Is the female to male transition funded by the NHS? Parts of it?
Yes. The sperm was purchased, the embryo creation and Implantation I believe was done by a fertility clinic funded by the NHS in F's area, presumably under the same post code literary as everyone else.
The cost of the sperm was a source of complaint as shown in the documentary.
How did the man called Freddy get pregnant?
Not through artificial insemination but IVF, so eggs were harvested and fertilised by fertility Dr with the sperm of the sperm donor of choice by F, and at the time F's partner, as shown in the documentary available on BBC iPlayer I think, entitled Seahorse.
Why would someone pregnant take hormones?
F came off the hormones prior to the IVF, as it was about 10 or 11 days after getting the GRC, F must have been off the hormones for a few months I'm guessing. Odd that after getting a GRC the priority wasn't changing medical NHS records noting F for Female to M for (legal) male, but instead the priority was becoming pregnant.
An FTM in America, who knows F, had to change their medical insurance records from an M back to an F for the purposes of having maternity care covered for their pregnancy.
Are hormones like the contraceptive pill dangerous to a foetus?
Yes, as shown by PP, I imagine that was the advice from Drs and that why F came off them. F has said on F'a social media that hormones don't affect your fertility but does add a disclaimer to you tube videos etc. Viewers or followers who appear to be quite young see F as an inspiration as they themselves hope to follow in F's footsteps and have a biological child of their own one day, even though IIRC, one young person was already on puberty blockers.
Why this was aired on prime time radio?
This was in direct response I believe to the discussion around whether only women have a cervix. The BBC invited F on as an example of someone who is legally male but who is biologically female and has a cervix as F isn't an FTM person who has had an elective surgery to remove their vagina, womb and ovaries. F retained them after the birth of son SJ to have another baby. F Is pregnant again following an miscarriage at the end of last year.
I remember a scene from Seahorse where F had removed the label or crossed off the word woman I think, on the pack of folic acid as it was triggering.
