Treatment cycle and times of IVF
IVF technology is an assisted reproductive technology that helps couples realize their reproductive dreams through in vitro fertilization and embryo transfer. The length of treatment cycle and frequency is determined by many factors, including the couple's age, reproductive health status and doctor's advice.
1. Basic treatment cycle
Generally speaking, the treatment cycle of IVF is about 4-6 weeks. Let's take a closer look at this process.
The first step is to take ovulation promoting drugs to promote ovarian development and increase the number of eggs. This stage usually lasts for 10-12 days. During this period, you need to go to the hospital several times for blood examination and ultrasonic monitoring to determine the development of eggs.
The second step is egg collection. After ovulation is triggered, the doctor will take out the mature eggs through colposcopy or vaginal ultrasound guided egg retrieval. This process usually requires allogenic glucocorticoids to help egg development. The operation usually lasts for 20-30 minutes, and local anesthesia or mild intravenous anesthesia is usually used.
The third step is in vitro fertilization. The eggs taken out will be fertilized in vitro with sperm in the laboratory to form a fertilized egg. This process is usually carried out within 24 hours after egg collection.
The fourth step is embryo culture. The fertilized eggs continue to be cultured in the laboratory, which usually takes 3-5 days to reach the best embryonic development stage. During this period, doctors will conduct embryo observation every day to determine that the best embryo can be transferred.
The fifth step is embryo transfer. Doctors will transfer the best embryos into the mother's uterus through hysteroscopy guided embryo transfer. This process is usually simple and does not require anesthesia.
2. Treatment times
The number of treatments varies from individual to individual. Some couples may successfully conceive in the first treatment cycle, while some couples may need to try several times.
According to statistics, around 30% of couples around the world successfully conceive in the first IVF treatment, while 60% of couples successfully conceive in the third treatment. Therefore, it is generally recommended that couples should have at least three IVF treatments to improve the probability of successful pregnancy.
However, the specific number of treatments depends on the couple's personal circumstances. Age is an important factor. For women over 35 years old, the probability of successful treatment will decrease. If the couple's reproductive health status is good, they may successfully conceive in less treatment times.
3. Extension of treatment cycle
Sometimes, the treatment cycle will be prolonged due to special circumstances. These special conditions include poor ovarian function, ovulation disorders, egg membrane syndrome, etc. In addition, if the embryo is not successfully implanted after transplantation, couples may need to carry out multiple treatment cycles to increase the chance of pregnancy.
The prolonged treatment cycle will increase the economic and psychological burden of the couple. Therefore, before IVF treatment, couples need to fully understand their own situation, actively communicate with doctors, and develop appropriate treatment plans.
4. Expert advice
For the treatment cycle and times of IVF, the best practice is to consult a professional fertility expert. Doctors can make a comprehensive assessment based on the couple's situation and provide personalized treatment plans. In addition, couples can also exchange experience and seek support and advice with other couples who have experienced IVF treatment.
summary
The treatment cycle of IVF is generally 4-6 weeks, including ovulation induction, egg collection, in vitro fertilization, embryo culture and embryo transfer. The number of treatments varies from individual to individual, but it is generally recommended that couples receive at least three treatments. The extension of the treatment cycle will increase the burden of the couple, which should be carefully considered. Consulting experts is the best choice for developing treatment plans.
Although IVF treatment requires patience and courage, it has helped countless couples realize their reproductive dreams. I hope every couple can welcome their baby soon.
