What is the difference between a long and short IVF regimen

The main difference between time and how much money is spent. The long plan needs to be lowered, and then the stimulation is carried out, the short program is both downgraded and promoted synchronously, and some do not need to be lowered to directly promote the discharge, the short program is relatively short, so the cost will be less than the long program, but this is not something you can choose, because the choice of using a long program or a short program is based on your ovarian function and your age, in a word, listening to the doctor's arrangement is the best, good pregnancy!

For patients with regular ovulation, a long natural cycle regimen can be chosen, and for patients with irregular ovulation, an oral contraceptive prolongation regimen can be chosen. The natural cycle long regimen is generally from the 1st to 2nd day of menstruation, or 5-7 days after ultrasound monitoring ovulation. The lengthened regimen of oral contraceptives is generally on the 16th to 18th day after oral contraceptives, and there is no abnormality in B-ultrasound, and the use of dufferin is started to reduce the condition.

Generally, after about 14-20 days, the standard of downregulation is reached, and after the standard is reached, the drug is used to induce ovulation. Generally, it takes about 10-14 days for follicles to mature, and then hcg ovulation injection, 36-38 hours after the injection, the male sperm is retrieved at the same time as the egg retrieval, and then handed over to the embryo laboratory personnel for embryo culture, embryo culture is followed by embryo transfer, and the remaining embryos are frozen. Blood was drawn 14 days after the transplant to check the blood for HCG, and if the HCG is positive, it means that the pregnancy was successful.

Fetal preservation after pregnancy** is confirmed, followed by obstetric follow-up.

IVF long programIt is the use of GNRHA on the 21st day of the previous menstrual cycle (called the mid-luteal phase), and the use of GNRHA does not affect the onset of menstruation; On the 10th day of GNRHA use, that is, on the 3rd day of this menstruation, ovulation induction drugs were used, and then B ultrasound was performed irregularly to monitor the growth of follicles, and blood was drawn to measure estrogen content, and the ovarian response to the drug was judged according to the results of B ultrasound and estrogen, and the dose of ovulation induction drugs was adjusted accordingly; Until the doctor says that the follicle has matured, 10,000 IUHCG is injected on the same day (usually in the evening to promote the maturation of the egg; Eggs can be retrieved 36 hours after the HCG injection (8 a.m. on the 3rd day of the HCG injection day).

IVF short programOn the 10th day of GNRHA use, that is, on the 3rd day of this menstruation, ovulation induction drugs are used, and then B ultrasound is performed irregularly to monitor the growth of follicles, and blood is drawn to measure estrogen content, and the ovarian response to the drug is judged according to the results of B ultrasound and estrogen, and the dose of ovulation induction drugs is adjusted accordingly; Until the doctor says that the follicle has matured, 10,000 IUHCG is injected on the same day (usually in the evening to promote the maturation of the egg; Eggs can be retrieved 36 hours after the HCG injection (8 a.m. on the 3rd day of the HCG injection day).

In contrast, the pregnancy success rate was slightly higher with the long regimen than with the short regimen. Most people are candidates for a long regimen, but for some older patients or patients with a poor ovarian response, a short regimen is more appropriate because the downregulation suppresses the secretion of their own follicle growth hormone, which may make the follicles less likely to be produced or have less follicle growth.

IVF long program

The long regimen is mainly suitable for patients with good ovarian reserve. In general, a long regimen is usually started on the 21st day of the previous menstrual period, and ovulation induction drugs are started on the 10th day of the 10th day of the previous menstrual period, followed by regular ultrasound to monitor the growth of follicles, and blood is drawn to measure the estrogen content, and the dose and duration of the stimulation drugs are adjusted according to the monitoring results.

Advantages of the long IVF program: Although the long program lasts for a long time, it has a good stimulation effect, good ovarian response, and the growth of follicles can be controlled with medication, and there will generally be no early ovulation, which effectively increases the success rate.

IVF short program

The short regimen is mainly suitable for older women with poor ovarian reserve. Start injecting dufferin on the 2nd to 3rd day of menstruation, inject follicle-stimulating hormone in the afternoon of the next day, and then perform B ultrasound to monitor the growth of follicles from time to time, and take blood to measure estrogen content, judge the ovarian response to the drug according to the monitoring results, and adjust the dose of ovulation induction drugs until the B ultrasound monitoring follicles have matured, about 8-12 days of ovulation induction drugs, and eggs can be retrieved on the 3rd day of HCG injection.

The advantages of the short IVF program: GN ovulation induction is small, the use time is short, simple and flexible.

In the process of IVF, there is a step in egg retrieval. Before the egg retrieval, the doctor will use a series of drugs to control the development of the woman's follicles, and after the multiple follicles mature and are discharged. During this period, the amount of time each person uses the drug is different, so there are long and short regimens.

Reproductive medicine experts remind: whether you choose a long or short IVF plan, it needs to be decided according to the woman's age and ovarian function. Generally speaking, if you are young and have good ovarian function, it is advisable to choose a long plan; If you are older and have poor ovarian function, you may be able to choose a short regimen.

It depends on your couple's physical condition and whether the hospital you choose is the best at handling your fertility challenges. The average success rate in Thailand is around 60%, and some hospitals will have a higher success rate, and the success rate will be higher at a younger age. - From the Guardian Number: zscc933

IVF long program

Different women have different conditions and different cycles in the long program process. In general, a long regimen is usually started on the 21st day of the previous menstrual period, and ovulation induction drugs are started on the 10th day of the 10th day of the previous menstrual period, followed by regular ultrasound to monitor the growth of follicles, and blood is drawn to measure the estrogen content, and the dose and duration of the stimulation drugs are adjusted according to the monitoring results.

Indications for the long regimen of IVF: women who are younger and have good ovarian reserve.

IVF short program

Start injecting dufferin on the 2nd to 3rd day of menstruation, inject follicle-stimulating hormone in the afternoon of the next day, and then perform B ultrasound to monitor the growth of follicles from time to time, and take blood to measure estrogen content, judge the ovarian response to the drug according to the monitoring results, and adjust the dose of ovulation induction drugs until the B ultrasound monitoring follicles have matured, about 8-12 days of ovulation induction drugs, and eggs can be retrieved on the 3rd day of HCG injection.

Indications for short IVF regimens: older women with poor ovarian reserve.

Compared with the long plan with better ovulation induction effect, the short plan has an unstable effect and the quality of the follicles is quite different. Short regimens** sometimes result in a large follicle that inhibits the growth of other follicles, resulting in uneven follicle quality and possibly only one follicle in the end.

However, it does not mean that the short regimen is worse than the long regimen, but patients need to choose the appropriate stimulation regimen according to their own ovarian conditions, so as to get more eggs and improve the success rate of IVF.
