Thanks for your query.
Disordered proliferative endometrium is not a major disease.
it will respond easily to hormonal
management ( generally cyclical progesterone
therapy given each month during particular days ).
Disordered endometrium generally indicates a problem in ovulation also, hence that might affect your fertility
once the condition is adequately treated with hormones, it might get cured totally.
consult your gynecologist for detailed evaluation and treatment.
All the best.
