At the beginning of IVF, only eggs can be retrieved during the natural cycle of women, usually only one. With the development of drugs, doctors can use drugs (mainly follicle-stimulating hormone) to stimulate the development of a batch of eggs in the ovaries, which leads to ovulation induction programs. So what are the ovulation induction options?
There are many ovulation induction regimens: mid-trimester long luteal regimen, ultra-long regimen, short regimen, ultra-short regimen, antagonist regimen, microstimulation regimen, ovulation induction regimen in a hyperprogestin state, and so on.
According to the amount of follicaridin used, it can be roughly divided into two types: conventional dose stimulation regimen and microstimulation regimen. Micro-stimulation regimen, follicle-stimulating hormone dosage of less than 150 IU per day, combined with clomiphene, letrozole and so on. In contrast, the conventional dose stimulation regimen, with follicle-stimulating hormone dosages of more than 150 IU per day, combined with GnRh agonists or antagonists. At present, the mainstream regimen is a stimulus regimen of conventional doses of follicle-stimulating hormone combined with antagonists, referred to as antagonists.
Current studies have shown an increase in the dose of follicle-stimulating hormone and a corresponding increase in the number of eggs obtained. The choice of different regimens is based on the patient's own ovarian reserve and how the ovaries respond to ovulation-stimulating drugs. For example, microstimulation regimens are mostly used in patients with poor ovarian function. The goal of each ovulation induction program is to optimize the number or quality of eggs that individuals are expected to receive.
Good embryos and good lining are the guarantee of IVF success. A good embryo depends on the quality of the sperm and egg. On the basis of quality, increasing the number of eggs obtained can increase the success rate of pregnancy. The number of eggs obtained is related to the woman's own ovarian reserve and the response of the ovaries to ovulation-stimulating drugs.
Therefore, if you want to improve the success rate of pregnancy and improve the quality of sperm and eggs, please ask a professional doctor to choose the ovulation promotion program that is most suitable for your own situation.
