Vitamin B₁₂ Is Associated with Higher Serum Testosterone Concentrations and Improved Androgenic Profiles Among Men with Infertility.

ABSTRACT:

Background

Infertility impacts 16% of North American couples, with male factor infertility contributing to ∼30% of cases. Reproductive hormones, especially testosterone, are essential for spermatogenesis. An age-independent population-level decline in testosterone concentrations over the past few decades has been proposed to be a consequence of diet and lifestyle changes. Vitamin B₁₂ is present in the testes and has been suggested as an adjuvant nutritional therapy for male infertility due to its potential to improve sperm parameters. However, evidence examining the relationship between vitamin B₁₂ and reproductive hormones is limited.

Objectives

The objective was to cross-sectionally examine the relationship between serum vitamin B₁₂ and mal
