Embryo Glue??

Hello everyone! We go for our <a href="https://glowing.com/glow-fertility-program">ivf</a> orientation on Monday and we have to pay for the optional things up front. We have to pay 1250 for freezing and if we elect for the glue it’s an additional 200. I’m wondering if anyone has had success with it or without? Trying to decide if it’s a better bet or not. Thanks y’all
