While there are no hard and fast rules for selecting a size, model selection is generally based on childbearing history. Many other factors, such as anatomy, age, and pelvic floor tone may also influence your cup size selection.
The following is a guide to selecting a suitable model;
Sizing is a guide only. Many women who have had children will still be able to successfully use a Model 1, and vice versa. So, please also consider the other factors below in conjunction with childbearing history and age.
Your cervical position may also influence your selection of the model number and/or your ability to successfully use a menstrual cup. Your cervix may move at different stages of your cycle, so it’s a good idea to check your cervical position at the beginning, in the middle, and at the end of your menstrual cycle to get a good understanding of your overall cervical position.
To determine your cervical height; wash your hands, then insert your index finger into your vagina to locate your cervix. Your cervix is a bump, which feels a bit like the end of your nose, but is shaped like a donut. Thoroughly wash your hands.
If you consistently feel your cervix sitting just inside the vaginal opening or when you have only inserted the tip of your finger up to your ‘first knuckle’ (or the bend in your finger just below your fingernail), you most likely have a low cervix and a Model 4 JuJu Cup may be the most suitable for you. The Model 4 JuJu Cup is better suited to shorter vaginal canals as it has a shorter body and stem when compared with other JuJu Models. Please only choose this model if you are sure you have a low cervix throughout your cycle as the removal of this cup may be more difficult if you have a normal to high cervix. In most cases, the Model 4 JuJu Cup is not recommended for young girls or virgins.
If you are unable to reach your cervix or need to insert your finger past the middle bend in your finger before you can feel your cervix, you most likely have a high cervix and may like to consider the Model 3 JuJu Cup. The Model 3 JuJu Cup has a longer body, which makes removal easier for women with a high cervix and longer vaginal canal.
Some women experience a loss of pelvic floor tone due to hormonal changes and/or age. In this case, a Model 2 may be a preferred choice. A Model 4 should be considered if there is a loss of pelvic floor tone in conjunction with a low cervix.
If you have good pelvic floor tone, practice regular Kegel exercises or other activities, such as Pilates, yoga or dance, you may wish to consider a Model 1 regardless of your childbearing history and age.
If you have had corrective surgery, such as vaginoplasty or perineoplasty, you may want to consider a Model 1.
A Model 3 is recommended for women who have good pelvic floor tone in conjunction with a high cervix.
If you have lost some pelvic floor tone and have a low cervix, you may wish to consider a Model 4.
This Model should only be chosen if you are confident with removing a menstrual cup and are sure you have a low cervix.
A Model 1 is recommended for virgins and sexually active young women.
A Model 3 is recommended for virgins and sexually active young women with a high cervix/long vaginal canal.
If you have a petite or small build, you may wish to consider a Model 1 JuJu.
If you have a larger build, you may wish to consider a Model 2 JuJu.
