Male infertility is not much discussed but it is an important aspect of achieving parenthood.
Male infertility is a prevalent issue affecting nearly 1 in 7 couples who struggle to conceive a child despite engaging in frequent, unprotected sexual intercourse for a year or longer. In approximately half of these cases, male infertility contributes to difficulties in conception.
This article explores the various causes, symptoms, and available treatments for male infertility, providing valuable insights for individuals seeking to understand and address this challenging condition.
Having a child is bliss. But there are many childless couples around the world, who have faced difficulty in having a child.
One out of eight couples around the world is infertile due to numerous reasons. Infertility can be attributed to both male infertility and female-related infertility and here we will elaborate on the causes of male infertility and how to manage it.
The main symptom of male infertility is the fact that the couple is unable to conceive a child even after a year of unprotected regular intercourse. There may be no other symptoms apart from this.
However, for females, other symptoms like an irregular menstrual cycle or other hormonal imbalances can indicate infertility issues.

Understanding Male Infertility
Male fertility is a complex process that requires the proper functioning of various reproductive organs and the production of healthy sperm. Several key factors are necessary for successful conception:
- Healthy Sperm Production: During puberty, the male reproductive organs undergo growth and formation, leading to the production of sperm. Adequate levels of testosterone and other hormones are essential to trigger and maintain this process.
- Sperm Transport: After production, sperm must be carried into the semen through delicate tubes until they mix with semen and are ejaculated from the penis during sexual intercourse.
- Sufficient Sperm Count: The number of sperm in the semen, known as sperm count, plays a crucial role in the likelihood of successful fertilization. A low sperm count can reduce the chances of conception.
- Functional and Motile Sperm: The sperm must be functional and capable of moving to reach and penetrate the partner’s egg for fertilization to occur.
Signs and Symptoms of Male Infertility
Some of the signs and symptoms of male infertility are –
- Pain, lump, or swelling in the testicle area
- Inability to smell
- Gynecomastia or abnormal growth of the breast
- decreased hair on the face or in the body
- Problems associated with sexual function like reduced sexual desire, erectile dysfunction, or difficulty with ejaculation.
Causes of Male Infertility
Male infertility can be due to many factors, which can be medical, environmental, or related to lifestyle issues.
#1. Medical issues
- Varicocele – Varicocele is characterized by the swelling in the veins that drains the testicles. It is the most reversible and common cause of male infertility. The cause of the Varicocele might be unknown but it may be related to the abnormal temperature regulation in testicles. Varicocele results in a reduction in sperm count. Treating Varicocele will help in increasing sperm count and function.
- Ejaculation issues – Retrograde ejaculation happens when, during orgasm, semen enters the bladder instead of the tip of the penis. Various health circumstances, including diabetes, spinal injuries, medication, and bladder, prostate, or urethra surgery, can trigger retrograde ejaculation
- Infections – Some infections can interfere with sperm health or sperm production. These infections might include the inflammation of the epididymis or of the testicles known as orchitis. Most often the sperm can be retrieved but, in some cases, the infection results in permanent damage of the testicles.
- Tumors – Cancers and non-malignant tumors may directly influence male reproductive organs through the glands releasing reproductive-related hormones, such as the pituitary gland, or through unidentified triggers. At some times, male fertility may be affected by surgery, radiation, or chemotherapy to treat tumors.
- Hormonal Imbalances – Infertility may lead from testicular illnesses or an abnormality that affects other hormonal structures including the hypothalamus, thyroid, pituitary, and adrenal glands. There are a number of possible underlying causes for low testosterone (masculine hypogonadism) and other hormonal issues.
- Chromosome defects – Inherited illnesses such as the syndrome of Klinefelter — where a male is born with two X chromosomes and one Y chromosome (instead of one X and one Y) — cause male reproductive bodies to develop abnormally. Cystic fibrosis, Kartagener’s syndrome, and Kallmann’s syndrome are other genetic syndromes connected with infertility.
- Problems with sexual intercourse – These can include the problem of erectile dysfunction, painful intercourse, hypospadias, or psychological problems that interfere with sex.
- Celiac Disease – Celiac disease is a digestive disorder that is caused due to sensitivity to gluten and can result in male infertility.
- Medications – Long-term use of anabolic steroids, testosterone replacement therapy, cancer drugs (chemotherapy), some ulcer drugs, certain antifungal drugs, and some other drugs may impair sperm output and reduce male fertility.
- Prior Surgeries – There are certain surgeries that may prevent you from ejaculation. These surgeries may include vasectomy, hernia repairs, prostate surgeries, scrotal surgeries, and large abdominal surgeries.
#2. Environmental causes
Overexposure to a few environmental elements like heat, toxins, and chemicals can reduce sperm count or sperm function.
- Industrial chemicals – Exposure for a long time to benzene, xylene, pesticides, herbicides, organic solvents, and painting material can result in low sperm count
- Heavy exposure to metals – Exposure to lead and other heavy metals can result in male infertility.
- Radiation or X-rays – Exposure to X-rays for a long time or to any kind of radiation results in a reduction in sperm count.
- Overheating of testicles – Elevation in temperature will result in damage to sperm production and function. Frequent use of a sauna bath can impair your sperm count.
#3. Health and Lifestyle
- Use of alcohol – Drinking alcohol can result in reduced testosterone levels that can cause a decrease in erectile function as well as sperm count. Liver disease caused by excessive drinking can also lead to infertility problems.
- Smoking – Men who smoke have a lower rate of fertility than those who don’t. Passive smoking can also harm male fertility.
- Use of drugs – Anabolic steroids are taken to boost muscle power and development can cause shrinkage of the testicles and reduce sperm output. Using cocaine or marijuana may also momentarily decrease your sperm count and quality.
- Stress – Stress can interfere with the hormones that are necessary for producing sperm. Hence, it can also lead to male infertility.
- Depression – The likelihood of pregnancy is lower if the male has severe depression. It can be because of reduced libido, erectile dysfunction, or inhibited ejaculation.
- Weight – Being overweight can result in a hormonal change that might further reduce male infertility.

There are various treatments for male infertility the options might include surgery treating infections or hormonal treatments.
#1. Surgery
It is often possible to correct a varicocele surgically or to repair an obstructed vas deferens. It is possible to reverse prior vasectomies. In cases where there is no sperm in the ejaculate, sperm can often be recovered from the testicles or epididymis using sperm recovery techniques.
#2. Treating infections
It is possible to cure an infection but it doesn’t always restore fertility.
#3. Treatments for sexual intercourse problems
Counseling and medication can help in improving fertility conditions such as erectile dysfunction or premature ejaculation.
#4. Hormonal treatments
In instances where infertility is caused by elevated or low concentrations of certain hormones or issues with how hormones are used by the body, your doctor may suggest hormone replacement or medication.
#5. Use of ART
ART treatments require obtaining sperm, depending on your particular situation and desires, through ordinary ejaculation, surgical extraction, or from donor people. The sperm is then placed into the female genital tract or used to inject sperm in vitro or intracytoplasmic.
