- 50,000 every 5 days for 8 weeks
- 100,000 every week for 6 weeks
- 50,000 weekly for 12 weeks

Conception and vitamin D snapshot as of 2012
- 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
- Infertility treatment needs to achieve at least 30 ng of vitamin D – May 2019
- Vitamin D is needed for human fertility – goal is 50 ng – Sept 2018
- Preconception vitamin D is great - every extra 10 ng associated with 10 percent more likely to have live birth – Aug 2018
- In-vitro Fertilization costs at least 10,000 dollars, Vitamin D costs 5 dollars

25-Hydroxy Vitamin D3 is known to have an effect on reproductive system in both genders and may change the semen parameters in men.
Our study aimed to evaluate the effect of oral vitamin D3 supplementation on spermogram quantitative and qualitative parameters in infertile men.
Materials and Methods
This study was a triple-blind randomized controlled trial involving 62 infertile men with impaired spermatogonial tests. They were randomly divided into placebo and D3-supplemented groups. Spermograms and tests for LH (Luteinizing Hormone), FSH (Follicle Stimulating Hormone), TT (Total Testosterone), FT (Free Testosterone), SHBG (Sex Hormone Bonding Globulin), FAI (Free Androgen Index) and vitamin D3 levels were performed before and after the intervention.
There were no significant differences between the two groups in parameters of the spermograms or serum levels of LH, FSH, TT, and FAI. In the intervention group, SHBG was significantly decreased after intervention (p = 0.01) and there was a significant increase in FT in the placebo group (p = 0.03).
The intake of vitamin D3 did not change the quality and quantity of spermograms and serum levels of LH, FSH, TT, and FAI but affected FT and SHBG. Further studies are still needed to clarify the biological role of vitamin D3 on fertility particularly on male fertility. This study lays a foundation for more extensive studies on male infertility.
