Mature oocytes are retrieved after ovulation induction and stored in liquid nitrogen following vitrification, preserving the possibility of thawing, fertilization and transfer later. Generally, the younger the woman, the better the egg quality.

The following is for reference only; suitability must be determined by a physician based on test results.
The overall process is as follows; actual milestones are adjusted according to test results and individual response.
AMH, six-item hormone panel and antral follicle count to estimate ovarian reserve
Individualized stimulation protocol based on age and ovarian reserve
About 10–14 days of stimulation and dynamic monitoring, with dose adjustments
Ultrasound-guided aspiration under intravenous anesthesia, with several hours of post-operative observation
Mature oocytes are rapidly frozen and placed into storage tanks
Storage status is confirmed annually; if use is required, thawing and ICSI are arranged
These are our specific requirements at the execution level, and they can also be inspected on site during a visit.
Protocol adjusted to ovarian reserve, balancing egg yield and physical tolerance
Senior embryologists assess oocyte maturity under microscopy before freezing
Thawed oocytes are fertilized by intracytoplasmic sperm injection to improve the chance of fertilization
Dedicated number and storage position, with regular follow-up by a Chinese-speaking advisor
It is generally recommended before age 35; egg quantity and quality decline with age, and the decision should be based on AMH and antral follicle count.
There is a certain loss rate during thawing, and tolerance to freezing damage varies between individuals; a younger age is generally more favorable.
Most protocols take about 10–14 days, with multiple ultrasound and blood tests during this period; follow your physician's instructions.
