Chances of getting pregnant in IVF
What are the chances of getting pregnant in IVF?
The chances of getting pregnant with IVF (in vitro fertilization) can vary based on several factors, including:
- Age: Younger women typically have higher success rates. For women under 35, the success rate per IVF cycle can be around 40-50%, while for women over 40, it tends to be lower.
- Cause of infertility: The underlying reason for infertility plays a significant role. For example, women with unexplained infertility or male infertility issues may have higher success rates than those with issues such as diminished ovarian reserve or poor egg quality.
- Ovarian reserve: The number and quality of eggs a woman has left (measured through tests like AMH levels or antral follicle count) will impact the chances of success.
- Embryo quality: The quality of embryos transferred also matters. Better-quality embryos are more likely to result in a successful pregnancy.
- Clinic expertise: Success rates vary between fertility clinics based on experience, equipment, and treatment protocols.
- Lifestyle factors: Smoking, being overweight or underweight, and other health conditions like diabetes or thyroid issues can affect IVF success rates.
On average, success rates in the U.S. for a fresh IVF cycle are around:
- For women under 35: 40-50%
- For women 35-37: 30-40%
- For women 38-40: 20-30%
- For women over 40: 10-20%
However, these are general estimates, and individual circumstances can differ. It’s best to consult with a fertility specialist to get personalized information based on your specific situation.
🗒️ Answer
The chances of pregnancy through IVF depend on several factors such as age, health, and the number of cycles attempted:
- Women under 35: The chance of pregnancy per IVF cycle is about 32-55% [1], [5].
- Women aged 35-37: Success rates drop to approximately 25-32% [5].
- Women aged 38-39: The chances of pregnancy decrease further to around 19% [5].
- Women over 40: Success rates are much lower, around 5-11%, depending on age [5].
Additionally, success rates improve with multiple IVF cycles. After one cycle, the chance of pregnancy is about 40%, rising to 60% after two cycles and 70-80% after three cycles [4].
