understand how to increase male sperm quality

Learn to Interpret Semen Analysis

For couples in the UK, poor sperm quality is the primary cause of approximately 20% of fertility problems. A further 25% of couples have trouble conceiving at least partially due to male sub-fertility. Evaluating semen and sperm quality is therefore the first and most obvious stage in trying to understand the cause of male sub-fertility.

The second stage is to look how to improve fertility. In many instances there is a range of medical options. However, focusing on good nutrition and certain nutrients can naturally improve fertility, plus enhance overall health and well-being.

What is Semen Analysis?

Healthy spermatozoons, floating to ovuleThe most effective way to determine the health of sperm is through a detailed analysis of a fresh semen sample. Results from semen analysis can help to identify specific fertility problems and steps that can be taken to improve fertility.

Although semen may be released in high volume, only 5% is made up of sperm. The remaining semen contains a range of fluids that are secreted throughout the genital tract. The highest percentage of sperm is concentrated within the first stage of ejaculation. This sperm is also the most mobile and more likely to fertilize the egg.

It’s important to understand that a semen analysis isn’t a complete fertility assessment. It’s not possible to assess all aspects of sperm function, such as the ability to find and fertilize an egg for example.

Also, if the results indicate poor fertility, it doesn’t necessarily mean that natural conception isn’t possible. The ability to conceive will decline with increasing semen defects, although in most instances, there are steps that can be taken to improve semen health.

What actually happens?

The number of sperm (concentration), their shape (morphology) and movement (motility) are evaluated, as well as characteristics of the fluid, such as volume, white blood cell count and antibodies.

It’s important to mention that semen quality can be very variable between samples. For this reason, two or three samples are required to get an accurate analysis of semen quality and fertility. These samples should be provided several weeks apart.

Also, illness can impair semen count and function. It can take several months for semen quality to return to normal, especially after a high fever. In this case, specimens should be provided after a few months to ensure a more accurate result.

The figures below summarise the normal range for each of these parameters.

  • Sperm Concentration >20 million sperm/ml.
  • Sperm Morphology >15% normal forms
  • Sperm Motility >50% with forward movement
  • Sperm Antibodies <50% sperm with adherent particles
  • Semen Volume >2.0 ml.
  • White Blood Cells <1 million cells/ml.

Understanding Semen Analysis Results

Sperm Concentration

high quality ingredientsSperm concentration or count is determined by how many sperm are present within each millilitre of semen. A concentration in excess of 20 million sperm per millilitre is considered a healthy sperm count. Any figure below this is classified as a low sperm count (oligozoospermia).

If no sperm is found in the analysis it’s possible that there is an obstruction preventing sperm flow or an absence of sperm production. Termed azoospermia, this medical condition affects approximately 2% of the male population.

Sperm Morphology

The ability to fertilize an egg is partly determined by sperm morphology. During semen analysis, sperm is expertly analysed under a microscope to assess tail, middle and head shape and proportions.

In humans, the ideal sperm shape, defined as ‘normal’ sperm, is not produced in high concentrations, thus the lower limit of 15% normal sperm is considered acceptable. Once the percentage of normal sperm falls below 15% fertility also declines. Men with a normal sperm percentage of less than 5% will find conception especially difficult.

Sperm Motility

male infertilityAlthough low sperm count is the most common reason for poor fertility, low sperm motility (asthenospermia) can also be a problem. Often these two characteristics occur together, making conception extra challenging.

A man is considered fertile by the World Health Organization (WHO) guidelines if he has a minimum “progressive motility”, i.e. grade a+b. of 32%, equivalent to 4.8 million/ml of semen (minimum WHO requirement sperm count of 15 million per ml x 32%). Vitality must be a minimum of 60% live spermatozoa1.

Factors that can affect sperm motility include structural problems associated with the tail, sperm death (necrospermia) and autoimmunity against sperm.

Sperm Antibodies

This condition accounts for approximately 6% of male infertility. Sperm autoimmunity occurs when the body’s immune system attacks sperm as part of its natural defence mechanism against foreign organisms and substances.

Although sperm are normally protected from the immune system, some men produce antibodies that target sperm and reduce their lifespan. They attach to the surface of the sperm, reducing motility and the ability to penetrate the egg.

These antibodies can develop following some form of testicular trauma or surgery, such as a vasectomy. In many causes it isn’t possible to determine the trigger for the development of sperm antibodies. A simple immunobead test is done during semen analysis to detect concentration of antisperm antibodies.

Semen Volume

counselling is important before you start fertility treatment The volume of semen produced is measured to determine if there is a blockage of the seminal vesicles. Volumes less than 2 millilitres may indicate an obstruction preventing sufficient sperm concentration within semen and reducing fertility.

The most common cause of low semen volume is hormone imbalances. As men age, a decline in male sexual hormones will lead to the body producing less semen. Nutritional deficiencies, illness, injuries to the testicles, and infrequent sexual activity also reduce semen volume.

White Blood Cell Count

A high white cell blood count (greater than 1 million cells per millilitre) may be indicative of a genital tract infection which can damage sperm. Even though there may be no noticeable symptoms of an infection, a high white blood cell count will warrant further investigation and a possible course of antibiotics.

Other Semen Measurements

In addition to assessing white blood cell count, sperm vitality is also measured. A low percentage of living sperm can also suggest an infection or problems moving through the genital tract.

pH and fructose levels are also measured. Acidic semen (low pH) and/or the absence of fructose may suggest a blockage within the seminal vesicles and an alcaline semen (high pH) could indicate an infection. A pH between 7.2 and 7.8 is considered healthy.


the male menopause is called andropauseSub-fertility in men is very common and can be a source of anxiety. Undertaking a semen analysis will help to identify any problems with sperm production and sperm quality. Although semen screening can’t identify all potential causes for sub-fertility it will highlight the most common causes, such as a low sperm count, poor motility and morphology problems. By understanding the exact condition, it’s possible to take steps to improve fertility.


Take Action

Whether your semen has already been found suboptimal OR you have recently decided for a baby, you can take action immediately. Small simple changes will help improve your swimmers and maximise your current chance of pregnancy:



fertility boost menMale fertility supplements are free of side effects, become effective after three to six months and are proven to increase sperm count by up to 215%, ejaculate volume by up to 33% and sperm motility by up to 23%2. Finally, they are relatively affordable. Whilst a varied diet is essential, supplements are able to deliver key nutrients in the required quantities more effectively and efficiently than any regular diet.

Supplements are therefore recommended for the initial treatment of asthenospermia (low motility) and oligospermia (low sperm count). A detailed yet easy to read paper summarising several studies was written by Steven Sinclair’s Male Infertility: Nutritional and Environmental Considerations.

      Dear Mohan,
      generally spoken we are a bit confused why you did not receive a proper and in-depth explanation from your physician. To us it looks like the sperm density is low or on the edge. According to new WHO standards it´s OK (above 15 Mio per ml), according to the previous standards of WHO it would be a bit low. You should verify the PUS Cells, which are white blood cells. It could mean that there is an infection. But please verify this with your physician.
