Transgender ice hockey athlete Jamie McCulloch competed twice on Monday in the Gay Games -- once as part of the Boston men's hockey team, and a second time as part of the women's team.

McCulloch is one of a handful of transgender athletes at the Sydney-hosted games who have found themselves in the middle of consternation about whom they should be competing against, reports The Australian.

McCulloch dismissed female athletes' concerns that transgender athletes -- particularly male-to-female competitors, such as McCulloch -- have an unfair advantage because of their strength.

"We have to go through extensive hormone replacement therapy and anti-testosterone treatment so that by the time we have had surgery our muscle mass has reduced by at least 50 percent," she said.

At the Amsterdam Gay Games four years ago, transgender competitors were required to provide documentary evidence of "complete gender transition," but Sydney organizers dropped that requirement.

McCulloch had gender reassignment surgery five years ago. She believes that men living as women who have not had surgery should not be allowed to compete against female athletes.

"But for post-operative transgenders like me, it's not an issue -- look, I was going to a gynecologist who didn't even know," she said.
