The Japan Society for Transplantation is understood to be drafting guidelines on how to treat women who want to conceive and give birth while taking medication after transplant surgery — the first move of its kind worldwide.

The organization plans to release the guidelines as early as October, when it holds a general meeting. An English-language version is also underway.

Patients who receive donated organs must take an immunosuppressive drug to reduce the risk of rejection. Moreover, some also need to take antihypertensive drugs to counter the increased risk of high blood pressure.
