There's not enough funding for IVF as it is. What there is should quite rightly be restricted to those who have medical issues not those who just want it. Turkey baster DIY doesn't have to cost a lot surely?
As per PP I would be very uncomfortable with a ruling for lesbian couples which paved the way for a couple in which both partners are male to start demanding they have a legal entitlement to rent a womb (or have one rented by the state at no cost to them) which would be totally unethical.
Everyone with a womb has an equal right to attempt to conceive and gestate a child, and there is no need to have sex with a man to do so if that's not your bag.
Everyone with a medical issue that stops their womb from functioning as required should have an equal right to help with that, and I don't think there's an ethical problem with there being gatekeeping to ensure that those applying for such help have done their level best to conceive without medical help.
No one who doesn't have a womb, or doesn't want to use the womb they have, should have the right to borrow or hire the use of another human's body.
The couple in the article are calling for Lesbians to be a special case who don't have to try to see if their biology can do its thing. That redefines fertility treatment from being about fixing medical issues to being about paving the way for any couple of any biological combination to have state-funded assistance to make a baby. That is not a precedent I want to see being set.
