Why don’t embryos stick? Key reasons you need to know
24 January 2025Why don’t embryos stick? Key reasons you need to know
Embryo implantation is a crucial step in the journey to parenthood. Despite advancements in fertility treatments like IVF, many couples face the heartache of failed implantation. Understanding why embryos don’t stick can provide insights and guide future treatments.
Here are five key reasons why this may happen:
1. Poor embryo quality
The quality of the embryo is the most critical factor in determining its ability to implant successfully. Even with the best embryos, the chances of successful implantation are only around 50%. This is why patients must understand that not every embryo, even a high-quality one, will stick.
Embryos of poor quality have reduced chances of implantation due to genetic abnormalities or developmental issues. During IVF, 70% of the success depends on the quality of the embryo. If implantation fails, evaluating the embryos—their quality and quantity—helps plan the next steps. If you want to learn more about poor-quality embryos, consider exploring additional resources or consulting your specialist.
2. Uterine problems
The uterus plays a vital role in supporting implantation. Problems within the uterus, such as fibroids, endometrial thickness issues, or infections, can prevent embryos from sticking. The size and location of fibroids or other lumps can directly impact implantation.
Endometrial health is equally important. The uterine lining must be thick and receptive to accept an embryo. If issues are identified, treatments like hysteroscopy, medications, or procedures to improve blood flow can enhance the uterine environment. Checking for infections or inflammation and treating them promptly is also crucial.
3. Overall health and Lifestyle factors
The mother’s overall health can significantly influence implantation success. Major illnesses, high fevers, or accidents between embryo transfer and pregnancy testing can negatively affect outcomes. Contrary to popular belief, strict bed rest post-transfer is unnecessary and may even reduce pregnancy chances by increasing stress levels and decreasing blood circulation. Instead, maintaining a balanced lifestyle is key to optimizing results.
4. Uterine receptivity
Uterine receptivity refers to the ability of the uterus to accept an embryo. Hormonal changes during IVF cycles can impact this receptivity. For instance, high hormone levels due to ovarian stimulation can make the uterus less accommodating, reducing implantation chances.
The decision to opt for fresh or frozen embryo transfer is critical and should be tailored to each patient’s response. While frozen embryo transfers may reduce certain pregnancy complications, they aren’t suitable for everyone. Natural cycle frozen transfers can offer better outcomes but require regular menstrual cycles. Customization of embryo transfer protocols based on the patient’s unique circumstances is essential for success.
5. Embryo transfer technique
The technique used during embryo transfer significantly influences implantation success. Minimizing uterine disturbance during the procedure is crucial. Any instrument entering the uterus can trigger contractions, reducing its receptivity.
An experienced doctor with a gentle and precise technique can make a significant difference. Studies show varying success rates for embryo transfers performed by different doctors, even within the same hospital. Choosing a skilled specialist is vital to maximize your chances of success.
Bonus tip: The role of ERA testing
Some doctors recommend the Endometrial Receptivity Array (ERA) test to determine the optimal time for embryo transfer. While this test can be useful for patients with multiple failed IVF attempts, recent studies suggest its benefits are limited. In many cases, ERA testing may not significantly improve pregnancy outcomes and can add unnecessary cost and delay. It’s best to discuss this option with your doctor to determine if it’s right for you.
Understanding these factors can help you navigate the complexities of IVF and improve your chances of success. Remember, every patient is unique, and personalized treatment plans are the cornerstone of effective fertility care.

FAQs
Adopting a balanced diet, regular moderate exercise, stress management, and avoiding alcohol, smoking, and caffeine can enhance implantation potential.
Yes, high levels of stress can influence hormonal balance and uterine receptivity, potentially reducing implantation chances.
Transferring multiple embryos can increase the chances of implantation but also raises the risk of multiple pregnancies. Your doctor will recommend the optimal number based on your case.
Yes, medications such as progesterone and estrogen may be prescribed to support the uterine lining and enhance implantation potential.
Acupuncture may improve blood flow to the uterus and reduce stress, potentially enhancing implantation rates. However, its effectiveness varies and should be discussed with a specialist.
Implantation typically occurs within 6-10 days after the embryo transfer, but this varies based on individual circumstances.
Endometriosis can affect uterine receptivity and embryo quality. Treating endometriosis before IVF may improve implantation chances. However any surgical intervention on ovary has the potential to reduce the number of eggs and embryos. It is better to understand ovarian reserve before planning endometriosis surgery.
Yes, autoimmune conditions like antiphospholipid syndrome or elevated natural killer (NK) cells can interfere with implantation. Treatments like immunotherapy may help in such cases.
