Indian Researchers Reveal Chronic Stress Damages Male Fertility
Two scientists in India found out how long-term stress can hurt men's ability to make sperm.
They did experiments on rats and discovered that stress weakens a protective barrier in the testicles over time.
This barrier usually keeps harmful things from hurting the sperm.
When it gets weak, the sperm doesn't grow properly.
The scientists also found that a hormone called irisin might play a role in this process.
This research helps us understand how stress can cause problems with making babies and might lead to new treatments in the future.
Indian researchers found that chronic stress weakens the blood-testis barrier, affecting sperm production.
The study used rats exposed to various stressors for 8, 14, and 18 weeks.
Chronic stress inactivates key proteins in the blood-testis barrier, leading to reduced sperm count, motility, and DNA integrity.
The researchers identified irisin, a hormone in testicular tissue, as a potential therapeutic target for stress-related infertility.
The findings were published in the journal Reproductive Sciences and provide mechanistic insights into how chronic stress impacts male fertility.
