If you have undergone failure in your first IVF cycle, then feeling disappointed is obvious. According to the IVF centre, even though IVF is one of the best fertility treatments, it might have some cases of failure. The success or failure depends on various factors such as the age of the mother and her ovarian reserve. It yields 40 per cent success for women under 35 but the possibility goes down for women above 40.
Causes of IVF Failure
As mentioned above, many factors influence the success of an IVF cycle. The three top most factors are the age of the female, the embryo quality, and poor ovarian response to the procedure. With age, women start producing fewer eggs and a decline in the quality of their eggs is also seen. The decline usually accelerates after the woman hits the age of 37.
Poor embryo quality also attributes to the failure of IVF. Embryos of poor quality fail to implant as they are too defective to grow properly.
The poor ovarian response is also a critical factor in deciding the success of IVF. The ovarian response is defined as the kind of response the ovaries give to the fertility medications. The production of multiple eggs due to medication is dependent on the ovarian response.
The next cycles of IVF
While there is no surety that the first IVF cycle will be successful, you can opt for a second or third cycle with more precaution to improve your chances of pregnancy. The reasons for the failure will be determined if your first cycle fails. The reproductive endocrinologist will look into the causes and work out if there are any problems with egg quality or quantity, development of the embryo, or in the transfer of the embryos to the uterus.
Usually, at various fertility centers, the highest success rates are achieved with two cycles.
In case the ovarian stimulation was not up to the mark, the doctor will recommend changing the drugs used in stimulation.
In case the embryo implantation step failed, then preimplantation genetic screening (PGS) screening is suggested. PGS is a process in which the biopsy of the embryo is carried out to determine the number of chromosomes which enables the selection of healthy embryos.
Finally, you may also need to alter your lifestyle if you want to have a successful IVF. Stopping smoking, abstaining from alcohol and refraining from drug abuse can improve your chances of success in IVF.
