Ovulation induction of IVF is the beginning of the cycle, there are many ovulation induction programs, long programs, short programs, ultra-long programs, each patient's situation is different, the programs used are different, today, we will introduce the difference between the long program and the short program of IVF.
Maybe many people will have a question in their minds when they see the short plan, long plan, and ultra-long plan: is it because the time of the short plan is relatively short, so it is better and faster to choose the short plan?
First of all, we need to realize that the choice of the length of the program is determined according to the woman's physical condition, and if the woman's ovarian function is good, the long-term program will be implemented; If the woman's ovarian function is weak, a short regimen is used.
What are long-term, short-term, and extra-long solutions?
The long regimen lasts longer than the short regimen, but it can induce ovulation well, the ovarian response is good, the follicle growth can be better controlled with medication, and there will be no early ovulation under normal circumstances.
The ultra-long regimen is used for a longer period of time, with an effective GNRH agonist for one to several months prior to ovulation induction. It is mainly used for patients with hyperhemia, endometrial translocation, and polycystic ovaries.
Although the duration of the short regimen is short, the ovulation induction effect is relatively poor, and the ovarian response is more unstable and inconsistent. For example, sometimes a large follicle will appear, which inhibits the growth of other follicles, and only one follicle grows, and if ovulation promotion fails, early ovulation will occur. Therefore, under normal circumstances, doctors will choose the long plan, and the short plan is out of consideration when the woman's ovarian function is not good, and the long plan is worried that the long plan will not promote the follicles to choose the backup plan.
