Serum magnesium is linked with sperm concentration, motile sperm count and serum anti-Müllerian hormone in infertile men.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

What is the relationship between serum magnesium, semen quality and reproductive hormones in infertile men?

Who Took Part

The study group was 330 men.

By PubMed's age tags, the people studied were adults, men only.

Each participant underwent a physical examination and had blood and semen parameters assessed.

Thirty-one men were excluded due to missing serum magnesium, leaving 299 men stratified by serum magnesium tertile.

How the Study Was Run

In design terms this was a randomized and placebo-controlled study.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

What Was Measured

Topics PubMed links to this paper include Anti-Mullerian Hormone, Cholecalciferol, Infertility, Male, Magnesium, Sperm Count, Sperm Motility and Secondary Data Analysis.

Author keywords: Semen quality, Serum AMH, Serum magnesium and Vitamin D.

What This Means in Plain Language

The paper is a randomized and placebo-controlled study of Vitamin D, K2, Magnesium and Zinc in 330 men.

With several hundred people or more, it is a fairly large study for this kind of research.
