Eggs play an important role in childbirth. Every woman of childbearing age has a relatively large number of eggs in her body, but only mature eggs will be released. If there are no eggs that have not matured, their function will be incomplete. So, how old is the IVF follicle considered mature?
Usually, the dominant follicles are relatively large, around 10-18 millimeters in size, and only one high-quality follicle will be discharged, while the remaining follicles will shrink and be absorbed by the body. When doing in vitro fertilization, in order to obtain dominant follicles, ovulation induction is performed. At this time, the follicles are usually larger, slightly larger than those in the normal natural cycle, usually reaching 18-20 millimeters. Before egg retrieval, the timing of egg retrieval should be determined based on the female's estrogen level at that time.
The size of follicles is also not absolute, and it needs to be determined at the appropriate time and according to the estrogen level of the female body. Usually, B-ultrasound can be used to check the quality of follicles, taking into account their tension, membrane thickness, and other factors.
Women need to stabilize their emotions during egg retrieval, as emotions can also affect the development of follicles. If the quality of follicles is poor, women do not need to worry too much. Doctors will adjust the ovulation promotion plan according to the specific condition of the female body, and help women retrieve high-quality eggs as soon as possible.
Couples who want to have in vitro fertilization should clarify the relevant information before undergoing the procedure to avoid delaying the egg retrieval process due to carelessness, which may not be worth the loss.
