Women undergoing fertility treatment have been forced to make difficult decisions after a medical oversight body called for postponing procedures during the coronavirus pandemic as they race against time to get pregnant.

The Japan Society for Reproductive Medicine released a statement in April urging member doctors to ask patients to reconsider in light of how difficult a coronavirus infection will make their treatments and the possibility of mother-to-child transmission.

"I was about to progress to the next step, but it was suddenly halted," said a 33-year-old Tokyo woman who started receiving treatments three years ago.
