Generally speaking, the duration of ovulation-stimulating injections is 10-14 days, but the specific number of days depends on the growth of the follicles, and the dosage is determined based on the condition of the follicles.

3. Why do IVF patients need ovulation-stimulating injections?

In a woman's natural ovulation cycle, only one dominant follicle develops, and only one embryo is formed after fertilization. There is no choice during embryo transfer, so controlled superovulation is needed to obtain multiple healthy eggs. This will allow more embryos to be cultivated, from which high-quality embryos can be selected for transplantation, which can increase the chance of pregnancy.

After the IVF ovulation-stimulating injection, the hospital will monitor the development of the eggs through B-ultrasound. When the diameter of 2 or more follicles is greater than 1.8-2 cm and the estrogen level is consistent with the number of follicles, the eggs at this time have the ability to mature. The doctor can then inject human chorionic gonadotropin to promote the maturation of the eggs in the follicles, and then consider egg retrieval.
