AboutAbout the lab
Studying the fetus from a broad range of perspectives, from fetal diagnosis to child-rearing support
The Maternal-Fetal Medicine Lab studies the fetus from a broad range of perspectives, from fetal diagnosis, fetal therapy, and grief care for fetal death to creating better childbirth and better child-rearing environments.
The Fetal Diagnosis and Treatment Center, opened by Osaka University Hospital in 2015, is dedicated every day to pregnant women, their families, and the babies in the womb.
For grief care, the lab aims to build a system that can be provided through collaboration among many professions, including obstetrics and gynecology, psychiatry, midwives, clinical psychologists, and medical anthropologists.
The lab's website is presented on a joint website together with the Perioperative Management Lab and others.
Key terms
- Grief care
- Care that stays close to and supports the sorrow of pregnant and postpartum women and families who chose second-trimester delivery.
- Uterine electromyography sensor
- A sheet-type wireless sensor that detects the electrical changes (electromyographic potential) produced by the uterine muscle.
- Machine learning
- A method of having computers learn patterns from data. Here, it is used to judge from changes in electromyographic potential whether contractions are labor.
- Ethnography
- A record compiled from participant observation and interviews in the field.

The lab studies the fetus from a broad range of perspectives, from fetal diagnosis, fetal therapy, and grief care for fetal death to creating better childbirth and better child-rearing environments. It also works on developing sensor-based devices and on research from medical, cultural, and social perspectives.
*Illustrative imageFetal Diagnosis and Fetal Therapy
Advances in ultrasound and genetic analysis have made it possible to detect fetal diseases earlier. At the same time, encounters with fetuses whose conditions cannot be treated have increased, and the lab aims to build an interprofessional grief care system for families and healthcare providers who have chosen second-trimester delivery.
*Illustrative imageStudy of Watching Over the First 1,000 Days of Life
The study aims to provide individualized child-rearing support and ease mothers' difficulties in raising children. Using smartphones, wearable sensors, and a newly developed child-rearing monitoring robot, it measures the living conditions of pregnant and postpartum women and children over time. In collaboration with researchers and companies inside and outside the university, the lab builds a system that delivers early signs of changes in health and advice when they are in trouble.
*Illustrative imageDevelopment of a Fetal Monitoring System
Changes in electromyographic potential measured with a sheet-type wireless uterine electromyography sensor are analyzed with machine learning to judge whether contractions are true labor leading to delivery or false labor. In joint research with other institutions, the lab works on developing a device that can identify preterm birth and placental abruption early, and on establishing evaluation methods.
*Illustrative imageMultifaceted Investigation of the Current State of Childbirth
The lab studies the current state of pregnancy, childbirth, and the postpartum period through participant observation, including interviews with pregnant and postpartum women, families, and healthcare professionals, and compiles the findings as ethnography. It also clarifies the characteristics of childbirth through comparison with history and other cultures, in joint research with Prof. Yasui's group at the International Research Center for Japanese Studies.
