Do you know what a semen analysis report actually looks like when it arrives? It is usually a single page of numbers with the reference ranges printed alongside each one of them. At any male infertility clinic in Noida Delhi NCR the mistake which we see most often is patients deciding for themselves what all of those numbers mean before a specialist has had any chance to explain them in context. This guide walks you through each of the parameters, what it is measuring and how it should be interpreted, because the numbers themselves matter considerably less than understanding what they are genuinely telling you.
What Parameters Does a Semen Analysis Measure?
| Parameter | What It Measures | WHO Lower Reference Limit |
| Volume | Total ejaculate volume | 1.4 mL |
| Sperm concentration | Number of sperm per mL | 16 million/mL |
| Total sperm count | Concentration × volume | 39 million per ejaculate |
| Total motility | % of sperm showing any movement | 42% |
| Progressive motility | % moving forward in a straight or curved line | 30% |
| Morphology (Kruger strict) | % with normal head, midpiece and tail | 4% |
| Vitality | % of sperm that are alive | 54% |
A standard semen analysis covers six core measurements, and the WHO 2021 reference values are the clinical benchmark which is current:The thing to note is that a result which falls below the lower reference limit in any of these parameters does not mean infertility. What it means is that your sample sits in the lower range of a reference population, and that population includes men who have gone on to father children.
What Does Each Parameter Actually Mean?
Concentration and Total Count
Concentration tells you how many sperm there are in each millilitre of your ejaculate, while the total count multiplies that by the volume in order to give you the fuller picture. Both of them matter, because a low volume sample which has a high concentration can still have a perfectly normal total count, and the reverse is true as well. Anything below 16 million/mL gets classified as oligospermia, whereas zero sperm in the ejaculate is azoospermia.
Motility
Total motility covers any movement at all. Progressive motility, however, is the figure which matters clinically, because it measures the sperm which are actually swimming forwards, and that is what is required if they are going to reach an egg and fertilise it. Poor progressive motility is called asthenospermia and it is one of the most common causes of male factor infertility there is.
Morphology
Morphology is the parameter which is misunderstood most of all. The Kruger strict criteria will only classify a sperm as normal if the head and the midpiece and the tail all meet precise dimensional criteria. So a result of 4% normal means that 96% of your sperm are morphologically abnormal, which sounds alarming when you first read it but which sits entirely within the normal reference range. Moreover, isolated low morphology alongside a normal count and normal motility rarely prevents conception.
DNA Fragmentation
A standard semen analysis does not include DNA fragmentation at all. A sperm DNA fragmentation index test, or DFI test, is a separate investigation altogether, and it is typically recommended in cases of recurrent miscarriage, of unexplained infertility, or of repeated IVF or ICSI failure. High DNA fragmentation is able to affect both your fertilisation and your embryo quality even in the cases where the standard parameters are looking completely normal.
What Should You Do With an Abnormal Result?
- A single abnormal semen analysis should always be repeated, because illness, fever, stress or a prolonged abstinence period can all affect one sample very significantly
- It is recommended that the repeat is timed at least 74 days after the first one, which allows a full sperm production cycle to complete itself
- Mild abnormalities in one or two of the parameters often respond to lifestyle changes, which means reducing your heat exposure, addressing any nutritional deficiencies and stopping anabolic steroid use
- However, the significant abnormalities, and azoospermia or severe oligospermia particularly, warrant specialist investigation which includes hormonal blood tests, a scrotal ultrasound and genetic testing
What Happens Next at a Male Infertility Clinic?
A semen analysis is your starting point rather than the conclusion. At a sperm freezing clinic in Noida Delhi NCR the analysis also guides whether banking is going to be viable for you and what the post-thaw quality is likely to look like. The result is what shapes the clinical conversation, meaning whether your treatment should be starting with IUI, or moving directly across to ICSI, or investigating the underlying cause before any assisted reproduction happens at all. At Embryologist.co.in we review every semen analysis alongside the male partner’s own history before we recommend any next steps, because at a male infertility clinic in Noida Delhi NCR a number which has no context around it is not a diagnosis.
