Fertility facts

Fully understanding your fertility health will help you decide what to do next.  

Your fertility can be affected by all kinds of factors, including your age, medical history, and even your diet. While some issues can be overcome with a few lifestyle adjustments, others might mean you need some extra help to start or grow your family. 

Understanding fertility health

Usually, we’d suggest having your fertility health checked if you’ve been having regular sex for a year or longer without being able to conceive, or for six months if you’re over 35. It’s also a good idea to get checked out if you have any chronic medical problems, or if you’re taking any medication that you’ve been told could affect your fertility. 

Causes of infertility 

Your fertility can be affected by:


Female fertility declines rapidly after the age of 35, and roughly a third of women between 35 and 40 have fertility problems. This is because egg quality decreases as women get older, which is why some women now consider egg freezing as a way of preserving their fertility until they’re ready to start a family.

Illnesses and conditions

There are all kinds of conditions and illnesses, such as polycystic ovary syndrome, endometriosis, and ovarian, testicular, or genetic disorders, that can affect your fertility – and there are some you might not even realise you have. For both men and women, STIs like chlamydia can also cause serious problems.

Overall health

Being overweight, being seriously underweight, smoking, and drinking too much alcohol can all have a negative impact on your fertility. You can find out more about how to get fertility fit here.

CARE patient

How can CARE help?

At CARE we’ve spent years pioneering tests and treatments, including CAREmaps, pre-implantation genetic screening (PGS) and C4M2, that can help us better understand what might be stopping you from conceiving.

When you come to CARE we’ll look at your medical history, age, and current health and fitness as a starting point to help us decide your next steps. If you haven’t yet had any tests, we’ll then suggest some standard screenings or a fertility assessment. Tests might include:

Depending on what we find we might then recommend other, more specialised tests to look into things further.

Once we have your results you can book an appointment to talk through them with your fertility specialist. They’ll help you to fully understand your fertility and any problems you might have, before explaining what we can do to help.


What should I do next?

Talk to CARE

If you think you might be interested in one of our treatments, or if you’d like to talk to someone at CARE about your options, there are lots of ways to get started:

  • Book in for a free 1-2-1
  • Book a consultation
  • Come to one of our clinic information events
  • Speak to your local clinic to find out more.

You can do all of the above through our contact form or by calling your local clinic.

Ask about NHS referrals

In some areas – and in certain circumstances – you can be referred to CARE for tests and treatments funded by the NHS. If you’re planning to speak to your GP, ask them whether you can be referred to CARE. You can find more about treatment at CARE with the NHS here.

Join our forum

Introduce yourself on our bulletin board and chat to some of our other patients. It can be really comforting to talk to others going through a similar experience, and they might have useful advice for those new to treatment.
