Vitamin D greatly improves Fertility
- Vitamin D is needed for human fertility – goal is 50 ng – Sept 2018
- In-vitro Fertilization costs at least 10,000 dollars, Vitamin D costs 5 dollars
- Women were 50X more likely to be fertile if just 1 ng higher level of vitamin D – Nov 2024
- Infertile patients 1.7X more-likely to become pregnant if take Vitamin D – meta-analysis Feb 2023
- Live birth 1.7 X more likely after IVF if good level of vitamin D – meta-analysis Aug 2020
- If diagnosed infertile, more likely to have live birth if Vitamin D fortification – Feb 2020
- Preconception vitamin D is great - every extra 10 ng associated with 10 percent more likely to have live birth – Aug 2018
- Women with more than minimum vitamin D were 3.4 X more likely to achieve pregnancy and 1.6 X more likely to have live births – June 2017
- Assisted Reproduction – 5 studies concluded vitamin D repletion helps – Review March 2015
- Pregnancy success increased 30 percent if sunny (or vitamin D) one month earlier – June 2015
- IVF 4X more successful for white women with lots of vitamin D – many studies
Increased male Vitamin D increases fertility
- Birth rates doubled with Vitamin D - 300,000 for infertile men – RCT Nov 2017
- Higher vitamin D results in 22% fewer abnormal sperm (Mendelian analysis) – May 2024
- Conception was 3.7X more likely if the male had a good level of Vitamin D – July 2022
- Far better sperm in fertility clinic if more than 30 ng of Vitamin D - June 2022
- Fertility (sperm) associated with vitamin D – meta-analysis Sept 2019
- Infertility - 71 percent of the time of BOTH partners had less than 20 ng of Vitamin D – Aug 2017
- Male fertility 4 X higher if high Vitamin D – Nov 2015
- Vitamin D somewhat assists reproduction – both the mother and the father – May 2014
Decreased Fertility if decreased Vitamin D Receptor

BACKGROUND:
Anti-Müllerian hormone (AMH) is considered to be one of the most significant indicators of women's fertility. Many studies have shown that vitamin D may modify human reproductive functions; however, the results are conflicting. The composition of follicular fluid (FF) creates the biochemical environment of the oocyte and affects its quality, which later determines the embryo quality. In this study, we aimed to revise with advanced statistical techniques the relationship between AMH and vitamin D in FF.
METHODS:
The study was designed as a prospective single-center study in infertile patients with AMH ≥ 0.7 ng/mL who underwent controlled ovarian hyperstimulation for in vitro fertilization. AMH and vitamin D levels in FF were measured. Next, the standard and advanced statistical (including segmented regression) techniques were applied.
RESULTS:
We observed a negative linear correlation between levels of AMH in serum and FF and total vitamin D concentrations up to approximately 30 ng/ml; with a statistically significant relationship in FF. Beyond that concentration, the trend was positive but statistically insignificant.
CONCLUSIONS:
As an existing "change-point problem" was noticed, we suggest segmentation in the relationship between vitamin D and AMH during infertility treatment.
