Yes, you can have a tattoo during your treatment. However please bear in mind any procedure like this can increase the risk of infection. We do not advise you to have a tattoo after your embryo transfer. Once pregnant, although the risk is small, it is recommended that you wait to get a tattoo until after your baby is born. Little information is available about the safety of skin dyes used for tattooing during pregnancy. It is possible that the chemicals in the dye might affect the development of the baby during the first 12 weeks.
