InIVF treatment,"saving embryos" refers to accumulating a certain number of high-quality embryos through multiple ovulation promotion cycles, and then transplanting them when conditions are appropriate. This strategy mainly targets the following groups and needs
Reducethe risk of a single failure
Womenwho are older (such as over 40 years old) or have decreased ovarian function have fewer eggs per promotion, different embryo quality, and lower success rate of single transfer. After 3-4 embryos are collected, centralized transfer can increase the chance of pregnancy. For example, the natural cycle protocol requires multiple embryo collections to reduce the burden of repeated ovulation because of the limited number of eggs retrieved at a single time.
2. Buy time for follow-up treatment
Some patients need to deal with diseases that affect transplantation (such as adenomyosis, endometriosis), or adjust their physical status (such as weight loss and endocrine regulation). Saving enough embryos in advance can avoid further decline in ovarian function due to treatment delays and reduce anxiety during waiting periods.
3. Reduce financial and physical costs
If the number of embryos is insufficient and leads to multiple pre-ovulations, it not only increases medical costs (such as pre-ovulations drugs and egg retrieval operations), but also increases the risk of ovarian hyperstimulation syndrome (OHSS). Saving 4-5 embryos and transplanting them in one go can save about 30% of the total cost and reduce physical damage.
4. Planning for special reproductive needs
Familieswith second/third child plans, or couples who need assisted reproductive technologies (such as egg freezing and genetic screening), can reserve reproductive resources in advance by saving embryos. For example, three generations of test-tube patients need to screen for chromosomal abnormalities in embryos through PGT-A, and saving embryos can avoid the situation of no available embryos due to screening elimination.
5. Optimize embryo screening opportunities
Multiple expulsions can obtain more embryos, and the high-quality embryos with the most development potential can be selected for transfer. Studies have shown that saving embryos provides a basis for screening high-grade blastocysts.
Summary
Saving embryos is not suitable for everyone and needs to be comprehensively evaluated based on age, ovarian reserve, uterine conditions and financial ability.
