Men's Fertility & Male Infertility Clinic London
When pregnancy is taking longer than expected, it is important to assess both partners. Male factors can contribute to fertility difficulties, either on their own or alongside factors affecting a female partner. A straightforward assessment can help identify what may be affecting sperm health and whether treatment or further support may be appropriate.
Our consultant urologists provide discreet, supportive care for men with fertility concerns in London. We take time to understand your circumstances, arrange appropriate investigations and explain the next steps clearly.

Understanding men’s fertility
Fertility difficulties can affect couples for many reasons. Male factors may relate to sperm production, sperm quality, hormone levels, a blockage affecting the transport of sperm or lifestyle factors that can influence fertility.
A semen analysis is usually an important first step. This test assesses key features of a semen sample, including the number of sperm, how well they move and their shape. A consultant assessment can then help identify factors that may be contributing to a result outside the expected range.
Some causes of reduced fertility can be treated or improved. Others may require more detailed investigation or support from a fertility specialist. An unexpected result does not provide the whole picture, and it does not necessarily mean that there are no options.
We understand that fertility concerns can feel personal and difficult to discuss. Our approach is discreet, practical and focused on helping you understand what the findings mean for you.


What can affect men's fertility?
A number of factors can influence male fertility. Assessment helps identify which may be relevant in your situation.
Sperm quality
The number of sperm, their movement and shape can all affect the chance of conception. In some cases, the integrity of sperm DNA may also be relevant.
.
Varicocele
A varicocele is an enlarged group of veins in the scrotum. It can be associated with reduced sperm quality in some men.
Blockages and previous surgery
A blockage in the reproductive tract, or a previous vasectomy, may prevent sperm from reaching the semen despite ongoing sperm production.
Hormonal and lifestyle factors
Hormone levels, weight, smoking, alcohol intake, medication and general health can all have an influence on fertility.
How we assess male fertility
Assessment begins with a discussion about your medical history, lifestyle, previous fertility history and any concerns affecting sexual or reproductive health.
Consultation and examination
Your consultant will discuss your circumstances and may recommend an examination to check for physical factors that could affect fertility.
Semen analysis
A semen analysis is a key fertility test. It assesses sperm count, movement and shape, helping to build an initial picture of sperm health.
Hormone testing
Blood tests may assess testosterone and other hormones if indicated.
Further tests where needed
Depending on the results, further investigations may be recommended. These can include hormone blood tests, imaging or more detailed assessment of sperm quality.
From assessment to treatment
The findings from your consultation and semen analysis will guide the next steps. Not everyone needs the same tests or treatment, and your care will be tailored to the factors that may be affecting fertility.
Where an underlying cause is identified, treatment may focus on that cause. This could include addressing a varicocele, considering the effects of previous surgery, reviewing hormonal factors or supporting changes that may benefit overall health and sperm quality.
If assisted conception is being considered, your consultant can discuss the appropriate route and coordinate care with fertility specialists where needed.
Our men's fertility services
Assessment starts with the most appropriate initial tests, then builds only where further information is needed.
Semen analysis
A semen analysis assesses the number, movement and shape of sperm. It is often the first investigation for men with fertility concerns.
Sperm DNA fragmentation testing
This test looks more closely at the integrity of sperm DNA. It may be considered when fertility difficulties remain unexplained or there have been recurrent problems with conception.
Varicocele repair
A varicocele can sometimes contribute to reduced sperm quality. Your consultant can assess whether it may be relevant and discuss treatment options where appropriate.
Surgical sperm retrieval
For some men, sperm may be retrieved directly for use in assisted conception, such as IVF. Your consultant will explain when this may be considered and whether referral to a fertility specialist is needed.
Vasectomy reversal
Vasectomy reversal is a microsurgical procedure that may be considered by men who have previously had a vasectomy and now wish to conceive.
