Men's Sperm Quality & Testosterone Stack

B84· Mostly solid
Public 08 Apr 2026

Male factor infertility accounts for ~50% of cases & is largely driven by oxidative stress, micronutrient deficiency, & suboptimal testosterone. Ashwagandha has RCT evidence for significantly improving sperm concentration, motility, & testosterone. L-carnitine is the most evidence-backed intervention for sperm motility. CoQ10 & selenium reduce seminal oxidative damage, while zinc is essential for spermatogenesis & androgen synthesis.

Multiple RCTs show 14–167% increases in sperm concentration & motility, plus ~15% increase in testosterone, likely via cortisol reduction & LH normalisation.

Morning on an empty stomach · L-Carnitine or Acetyl-L-Carnitine
Cognitive function in mild cognitive impairment & Alzheimer's diseaseDepressive symptomsMetabolic syndrome biomarkers (waist circumference, blood pressure, lipids, glycemia)

Highest concentration of any organ is in the epididymis; meta-analyses confirm improvements in sperm motility, count, & morphology.

Morbidity & mortality in chronic heart failureStatin-associated muscle symptoms (myalgia, weakness, cramps)

Seminal CoQ10 is directly correlated with motility; supplementation reduces ROS-mediated sperm DNA fragmentation.

Common cold durationRecommended intakes / safety / interactions

Required for testosterone synthesis, sperm capacitation, & acrosome function; deficiency rapidly impairs spermatogenesis.

Daily with food · Selenomethionine
Thyroid function, selenium biochemistry, & immune parametersThyroid antibodies (TPOAb) & thyroid function in Hashimoto thyroiditis

Structural component of sperm mitochondrial capsule; protects against oxidative DNA damage & is required for normal sperm morphology.
