A Japanese research team has developed artificial intelligence models that can help deliver personalized infertility treatments by predicting the number and quality of eggs that a woman has.

The AI models can accurately predict a patient’s ovarian function by using answers to simple questions — such as age and menstrual cycle — and a small sampling of blood, according to the group study led by University of Tokyo researcher Miyuki Harada.

The group collected data from 442 patients who were undergoing infertility treatment between June 2021 and January 2023 in Japan. Using their medical records and residual serum, the group created multiple AI prediction models.
