Bruce Jenner has been a constant topic among entertainment press with the fascination of his supposed sex chnge. Rumors intensified when Jenner was caught sporting a ponytail dyed in ombre-ready color, which he refused to cut even after stephdaughter, Kim Kardashian begged him to, stating that it will ruin her wedding photos.

According to Celeb Dirty Laundry,Jenner's estrogen treatments are the likely cause of his most recent physical changes. The report added that, "hormone therapy is just one more step towards gender reassignment," and that Jenner's estrogen treatment "seems to solidify the idea that this is precisely what Bruce is in the process of doing." And thanks to these treatments, Jenner looks as if he's growing man boobs - and looking more feminine.

Besides the seeming "gradual" transformation, TMZ reported that earlier this year, Jenner has undergone a plastic surgery procedure called Laryngeal Shave to smoothen out his Adam's Apple.

A number of reports have also alleged that Jenner is obsessed with wearing Spanx-which his stepdaughter, Kim Kardashian has openly admitted to loving because it helps her achieve a more flattering figure, according to The Examiner.

The 64-year old, 1976 Decathlon gold medal Olympian has long admitted that his obsession with plastic surgery is due to wanting to keep looking young. Before the many plastic surgery procedures, Jenner is known for his rugged, handsome look.

In an episode of  "Keeping Up With the Kardashians," he said that he was tired of Kris, his wife, telling him everything that he needs to do for the past 20 years: "I'm in the last quarter of life...I want to be free to do what I want and live life the way I want."

Some medical observers believe that Jenner is suffering from a body dysmorphic disorder, an obsessive preoccupation with minor or nonexistent flaws in the body. The "man boobs" on the other hand could be explained by the decrease level of testosterone which is not an uncommon phenomenon among older men, especially for men who have lost a lot of weight.
