In vitro fertilization in Australia is becoming more and more recognized as an effective and valid option for getting pregnant. The IVF success rates sensationalized by TV and movie celebrities encourage regular couples to try their luck using this type of reproduction process. If you are one of these aspiring parents, have you considered the factors that could affect the IVF success rates? Here are some of the elements that may have an impact on your IVF journey to parenthood.

Common factors that affect IVF success rates



It is the most talked about factor in pregnancy. In general, a woman’s age affects the maturity and number of her egg cells. As women age, their egg cells reduce in quantity and quality, making it difficult for the reproduction process to happen. This fact is also true with in vitro fertilization. If fewer eggs are harvested during the IVF, there is a lesser chance that a healthy egg will be fertilized. In fact, IVF success rates for women below age 35 are 40%, while women over 40 years of age have only 4% chances of getting pregnant.


Previous pregnancy

IVF specialists and fertility experts both observed that if you have been successful in getting pregnant before and want to undergo IVF with the same partner, then the probability of getting pregnant is higher. However, if you have a history of miscarriage, it would also affect the IVF success rates.



Infertility problems

The reason for the difficulty in getting pregnant can also affect your IVF success rates. For women, if your reproductive issues involve your uterine condition and your ovulation, this may decrease your IVF success rates. Reproductive illnesses such as uterine fibroids, myoma, cancer, and ovarian dysfunction, even hormonal imbalances can significantly affect a woman’s capacity to become pregnant using IVF.



Smoking and obesity can affect a couple’s chances of having higher IVF success rates. The chemicals found in cigarettes and other smoking products substantially affect the reproductive system of both men and women. Meanwhile, obesity was found to have a strong effect on the body’s reaction to medications given during the IVF procedure. IVF specialists encourage changing these lifestyle factors to attain higher IVF success rates.


Choice of fertility clinic and specialist

IVF success rates also rely on the expertise of the specialist and the facility where it is performed. No matter how healthy the eggs and sperms are, if the specialist lacks the knowledge on how to perform such delicate procedure, and if the facility lacks the technology to safely house the cells needed for reproduction, getting higher IVF success rates is impossible.  Research about a clinic and the IVF specialist’s experience in handling situations like yours. Ask them to provide information about their experience, pregnancy ratio per embryo transfer, pregnancy rate based on age group, and live birth rate, among others. Your fertility expert’s knowledge and skills partnered with their state-of-the-art facility is an integral part of what affects your IVF success rates.



There will always be a cloud of doubt hanging above your head during your IVF pregnancy journey. We must accept that there are many uncertainties involved during this fertility process. We just have to know the things we can control and improve these factors so we can reach our expected chances of greater IVF success rates.
