Why does IVF fail?

The sole aim of IVF procedure is to conceive, get pregnant and have a baby. But if the IVF procedure fails, it is not considered to be effective.  There are certainly some factors like obesity and infertility that lead to the ineffectiveness of IVF. 

Having obesity causes many other health conditions and it may also lead to birth defects and premature delivery.  Obesity is also responsible for hormonal changes and there is a probability for low amounts of estrogen and progestin hormones that play a major role in pregnancy.  Further, it is also important to check BMI to get the IVF treatment.

IVF specialists confirm that with healthy weight, it is much easier to produce more healthy eggs as compared to those who are facing the issue of obesity. This is due to the fact that IVF treatment works with eggs and after collecting the eggs, IVF specialists combine them with the sperm in the lab. If healthy eggs are not produced, it will not result in healthy embryos. Without healthy embryos, successful pregnancy cannot be achieved. 

Ensure healthy weight

As obesity and pregnancy are intertwined in IVF treatment, working on healthy weight is much encouraged. Take up some of the best activities like joining a gym,  choose a healthy and balanced diet and take at least eight hours sleep. Physical activities are often considered to be ideal for IVF to be successful as it helps women to maintain healthy weight and maximize the chance of conception. Walking for 30 minutes or choosing jogging is much recommended for best results.

The Procedure of IVF

Having a better understanding of everything that works in the IVF cycle, effective measures of healthcare, diet, exercise can be taken under the care of IVF specialists.

When hormone injections are administered, one egg is released from an ovary each month. IVF requires more eggs to be retrieved from the body which is why follicle-stimulating hormones are injected, to enable the release of multiple eggs that can be released at once and then retrieved. 

Eggs are retrieved through a minor surgical procedure with the help of ultrasound and guidance of a hollow needle.  There’s also medication to prevent any discomfort to the patient.

The next step is combining the eggs with male sperm followed by the process of insemination where the sperm and eggs are mixed together and stored in a laboratory for fertilization. 

In some cases, the probability is low for fertilization and at that Intracytoplasmic sperm injection (ICSI) is used. With this procedure, a single sperm is injected directly into the egg in order to achieve fertilization.

With the process of monitoring fertilization and cell division is achieved and once this occurs, fertilized eggs are called embryos.  Further, embryos are transferred into the woman’s uterus within three to five days following egg retrieval and fertilization.
