Cryoport, a major embryo shipping company, said on February 23 that it was “pausing” its business in Alabama as it evaluated the state’s Supreme Court decision that declared frozen embryos created through in vitro fertilization (IVF) to be children.

“Until the company has further clarity on the decision and what it means for Cryoport, clinics and intended parents, it is pausing all activity in Alabama until further notice,” read an email received by an Alabama fertility clinic and shared with The New York Times.

According to The New York Times, the email said that Cryoport would “not be able to assist” with a scheduled shipment, and instead would offer a refund.

Cryoport’s decision will make it more difficult for current IVF patients to move embryos out of state to continue treatments.

Embryo shipping is common in modern fertility treatment. When patients move, they need to switch clinics or move embryos they do not plan to use soon to a long-term storage facility.

Other companies also ship embryos, but it’s unclear whether they have changed their services in Alabama.
