Last Update: 07/05/2019

If you have been trying to conceive for 12 months without achieving pregnancy, perhaps it is time for you to visit a fertility specialist to have your fertility checked.

In the case of men, the main male fertility test to check whether you produce healthy sperm or not is the semen analysis. Through a semen analysis, seminogram or sperm test, we can learn about a man's sperm count and the quality of the sperm produced.

There exist other ways to check if a man is fertile, such as performing a hormone blood test or a semen culture to determine whether a sample is healthy by observing how it looks like in terms of color, texture, and smell.

Below you have an index with the 9 points we are going to deal with in this article.

How do you get tested for infertility?

To get tested for infertility, couples should visit a doctor who specializes in fertility issues. Once at the doctor's office, you will be interviewed to learn about your medical history and be required some tests to check your fertility. The ultimate goal is to find out what is causing infertility and determine what's the best treatment for you.

A basic male fertility check-up includes basic tests such as a physical exam, to check the overall state of health of the male and his sexual organs, and a semen analysis, to evaluate the quality of the sperm he produces. If the results of the test are abnormal, hormone blood testing may be required to identify the presence of alterations in male sex hormones.

If you have doubts or queries about the results of your fertility tests or the tests you should undergo to have your fertility checked, do not hesitate to ask here: Male infertility and men's fertility forum.

Physical exam

The first test that you will undergo is a physical exam to dismiss the possibility that what is causing you to be infertile are problems of the testes or related with ejaculation.

To this end, the urologist can perform the following exams:

  • Measurement of weight and height
  • Inguinal exploration
  • Genitalia and prostate examination
  • Evaluation of the testis, including testicular size and consistency
  • Testicular ultrasound

The goal is to dismiss the presence of anatomical problems that are causing infertility and evaluate whether the male has some kind of ejaculation problem or disease. If the cause of infertility is not found through this test, the next step is to carry out a semen test.

Semen analysis

A semen analysis, also known as sperm test, seminogram or semenogram, is a study of the sperm parameters that determine the quality of a man's semen sample. For this test to be effective, an abstinence time of between 3 to 5 days is advisable.

The sperm parameters analyzed through a semen analysis are:

Sperm motility
For the sperms to be able to reach the egg and fertilize it, they should move forward rapidly and progressively.
Sperm concentration
It refers to the sperm count per milliliter of ejaculate or in the entire sample.
Sperm morphology
Sperms with abnormal forms will find moving forward more complicated, not to mention the obstacles of the female reproductive tract until they are able to hit the egg.
Sperm vitality
Sometimes, a sperm test shows the presence of dead sperm in the ejaculate, which are obviously incapable of fertilizing an egg. It is important for a high percentage of motile sperm to be available.

Other aspects such as the volume of ejaculate, the pH, or the viscosity are often analyzed as well.

The World Health Organization (WHO) has established a series of reference values to consider as normal the results of a semen analysis. Depending on the semen analysis report, we will be able to find out whether there is a pathology or, conversely, if the patient's sample is within the normal range (normozoospermia).

Should an alteration be detected, we can classify the pathology into different types depending on the parameter that is affected: azoospermia (zero sperm count), oligospermia (low sperm count), asthenozoospermia (low sperm motility), or teratozoospermia (abnormal forms).

Hormone test

If the seminogram comes back with negative results, your doctor may require you to take a hormone test by means of a blood work. This study helps the specialist to determine what is causing the results of the semen analysis to be outside the normal range.

Sperm production occurs in the testis thanks to the action of the male sex hormones, including testosterone, FSH (follicle-stimulating hormone), LH (luteinizing hormone), and prolactin.

So, alterations in the levels of these hormones can affect the sperm production process (spermatogenesis), and therefore the sperm count and quality.

Additional fertility tests for males

When the result of a seminogram is negative or parameters such as the sperm count, motility or morphology are altered, the urologist may perform some additional tests, such as the ones mentioned hereunder:

Sperm DNA fragmentation test

For the sperms to be able to fertilize the egg properly and give rise to a healthy embryo, capable of attaching to the uterus, it is important for sperm DNA not to be fragmented.

A high degree of sperm DNA fragmentation can translate into fertilization problems, as well as early embryonic development failure.

Semen culture

If the semen analysis reveals the presence of more than 1 million leukocytes/ml, a semen culture would be required. Basically, it is a bacteriological study of the sperm.

A semen culture may be needed also if the man has testicular pain or swelling, blood in the semen, or a change in the color or smell of the semen is detected.

If the result of the semen culture is negative, which occurs more often than not, it means that the cause of infertility is not an infection.

Genetic test

By means of a karyotype test, we can analyze the chromosomes of a man to look for the presence of some sort of chromosomal abnormality. This genetic test is crucial and very common in cases of both male and female infertility.

If the progenitors have a genetic or chromosomal abnormality, it is very likely to be the reason why they have not achieved pregnancy yet.

Hypo-osmotic swelling test (HOS)

This test is used to check if the sperm plasma membrane works properly or is damaged. To this end, the sperms are exposed to a hypotonic solution, causing an osmotic imbalance in the cells. This, at the same time, causes the solution to penetrate the sperm and expand volume of the cell, which becomes "swollen".

If the sperm plasma membrane is neither intact nor functional, fertilization cannot occur, hence the importance of the HOS.

Testicular biopsy

It is a surgical intervention whereby small samples of the testicular tissue are removed to check whether sperm production is taking place. It is done when the sperm count is zero, a condition known as azoospermia.

FAQs from users

Does the man's age affect the quality of his sperm?

By Mark P. Trolice MD, FACOG, FACS, FACE (reproductive endocrinologist).

Advanced paternal age (APA) is usually defined above age 35-40 and is associated with decreasing sperm analysis parameters. Men above age 45 have approximately 5 times as long to achieve a pregnancy compared with men less than 25 years of age. Further, there is evidence for APA increasing risk of miscarriage, birth defects, and autism. Men older than 40-45 have a twice as likely risk of an autistic child and five times higher risk of a child with schizophrenia.

Which values are considered normal in a semen analysis report?

By Dr. Joel G. Brasch (gynecologist).

Concentration > 15million/ml
Motility > 40%
Morphology > 4%
Vol > 1.5ml

What is the cost of fertility tests for males?

By Sara Salgado BSc, MSc (embryologist).

The cost of male fertility tests can range from $50-300, although it depends on the clinic chosen. As for blood tests, the price can range from $200-400. In case you require additional tests, an increase of the overall cost should be expected.

Can you check sperm count at home with a microscope?

By Sara Salgado BSc, MSc (embryologist).

Although sperm count plays a major role when determining a man's fertility, there are at-home kits that allow a man to evaluate his sperm count without involving a professional. Some kits contain a microscope that allows couples to examine the count of sperm. Even though this option can be somewhat helpful, we do not recommend this method to evaluate your infertility.

What does healthy sperm look and smell like?

By Sara Salgado BSc, MSc (embryologist).

Indeed, semen color, texture and even smell can provide us with a lot of information about your fertility and health. After ejaculation, we can observe the semen's color, texture, consistency, and smell, and get information on our fertility to some extent.

The color of healthy sperm is normally white or light gray. If it ranges from yellow to even green, you may have a prostate infection and should speak to your medical provider as soon as possible to determine if there is an infection causing your sperm to be non-fertile. In this case, antibiotics may be required.

Yellow can also indicate the presence of urine in the semen. If the color of your semen is pink or reddish-brown, it may be an indication of an inflammation of your prostate and that color is caused by bleeding.

As for the texture/consistency, semen is normally thick after ejaculation. If it changes into a sticky texture, it is likely that a medical condition is present.

How can I know my sperm count?

By Sara Salgado BSc, MSc (embryologist).

As explained above, the best way to find out your sperm count is by visiting a fertility specialist and undergoing a sperm test or seminogram.

However, there's a fertility test available in stores called SpermCheck, which allows you to find out in minutes if your sperm count is within the normal range. It works more or less like a pregnancy test—reading its results is easy, as you get either a positive or a negative result.

Anyway, we always recommend that you visit a doctor to get accurate results.

How can you tell if your sperm is fertile?

By Sara Salgado BSc, MSc (embryologist).

The only way to find out if your sperm is fertile accurately is by means of a semen analysis or seminogram. You can ask your doctor to have your fertility checked whenever you want, although men normally visit a fertility specialist if they have not managed to conceive after one year having unprotected intercourse.

Where can a man go to check his fertility?

By Sara Salgado BSc, MSc (embryologist).

To a fertility clinic or a hospital with an assisted reproduction unit. They should be carried out by a urologist/andrologist that is experienced in the field of infertility.

What can cause a man to be infertile?

By Sara Salgado BSc, MSc (embryologist).

More than 90% of male infertility or sterility cases are caused by sperm abnormalities, including poor sperm quality, low sperm count, abnormal morphology, or a combination between all of them. Other causes that can affect a man's fertility are: anatomical problems, genetic defects, hormonal imbalances, etc.

What male fertility test should be done before marriage?

By Sara Salgado BSc, MSc (embryologist).

Actually, there is no compulsory pre-marital male or female fertility test that must be done by default. However, some couples prefer to be tested for HIV and other sexually transmitted diseases, blood group, fertility, possible genetic and/or chronic medical conditions, etc. But, as I said, this is totally optional and varies from couple to couple.
