Infertility affects 1 in 6 couples in Western countries. Oxidative stress is involved in 30-80% of male infertility cases (Agarwal et al., Reproductive Biology and Endocrinology, 2003). Ginger and turmeric are among the most studied natural antioxidants in reproductive medicine.
Ginger and sperm quality
Mares & Najam (Tikrit Medical Journal, 2012) studied 75 infertile men receiving 250 mg of ginger 3×/day for 3 months:
| Parameter | Before | After 3 months | Improvement |
|---|---|---|---|
| Sperm motility | 42% | 58% | +16 points |
| Sperm volume | 2.1 ml | 2.8 ml | +33% |
| Concentration | 18 M/ml | 26 M/ml | +44% |
| Normal morphology | 8% | 14% | +75% |
Curcumin and ovarian protection
Curcumin protects oocytes from oxidative stress by activating the Nrf2/ARE pathway (Yan et al., Molecular Human Reproduction, 2018). It also reduces inflammation in polycystic ovary syndrome (PCOS), the leading cause of female infertility.
Sugar: an enemy of fertility
Chiu et al. (Epidemiology, 2018) showed that sugary drink consumption reduces fecundability by 20% in women and 33% in men. The mechanism: insulin resistance → disruption of sex hormones → ovulatory dysfunction and impaired spermatogenesis.

FAQ
Does ginger increase male fertility?
Yes. Mares & Najam (2012) showed a significant improvement in sperm motility (+16 points), volume (+33%), and concentration (+44%) after 3 months of ginger supplementation.
Does turmeric help with PCOS?
Curcumin reduces inflammation and insulin resistance in PCOS (Heshmati et al., 2021). It is not a first-line treatment but a promising supplement.
