What do your ‘Normal’ Semen Analysis Test Results Mean?
You’ve just had your initial semen test results back, and the doctor/receptionist will says ‘yes it was all normal’, without actually giving you the report. Please, always ask for a copy of your semen analysis, it is SO helpful to have the actual document to hand and provides really valuable information. Many semen analysis sheets that I review may be ‘normal’ but are not optimal for fertility.
What is a sperm sample?
A semen or sperm sample is the fluid produced when you ejaculate/orgasm, and should contain sperm, which are the male cells that fertilise a human egg. Samples are collected into a pot, and sent to a lab for assessment. Samples are assessed using basic criteria, and you can usually have the analysis done via a request from your GP.
These criteria, based on reference ranges for male fertility via semen testing, are usually measured against World Health Organisation agreed levels. These have just been republished as until this year the most recent figures used were from 1999!
The criteria give expected ranges for a viable semen sample, so if your results fall outside those ranges – either below or above, then there may be an issue with your semen/sperm.
A basic sperm test usually give a report on all (or some) of the following measures:
Volume (the amount produced for the sample)
Motility, broken down into rapid, slow, non-progressive and immotile
Concentration/count per ml and total for the sample
Morphology, broken down into normal, abnormal, head/mid-piece/tail defects, cytoplasmic droplets
What is a normal sperm sample?
The WHO criteria look specifically at volume, total number of sperm in the sample, concentration of sperm per ml, motility, morphology and pH level, so these are what I am going to discuss in this article.
* There should be a certain volume of semen in a sample, the new range suggests a minimum of 1.5 ml, and up to 5ml is considered within range.
* The total of sperm in the sample should be greater than 39 million, and concentration per ml greater than 15 million.
* Motility will usually be total (all the sperm together) greater than 40%, and progressive greater than 32%.
* pH levels in the sample should be 7.2, anything below this or greater than 8 should be investigated further.
* Finally, morphology or normal forms should be greater than 4%
If a semen sample comes back outside of these ranges you may see notes on the report such as low motility, poor morphology, even azoospermia. These are technical terms which refer respectively to sperm which do not move well, sperm which are not properly formed, and lack of sperm observed. Observations about the pH might indicate infection or urine contamination of the sample, and issues with volume could be indicative of an issue with sperm production including physical obstructions, heat damage from varicoceles etc.
The above are all common, although as I’ve said before, not necessarily addressed, because male factor issues – despite being 50% of the base material for embryos – are not considered until last resort in many cases.
What might be wrong with a sperm sample?
Below I have listed some common causes of poor quality sperm samples. Hopefully, this article will help you understand the issues surround male fertlity better. My job as a reproductive reflexology specialist is to guide you to understanding what’s happening with your sperm, by interpreting your specific results, and then a) use targeted reproductive reflexology (and a holistic approach) to see if we can make changes which may sustain improvements to sperm quality, and/or b) refer you for further testing as necessary, with continuing reflexology and holistic support.
Causes of low semen volume
You might see a low volume (called hypospermia) if some of the sample missed the collection pot, however, other causes can be linked to ejaculation problems such as retrograde ejaculation where semen travels backwards into the bladder, prostate gland cancer treatments, medications, diabetes and hormonal issues. Blockages in the seminal vesicles which deliver the sperm to the penis can be caused by varicocele, infections can also be a cause.
Causes of low sperm in semen samples
Low quantities of sperm in a sample can cause problems with conceiving a child. The reasons for fewer sperm in a sample can include problems with sexual function (low libido, erectile dysfunction), pain or swelling in the testicles, hormone abnormalities, previous injury to the testicles or penis, infections, varicoceles, anti-sperm antibodies (an immune system problem), blockages in the tubules anywhere in the male reproductive system and undescended testicles. Celiac disease, prior surgery and chromosome defects can also be the cause of low sperm counts. Many of these issues can be resolved, discovering them initially may be the hardest part of the problem.
Low motility in semen samples
Causes of poor motility are connected to infections, defects in the sperm DNA, alcohol and drug use, and inflammation. Low motility means that the sperm are not moving well – either going in circles, not moving fast enough or failing to move forward. As with poor morphology, low motility has effects on the ability of sperm to move to the fallopian tubes where the egg is waiting, and thus has a negative affect on male fertility. The corkscrew motion of a well formed sperm is much more effective in the long journey to fertilise an egg, so you can see again that good quality sperm making forward progress are likely to be better at moving through the uterus to their destination. Reducing inflammation, treating infection, and changing lifestyle habits can all have a positive effect on motility.
Semen pH levels
Semen is usually slightly alkaline with a normal pH range between 7.2-8.0. The acidity or alkalinity of a semen sample can indicate issues or infections – which are often invisible, additional screening often reveals these and then treatment with antibiotics and supplements can help to improve the levels. High or low semen pH can cause sperm death. It can also impact the ability of the sperm to swim and be able to penetrate the egg.
Causes of poor morphology
Morphology issues can be caused by heat damage, which include external heat such as use of saunas, heated car seats etc., or damaged caused by varicocele (lumpy collections of veins on the testicles), infections and lifestyle choices including drug and alcohol use. Some prescribed medications can also have a negative effect on the morphology of sperm, so it’s worth checking that any drugs prescribed are fertility friendly. Well formed sperms should have an evenly formed head, mid-piece and tail. Each part has a job to do: the head contains the genetic material, the mid-piece is the engine and the tail provides the movement towards the egg. If morphology is classed as poor, then the sperm may have missing or partial tails, wonky heads, and mid-piece defects, which can cause issues with actually getting into the fallopian tubes, egg penetration, and then faulty fertilisation, which can lead to poor implantation rates and contribute to chemical pregnancies and early miscarriage.
Red Flags for Sperm Quality and Quantity
Red flags which can contribute to issues of sperm quality and quantity include:
– Drugs (including prescriptions and steroids)
– Infections (can be invisible)
– Nutritional deficiencies
– Shift work/poor sleep
Being aware of the issues surrounding your sperm sample can help you to understand where you can make positive changes to improve it. There are of course lots of things that can affect sperm quality, including physical issues but the above are very COMMON and many can be resolved with the right advice and support.
You may need additional testing or screening, or you may just need to make changes to your lifestyle. I expect to work with you for a minimum of 3 months, as this is when I see the best results for improvements with previous clients. Are you ready for the next step? If you have received a less than positive semen analysis, or have been told that you have a normal result but are still having problems conceiving, then book a call with me today.
