The Claim
In ovariectomized ewes, endotoxin administration suppresses luteinizing hormone pulse frequency (P = 0.01), reduces luteinizing hormone pulse amplitude (P < 0.05), and lowers mean luteinizing hormone concentrations (P = 0.001), indicating a broad suppression of pituitary gonadotropin output.
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.
In sheep without ovaries, endotoxin reduces the frequency and size of luteinizing hormone pulses and lowers overall luteinizing hormone levels in the blood, indicating decreased output from the pituitary gland.
See the scientific wording
In ovariectomized ewes, endotoxin suppresses luteinizing hormone (LH) pulse frequency (P = 0.01) and amplitude (P < 0.05), in addition to reducing mean LH concentrations (P = 0.001), indicating a broad suppression of pituitary gonadotropin output.
A bacterial toxin enters the bloodstream and signals the brain to stop sending regular bursts of a hormone that tells the pituitary to release LH. Without these bursts, the pituitary releases less LH overall, with fewer pulses and smaller pulse sizes.
What the research says
1 studyIn sheep without ovaries, a bacterial toxin called endotoxin made the brain send fewer and weaker signals to the pituitary gland, which in turn released less of the reproductive hormone LH. This matches exactly what the claim says.
