The IVF process is full of unknowns and expectations for every woman. Especially during the ovarian stimulation phase, some women retrieve many eggs, while others retrieve only a few. Why is there such a difference? The experiences of Xiaowei and Xiaoya perfectly illustrate this. They both had egg retrieval surgery on the same day; Xiaowei had 10 eggs retrieved, while Xiaoya only had 4. This left Xiaoya full of doubts: Why such a disparity? Does a low egg retrieval count mean a lower success rate?

 

Dr. Nathan Zhang, founder of IVF USA and a leading expert in the field of assisted reproduction in the US, explained that in the IVF process, the number of eggs retrieved does affect the number of subsequent embryos, which in turn impacts the ultimate chance of pregnancy. However, more eggs are not always better. In fact, egg quality is more important than quantity. If a woman retrieves too many eggs at once, it may increase the risk of Ovarian Hyperstimulation Syndrome (OHSS). Once the number of retrieved eggs exceeds 15, the incidence of OHSS significantly increases, while the live birth rate does not significantly improve with the increased number of retrieved eggs.

 

So, what factors influence the number of eggs retrieved? The following aspects play a crucial role:

 

Age: As women age, their ovarian function gradually declines, and both the quantity and quality of eggs are affected. The older the age, the fewer eggs may be retrieved, which is why younger women typically retrieve more eggs.

 

Follicle Quality: The quality of follicles during ovarian stimulation is closely related to the dosage and timing of medication. Precise medication control ensures the effectiveness of stimulation, leading to high-quality follicles. If medication is used improperly or genetic issues affect follicle quality, the number of retrieved eggs will naturally decrease.

 

Retrieval Timing: The timing of egg retrieval is also critical. Doctors need to select the optimal time for retrieval based on the real-time development of the follicles. Retrieving too early or too late can affect the final number and quality of eggs obtained.

 

Medical and Physician Skill Level: Egg retrieval is a delicate procedure. The advancement of medical equipment and the doctor's experience level both influence the final outcome. Professional clinics and experienced doctors can not only ensure the smooth operation but also make adjustments during the process based on the patient's specific situation. Furthermore, throughout the entire IVF treatment process, laboratory technology, the doctor's clinical experience, and the personalization of the treatment plan are equally crucial.
