Semen sample and semen analysis

Why do a semen analysis?

Male factor infertility contributes to 40% of cases of infertile couples. The presence of abnormal sperm parameters, found during a semen analysis, is used to diagnose male infertility. Although we are able obtain a lot of useful information from a semen analysis, the quality of one sample can vary from the next and thus a repeat analysis performed by an experienced embryologist at a Medicus clinic may be requested.

What is being examined?

Diagnosing male infertility involves a number of steps. The findings of an initial semen analysis can be used to carry out further investigations including a general physical examination, hormone profile and genetic testing. This will allow us to find potential causes, and provide you with advise on conceiving either naturally or with help of assisted conception.

Here at Medicus, we provide you with accurate and reliable semen analysis results. If necessary, these results can also be used to come up with a plan to potentially improve your sperm quality. Below are a number of important sperm parameters that are known to effect fertility.

Factors affecting male fertility

  • Concentration
  • Motility
  • Semen volume
  • Round cell concentration
  • Degree of DNA damage withe the use of the Sperm Comet test
  • Viscosity
  • pH of semen

What do I do?

Ideally we recommend an abstinence period of 2-3 days before the test. Below we have outlined the process step by step.

In certain circumstances we may recommend a further in-depth analysis known as the sperm comet test. This test examines the degree of sperm DNA damage and is perfomed in collaboration with the British lab Examen. Read more about the sperm comet test here.
