Semen Analysis

Male fertility testing is simple and routine. It is important for men to be fertility tested, as male infertility accounts for about one-third of all cases of infertility.


Semen Analysis Testing

Semen is the fluid that is released when a man ejaculates. Semen carries the sperm in fluids that should nourish and protect it. Semen analysis provides a lot of information about the quantity and quality of both the semen and the sperm it contains. When you attend the clinic for a semen analysis test, the laboratory will check the sample for:

  • How much semen is produced (volume)
  • The total number of sperm in the semen sample (total count)
  • The number of sperm in each millilitre of semen (concentration)
  • The percentage of sperm that are moving (motility)
  • Whether the sperm are the right shape or not (morphology)
  • If antibodies have attached to sperm, making it difficult for the sperm to move properly (anti-sperm antibodies)
  • Whether or you have an infection in your reproductive system


Semen analysis testing does not take long, our laboratory will issue the results to you either the same or next day.

Semen analysis testing costs €120.

Genetic Causes

A low sperm count, or absence of sperm in semen, may indicate a problem with the Y chromosome; in particular Y chromosome micro deletion. Other genetic conditions include Klinefelter syndrome and Kallmann syndrome.


Cryptorchidism is a condition where one or both of the testicles are not found in the scrotum, but instead lie in the abdomen. It is also known as an ‘undescended testicle’. Some men may also be born without testicles, a condition called ‘anorchia’.

Congential Absence of Vas Deferens 

This is a condition where the sperm ducts of a male do not develop properly. Sperm is not carried from the testicles to become part of semen, resulting in azoospermia. It is linked with cystic fibrosis.

Lifestyle Issues 

Use of illegal drugs, alcohol and smoking are all risk factors for reduced fertility.

Sexual Dysfunction 

Many men experience erectile dysfunction. This means they are unable to attain an erection and cannot have penetrative sex needed to conceive. Other men experience problems with ejaculation.


Men who have previously had a vasectomy (an operation to make him sterile and prevent pregnancy) can experience what is called obstructive azoospermia.


A varicocele is a swollen vein on a man’s scrotum which can impact sperm production. 


History of a sexually transmitted infection, mumps or inflammation of the testicles may impair fertility.

Other Causes

Chronic disease such as diabetes and high blood pressure, exposure to radiation, high temperatures, and treatment with chemotherapy are all linked with infertility.

Lifestyle changes can improve semen analysis results.

If the results are returned that there is no sperm in the ejaculate (a condition called “azoospermia”), there are surgical options. See HERE for more details.
