Reports indicate that scientists in China have used CRISPR-mediated genome editing during in vitro fertilization to modify the genetic material of two embryos that were subsequently implanted into a patient, leading to the birth of two babies. As ISSCR and a number of other organizations have previously stated, the use of nuclear genome editing technologies, such as CRISPR, during fertility treatment is premature and should not be attempted at this time.

In a letter to the U.S. Food and Drug Administration (FDA), the ISSCR commented on proposed industry guidance for "Civil Money Penalties Relating to the ClinicalTrials.gov Data Bank."
