The Claim
Human spermatozoa with higher cholesterol and desmosterol content exhibit reduced membrane fluidity during capacitation, which is associated with impaired protein tyrosine phosphorylation and decreased hyperactivation, suggesting that abnormal lipid composition may underlie functional deficiencies in sperm capacitation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Sperm cells with too much cholesterol and a similar fat called desmosterol don't move as well when they're getting ready to fertilize an egg, and this might be because those fats mess with their internal signaling system.

What the research says
1 studySperm with too much cholesterol and a similar fat molecule don’t become as flexible as they should when trying to fertilize an egg, which stops them from activating properly. This means their bad lipid makeup might be why some sperm can’t do their job.
