ART， The Chinese meaning is "art", which is also an abbreviation for "assisted reproductive technology" in the field of reproductive medicine. Therefore, in vitro fertilization is also known as "ART baby" by doctors. This artistic name adds a touch of mystery to in vitro fertilization. So, what is the success rate of in vitro fertilization?
What is the success rate of in vitro fertilization?
The success rate of in vitro fertilization can reach an average of about 40%, which does not mean that only 40 out of 100 couples who undergo in vitro fertilization can succeed, but rather that there may be 40 chances of success after 100 surgeries.
Calculating the success rate of in vitro fertilization will yield different results using different methods. Most hospitals calculate the clinical pregnancy rate, but for patients, only the live birth rate is meaningful.
Generally, ultrasound examination is performed around 30 days after embryo transfer, and confirmation of the presence of a gestational sac through ultrasound examination indicates clinical pregnancy.
The live birth rate refers to the percentage of patients who are able to give birth to normal babies during each treatment cycle or embryo transfer.
The clinical pregnancy rate is usually higher than the live birth rate, as about 10% to 15% of patients may experience miscarriage after clinical pregnancy.
The Ministry of Health stipulates that in our assisted reproductive procedures, the pregnancy rate is evaluated based on clinical pregnancy rate. However, for patients, the success rate they can better understand and accept is the live birth rate.
The success rate and technical level of in vitro fertilization are closely related to the patient's condition. Young and previously pregnant patients have a higher success rate; Patients with advanced age and complex infertility factors, or those with comorbidities, have a low success rate. Therefore, when calculating the success rate, if difficult patients or patients with low success rates are removed, false impressions may appear. And the calculation of success rate should be based on the success rate obtained from a larger base or a longer period of case accumulation.
In summary, the success of IVF cycles cannot be achieved without three factors: 1. having available eggs; 2. Forming usable embryos; 3. The uterine environment is conducive to implantation. If you really want to undergo IVF surgery, I wish you all the best. Also, pay more attention to your health.
