How Much Do You Know About Your Womb Lining?

You might not know much about the endometrial cells that line your uterus, but these are some of the hardest working cells in your body. Every month when you are menstruating, the endometrium thickness and then is shed during your period. The changes that happen are dramatic enough to be seen with ultrasound during an endometrial lining scan and they have a significant impact on your fertility.

Womb Lining

The Endometrial Lining

The endometrium is a special type of tissue that lines your womb:

  • The endometrium has two layers: the permanent basal layer and the functional layer that is shed during menstruation. Both layers can be seen on an endometrial lining scan.
  • The endometrium prevents the walls of the uterus from sticking together and creates a welcoming environment for an embryo when you are ovulating.
  • The endometrial cells react to the hormones oestrogen and progesterone, which cause it to grow thicker during the first half of the menstrual cycle and then to remain thick until the hormone levels drop and your period begins.
  • If you become pregnant, the embryo will implant itself into the endometrium. The endometrium will remain thick and develop a rich blood supply and form connections with the placenta to supply the baby with everything it needs.

Endometrial Thickness and Fertility

The endometrium needs to be in the right condition for you to get pregnant:

Health and the Womb Lining

Some of the most common gynaecological conditions relate to the endometrial lining:

  • Polyps are benign growths that are easiest to spot on a pelvic ultrasound or endometrial lining scan when the womb lining is at its thinnest towards the beginning of your menstrual cycle.
  • Endometriosis occurs when tissue that acts like your endometrial lining grows somewhere other than your uterus.
  • Endometrial hyperplasia is a benign condition that occurs when the womb lining is too thick. It can increase the risk of uterine cancer.
  • Endometrial cancer is the most common gynaecological cancer.
