How many times does IVF take?
In vitro fertilization (IVF) is a kind of assisted reproductive technology, which combines eggs and sperm in vitro, cultivates them into embryos, and then transfers them to the female uterus, so as to achieve pregnancy. The medication cycle of IVF is a very important link. Next, we will elaborate on the relevant information of IVF medication cycle from four aspects: drug selection, medication dose, medication time and medication duration.
Drug selection
The drugs commonly used in IVF medication cycle include ovulation promoting drugs and prescription drugs. Ovulation promoting drugs are mainly used to stimulate ovarian development and promote the maturation of eggs. Common ovulation promoting drugs include human chorionic gonadotropin (hMG), follicle stimulating hormone (FSH), etc. Auxiliary prescription drugs are used to regulate hormone levels and increase fertilization opportunities. Common auxiliary prescription drugs include Surulen, etc.
According to different patients' conditions, doctors will develop individualized medication plans to ensure that the choice of drugs is appropriate.
Dosage
In the IVF medication cycle, the choice of drug dosage should be adjusted according to individual conditions. Too low a drug dose may lead to inadequate egg development, while too high a drug dose may increase the risk of ovarian hyperstimulation syndrome (OHSS).
The doctor will determine the dosage according to the patient's age, ovarian reserve, follicular development and other factors. Generally, the initial dose is low, and then it is adjusted according to the monitoring results of follicle size and hormone level to achieve good therapeutic effect.
Administration time
The medication period of IVF is generally about 14 days. At the beginning of the medication cycle, progesterone inhibition is usually carried out first, that is, progesterone is orally or injected to inhibit the formation of corpus luteum, and then ovulation promoting drugs are used to stimulate ovarian development. Artificial fertilization or in vitro fertilization is carried out before and after the ovarian ovulation period, and the fertilized eggs are finally implanted into the uterus for pregnancy.
The whole medication process needs to be monitored and adjusted under the guidance of doctors to ensure the accuracy of medication time and good treatment effect.
Duration of medication
The duration of IVF medication cycle is generally about one month. After the above medication time, if the fertilized egg is successfully implanted into the uterus and pregnancy occurs, the medication cycle ends. If the pregnancy is not successful, the next medication cycle can be started again after a rest period.
Everyone's physical condition and reaction are different, and some patients may need multiple medication cycles to successfully pregnancy. The doctor will make assessment and suggestions according to the specific situation of the patient, and formulate a suitable treatment plan.
Summary
The drug cycle of IVF needs to be carried out many times, and the drugs used include ovulation promoting drugs and auxiliary prescription drugs. The choice, dosage and time of drugs need to be adjusted according to the individual conditions of patients. The medication cycle is generally about 14 days, while the duration of medication is generally about one month. Each patient's situation is different, and some people may need to take multiple drug cycles to succeed in pregnancy. Therefore, before IVF treatment, it is recommended that patients fully communicate with doctors to understand comprehensive treatment information so as to make wise decisions.
