Success Is Not Guaranteed At Each Cycle
In vitro fertilization (IVF) is a fantastic treatment for couples struggling with fertility problems. The procedure also helps LGBTQ+ couples or women with frozen eggs who are interested in family planning. While IVF has helped hundreds of thousands of couples have children, the technique is not guaranteed. On average, an IVF cycle has a 21% – 50% success rate, depending on factors like age. Most IVF patients require multiple IVF cycles before a successful pregnancy. After an unsuccessful IVF cycle, patients have the option of starting another round of IVF or delaying the process. Choosing the right option may influence the success rate.
What causes a failed IVF cycle?
Although IVF has favorable success rates, there are reasons why an average IVF fails. Egg, sperm, or embryo quality can lead to poor fertilization or implantation. Some women may have problems with the uterine lining, such as endometrial hyperplasia, fibroids, or polyps. The embryo intended for implantation may have a chromosomal abnormality that can lead to miscarriages or low success rates. Even with optimal conditions, there are unexplained reasons why an IVF cycle can fail. However, addressing these potential obstacles can improve IVF outcomes.
Should you wait?
Sometimes, IVF patients may choose to rest or delay starting another IVF cycle. Postponing the next cycle gives the body a chance to recover from the side effects of hormone medication and the physical demands of IVF. The IVF process is also emotionally demanding, so delaying the next cycle can provide some much-needed rest. Waiting also presents some advantages from a health standpoint. If the medical team identifies an underlying issue impacting implantation, delaying the cycle provides enough time for treatment. The length of time and reasons for waiting can be discussed with all parties involved before deciding.
Advantages of pushing through
Some IVF patients will attempt another cycle after doctor approval. IVF can be emotionally taxing. Starting another cycle keeps up the momentum and focus on pregnancy. If new eggs are required, delaying IVF cycles increases the chance of harvesting lower-quality eggs. Some women experience increased fertility in the months following a failed cycle. Attempting another cycle capitalizes on this window. If the fertility team identifies a potential cause of the failed IVF cycle, the team can make immediate adjustments, potentially increasing outcomes. The team can continue to manage the process without restarting the vital parts of IVF, which can improve success rates.
Do what’s best for you
As is standard in most IVF clinics, the patient will need to wait for a complete menstrual cycle between each attempt. Starting immediately after this period is considered a back-to-back cycle. Waiting longer is a delayed cycle. Waiting can offer some benefits in terms of stress reduction and lifestyle changes. Some patients can also benefit from health adjustments, thereby increasing success rates. Waiting, in most cases, is a personal decision. Studies show that delays do not negatively impact pregnancy outcomes, but factors like age, health, and reasons for failed IVF cycles will play a role. When in doubt, speak with the fertility team for guidance.
