Sperm tail axoneme alterations in the Wobbler mouse
Journal of Reproduction and Fertility
|January 1, 1980
Summary
Wobbler mice with motor neuron disease show sperm tail defects and abnormal axoneme geometry. These abnormalities also affect the ciliary axonemes in the ductuli efferentes, impacting sperm motility and reproductive health.
Area of Science:
- Neuroscience
- Reproductive Biology
- Cell Biology
Background:
- Wobbler mice are a model for progressive motor neurone degenerative disease.
- Sperm tail and ciliary axonemes are crucial for motility and reproductive function.
Purpose of the Study:
- To investigate sperm tail and ciliary axoneme abnormalities in Wobbler mice.
- To understand the impact of neurological mutations on sperm and ciliary structure.
Main Methods:
- Microscopic examination of sperm tails from Wobbler mice.
- Analysis of axonemal geometry and structure in sperm and ciliary cilia.
Main Results:
- Significant defects in sperm tail mobility and axonemal geometry were observed in Wobbler mice.
- Less severe abnormalities were found in the ciliary axonemes of the ductuli efferentes.
Conclusions:
- Neurological mutations in Wobbler mice lead to structural defects in sperm and cilia.
- These axonemal abnormalities may contribute to impaired sperm function and reproductive issues.
