Summary
Trace elements like selenium (Se) are crucial for male fertility, significantly correlating with sperm concentration. Zinc (Zn) levels in semen did not directly correlate with sperm parameters but showed relationships with other elements.
Area of Science:
- Reproductive Biology
- Environmental Health
- Human Physiology
Context:
- Trace elements play a vital role in human reproductive health.
- Previous research highlighted zinc's importance in male sexual function.
- Limited information exists regarding trace elements in female reproductive function.
Purpose:
- To summarize existing literature on trace elements and male reproductive potential.
- To present data on 13 elements in semen samples from infertile males.
- To investigate correlations between specific elements and sperm parameters.
Summary:
- Semen analysis revealed element concentrations in the order Na > P, K > Ca > Zn > Mg > Fe > Cu > Se >> Sn, Ni, Co, Cd.
- A significant positive correlation was found between selenium (Se) concentration and sperm concentration (r = 0.589, p < 0.001), with higher correlation in spermatozoa (r = 0.886).
- Zinc (Zn) in semen did not correlate with sperm parameters but was correlated with magnesium (Mg), potassium (K), and calcium (Ca) concentrations.
Impact:
- Highlights the critical role of selenium in male fertility and sperm quality.
- Provides baseline data on trace element levels in infertile males.
- Suggests potential interactions between different trace elements influencing male reproductive health.
