Plant Extracts as Alternative Additives for Sperm Preservation

Area of Science:

• Reproductive Biology
• Phytochemistry
• Animal Science

Background:

• Sperm preservation is vital for assisted reproductive technology (ART) success in humans, livestock, and wildlife.
• Semen handling and storage negatively impact sperm quality, often exacerbated by oxidative stress.
• Oxidative stress damages sperm components, reducing fertilizing capacity.

Purpose of the Study:

• To review the use of plant extracts as natural additives for improving sperm preservation and function.
• To update knowledge on plant-based additives for semen storage across 13 species, including humans.
• To detail the effects of 45 plant species on sperm quality during storage.

Main Methods:

• Literature review of studies investigating plant extracts for sperm preservation.
• Analysis of data on 45 plant species from 28 families.
• Inclusion of details on plant material, extraction methods, dosage, toxicity, and antimicrobial properties.

Main Results:

• Plant extracts show potential as cost-effective, natural additives to counteract negative effects of semen storage.
• Specific plant species and their properties influencing sperm function during preservation are identified.
• Information on dosage, potential toxicity, and antimicrobial activity of plant extracts is compiled.

Conclusions:

• Plant extracts represent a promising alternative for enhancing sperm preservation and function in ART.
• Further research into specific plant compounds could optimize their application in semen extenders.
• Natural additives offer a sustainable approach to improve reproductive outcomes in diverse species.
