When do most IVFs fail?
IVF success rates under 35 are generally higher than for older women. However, even women in their early 30s can experience failed IVF cycles.
Here are some factors that can contribute to IVF failure:
Age: As women age, their egg quality declines, reducing the chances of successful fertilization and implantation.
Egg quality: Poor egg quality can cause IVF failure.
Uterine health: Problems with the uterus, such as uterine fibroids or polyps, can interfere with implantation.
Embryo quality: Embryos with genetic abnormalities or other issues may not develop into healthy pregnancies.
Lifestyle factors such as smoking, excessive alcohol consumption, and obesity can reduce IVF success rates.
Medical conditions: Certain medical conditions, such as endometriosis or polycystic ovary syndrome (PCOS), can affect fertility.
Number of IVF cycles: The more IVF cycles a woman undergoes, the lower the success rate for each cycle.
It's important to note that IVF failure is not always due to a single factor. Often, it's a combination of factors that contribute to the outcome.
