that will be why there are no berries. The flower contains an ovary with the 'egg' that when fertilizer will develop into a berry. It has having a year off then.

No they cant change sex. It could be that when its flowers opened they were just not able to be pollinated. Did it flower as they can take a year off especially if they berried heavily the year before.
