I’m in the USA where some sperm banks have the option for storing your own sperm for personal use. They still made me jump through a bunch of hoops including a medical exam, lots of sti testing, offensive questions about my sexual history, and then it costs money. It definitely wasn’t as accessible as I was hoping. The whole process is highly biased towards donors, who have to jump through even more hoops. Places that do it often do have an option for trans femmes or men to store for personal use, but it’s not nearly as common as egg freezing. Most of the places I looked into didn’t even acknowledge that someone might want to store their sperm at all. There’s this implicit assumption that people with sperm are fertile and will remain fertile so why would they want to store their sperm. One of the gotchas was I found a lot of the places that make it easy to store your sperm don’t store it locally. One place for example sent all long term storage to texas, which isn’t ideal in the current political climate. The one’s that store locally are just hard to get in, at least in my experience. Some universities do it too, specifically for trans femmes, but they tend to have really long waits for an appointment.
