IVF Failure Reasons You Need to Know

IVF Failure Reasons You Need to Know

IVF is recognized as a safe technology. However, not every couple is lucky enough to pass through the obstacles and conceive a child by IVF. There have been numerous cases where IVF fails for infertile couples. In this blog, we will cover 5 reasons for the failure of IVF. Read on to know- 

  1. Egg Abnormalities

An egg abnormality takes place due to chromosomal abnormalities in the eggs of a woman. A chromosomal abnormality can either be structural or numerical. While a numerical abnormality happens when there is a missing chromosome or an extra chromosome, a structural abnormality takes place when there is a structural problem with the chromosome. Numerous recent investigations have revealed that between 25% and 40% of all oocytes (immature eggs) have defective chromosomes.

  1. Abnormal Sperm

Another common reason for IVF failure is abnormal sperm. This type of sperm either has head or tail defects. This means that the head of the sperm is large or it has a crooked or double tail which restricts the sperm from reaching and penetrating the egg. However, this isn't uncommon. In a semen sample, typically, 4–10% of the sperm are considered normal. Lifestyle choices, illnesses, or genetic conditions can contribute to abnormal sperm production.


  1. Embryo Selection Methods

One of the many factors that contribute to IVF failure is embryo selection methods. After selection by the embryologist at the best IVF centre in Delhi NCR, the embryos are then put into the woman's uterus. Unfortunately, despite all of our technical advances, we are still unable to distinguish between embryos with normal chromosomes and those with abnormal chromosomes. There is always a risk since these embryos' viability can occasionally be affected by biological variance.

  1. IVF Lab factors

The environment in the IVF lab is strictly regulated. Every aspect of the lab is constantly monitored and controlled. The embryo can be killed by even the smallest alterations made within the lab with many factors, including oxygen, light, carbon dioxide, temperature, or even the pH factor. As a result, the climate inside a lab is crucial and, if changed, can contribute to the failure of IVF.
