It’s rare for further information or testing to be offered to try and ascertain the cause of the suboptimal semen analysis, meaning the couple continue towards fertility treatment with no other help or focus on the man.
Unfortunately, many couples go through these limited investigations and often end up with the dreaded “unexplained infertility” diagnosis. But my question is whether it is actually “unexplained” or simply “un-investigated”.
It is well documented that the likelihood of the issue sitting with the man is roughly equal to that of it sitting with the woman, and that male factor infertility is responsible in more than half of cases where a couple requires IVF3. Yet, despite these statistics, most couples still head into fertility treatment with only a basic semen analysis under their belt.
Could there be more testing for men?
Although still an area of debate among some fertility clinicians, there are further tests and examinations that could be considered for men, some of which show promising data in male infertility aetiology diagnosis:
- Testicular imaging for genito-urinary anatomy
- Serum hormone profile
- Physical examination
- Genetic and genomic tests
- Seminal oxidative stress and reactive oxygen species testing
- Sperm DNA fragmentation
These tests could help identify other, easily treatable, causes of infertility that are unlikely to get picked up on a semen analysis, such as:
- Varicocele (an enlarged vein in the scrotum): Present in around 40% of men who are struggling to conceive, varicocele is associated with impaired sperm quality and sperm DNA fragmentation4. However, this seemingly benign condition is often disregarded by many clinicians and isn’t routinely checked for.
- Oxidative stress (overproduction of free radicals in the body): Another common issue that gets missed but could be easily rectified with the right investigations, treatments or some simple lifestyle and diet changes.
By missing opportunities for further tests and not investigating the man more thoroughly, we run the risk of putting women through unnecessary treatment.
It seems crazy to go into something as invasive, expensive and emotionally charged as IVF without investigating both parties fully, yet this is happening regularly.
The impact fertility treatment has on couples can never be underestimated.
For men specifically, depression, low mood, and loss of libido are all common issues going through fertility treatment, as well as the profound effect it has on them and their relationships. However, there is considerably less support available to men, which could be attributed to the outdated view that they “have the easy bit” or that they just need to “man up”.
Men need support too, in fact when men are given the opportunity to talk and are invited to be part of the conversation many will open up and be more honest about the struggles they’re facing.
Fertility education is crucial for both men and women, and it’s time we helped men get a better understanding of their fertility and the choices they have, because there is so much more out there for them if they know where to look. However, this works both ways. Good education and more thorough testing are needed, and if men were to be offered more comprehensive tests from the very beginning, it could completely change the treatment pathway for many couples.
It’s not just about having a few extra tests. It’s about the right emotional support coupled with the right medical support.
For this, we need to look at the patient pathway and how to better support men through the journey. This starts with a clear referral pathway from GPs, which currently only exists in extreme cases, as well as a focus on the research into the impact sperm have on fertility outcomes, and a push to recruit or train more Urologists with male fertility expertise.
I would always urge couples to ask for clear guidance on testing to ensure they are fully informed, that both individuals are being properly investigated, and that their voices are heard.
