How Can You Recognize the Signs of Male Infertility, and How Do They Affect Fertility?

What Causes Male Infertility?

Pregnancy may be delayed because of a problem affecting sperm production, movement, or shape, or because sperm cannot travel properly through the reproductive system. In some cases, more than one problem may be present, making tests necessary to identify the exact cause.

The main causes of male infertility include:

1. Varicocele: This occurs when the veins around the testicle become enlarged. It may affect sperm production and quality in some men.
2. Hormonal disorders: Changes in testosterone or in the hormones responsible for sperm production may affect fertility.
3. Low sperm production: The testicles may produce only a small number of sperm or may not produce sperm at all.
4. Blocked sperm ducts: A blockage may prevent sperm from reaching the semen even though the testicles produce sperm.
5. Infections: Some infections of the reproductive system may affect sperm production or movement.
6. Genetic causes: Some genetic disorders may affect testicular function and sperm production.
7. Certain medicines and treatments: Some medicines, chemotherapy, and radiation therapy may affect fertility.
8. Lifestyle factors: Smoking, obesity, and the use of certain harmful substances may be associated with poorer sperm quality.

Fertility may also be affected by using external testosterone or anabolic steroids. These substances may reduce sperm production, so you should tell your doctor about any medicines or supplements you use.

What Are the Signs of Male Infertility and Poor Sperm Quality?

If you are looking for symptoms of male infertility, it is important to know that there is no single sign that confirms infertility. Fertility may be reduced without causing noticeable changes, while some symptoms may point to a health problem that deserves evaluation.

The main signs that require attention include:

Difficulty Getting Pregnant

If you have been trying to have a child regularly without using birth control and pregnancy has not occurred, fertility evaluation for both partners may be appropriate.

Medical evaluation is usually recommended after 12 months of regular attempts, or after 6 months if the female partner is 35 or older. Earlier evaluation may be needed if you have a known testicular problem or have previously received treatment that may affect fertility.

Low Sex Drive

Reduced sexual desire may be linked to a hormonal disorder, including a low testosterone level. However, low sex drive does not necessarily mean infertility. It may result from psychological or other health-related causes.

Difficulty Getting an Erection or Ejaculating

Some erection or ejaculation problems may affect the chances of pregnancy, especially if they prevent semen from entering the vagina. Some of these problems may be linked to hormonal or nerve disorders or to chronic diseases.

Changes in Testicle Size or Swelling

Small testicles or a noticeable difference in their size may indicate a problem that requires examination, especially when accompanied by a change in testicular texture or other symptoms.

Varicocele may also cause a feeling of heaviness or mild pain that becomes worse after standing for long periods. New swelling or a lump in the testicle requires medical evaluation.

If you experience sudden, severe testicular pain, especially with swelling or nausea, go to the emergency department immediately. The cause may be testicular torsion, which requires urgent treatment.

Changes in Semen

You may notice changes in the amount or consistency of semen, but these changes alone are not enough to determine sperm quality or the ability to have children.

Semen may look normal even when the sperm count is low or sperm movement is poor. Its volume may also change for reasons unrelated to infertility. Therefore, semen analysis remains the main test used to evaluate these factors.

How Is Male Infertility Diagnosed?

You cannot confirm your ability to have children or diagnose infertility based only on symptoms or the external appearance of semen. Diagnosis requires a medical evaluation that combines your health history, a physical examination, and appropriate tests.

The main tests used to diagnose male infertility include:

Semen Analysis

Semen analysis is one of the most important initial fertility tests. It helps assess:

1. The number and concentration of sperm.
2. Sperm movement and their ability to move.
3. Sperm shape and the percentage of normal forms.
4. Semen volume and some of its other characteristics.

If the results are abnormal, your doctor may ask you to repeat the test because results can vary from one sample to another. One result is not always enough to determine the cause or the chances of pregnancy.

Physical Examination

The doctor examines the testicles and reproductive system for signs such as varicocele, small testicles, or a possible blockage.

The doctor will also ask about your health history, the medicines you use, and any previous surgeries or infections that may affect fertility.

Hormone Tests

Your doctor may measure hormones such as testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) if a hormonal disorder affecting sperm production is suspected.

Additional Tests When Needed

Depending on the examination and semen analysis results, you may need a scrotal ultrasound, genetic tests, or other tests to identify the cause of the problem.

Not every man with delayed pregnancy needs all of these tests. The doctor chooses the appropriate tests based on each individual case.

Is There Treatment for Male Infertility?

Yes. Several treatments may help improve fertility and increase the chances of pregnancy. However, treatment depends on the cause and test results, and there is no single treatment that is suitable for every case.

The main treatments for male infertility include:

Treating Hormonal Disorders in Men

If reduced fertility is caused by a specific hormonal disorder, the doctor may prescribe treatment to restore hormonal balance and improve sperm production.

However, external testosterone should not be used to improve fertility. It may suppress sperm production and reduce the chances of pregnancy.

Treating Varicocele

The doctor may recommend varicocele repair in selected cases, especially when a varicocele can be felt during examination and is accompanied by delayed pregnancy and abnormal semen analysis results.

Surgery may improve some fertility measures in these men, but results vary from one case to another.

Treating Infections or Blocked Ducts

If tests identify a specific infection, the doctor may prescribe appropriate treatment. If the sperm ducts are blocked, surgery may be an option depending on the location and cause of the blockage.

Antibiotics are not routinely used to treat infertility unless there is an infection that requires them.

Assisted Reproductive Techniques

If pregnancy does not occur with other treatments, the doctor may suggest an assisted reproductive technique, such as intrauterine insemination in suitable cases, or in vitro fertilization and intracytoplasmic sperm injection, depending on the evaluation of both partners.

In some cases of azoospermia, meaning no sperm in the semen, sperm may be retrieved from the testicle or epididymis if the condition allows.

How Can Men Improve Fertility?

If you want to support your reproductive health, following a healthy lifestyle may improve some fertility factors. However, it does not replace treatment for an underlying medical cause.

Here are practical steps you can take:

1. Stop smoking: Smoking is associated with poorer sperm quality in some men.
2. Maintain a healthy weight: Obesity may affect hormonal balance and sperm quality.
3. Eat a balanced diet: Include vegetables, fruits, whole grains, protein sources, and healthy fats.
4. Exercise regularly: Regular physical activity supports general health and metabolism.
5. Avoid anabolic steroids and testosterone without specialist supervision: These substances may affect sperm production.
6. Review your medicines with your doctor: Some medicines may affect fertility, but do not stop taking any prescribed medicine on your own.
7. Avoid repeated exposure of the testicles to high temperatures whenever possible: Increased heat may affect sperm production, but the effect varies from person to person.

Remember that sperm production takes several months. Therefore, any improvement after changing your lifestyle or starting treatment may take time, depending on the cause and the nature of the condition.

In the end, signs of male infertility do not necessarily mean that you cannot have children. They may indicate a problem that requires medical evaluation. If you are experiencing delayed pregnancy or notice changes in your sexual health, seeing a urologist or andrologist and having a semen analysis can help identify the cause and choose the appropriate treatment. Early diagnosis may help improve fertility and increase the chances of pregnancy, depending on the nature of the condition.
