard getting a woman pregnant

Though men with this condition can still make a woman to conceive and have a baby but the chances of it happening always low

Low sperm count is one of the major cause of infertility in men worldwide and it occurs mostly in elderly people.

Male sperms abnormalities can ideally be categorized into the following headings:

Oligospermia (low sperm count): This accounts for about 10 -15% cases of male factor infertility.

– Asthenospermia (poor sperm motility): This is often associated with DNA fragmentation and increase the risk of transferring a genetic disease.

– Teratospermia (abnormal sperm morphology): This refers to the shape and structure of the sperm

The above mentioned sperm problems can seriously hinder a couple’s efforts to conceive, therefore early detection can save you a lot of time and help you choose the best treatment.

Unfortunately, many men, are unwilling to have a sperm health checkup (seminal fluid study) in order to identify an underlying infertility problem. This mindset is changing, though, as health education continues to spread over the internet.

As a result of our changing lifestyles, environmental destruction, and other factors, the problem of male infertility and low sperm count has become more common.

Here are the 8 Causes of Low Sperm Count in Men:

Abuse of drugs/substances:

Illicit substances like cocaine and marijuana can temporarily lower sperm count and quality, reducing a couple’s chances of conception by reducing the penile capacity to produce sufficient sperm. High drugs have also been linked to decreased sperm production.

Smoking  cigarette:

According to research, smoking reduces male sperm production and damages the DNA structure (genetic material) of sperm, lowering a couple’s chances of pregnancy by up to 20%. Smoking can also harm sperm quality and overall male fertility, making pregnancy more difficult.

Environmental Factors:

Environmental experts categorize pesticides, herbicides, insecticides, and other toxins and chemicals (e.g., pesticides, herbicides, and insecticides) as Endocrine Disrupting Chemicals (EDCs). According to research, the chemicals listed above lower sperm production in men by interfering with testosterone’s (male hormone) ability to generate new sperm.

Physical or Mental Stress:

Stress has been linked to a reduction in male sperm production as a result of hormonal imbalances caused by stress hormones (cortisol and adrenaline) in the body, which affect testosterone function indirectly.


Obesity can harm your fertility by causing hormonal imbalances in your body, reducing testosterone levels, and subsequently decreasing sperm production. When it comes to planning for conceiving, keeping your Weight between 20 and 24 kg/m2 is excellent.

Sexually Transmitted Diseases (STDs):

Bacterial infections such as Chlamydia Trachomatis and Gonorrhea are the most common causes of infertility in men, including sexually active women. This group of bacteria in men spread to the testis and epididymis (a tube that transports sperm from the testicles), obstructing sperm passage due to swelling caused by the infection.

Erectile Dysfunction:

In layman’s terms, erectile dysfunction or weak erection refers to the penis inability to keep and retain the level of erection required for satisfactory sexual performance. Many men suffer from this sexual health problem, which has been linked to low sperm production resulting in low testosterone levels in men.


Male infertility and decreased sperm production have been linked to age. When a man is older (70-80 years), it takes longer for him to get his spouse pregnant than when he is younger and sexually active.
