Conclusion: Need > 51 ng avoid premature ejaculation

Conception and vitamin D snapshot as of 2012
I have always lived in Western Washington, which has the most clouds in the US and had previously suffered from
- premature ejaculation
- sore tibias and "growing pains" as a child
- back pain (which was the reason I started VitaminDWiki)
- overweight (have since lost > 20 pounds)
- dental caries, bleeding gums, fissured tongue, cracked teeth
- common cold
- restless legs
all of which are associated with low vitamin D,
some of which are also associated with low Magnesium, Boron, Silica, Exercise
They have all gone away after my getting a good level of vitamin D
Also, I now have more muscle (age 72) than anytime previously in my life

To compare serum level of vitamin D [25(OH)D] in patients with life-long premature ejaculation (LPE) versus healthy controls.
Healthy married potent males were recruited from February 2017 to January 2018. Group A included 40 patients suffering from LPE who were compared versus 40 healthy controls (Group B ). Participants suffering from hormonal disorders, obesity, neurological, psychological, or chronic diseases or taking medications that may affect ejaculatory function, serum level of vitamin D, or the accuracy of intra-vaginal ejaculation latency time (IELT) were excluded. LPE was self-reported by the patients with subsequent feelings of frustration and measured by premature ejaculation diagnostic tool (PEDT) and IELT using stopwatch handled by their partners. 25(OH)D was measured by obtaining 2 ml of venous blood. Statistical analysis was performed using Student t, Mann–Whitney, Chi square tests, logistic regression analysis, and Spearman correlation.
Sixteen (20%) participants had vitamin D insufficiency/deficiency. All of them were in PE group. 25(OH)D correlated significantly with IELT (r2 = 0.349; p < 0.001) and PEDT (r2 = 0.425; p < 0.001). There was no statistically significant difference in age (p = 0.341), BMI (p = 1) or IIEF-5 (p = 0.408) in both groups. 25(OH)D was significantly lower in patients than controls (35.75 vs. 58.92 ng/ml, p < 0.001). ROC analysis revealed that the best cut-off value of 25(OH)D to detect patients suffering from LPE was 50.65 ng/ml with a sensitivity and specificity of 85% for both. 25(OH)D remained a significant risk factor for LPE in the logistic regression analysis (p < 0.001).
ConclusionsL The current study showed that vitamin D has significant association with LPE and correlates significantly with IELT and PEDT.

PURPOSE: To investigate the relationship between 25-hydroxyvitamin D (25 (OH) D) levels and acquired premature ejaculation (PE).
MATERIALS AND METHODS:
A total of 97 patients with acquired PE and 64 healthy men as a control group selected from volunteers without PE attending our Andrology Outpatient Clinic between November 2016 and April 2017 were included the study. All patients were considered to have acquired PE if they fulfilled the criteria of the second Ad Hoc International Society for Sexual Medicine Committee. Premature ejaculation diagnostic tool questionnaires were used to assessment of PE and all participants were instructed to record intravaginal ejaculatory latency time. Vitamin D levels were evaluated in all participants using high performance liquid chromatography method included in the study.
Compared to men without PE, the patients with acquired PE had significantly lower 25 (OH) D levels (12.0 ± 4.5 ng/mL vs. 18.2 ± 7.4 ng/mL, p < 0.001). In the logistic regression analysis, 25 (OH) D was found to be an independent risk factor for acquired PE, with estimated odds ratios (95% CI) of 0.639 (0.460-0.887, p = 0.007) and the area under curve of the ROC curve of 25 (OH) D diagnosing acquired PE was 0.770 (95% CI: 0.695 to 0.844, p < 0.001). The best cut-off value was 16 ng/mL with a sensitivity of 60.9%, specificity of 83.5%, PPV of 70.9%, and NPV of 76.4% to indicate acquired PE.
This study demonstrates that lower vitamin D levels are associated with the acquired PE. The result of our study showed that the role of serum vitamin D levels should be investigate in the etiology of acquired PE. Perhaps supplementation of vitamin D in men with acquired PE will ameliorate the sexual health of these patients.
