I’m trans in the US. After insurance I pay about $300 to $400 every 3 months for blood tests and a follow up. My meds cost me an additional $90 for 3 months as well. They are my hormones and another medication unrelated to me being trans. I get my meds at a local independent pharmacy, so they are relatively cheap. I used to get them at a large chain pharmacy and they were about twice as much there.
I also used to work as a cashier at a pharmacy. I once had to ring someone up who was paying over $3,000 for some cancer medication. It also wasn’t uncommon to see people paying around $500 for medications that they need to be alive.
There’s an in development technology called in vitro gametogenesis (IVG) that would allow same sex couples as well as infertile people to have biological children. It’s been in the works for over a decade and as far as I am aware has not yet been tested on humans.
