The Fertility Full Picture: What Blood Tests Can Really Tell You

This week, I’m joined once again by my lovely former co-host and friend, Kate Davies.

You might remember Kate as the science bit of The Fertility Podcast, an independent fertility nurse and all-round champion for women’s health.

These days, she’s got a very fancy title as Vice President of Medical, Women’s Health and Longevity at Ultra Human, and also works as Clinical Lead for One Day Tests, who’ve been a previous sponsor of the pod.

In this episode, we’re diving into what blood tests can really tell you about your fertility and overall health.

Whether you’re just starting to try, have PCOS, or have been on your journey for a while and still don’t have all the answers, this one’s for you.

Kate and I talk about:

  • What your blood tests can (and can’t) reveal about your fertility
  • How often you should get your bloods checked
  • Why it’s so important to monitor cholesterol and glucose if you have PCOS
  • The key tests to ask for if you’ve got unexplained infertility such as thyroid, vitamin D, and prolactin
  • How to use your results to advocate for yourself, especially if you’ve been dismissed before
  • And yes, we even go through my blood test results from One Day Tests
  • Kate also shares what she’s been working on with Ultra Human, including the fascinating world of biometric health tracking.
  • She also introduces something called the Havening technique, a research-backed way to help manage stress and anxiety that’s well worth looking into.
