The most popular and effective fertility treatment for the majority of infertile couples is in vitro fertilization or IVF. Anyone considering IVF is making a significant life decision that should take organizational, financial, and emotional factors into account. Therefore, it is crucial to be aware of what to anticipate.
In vitro fertilization (IVF) has been a miracle for many women suffering from infertility. Most of us are aware that IVF is not a singular event, but a series of steps or a course of treatment. But if your first IVF cycle is unsuccessful, how many IVF cycles should you try before moving on to another option to start your family?
How many IVF cycles are required to get pregnant? In other words, what can you predict before you reach your goal? This article contains all the answers to your questions.
What is the cycle of IVF?
There are various stages in IVF. Even though they always follow the same pattern, it is important to keep in mind that the cycle is not always guaranteed to be completed. It’s possible that the initial round of ovarian stimulation is not having the desired effect on your ovaries.
It might be required in this situation to stop the cycle and begin a new cycle at the appropriate moment. Here are the procedures:
- Ovarian stimulation increases the number of oocytes produced by your ovaries.
- Egg collection after the oocytes reach sufficient number and maturity.
- Fertilization in the laboratory for pregnancy to occur.
- Culture and observation of the resulting embryos as they grow in the laboratory.
- Transfer of a selected embryo to your womb, hopefully, followed by implantation and pregnancy.
The whole process from start to finish takes about three weeks, followed by a two-week wait after the transfer to test if you are pregnant. (1)
How many IVF cycles should you try before giving up?
According to the study’s findings, 65.3% of patients who undergo six or more IVF rounds will be successful. Women under the age of 40 were most affected by these findings.
In the past, after three to four unsuccessful IVF rounds, the majority of specialists would advise women against continuing therapy using their own eggs. Women who produce no eggs or only two or fewer eggs per cycle find it especially disheartening.
- Dr. Debbie Lawlor, a senior researcher, said:
“These findings support the efficacy of extending the number of IVF cycles beyond three or four. As the number of treatment cycles increased, the cumulative [success] rate across cycles increased up to the ninth. Don’t give a load of importance to any one cycle.”
- The other principal investigator, Dr. Scott Nelson further clarified:
“For most couples – and certainly those where the woman is younger than 40 and those of any age using donor eggs – two-thirds will achieve a live birth after five or six treatment cycles. This will take, on average, two years and is similar to rates that couples conceiving naturally take in one year.” (2)
What factors influence the success of IVF?
The results of IVF involve more than simply numbers. In general, it is true that as the number of IVF rounds rises, so do the success rates. But there are also other elements that are present.
These factors include a patient’s fertility, general medical history, BMI, and the reason(s) for their specific patient’s infertility. But the most crucial element for a woman using her own eggs is age. The age of the receiver is far less important when using egg donation for IVF. (3)
