How long does IVF take?
In vitro fertilization (IVF) is a kind of reproductive method that transfers the embryos after IVF to the mother's uterus for development. The success rate of IVF is related to many factors, among which the medication time is an important factor. The time of IVF medication will be described in detail in the following four aspects: drug preparation, drug treatment cycle, individual differences and drug monitoring.
1、 Drug preparation
In the process of IVF, a series of drugs need to be prepared first. These include ovulation promoting drugs, luteinizing hormone, antagonists and replacement hormones used to promote follicular development. When doctors confirm that a patient is suitable for IVF, they usually make individualized medication plans according to the specific conditions of the patient. According to the different menstrual cycle of women, the time of drug preparation will change.
Before IVF operation, female patients usually need to recover properly to ensure the best physical condition. The drug preparation at this stage generally takes 2 weeks to ensure that women are fully prepared.
Next, according to the characteristics of the patient's menstrual cycle, the doctor will start to inject ovulation promoting drugs to the patient from the third to the fifth day of menstruation to promote follicular development. This phase usually lasts 10 to 12 days.
2、 Drug treatment cycle
The drug treatment cycle is another important point in the IVF process. Generally speaking, the whole cycle from the start of medication to the date of egg retrieval takes about 2 to 3 weeks. The date of oocyte retrieval depends on the follicular development and individual differences.
In the drug treatment cycle, female patients need to be injected with drugs every day to promote follicular development. The injection is usually carried out at night, and is guided and supervised by a doctor. In addition, regular ultrasonic examination and blood examination are also required to monitor the follicular development and timely adjust the drug dosage.
Generally speaking, the date of egg retrieval is usually when the follicle diameter reaches 18 to 20 mm. The time of the whole drug treatment cycle will vary according to the follicular development and individual differences.
3、 Individual differences
Individual differences are another important factor affecting the duration of IVF medication. Everyone's physical condition and physiological characteristics are different, and their reactions to drugs are also different. During the treatment, doctors will make individualized adjustments according to the specific conditions of patients to ensure the effect and safety of drugs.
Some female patients may need multiple cycles of medication to succeed. Therefore, individual differences not only affect the duration of medication, but also affect the duration of the whole IVF.
4、 Drug monitoring
Drug monitoring is a key link in the process of IVF medication, which can help doctors accurately evaluate the treatment response of patients and adjust the drug dose. In the course of medication, doctors will regularly conduct ultrasonic examination and blood examination to monitor follicle development, hormone levels, ovulation time and other indicators.
Drug monitoring usually needs to be continued several times to ensure proper drug adjustment. According to the monitoring results, doctors will make corresponding adjustments according to the needs of individualization to improve the success rate.
summary
To sum up, the administration time of IVF mainly includes four aspects: drug preparation, drug treatment cycle, individual differences and drug monitoring. Drug preparation usually takes 2 weeks, and the drug treatment cycle is about 2-3 weeks. Individual differences will affect the duration of the whole IVF. Drug monitoring is the key to ensure therapeutic effect and adjust drug dosage. Through reasonable drug use and monitoring, the success rate of IVF can be improved, bringing good news to patients.
