Why Sperm Analysis Matters More Than You Think
Male fertility plays a crucial role in conception, yet it’s often overlooked in early fertility assessments. At Marylebone Diagnostic Centre on Baker Street, we offer private, discreet semen analysis that gives men clear, scientific insights into their reproductive health — with same-day testing available.
Whether you’re planning for a family or simply curious about your reproductive wellbeing, this test is one of the most important diagnostics you can take.
What Is a Semen Analysis?
A semen analysis examines the quality and quantity of sperm in a man’s ejaculate. It is the gold standard test to determine male fertility and offers detailed metrics that highlight any issues with:
- Sperm Count (concentration)
- Sperm Motility (movement ability)
- Sperm Morphology (shape and structure)
- Semen Volume
- pH and Viscosity
- White Blood Cells (infection/inflammation markers)
Each of these factors plays a significant role in natural conception. Problems in one or more can reduce the likelihood of successful fertilisation.

What Does It Mean If Something’s Off?
Your results may show irregularities in one or more components. Here’s what they might indicate:
- Low Count: Could signal hormonal issues, varicocele, or past infections.
- Poor Motility: Often due to lifestyle factors, heat exposure, or genetics.
- Abnormal Morphology: Can affect the sperm’s ability to penetrate the egg.
- Low Volume or pH Issues: May indicate ejaculatory duct obstruction or infection.
A semen analysis is often the first step in fertility investigation. Our team at Marylebone will support you with expert advice and options for further testing or treatment if needed.
