I think the crux of
@JB007's question/remarks was surprise that your wife was issued an EUSS Family Permit at all.
Normally, at least under EU law before Brexit, there is a sharp divide between family members of dual British-EU citizens who were naturalised in the UK after having acquired PR under EU law and those of purely British citizens (such as those born in the UK), who have to meet much more onerous requirements (and considerably higher fees, in the '000s) for immigration to the UK.
Did you disclose that you acquired your British citizenship by birth in the UK, rather than by naturalisation, when applying for your wife's Family Permit? I think that that may have resulted in a different immigration decision to start with.
To
@JB007, assuming that the OP disclosed his dual citizenship, the OP's application may have been considered under the
Surinder Singh route, as
Lounes is plainly not applicable (to the OP,
Lounes is the case law that applies to dual British-EU citizens who naturalised in the UK;
Surinder Singh is the case law that applies to British citizens that exercised treaty rights in the rest of the EU while simultaneously living with non-British family members).
Anyway, returning back to the topic, your options have been listed in posts above. As it stands, your wife and you will need to pay for fertility treatments on the NHS and you may well want to look at treatment abroad.
Be aware that as the NHS is under pressure for funding, one of the ways that the government is funding it is by pressuring the NHS to bill anybody using NHS services who is not legally entitled to it. See
this thread, where a British citizen and their non-British spouse were billed for the fertility treatment years after the treatment and after they had paid the Immigration Health Surcharge that is payable (@£625 per year of the granted visa) by non-British spouses of purely British citizens. Likewise, visitors to the UK get billed @150% of the NHS cost for any non-emergency care in the UK. See
this thread for a discussion on that theme.
As an aside, a purely British citizen would be paying about £3000 for a 2.5 year spousal visa (~£1000 for the application + ~£1800 for the Immigration Health Surcharge), which they'd have to pay twice, for the five year spousal visa route and then about £2500 for ILR at the end of the five years.
