Are there different types of hyaluronidase?

Hi Doctors :) I’m wondering if there are different types of Hyaluronidase and if so what are the names and what are they made from ? My doctor who injected me simply says it’s just “Hyaluronidase “ and will not tell me if it was mixed or diluted! I find this to be very unprofessional. I’m also wondering how long it stays in your system for ? I was told it stays for 5 months , is this true ? Thank you for your time :)
