Aspiration biopsy of the endometrium has come to replace other more traumatic methods of examining the uterus. Today, a vacuum aspiration biopsy is used instead of a separate diagnostic curettage.

It is introduced into the uterine cavity, and at the time of its extraction a negative pressure occurs, as a result of which endometrial tissue is drawn into the cylinder. The whole procedure is absolutely painless.
Further, under laboratory conditions, the resulting tissue sample is examined by a histological method. Results are prepared within 7 days. After that the doctor can start treatment of the patient.
