Summary
Hen's egg yolk significantly boosts human sperm motility, increasing it from 66.2% to 87.2%. This suggests egg yolk possesses sperm motility stimulating properties for potential therapeutic use.
Area of Science:
- Reproductive Biology
- Andrology
- Biochemistry
Background:
- Human sperm motility is crucial for natural fertility.
- Suboptimal sperm motility, such as in asthenospermia, can impair fertility.
- Identifying natural compounds that enhance sperm function is of significant interest.
Purpose of the Study:
- To investigate the effect of 20% hen's egg yolk medium on human sperm motility.
- To determine if hen's egg yolk can improve the percentage of motile sperm.
Main Methods:
- Human semen samples (n=21) with high sperm density and motility were used.
- Semen was divided into control and experimental groups.
- Experimental group sperm was processed through a 20% hen's egg yolk column in Tyrode's solution; motility was assessed hourly.
Main Results:
- Sperm motility increased from 66.2% to 87.2% after passage through hen's egg yolk.
- Control group motility declined to 49.3% over the same period.
- After 5 hours, experimental group motility averaged 80% compared to 17.4% in the control.
Conclusions:
- Hen's egg yolk demonstrates a significant sperm motility stimulating property.
- Further research is warranted to explore hen's egg yolk as a potential treatment for asthenospermia and oligospermia.
