Previous IVF failures

Despite its effectiveness, fertility treatment, particularly IVF, is a delicate and scientific procedure. For a successful IVF, both sperm and the eggs must be healthy and fertile for the embryo to be healthy enough to implant in the uterus properly. 

The problem arises when the eggs or the sperm are not of good quality leading to IVF failure.

There are a few IVF failure reasons that are prevalent.

• Quality and quantity of eggs and sperms

As women approach their late-30s, their eggs start to diminish in both quantity and quality.

Due to some lifestyle changes or health-related factors, sperm quality and quantity may be affected in men, leading to IVF failure.

• Unsuccessful Fertilisation

In certain circumstances, fertilisation just does not take place. This might be due to the egg’s or sperm’s quality.

• Failure in embryo implantation

An embryo failure might be caused by one of two factors.

1. The first factor is that the embryo’s environment in the uterus wasn’t sufficient to maintain it and endometrium or scar tissue might all be at blame 
2. The second factor of embryo failure would be detecting chromosomal defects in the embryo. It is recommended for women over 35 to get examined for chromosomal defective eggs

• Factors affecting your lifestyle

Smoking has a direct influence on the outcome of IVF procedures. Women who smoke more than two times a day might have a higher chance of miscarriage. The probability of a failed IVF cycle may arise if you are underweight or overweight.
