Follicle Stimulating Hormone (FSH) Blood Test

Follicle Stimulating Hormone (FSH) is a hormone produced in the brain and is an essential part of egg production. It stimulates the follicles in the ovaries to enlarge, leading to egg release. Understanding your FSH level during your menstrual cycle can help investigate your potential fertility.


Why FSH?

Common reasons for this blood test are:

  • You are planning to have a baby and want to check if a hormonal imbalance could affect this
  • You are struggling to conceive and want to check your fertility
  • You want a general check of your fertility hormones.

Your blood test

Our phlebotomy-trained professionals will take a blood sample from you. This sample will be analysed in the UK by our authorised partners, TDL. By booking this blood test, you agree for us to share your personal information with TDL in order to process your test. We’ll make sure you consent to this at your appointment too.

Frequently Asked Questions

No, we will send you the results and recommend that you share these with your GP or fertility provider.

It is not unusual for some bleeding to occur under the skin following your blood test and sometimes this can extend a little further around the puncture site.  If this causes you concern, check with your practice nurse. 

Sometimes we cannot get a blood sample from you. This can be for many reasons, such as not being hydrated enough, feeling cold or having another blood test recently. We will always offer you another appointment so we can try again.
