How big can the follicles be before the eggs can be retrieved?

There is a certain normal range for follicles. Follicles are very important to the human body. When we perform IVF, we need to take out the fertilized eggs, but the size of the fertilized eggs should be limited. However, many people do not know its specific size, or have never understood its specific size. So how big can the follicles be before the eggs can be taken out?

Under normal circumstances, when naturally conceiving, many patients will go to the doctor to monitor ovulation. The doctor will tell them that if the follicle grows to 16mm today, or 18mm today, they can go back to have sex. When doing in vitro fertilization, we will give you an ovulation-stimulating injection. After the injection, multiple follicles will develop. You cannot decide whether to retrieve the follicle simply by judging whether a follicle grows to 16 or 18.

The doctor looks at the entire follicle group. Generally speaking, the diameter of the follicles with fertilization function is generally between 15 and 22 mm. The doctor will perform B-ultrasound monitoring according to the situation. If 70% to 80% of the follicles are between 14 and 22 mm, it is considered appropriate and eggs can be retrieved. On the contrary, if there is only one 18 mm follicle and the others are all 10 mm, they will not be retrieved. Therefore, the decision on oocyte retrieval should be based on the average proximal line of the majority of follicle groups.

Under normal circumstances, the follicle will not ovulate until it reaches about 20 mm. Therefore, in vitro fertilization must obtain this kind of mature follicles to increase the chance of success. Relaxing mentally can help improve your endocrine state and promote the development of follicles. The diet should also be diversified, eating more fresh vegetables and fruits, and it is also very important to ensure sleep and exercise moderately.

Under the condition of ovulation induction, the developed follicles are generally larger, larger than the follicles in our normal natural cycle, so the time of egg retrieval is generally determined when the average follicle is 18-20mm, combined with the estrogen level. The size of the follicle is not absolute. We also need to consider her ovulation induction time, her response to medication, and her final estrogen level to determine her egg retrieval time. In addition, we will also observe the follicles through B-ultrasound, the tension of its capsule, the thickness of the membrane, and the size relationship between follicles to make a comprehensive judgment.

The egg needs to grow to about 2 cm in size. It is recommended to keep a good mood. A good mood is a necessary condition for endocrine regulation. Keep a good mood, relieve stress, and keep a regular schedule. It is recommended to eat more black beans, dates, walnuts, fungus and other foods that nourish the liver and kidneys.
