A transsexual activist will serve as a part-time lecturer at the medical school of Mie University, a public school, in November to educate students on sexual identity disorder.

"I'm looking forward to sharing with the students my experience of undergoing a sex-change operation and the various problems that transsexuals face, such as altering gender in our family registers," Masae Torai said.

The 38-year-old freelance writer from Tokyo, who switched from female to male in the United States in the late 1980s, has given lectures at some 50 universities and colleges all over Japan, but the new post "will be my first experience as a formal lecturer," he said.
