This study highlights the spermicidal effects of anions, finding that halides primarily exhibit spermicidal activity, while sulfates and nitrates are mostly spermiostatic. Specific compounds like copper sulfate and silver nitrate showed spermicidal action at higher concentrations.

Area of Science:

Inorganic Chemistry
Reproductive Toxicology
Pharmacology

Background:

Metallic ions are often spermicidal.
The role of anions in sperm motility requires further investigation.

Purpose of the Study:

To investigate the spermicidal and spermiostatic activities of various inorganic anions.
To determine the concentration-dependent effects of these anions on sperm viability.

Main Methods:

Screening of inorganic compounds at four concentrations: 0.01%, 0.1%, 1%, and 5%.
Evaluation of the effects of halides, sulfates, and nitrates on sperm motility and viability.

Main Results:

Halides generally demonstrated spermicidal activity, with exceptions like NaCl, KCl, and CsCl showing spermiostatic effects.

Sulfates and nitrates were predominantly spermiostatic, except for zinc sulfate (ZnSO4) at 1% and above.

Copper sulfate (CuSO4), aluminum sulfate (Al2(SO4)3), uranyl nitrate (Uo2(NO3)2·6H2O), and silver nitrate (AgNO3) exhibited spermicidal activity at a 5% concentration.

Conclusions:

Anions play a significant role in modulating sperm viability.
Specific inorganic anions possess concentration-dependent spermicidal or spermiostatic properties.
