Ginger and Testosterone: +17% in 3 Months [Meta-Analysis 2018]

Ginger and Testosterone: +17.7% Documented in Meta-Analysis

Clinical summary: Banihani's (2018) systematic review compiling human and animal studies reports an average testosterone increase of 17.7% after 3 months of ginger supplementation. Main mechanism: antioxidant protection of Leydig cells + increased LH.

Ginger and testosterone: the evidence

Banihani 2018 Study (Systematic Review)

Compilation of all available studies on ginger and male hormones:

  • Average increase in serum testosterone: +17.7%
  • Increase in LH (luteinizing hormone): +43.2%
  • Improvement in sperm concentration: +16.2%
  • Improvement in sperm motility: +47.3%

Mares & Najam 2012 Study (Human Clinical Trial)

75 infertile men, 3 months of ginger supplementation:

  • Serum testosterone: significant increase (p < 0.01)
  • FSH and LH: increased
  • Sperm volume and motility: improved

Mechanisms of action on testosterone

1. Antioxidant protection of Leydig cells

Leydig cells (testosterone-producing cells in the testes) are extremely sensitive to oxidative stress. 6-gingerol neutralizes ROS (reactive oxygen species) that damage these cells → sustained testosterone production.

2. Increase in LH

Ginger stimulates the hypothalamic-pituitary-gonadal axis → increased LH secretion by the pituitary gland → reinforced signal to Leydig cells to produce more testosterone.

3. Reduction of testicular oxidative stress

Activation of the Nrf2 pathway → increased production of glutathione, SOD, and catalase at the testicular level → favorable environment for spermatogenesis and steroidogenesis.

4. Testicular anti-inflammation

Inhibition of NF-κB → reduction of TNF-α and IL-6 at the testicular level → less inflammatory damage to germ cells and Leydig cells.

Sugar: testosterone's number 1 enemy

Caronia et al. (2012, Journal of Clinical Endocrinology & Metabolism) study: 75g of glucose reduce testosterone by 25% for 2 hours in healthy men.

A ginger shot with 33g of sugar/100ml contains ~8g of simple sugars. This is the paradox: you take ginger for testosterone, but the sugar in the shot makes it drop.

Frequently asked questions

Does ginger really increase testosterone?

Yes. Banihani's (2018) systematic review reports an average increase of 17.7% in serum testosterone after 3 months of supplementation. The main mechanism is the antioxidant protection of Leydig cells (testosterone-producing cells) via 6-gingerol. INTI provides the effective dose of organic ginger without the sugar which, according to Caronia 2012, reduces testosterone by 25% for 2 hours.

How much ginger to increase testosterone?

Clinical studies use 1-2g of ginger per day for a minimum of 3 months. Regularity is crucial — effects on testosterone and spermatogenesis require prolonged daily intake. A daily INTI shot provides the dose in a convenient format and without added sugar.

Does sugar in ginger shots cancel out the effect on testosterone?

Partially, yes. The Caronia (2012, JCEM) study shows that 75g of glucose reduce testosterone by 25% for 2 hours. A shot containing 33g of sugar/100ml provides ~8g of simple sugars — enough to counteract part of ginger's pro-testosterone effect. INTI contains 1.1g of sugar/100ml, which preserves the hormonal effect of ginger.

⚠️ Ginger does not replace prescribed hormone therapy. If hypogonadism is suspected, consult an endocrinologist for a complete hormonal evaluation.
