When couples experience difficulties conceiving, semen analysis is often one of the first and most important fertility tests recommended.
Men are just as likely to experience difficulty with their fertility as women. For around half of heterosexual couples who are having problems conceiving, the cause of infertility is sperm-related (HFEA), and a semen analysis provides valuable insight into sperm health and reproductive function.
Understanding what semen analysis involves, what it measures, and why it matters can help remove uncertainty and encourage earlier assessment.
What Is a Semen Analysis?
A semen analysis is a laboratory test used to assess both the quantity and quality of sperm within a semen sample. It is considered the cornerstone of male fertility testing and is usually the first investigation carried out when assessing fertility.
The test helps identify potential issues that may affect the ability to conceive naturally and can guide decisions around fertility treatment.
When Is a Semen Analysis Recommended?
A semen analysis may be advised if:
- You and your partner have been trying to conceive for 12 months without success
- There is a known medical history that may affect fertility
- You are planning fertility treatment such as IVF or ICSI
- You have concerns about your reproductive health or sperm quality
Early testing can provide reassurance or identify issues that may benefit from further investigation or treatment.
What Does a Semen Analysis Involve?
The process is straightforward, non-invasive, and typically completed within a short appointment.
Producing the Sample
The semen sample is usually produced through ejaculation into a sterile container. In most cases, this is done at the clinic in a private room, although some clinics may allow samples to be collected at home under specific conditions.
To ensure the most accurate results, patients are often advised to:
- Avoid ejaculation for 2-5 days before the test
- Avoid excessive alcohol intake before testing
- Inform the clinic about any recent illness or medication use
Once collected, the sample is analysed in a specialist laboratory.
What Does a Semen Analysis Measure?
Several important sperm and semen parameters are assessed during testing.
Sperm Count
This measures the number of sperm present in the semen sample. A low sperm count can reduce the chances of fertilisation.
Sperm Motility
Motility refers to how well the sperm move. The progressive movement is essential for sperm to travel through the reproductive tract and reach the egg.
Sperm Morphology
Morphology assesses the shape and structure of sperm. Abnormal sperm shape may affect the sperm’s ability to fertilise an egg.
Semen Volume and pH
The overall volume and acidity (pH) of semen are also evaluated, as abnormalities may indicate issues with sperm production or the reproductive tract.
Suitable Sperm Parameters for Essential IVF/ICSI Treatment
Suitable sperm parameters for acceptance onto the Essential IVF/ICSI package include:
- No surgically retrieved sperm (PESA/TESE)
- Sperm count of 2 million/ml or above
- Progressive motility above 0%
- Normal forms above 0%
- Semen analysis performed either at Manchester Fertility or a suitable accredited UK laboratory
Why Semen Analysis Matters
Early Diagnosis Can Improve Outcomes
A semen analysis can identify potential fertility issues early, allowing appropriate treatment or lifestyle changes to be introduced sooner.
It Helps Guide Fertility Treatment
Accurate semen analysis results help fertility specialists recommend the most appropriate treatment pathway, whether that involves lifestyle improvements, further investigations, IVF, or ICSI.
It Can Prevent Unnecessary Treatment
In many cases, a semen analysis provides valuable answers quickly and may prevent couples from undergoing unnecessary or more invasive procedures.
What Happens After the Test?
Results are usually available within a few days. If any abnormalities are identified, your fertility team or nurse will discuss the findings with you and explain any recommended next steps.
This may include:
- Repeat semen analysis testing
- Lifestyle advice to improve sperm health
- Referral for further investigations
- Discussion of fertility treatment options
Because sperm quality can vary over time, repeat testing is sometimes recommended to confirm results.
