Mosie is about the size of a tampon, roughly 3.5 inches in length, by .5 inch diameter. The syringe volume is 5.5 ml.
We spent a lot of time researching the most effective and most comfortable syringe we could offer - after working with our own fertility specialist and with a lot of a lot of trial and error - Mosie Baby was created. Now, 4 years later, Mosie has been able to help many people, including those with vaginismus. Feel free to read this review from this Mosie user struggling with vaginismus: https://mosiebaby.com/blogs/success-stories/struggling-to-conceive-with-vaginismus-led-to-mosie-and-new-hope
We hope you'll agree that this is the best syringe for conception on the market.
