Yin May, the first Burmese obstetrician and gynecologist, founded and ran the country’s main maternity hospital during the Japanese occupation of Burma. She was the first person to perform the Caesarian section in Burma and is known for her research on amoebic vaginitis, also called May’s disease.
While pregnant and separated from her family, Yin May founded the country’s primary maternity hospital during the Japanese occupation (1942–1945), working long hours with staff who had no OB/GYN experience. Burma had lost its main maternity hospital, Lady Dufferin Maternity Hospital, on 25 December 1941 due to Japanese aerial bombing and then the Japanese army commandeered Rangoon General Hospital for their use only. She later co-founded wartime medical and nursing schools (1943–1945). After World Wai II, she ran Lady Dufferin Maternity Hospital from 1946 to 1959, and was head of the Department of Obstetrics and Gynecology of the Faculty of Medicine of Rangoon University from 1947 to 1959. Under her leadership, Dufferin became a maternity hospital recognized by the Royal College of Obstetricians and Gynaecologists in 1957.
