The clinical goal is not simply to retrieve as many oocytes as possible, but to achieve an appropriate balance between safety and treatment benefit. Too few oocytes may limit the number of available embryos and reduce future transfer opportunities, while an excessive response may increase the risk of ovarian hyperstimulation syndrome (OHSS). Therefore, obtaining an appropriate number of oocytes remains an important goal in individualized ovarian stimulation.\u003C\u002Fp>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">In current practice, ovarian response is estimated using ovarian reserve markers, patient characteristics, previous stimulation history, and clinical experience. However, patients with similar AMH or AFC values may still have noticeably different oocyte yields. This highlights that ovarian response is not determined by a single marker, but by the combined effect of multiple clinical factors. More accurate estimation of expected oocyte yield could therefore provide useful support for optimizing stimulation strategies. AI-based prediction models are being explored as one possible tool to assist this process.\u003C\u002Fp>\n\n\n\n\u003Cfigure class=\"wp-block-image size-large\">\u003Cimg loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"385\" src=\"https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fscreenshot-20260525-183207-1024x385.png\" alt=\"\" class=\"wp-image-796\" srcset=\"https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fscreenshot-20260525-183207-1024x385.png 1024w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fscreenshot-20260525-183207-300x113.png 300w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fscreenshot-20260525-183207-768x289.png 768w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fscreenshot-20260525-183207-1536x578.png 1536w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fscreenshot-20260525-183207.png 1994w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\">\u003C\u002Ffigure>\n\n\n\n\u003Ch2 class=\"wp-block-heading\">\u003Cstrong>Integrating Multidimensional Information\u003C\u002Fstrong>\u003C\u002Fh2>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">Ovarian stimulation decisions already require clinicians to consider patient background, ovarian reserve, and cycle monitoring information together. The innovation of AI is therefore not simply to confirm that one individual marker is important, but to quantify the combined relationships among known clinical variables and patient-specific differences.\u003C\u002Fp>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">For example, similar AMH or AFC levels may correspond to different ovarian responses depending on age, previous response, and stimulation background. Clinical experience can help identify general patterns, but uncertainty remains when multiple variables interact. AI models may help convert these complex combinations into a more continuous and reviewable estimate of response risk.\u003C\u002Fp>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">From this perspective, AI-based oocyte yield prediction is not only about generating a numerical result. It may provide earlier support for cycle management by helping clinicians assess the likelihood of insufficient or excessive response during stimulation. This could inform medication strategy, monitoring intensity, trigger planning, and patient counselling. For the embryology laboratory, estimating the number of MII oocytes may also support workload planning on oocyte retrieval day, including ICSI scheduling, culture resource preparation, and downstream embryo culture capacity.\u003C\u002Fp>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">In this sense, AI may help translate complex clinical judgement into a more structured and reproducible risk assessment. Its value lies not in replacing clinical expertise, but in supporting clinicians and embryology teams with earlier expectations regarding cycle intensity, risk level, and resource needs.\u003C\u002Fp>\n\n\n\n\u003Cfigure class=\"wp-block-image size-large\">\u003Cimg loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"496\" src=\"https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr5_lrg-1024x496.webp\" alt=\"\" class=\"wp-image-797\" srcset=\"https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr5_lrg-1024x496.webp 1024w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr5_lrg-300x145.webp 300w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr5_lrg-768x372.webp 768w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr5_lrg-1536x744.webp 1536w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr5_lrg-2048x992.webp 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\">\u003C\u002Ffigure>\n\n\n\n\u003Ch2 class=\"wp-block-heading\">\u003Cstrong>Early Evidence of Predictive Potential\u003C\u002Fstrong>\u003C\u002Fh2>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">Current findings suggest that AI has potential for predicting both total oocyte number and the number of mature MII oocytes. Total oocyte yield reflects the overall response of a stimulation cycle, while MII oocyte number is more closely related to fertilization, embryo culture, and the practical basis for subsequent laboratory work. For both clinicians and embryologists, these outcomes are not merely recorded results; they can influence cycle evaluation, patient counselling, and future treatment options.\u003C\u002Fp>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">A commonly reported performance metric is mean absolute error, which reflects the average difference between predicted and observed oocyte numbers. Reported errors range from approximately 0.62 to 4.13 oocytes. This suggests that some models can achieve relatively low prediction errors, although performance still varies across studies. For patients with a relatively good ovarian response, a difference of a few oocytes may have limited clinical impact. However, for patients expected to retrieve only a small number of oocytes, a prediction error of three or four oocytes could meaningfully affect clinical interpretation and patient expectations.\u003C\u002Fp>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">It is also worth noting that predicting an exact number may not always be the most clinically useful approach. Some studies suggest that when oocyte yield is predicted as a range rather than a single value, prediction error may decrease substantially, from around 4.21 to 0.7. In real-world practice, this type of stratified prediction may be more useful, as clinicians often need to know whether a patient is at clear risk of insufficient or excessive response, rather than relying on one exact number. In other words, the value of AI lies not only in predicting oocyte yield, but also in supporting clearer and earlier risk assessment.\u003C\u002Fp>\n\n\n\n\u003Cfigure class=\"wp-block-image size-large\">\u003Cimg loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"648\" src=\"https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr4_lrg-1024x648.webp\" alt=\"\" class=\"wp-image-798\" srcset=\"https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr4_lrg-1024x648.webp 1024w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr4_lrg-300x190.webp 300w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr4_lrg-768x486.webp 768w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr4_lrg-1536x972.webp 1536w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr4_lrg-2048x1296.webp 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\">\u003C\u002Ffigure>\n\n\n\n\u003Ch2 class=\"wp-block-heading\">\u003Cstrong>Clinical Value and Current Boundaries\u003C\u002Fstrong>\u003C\u002Fh2>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">One of the most appealing aspects of AI-based oocyte yield prediction is its potential to move decision support earlier in the stimulation cycle. If ovarian response trends can be identified before or early during stimulation, clinicians may have an opportunity to adjust treatment strategy earlier, rather than waiting until follicular development is already close to completion. This could be relevant for starting dose selection, follow-up planning, risk alerting, and patient communication.\u003C\u002Fp>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">However, an important tension remains. Models tend to perform better when they use information collected closer to oocyte retrieval, such as estradiol levels and follicle counts on the trigger day. These variables are highly informative for final oocyte yield, but by that point, the stimulation cycle is nearly complete, and the opportunity for early intervention is limited. In other words, late-cycle prediction may be more accurate, but its clinical value for treatment adjustment may be lower. Earlier prediction is more difficult, but if it can become reliable, it may be more meaningful for clinical decision-making.\u003C\u002Fp>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">For this reason, AI should currently be viewed as an assistive tool rather than an independent decision-making system. A model should not be judged only by its prediction error. It also needs external validation, applicability across different centres and patient populations, interpretability, and safe integration into real clinical workflows. For clinical implementation, stability, generalizability, and explainability are just as important as predictive accuracy.\u003C\u002Fp>\n\n\n\n\u003Cfigure class=\"wp-block-image size-large\">\u003Cimg loading=\"lazy\" decoding=\"async\" width=\"703\" height=\"1024\" src=\"https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr3_lrg-703x1024.webp\" alt=\"\" class=\"wp-image-799\" srcset=\"https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr3_lrg-703x1024.webp 703w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr3_lrg-206x300.webp 206w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr3_lrg-768x1119.webp 768w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr3_lrg-1054x1536.webp 1054w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr3_lrg-1405x2048.webp 1405w, https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002Fgr3_lrg-scaled.webp 1756w\" sizes=\"auto, (max-width: 703px) 100vw, 703px\">\u003C\u002Ffigure>\n\n\n\n\u003Ch2 class=\"wp-block-heading\">\u003Cstrong>Conclusion\u003C\u002Fstrong>\u003C\u002Fh2>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">The value of AI-based oocyte yield prediction is not to replace clinical judgement, but to support more quantitative and reviewable decision-making in individualized ovarian stimulation. By integrating multidimensional clinical information, AI may help clinicians anticipate ovarian response more clearly and move part of the decision-making process earlier in the treatment cycle. It also extends the role of AI in assisted reproduction beyond embryo assessment and into stimulation management.\u003C\u002Fp>\n\n\n\n\u003Cp class=\"wp-block-paragraph\">Nevertheless, this field still requires further clinical validation. A truly useful AI tool should not only predict accurately, but also perform consistently across different centres, patient populations, and real-world workflows. Only when such models can help optimize medication strategies, reduce risk, improve patient management, and support laboratory planning will they become reliable decision-support tools in individualized assisted reproduction.\u003C\u002Fp>\n",false,"https:\u002F\u002Fwp.fertsy.com\u002Fwp-content\u002Fuploads\u002F2026\u002F05\u002FChatGPT-Image-2026年5月25日-18_46_43_compressed.png",[14],2,[],0,1780056203842]
