Alabama lawmakers are considering legislation that would protect in vitro fertilization, after a State Supreme Court ruling last week led some clinics to halt I.V.F. treatments and left many women in limbo.

The ruling, which declared that frozen embryos should be legally considered children, set off a scramble among leaders in both parties to preserve access to a crucial reproductive treatment for families who have struggled with infertility and for L.G.B.T.Q. couples who are seeking to have children.

The court’s ruling, handed down by an 8-to-1 majority, applies only to three couples who were suing a fertility clinic over the accidental destruction of their embryos. But its wording — paired with a fiery opinion from the chief justice encouraging lawmakers to push its scope further — has left many wondering about the possible wider implications for people seeking I.V.F. treatment.

At least three major fertility clinics in Alabama have halted I.V.F. treatments this week as doctors and lawyers assess the possible consequences of the ruling. On Friday, a major embryo shipping company said that it also was “pausing” its business in Alabama.

In interviews this week, people across the state expressed a fear that the ruling would hinder their journeys to parenthood through I.V.F., a process that is already considered emotionally and physically painful.

The ruling also raised perplexing questions: What rights will people have over their embryos? And could disposing of unused embryos lead to criminal charges?
