Christian is a 22-year-old man with C-cup breasts. While the occurrence of "man boobs" is often met with derision, as they're thought to have been earned through such punishable offenses as obesity or an inherent femininity, they're actually due to a medical condition. Gynecomastia causes abnormal development of large mammary glands, creating big breasts. A combination of breast tissue and fat that no amount of exercise can help, as Christian knows. He had been working out six hours a week to try and reduce his breast size.
Featured on the TLC show Strange Sex, Christian eventually decided upon breast reduction surgery. (His before and after pictures, at left.) And apparently, it's not uncommon. In 2010 alone, there were 18,000 male breast reduction surgeries performed in the U.S.
