Elevated levels of LRH in human milk
The Journal of Clinical Endocrinology and Metabolism
|April 1, 1981
Summary
Luteinizing hormone-releasing hormone (LHRH) is five to six times more concentrated in human breast milk than in maternal blood plasma. These elevated LHRH levels in milk may significantly impact infant development.
Area of Science:
- Endocrinology
- Neonatal Biology
- Reproductive Medicine
Background:
- Human milk contains various bioactive molecules crucial for infant development.
- Hormone concentrations can differ significantly between maternal circulation and breast milk.
- Understanding neonatal exposure to milk-borne hormones is vital for assessing developmental influences.
Purpose of the Study:
- To quantify and compare Luteinizing Hormone-Releasing Hormone (LHRH) levels in human milk and maternal plasma.
- To investigate the potential implications of high LHRH concentrations in breast milk on neonatal development.
Main Methods:
- Utilized a double antibody radioimmunoassay technique for precise hormone quantification.
- Collected paired samples of human milk and maternal plasma from lactating women.
Main Results:
- LHRH levels in human milk were found to be 5-6 times higher than in concurrent maternal plasma samples.
- Demonstrated a significant enrichment of LHRH in breast milk compared to systemic circulation.
Conclusions:
- Maternal milk serves as a concentrated source of LHRH for neonates.
- Elevated LHRH in breast milk may play a critical role in the development of neonatal reproductive and related biological systems.
- Further research is warranted to elucidate the precise mechanisms and long-term effects of this hormonal exposure.
