The lining of the uterus plays a very important role in the conception process and the ability of each woman to become pregnant. Therefore, thick uterine lining or thin uterine lining both have certain effects on pregnancy. The lining of the uterus, also known as the endometrium, is a layer of tissue that covers the entire inner surface of the uterus, plays an important role in fertility and pregnancy, under the influence of hormones. In the female reproductive system, the uterine lining thickens depending on the specific time of the month. Thickening of the uterine lining is a sign of preparation for a fertilized egg (if any) to implant.
If there is no fertilization during the menstrual cycle, the endometrium will shed on its own and cause vaginal bleeding, also known as menstruation. After this process, the cells in the basal layer will start to grow again to form a new lining during the next menstrual cycle.
In case the fertilized egg implants in the uterus, the hormones produced during pregnancy will continue to work to make the uterine lining thicker and change its structure to suit the development of the embryo. and placenta. Therefore, if the lining of the uterus is too thick or becomes abnormal, conception and the ability to become pregnant will also be affected.
The effect of the lining of the uterus on fertility will occur when: The lining of the uterus is too thin (causes menstrual problems, women with the lining of the uterus thinner than 6mm after the fertilized egg will causes difficulty in attaching to the uterine wall of the embryo), too thick uterine lining will also have a certain effect because this phenomenon causes hormonal imbalance and leads to menorrhagia, secondary amenorrhea lengthen.
How thick is the uterine lining to get pregnant is a question many people are interested in. Usually, the thickness of the uterine lining between 8 and 10 mm is considered the most ideal size for conception in women.
