This double-blind, randomized controlled trial of 170 clomiphene-resistant PCOS women receiving L-carnitine 3g daily + clomiphene citrate showed dramatic improvements: ovulation rate 64.4% vs 17.4% (control), clinical pregnancy rate 49.4% vs 1.1%, with significantly higher preovulatory follicles >17mm, endometrial thickness (10.1±0.1mm vs 6.8±0.4mm), and higher progesterone levels (13.55±0.99 vs 10.6±0.98 ng/mL, p<0.0001).

This self-controlled propensity-score matched study of 515 IVF patients demonstrated that oral L-carnitine administration until oocyte retrieval significantly improved in vivo oocyte maturation rate (p=0.002), normal IVF fertilization rate (p=0.003), blastocyst formation rate (p=0.003), and yielded more usable blastocysts compared to control cycles, with L-carnitine supporting mitochondrial energy production and lipid metabolism crucial for oocyte quality.

This prospective multi-center observational study of 1,061 infertile women receiving CoQ10 300 mg twice daily (600 mg total) for 2-3 months before IVF/ICSI cycles showed significantly enhanced outcomes: 5 high-quality day-3 embryos per cycle (IQR 3-7), 73% fertilization rate, 82.53% clinical pregnancy rate, and 62.8% implantation rate with no adverse events reported.

This systematic review and meta-analysis of 5 RCTs (449 women with poor ovarian reserve) demonstrated that oral CoQ10 supplementation significantly increased median number of high-quality day-3 embryos (1 vs 0 embryos, p=0.03), higher median embryos per transfer (2 vs 1, p=0.04), and increased proportion of cryopreserved embryos (18.4% vs 4.3%, p=0.012) compared to placebo controls.

This comprehensive meta-analysis of 12 RCTs (2,352 women) demonstrated that vitamin D supplementation, particularly in deficient women (<30 ng/mL) receiving 1000-10,000 IU daily for 30-60 days, significantly increased clinical pregnancy rate (OR: 1.70, 95% CI: 1.24–2.34), improved ovulation rates and fertility outcomes while lowering androgens, LH, FSH, and miscarriage rates in infertile women.

This meta-analysis of 12 RCTs (2,352 women) evaluating vitamin D supplementation on reproductive outcomes revealed that daily dosing (1000-10,000 IU) lasting 30-60 days significantly increased clinical pregnancy rate (OR: 1.70, 95% CI: 1.24–2.34), with optimal benefits in vitamin D-deficient women receiving multicomponent formulations including vitamin D maintaining optimal reproductive hormone balance.

This clinical trial of 115 women with low fertilization rates (<50%) in previous IVF cycles showed that 3 mg melatonin daily plus vitamin E 600 mg significantly reduced intrafollicular oxidative stress markers (8-OHdG and hexanoyl-lysine adduct), with fertilization rate markedly improving after melatonin treatment compared to previous IVF cycles without treatment, demonstrating melatonin's powerful antioxidant protection.

This randomized double-blind trial of 198 PCOS women undergoing intrauterine insemination receiving melatonin 3 mg/day for 12 weeks significantly improved follicle quality, endometrial thickness, and chemical pregnancy rate, while reducing total testosterone, hs-CRP, and oxidative stress markers (MDA), while significantly increasing total antioxidant capacity (TAC) compared to placebo.
