The most important treatment step for IVF is ovulation induction, and the ovulation induction plan is naturally the focus. Many patients are eager to know how long they need to receive ovulation induction injections. It is common to administer the medication for around 10-14 days, but the duration of ovulation stimulation depends on the patient's advantage in the number of follicles or the condition of mature follicles before deciding how to administer the medication, and will try to minimize the harm to women. Let's take a look at how long it takes to do IVF stimulation with the editor of 592 Baby Network.

The use of ovulation promoting drugs usually takes 10-14 days

Natural pregnancy rarely uses ovulation promoting needles and is generally used for in vitro fertilization techniques. With the help of follicle monitoring, the monitoring time requires observation from the 5th grade sinus follicle and simultaneous injection. Usually, it starts on the 9th or 10th day after menstruation in women. The reason for in vitro fertilization can start from the second day, and of course, it can also start from the 5th day, but daily monitoring is required on the 9th day. The injection time varies with different ovulation promotion plans, so it is uncertain how long the ovulation promotion needle will take. In general, ovulation induction needles are usually administered for 10-14 days, and the use time of ovulation induction needles usually needs to be considered based on the patient's physical condition. Age and the most important follicles, early downregulation and drug selection cannot be ignored. Choose a lowering tone and medication. Descending is a necessary stage before descending, in order to prepare for obtaining more follicles. Dafirin (injection), Bayi and other lowering drugs; If common drugs such as Nafen, Pricon, Urotropin, and Chorionic Gonadotropin are chosen, the duration of ovulation induction is directly related to the medication, and both the dosage and time will have an impact on it.

What is the time for promoting ovulation related to?

1. Physical condition.

The physical fitness of women is very important for promoting ovulation, which will directly affect the timing of ovulation injection. Short planned patients may have a shorter duration of use for ovulation promoting injections, while long planned patients may have a longer duration of use. If the body has little response to medication that promotes ovulation, the medication that promotes ovulation may directly fail, so physical condition is very important.

2. The age of the patient.

Age is not only a natural enemy of test tubes, but also has a significant impact on the use of ovulation promoting needles. In many cases, elderly patients will use microstimulation plans. It is difficult to define the duration of ovulation induction, as the timing of ovulation induction varies, leading to the failure of in vitro fertilization. The optimal reproductive age for women is between 23 and 30 years old; The optimal reproductive age for males is 30-35 years old. About 15% of pregnant women over the age of 30 will miscarry; Around the age of 40, about 25% will miscarry; After the age of 45, the abortion rate is as high as 50%.

3. Condition of follicles.

The true injection of ovulation induction is to obtain more eggs. Because some women are sensitive to ovulation promoting drugs and the timing may be advanced, but most of them take 10-14 days, the use of ovulation promoting programs is very flexible. Except for patients with polycystic ovary syndrome, the condition of follicles is the most important.

The above is all about how long it takes to perform in vitro fertilization to promote ovulation. The vast majority of doctors need to determine the injection time by observing follicular development, which may only take 8 or 16 days.
