Are these two men not entitled to be parents?
No they are not, because no one is.
To the earlier point if the surrogate mother not needing to go to NCT classes as she will already have her own children. That's likely, however legal proposals will mean this isn't a requirement and there is an increase in private surrogacy arrangements since the birth of Facebook. (Mostly young Nigerian childless women as far as I can tell, and the laws in Kenya are being revisited for good reason I assume).
With these two men I hope their "special friend" already has children and they paid for her expenses as is legal, and no more as that would be paying for a service. Gifts and holidays are permitted but then it's a grey area as to whether it is transactional and that would be human trafficking...
I also hope that if there was another woman involved, the woman who provided the egg for the pregnancy (assuming it was a different woman so her own children are not related to Lucille) then I hope she is ok and didn't suffer from OHSS or any subsequent health issues.
Perhaps if the NCT are widening their scope to include support for surrogacy they should include the women who donate their eggs. Many of those women are childless and don't need support through childbirth classes but could receive therapy to come to terms with what they have given away. Perhaps NCT could advocate for long-term peer-reviewed research into OHSS and the after effects and maybe even see if IVF has constructions to reproductive cancers or early menopause?
If the NCT do what Stonewall did and widen their remit of services so to stay relevant and receive funding then we can expect more of this.
