Panax ginseng induces the expression of CatSper genes and sperm hyperactivation

Area of Science:

• Reproductive Biology
• Molecular Biology
• Pharmacology

Background:

• The cation channel of sperm (CatSper) protein family is crucial for male reproduction and fertility.
• CatSper proteins are exclusively expressed in the testis and have distinct localizations within sperm.

Purpose of the Study:

• To investigate the impact of Panax ginseng on CatSper gene expression and sperm hyperactivation in male mice.
• To assess the effects of P. ginseng on sperm motility and intracellular calcium levels.

Main Methods:

• Computer-assisted semen analysis for sperm motility.
• Fluorometry to measure Ca²⁺ influx.
• Real-time PCR and Western blotting for gene and protein expression analysis.
• Immunofluorescence for protein localization.

Main Results:

• Panax ginseng treatment significantly increased Ca²⁺ levels in sperm cells.
• P. ginseng improved sperm motility parameters, including curvilinear velocity and amplitude of lateral head displacement.
• CatSper messenger RNA and protein levels were elevated in P. ginseng-treated mouse testes, except for CatSper2.

Conclusions:

• Panax ginseng significantly enhances sperm hyperactivation.
• The herb improves male fertility by modulating CatSper gene expression and function.
• P. ginseng represents a potential therapeutic agent for male infertility.
