This post above sums the effect precisely. Lupron-like drugs fool the body to stop makng T by flooding the system with T-creating hormone signals (leutinizing hormone), generating a shutdown of gonad production. After this process is complete and testosterone rises organically the body is "fooled" again until a new point of stability is reached and estrogen aromatization is reduced to the normal level for an adult male. This interim period where T rises but the body has not sufficiently or fully recognized the natural state is when estrogen is aromatized and causes mild feminine body reactions. Sometimes not so mild.
