Which size MCUK should I buy?
Choose the right size MCUK for you by following the simple guidelines below:
Choose size A if you:
Are 30 and over
Have given birth vaginally at any age
Choose size B if you:
Are under 30 and have not given birth vaginally
The size you choose
– is related to your childbearing history and your age as these can affect pelvic floor tone
– is not related to menstrual flow
Size A is 3mm bigger than size B – a small difference but it is important!
If you’re not sure which size to go for, please get in touch with our Advice team.
- Size A measures 46mm in diameter and 50mm in length.
- Size B measures 43 mm in diameter and 50mm in length.
Both sizes have a stem 21mm long, which you can trim to the length that is right for you.
