The journey of conception and pregnancy through IVF (In-vitro Fertilization) is an emotionally challenging one. You are uncertain, anxious, and emotional all at the same time. Among the critical factors influencing IVF success is endometrial thickness, which should be optimal for successful embryo implantation. Continue reading to learn everything you need to know about it.
The innermost uterine lining is the endometrium, and its thickness varies throughout the menstrual cycle. The body prepares the uterine lining, or the endometrium, every month for potential embryo implantation and nutrition. If a woman becomes pregnant, the endometrium grows to support fetal development. If conception does not happen, the uterine lining is shed during periods.
The uterine lining's thickness changes with your menstrual cycle due to hormonal fluctuations. It is typically thinnest at about 2 to 4 mm during menstruation. After menstruation, it begins to thicken, reaching 5 to 7 mm pre-ovulation and 7 to 11 mm during ovulation. After ovulation, during the secretory phase, the endometrium can reach up to 12-14 mm in thickness.
During IVF treatment, your healthcare provider will monitor the uterine lining thickness to create the most favourable environment for implantation. The endometrium lining thickness must be optimal for the embryo to be implanted successfully during the IVF embryo transfer process. Typically, this thickness should be about 7 to 14 mm, but for average Indian women, it is between 6 and 9 mm. An endometrium that is under 7 mm may not allow the embryo to be properly implanted, which affects the chances of a successful IVF pregnancy.
Optimal endometrial thickness for IVF is crucial for successful embryo implantation. If the lining is less than 6 mm, there is a reduced chance of the embryo implanting into the uterus. However, it is not impossible, but it is a lot more challenging. On the contrary, if the thickness is more than 14 mm, embryo receptivity problems may occur. So, optimal thickness matters for the IVF success rate. The optimal range is 7 to 14 mm as it creates the best environment for embryo implantation. If the range is outside of this, there is nothing to worry about, as there are options to increase the thickness.
An ultrasound is performed to measure the endometrial thickness during IVF. If the uterus is abnormally positioned or there is a medical condition, an MRI is recommended. An optimal endometrial thickness is associated with better clinical pregnancy rates, a decline in pregnancy loss rates, and an increase in birth rates.
Low endometrial thickness symptoms include light or irregular periods during the natural menstrual cycle. However, there may not be any signs of thin endometrium. During IVF, even if you have a low thickness, it is treated so that it comes up to optimal thickness. A fertility expert will check the endometrial thickness before the embryo transfer process. This increases the chances of successful embryo implantation and reduces the risk of miscarriage in the later stages of pregnancy.
The endometrial thickness typically reduces with age. Studies suggest that endometrium thickness is generally greater in women under 25 and thinner in women over 40.
Estradiol is the primary estrogen hormone in women of reproductive age. It affects women's ability to become pregnant. If this hormone is below optimal levels during IVF, it can be the main reason for the lower endometrial thickness.
The cause of fertility issues or aetiology can affect the endometrial thickness while undergoing IVF treatment. For instance, if estrogen deficiency is the reason for fertility issues in women, it affects the endometrial thickness and the chances of becoming pregnant. Additionally, research suggests that the gonadotropin type and the induction of ovulation performed in IVF affect endometrial thickness.
Conditions like PCOS (polycystic ovary syndrome) may cause hormonal fluctuations affecting uterine thickness levels.
Asherman's syndrome and other health issues may lead to uterine scarring, making the endometrial lining thinner.
Procedures like D&C (curettage) and dilation may damage the uterine lining, making it thinner.
Follow a balanced and healthy diet to improve the endometrium thickness. Include:
Adopt a healthy lifestyle to create a positive thin endometrial lining IVF Impact.
Medical interventions may be needed in a few cases.
Consult a specialist for guided and personalised treatment based on your medical history and conditions.
Vitamin E and D supplements may prove helpful for endometrial growth. Consult a doctor before taking supplements.
Ideally, an optimal endometrial thickness is about 7-14 mm, with 8-10 mm considered particularly favourable for increasing the odds of pregnancy. Endometrium thickness is a primary factor in IVF success and affects the chances of miscarriage and childbirth. If your healthcare provider finds that it is less than 8 mm, a treatment plan is devised to address it.
The endometrial thickness needs to be optimal for proper embryo implantation during IVF. A holistic approach includes a balanced diet, an appropriate lifestyle, supplements and medical treatments. However, an assessment by a professional is the key to getting the best outcome during the IVF embryo transfer process.
If the endometrial thickness is below 7 mm, it is linked with embryo implantation failure and low pregnancy rates.
Poor uterine blood flow, hormonal imbalances, uterine scarring and medical conditions are some causes of a thin endometrial lining.
A balanced diet, lifestyle changes, supplements and medical treatment for health conditions are some ways to boost endometrial lining and IVF outcomes.
