IVF Success Factors & Success Rates

Attributing Factors to IVF Success

IVF is an assisted reproductive technology. During this process, a woman is given drugs to stimulate the production of more than one egg during her cycle. Then a man’s sperm is fertilized outside of the woman’s body with her eggs. After that, the eggs are then implanted in her uterus. This process bypasses the Fallopian tubes. Those who are thinking about undergoing this process to become pregnant will have to take multiple factors into account before they begin. Factors that can influence a woman’s chances of getting pregnant include her age, any previous miscarriages, any previous full term, successful pregnancies and any previously successful attempts at IVF. Each factor will help determine her chances not only of getting pregnant, but her chances at having a full term, fully healthy baby.

IVF Success Factors & Success Rates

Age

Perhaps the most important possible issue when it comes success with this medical procedure is a woman’s age. Younger woman under thirty have much higher success rates than women thirty-five and older. When a woman is born, she has all the eggs she will ever need with her. As she ages, so do her eggs. A woman who is older will have older eggs and thus have a decreased success rate. However, this varies depending on the woman. Some woman have eggs that are younger than their biological age. Others have eggs that are older than their biological age. A simple blood test called the FSH or Follicle Stimulating Hormone test can help women find out how old her egg are and how likely they are to fertilize. If her hormones are above a certain level, her chances at success may not be as good.

Previous Pregnancies

A history of previous pregnancy can also help predict IVF success. Women who have been pregnant and given birth with their partner in the past are likely to have a successful IVF session. Their eggs have been mingled in the past to create a baby. This means that she and her partner’s body parts are compatible. Women who have never been pregnant before face reduced success rates. If a woman has a history of miscarriage with her partner’s eggs that can also indicate that she has a reduced risk of success with IVF.

Alcohol and Tobacco Use

In addition to age, another factor is the woman’s overall general health. Women who use tobacco or have a partner who also uses tobacco are less likely to get pregnant. Those who have smoked in the past but have chosen to stop also have impaired fertility in many instances but to a lesser degree. The same is true for those who choose to drink. Alcohol can impair fertility in many subtle ways so it is best to avoid it more than once a week when undergoing a round of IVF.

Obesity

Another factor that may lead to reduced success IVF rates is obesity. Those who maintain a healthy weight are likely to avoid issues like high blood pressure that may impede the flow of blood to the uterus and testes. Losing weight can help increase the possibility of a successful IVF cycle.

Increasing Success Rates

Those who plan to undergo an IVF cycle can do things to help increase their chances of success. Losing weight and exercise can help. Getting issues such as high blood pressure under control can also help. Older woman who do not have success initially can turn to donor eggs rather than their own eggs and vastly increase their chances for a successful round and live birth.
