It is estimated that about 40% of cases in couples not being able to conceive is due to infertility in men. These group of researchers found that zinc deficiency is common and contribute to poor sperm health.
Eleven volunteers were given zinc supplement (and zinc from their diet) ranging from 1.4 to 10.4 mg daily for 35 days.

Those taking only 1.4 mg of zinc daily had less semen volume (2.24 mL) compared to those taking 10.4 mg of zinc (who had 3.30 mL).

Moreover, taking 10.4 mg of zinc resulted in higher blood concentration of testosterone; 26.9 nmol/L versus 21.9 nmol/L in those taking just 1.4 mg of zinc.

The conclusion from this study is that a deficiency in zinc not only reduces the amount of semen per ejaculation, it also lowers testosterone levels, essential for maintaining sex drive.

"The conclusion from this study is that a deficiency in zinc not only reduces the amount of semen per ejaculation, it also lowers testosterone levels, essential for maintaining sex drive. "

Va i helvete, fattar ingenting? Först sägs de att de som intog 10.4 hade större testosterone värde 26.9 än de andra som hade 21.9 som endast intog 1.4 mg, sen i slutet skriver man den skiten att zinc lowers testosterone levels? Kan någon förklara.

Vet att jag märker mig bli betydligt kåtare när jag käkar zinkrik föda så som hårt bröd.

Citat:Zinc and selenium are essential minerals and have roles for more than 300 metabolic reactions in the body. The purpose of this study was to investigate how exhaustive exercise affects testosterone levels and plasma lactate in cyclists who were supplemented with oral zinc and selenium for 4 weeks. For this reason, 32 male road cyclists were selected equally to four groups: PL group, placebo; Zn group, zinc supplement (30 mg/day); Se group, selenium supplement (200 μg/day); and Zn-Se group, zinc-selenium supplement. After treatment, free, total testosterone, and lactate levels of subjects were determined before and after exhaustive exercise. Resting total, free testosterone, and lactate levels did not differ significantly between groups, and were increased by exercise (P > 0.05). Serum total testosterone levels in Zn group were higher than in Se group after exercise (P < 0.05). Serum-free testosterone levels in the Zn group were higher than the other groups (P < 0.05).There was an insignificant difference between levels of lactate in the four groups after exercise (P > 0.05). The results showed that 4-week simultaneous and separately zinc and selenium supplementation had no significant effect on resting testosterone and lactate levels of subjects who consume a zinc and selenium sufficient diet. It might be possible that the effect of zinc supplementation on free testosterone depends on exercise.
