Cumbersome and explosive
Within the early days of IVF, embryos earmarked for storage have been slow-frozen. This method entails step by step decreasing the temperature of the embryos. However as a result of gradual freezing could cause dangerous ice crystals to type, clinics switched within the 2000s to a method referred to as vitrification, through which the embryos are positioned in skinny plastic tubes referred to as straws and lowered into tanks of liquid nitrogen. This quickly freezes the embryos and converts them right into a glass-like state.
The embryos can later be thawed by eradicating them from the tanks and quickly—inside two seconds—plunging them into heat “thaw media,” says Atkinson. Thawing slow-frozen embryos is extra difficult. And the precise thawing technique required varies, relying on how the embryos have been preserved and what they have been saved in. Among the units must be opened whereas they’re contained in the storage tank, which may contain utilizing forceps, diamond-bladed knives, and different instruments within the liquid nitrogen, says Atkinson.

Not too long ago, she was tasked with retrieving embryos that had been saved inside a glass vial. The vial was constituted of blown glass and had been heat-sealed with the embryo inside. Atkinson had to make use of her diamond-bladed knife to snap open the seal contained in the nitrogen tank. It was fiddly work, and when the machine snapped, a small shard of glass flew out and hit Atkinson’s face. “Hit me on the cheek, minimize my cheek, blood working down my face, and I’m like, Oh shit,” she says. Fortunately, she had her security goggles on. And the embryos survived, she provides.
Atkinson has a folder in her workplace with notes she’s collected on varied units over time. She flicks via it over a video name and factors to the notes she made concerning the glass vial. “Would possibly explode; put on face protect and eye safety,” she reads. A number of pages later, she factors to a different embryo-storage machine. “You need to thaw this one in your fingers,” she tells me. “I don’t prefer it.”
The record-breaking embryos had been slow-frozen and saved in a plastic vial, says Atkinson. Thawing them was a cumbersome course of. However all three embryos survived it.
The Pierces needed to journey from their dwelling in Ohio to the clinic in Tennessee 5 instances over a two-week interval. “It was like a five-hour drive,” says Lindsey. One of many three embryos stopped rising. The opposite two have been transferred to Lindsey’s uterus on November 14, she says. And one developed right into a fetus.
Now that the newborn has arrived, Archerd is eager to satisfy him. “The very first thing that I seen when Lindsey despatched me his photos is how a lot he seems like my daughter when she was a child,” she says. “I pulled out my child e-book and in contrast them aspect by aspect, and there’s no doubt that they’re siblings.”
She doesn’t but have plans to satisfy the newborn, however doing so can be “a dream come true,” she says. “I want that they didn’t dwell so far-off from me … He’s excellent!”
“We didn’t go into it pondering we’d break any data,” says Lindsey. “We simply wished to have a child.”
