When is the time for endometrial examination?

Endometrial examination is a routine gynecological examination, but the time for endometrial examination is regulated. Only by doing endometrial examination within the prescribed time can you get reliable results. So when is the time to do an endometrial examination? Next, this article will introduce you to the time for endometrial examination. Friends who want to know when the time for endometrial examination is, come and have a look!

The endometrium is the layer that makes up the lining of the mammalian uterus. It responds to both estrogen and progesterone, and therefore can change significantly with the sexual cycle (estrus cycle, menstrual cycle). The endometrium is divided into three layers: the compact layer, the spongy layer, and the basal layer. The dense layer and spongy layer of the 2/3 endometrial surface are collectively called the functional layer, which are shed periodically under the influence of ovarian sex hormones. The basal layer is the 1/3 of the endometrium close to the myometrium. It is not affected by ovarian hormones and does not undergo cyclical changes.

When is the time for endometrial examination? Since the endometrium changes cyclically, in order to examine the endometrium, samples must be taken within the specified time to accurately reflect whether ovulation or other abnormal phenomena occur. The most suitable time is 2-3 days before menstruation or within 12-24 hours of menstruation. If the endometrium taken out is found to be secretory endometrium by pathological examination, it means ovulation has occurred. If menstruation has occurred for more than one day, most of the old endometrium has fallen off and the new endometrium has begun to grow. At this time, taking the endometrium for examination often does not give correct results. Because the ovaries do not ovulate every month, sometimes they may ovulate after a month.

Therefore, even if no ovulation is found during an endometrial sampling, it does not necessarily mean that the ovaries are not ovulating. In addition to determining whether ovulation has occurred, endometrial examination can also diagnose other diseases. Infertile women should check whether the endometrium has tuberculosis lesions. Sometimes patients with endometrial tuberculosis do not have any symptoms and can only be diagnosed by taking an endometrial sample.

In order to improve the diagnosis rate, it is best to scrape the endometrium 2-3 days before menstruation. At this time, the endometrium is thick, and it is easy to obtain more endometrial tissue for examination by the pathologist. In addition, by taking the endometrium, we can also understand whether the patient has lesions such as fibroids or polyps in the uterine cavity.

The above is an introduction to when to perform endometrial examination. From the above introduction, we can know that the time for endometrial examination is generally 2-3 days before menstruation or on the first day of menstruation. Only endometrial examination done during this period is more accurate. Therefore, for friends who want to do endometrial examination, be sure to choose the right time!
