Announcement of the Launch of Zonazyme, a Reagent for Zona Pellucida Removal

November 27th, 2025

We are pleased to announce the launch of Zonazyme, a reagent specifically designed for the removal of the zona pellucida surrounding oocytes.

By removing the zona pellucida, this reagent may increase the likelihood that embryos which previously showed limited developmental potential can progress to the blastocyst stage, a developmental stage prepared for implantation. This approach is suitable for patients who have experienced poor embryo development in previous treatment cycles and may contribute to improved pregnancy outcomes.

We will continue to promote the development of products that contribute to enhancing reproductive medicine.

We will continue to promote the development of products that contribute to the advancement of reproductive medicine.
