Sperm Decline: How To Improve Sperm Health

Sperm counts worldwide have plummeted by 62 per cent since 1973, according to a recent study published in the journal Human Reproduction Update.

Dr James Hopkisson, Medical Director at TFP Fertility Group, one of the UK’s largest IVF providers and fertility specialists with clinics across Europe, answers questions surrounding sperm count and what factors could help improve sperm health.

What is a semen analysis?

A semen analysis is an assessment of the number, motility and morphology of sperm in what is ejaculated.  It should be carried out in a specialist laboratory and the normal parameters are dictated by a population survey by the World Health Organisation. 

A sample should be ejaculated into a sterile pot provided by the lab, usually after two to three days abstinence, to optimise sperm quality.  The sample needs to be delivered to the lab within an hour of production to be analysed.  If this proves difficult you can do your sample at the Fertility Unit so as not to have the anxiety of bringing the sample in.

What happens if I have low sperm motility or a low sperm count? 

If you have a low count, motility or morphology it is worth repeating 2-3 months later after lifestyle change.  Sperm count can fluctuate so sometimes it is not something to worry about. 

If there are persistent issues with a sperm count then referral to get advice on types of treatment available is required. If there is no sperm in the ejaculate (azoospermia) other tests may be required such as hormonal assessments, genetic tests and a medical examination of the testes including ultrasound.  These will require review by your doctor and referral onto a fertility specialist.  This can either be in the NHS or at a fertility clinic such as TFP Fertility Group.

What does sperm morphology mean? 

Morphology is what a sperm looks like down the microscope. A sperm has a head, a midpiece and a tail. We can look at different parts of the sperm and see if they look “normal”.

What does a normal-shaped sperm look like?

A bit like a tadpole. It should also be swimming in a characteristic way.

Is there anything I can do to improve the health of my sperm?

Yes, there are many:

• Avoid binge drinking alcohol
• Minimise caffeine intake
• Loose fitting underwear
• Avoid long hot baths
• Healthy lifestyle, Vitamin C Zinc and selenium.  L-Carnitene may be beneficial
• Anti-oxidants may also help, but the evidence is not strong
• High protein diets and gym supplements: always be careful and check what is contained in them
• Never use anabolic steroids: although you may want to be beach ready for the summer, they will suppress sperm production and sometimes this is not recovered.

If concerned seek the opinion of an expert, at TFP Fertility Group we have a group of doctors and scientists who can help, advise and reassure you.  Our labs are quality tested and we have andrologists and lab teams that can help provide semen analysis.
