Introduction
It is generally recommended to prepare for egg retrieval when the follicle size reaches 17-18 mm and there are 2-3 high-quality follicles. Ovulation should be monitored using ultrasound or ovulation test strips before egg retrieval. Additionally, it is important to stay relaxed and avoid excessive stress prior to the procedure. If egg quality is poor, folic acid supplementation may be taken under medical guidance for three months before egg retrieval to improve egg quality.
Generally, it is usually recommended to prepare for egg retrieval when the follicles reach a size of 17-18 millimeters, but this should be considered in combination with the number of mature follicles. Additionally, certain considerations should be kept in mind regarding the egg retrieval procedure. A detailed explanation is as follows:
When the follicle diameter reaches 17-18 millimeters, it indicates that the follicle has developed to maturity and is capable of being fertilized. If there are 2-3 high-quality mature follicles simultaneously, the follicles can be retrieved under ultrasound guidance using a puncture needle, as directed by a physician.
Prior to egg retrieval, it is advisable to use ovulation test strips or ultrasound to monitor ovulation, to better understand the size and number of follicles. It is also important to stay relaxed and avoid excessive anxiety. Three months before egg retrieval, it is recommended to take folic acid as directed by a physician to improve egg quality.
The timing mentioned above generally applies to most women, but if there are special circumstances, the timing of egg retrieval should be determined individually. If you have any questions regarding this, it is advisable to consult your doctor before proceeding with egg retrieval.
