The auxiliary effect of oral nutritional supplements on fertility in women with diminished ovarian reserve: a systematic review and meta-analysis
Bibliographic record
Abstract
Objective Evaluate the adjuvant effects of oral nutritional supplements including vitamins, coenzyme Q10, and dehydroepiandrosterone (DHEA) on fertility in patients with diminished ovarian reserve (DOR).Methods We conducted a generalized explore of 9 databases established as of September 1, 2024. Mainly studing and analyzing outcomes including serum follicle stimulating hormone (FSH) levels, anti Mullerian hormone (AMH) levels, antral follicle count (AFC), retrieved oocytes, and clinical pregnancy rate with the methodology of a systematic review and meta-analysis. The inclusion quality of each experiment was evaluated through the Newcastle Ottawa Scale (NOS).Results The meta-analysis consisted of 16 studies with 2773 participants. A review of existing evidence suggested that oral nutritional supplements, including vitamins, coenzyme Q10, and DHEA, could significantly lower FSH levels (SMD = −0.67, 95% CI [−0.94, −0.40], p < 0.0001), rise AMH levels (SMD = 0.35, 95% CI [0.02, 0.69], p = 0.04), AFC counts (MD = 0.99, 95% CI [0.28, 1.69], p = 0.006), retrieved oocyte counts (MD = 0.88, 95% CI [0.54, 1.23], p < 0.0001), and clinical pregnancy rate (OR = 1.70, 95% CI = [1.35, 2.13], p < 0.0001). Oral nutritional supplements for more than 2 months have a better effect on lowering FSH levels, raising AMH levels, and oocyte numbers (p < 0.05). In addition, we found that the use of coenzyme Q10 alone was more effective than the use of DHEA alone through subgroup analysis. There was a remarkable correlation (p < 0.05) between the use of both nutritional supplements and the decrease of FSH, as well as the increase of AMH, AFC, and oocytes retrieved. We used sensitivity analysis to conclude that our summary results are robust.Conclusions Oral nutritional supplements, including vitamins, coenzyme Q10, and DHEA may be a simple and relatively low-risk treatment option to assist in improving fertility in women with DOR.Registration number CRD42024580831.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
