Fertility is part of health, infertility is not the norm.
Healthcare can cure or compensate for disease or damage to the reproductive system.
One might argue that any non life-threatening condition need not be addressed. No need for corneal transplants or hip replacements, people can cope well enough without.
But healthcare works within its limitations to restore people to the best healthcare standard possible to improve their quality of life.
So a blocked fallopian tube can be unblocked to restore fertility just as a blocked ear canal can be unblocked to restore hearing. Neither are life-threatening but optimal function can be restored to improve quality of life.
In this scenario every participant begins healthy.
By the end, two formerly healthy women have been caused significant health risk, pain and possible permanent damage, even risk to life. And a child has been created and removed from its mother.
Who is the patient in this scenario?
What health condition is being treated?
Who is receiving treatment?
How are they benefitting?
What is the risk?
Who bears the cost?
