Blocking hormone could eliminate stress-induced infertility

Stress is known to interfere with reproduction, but a new study shows that the effects of chronic stress on fertility persist long after the stress is gone.

In rats, they successfully blocked the hormone gene and restored normal reproductive behavior, suggesting therapeutic potential for stressed humans and animals in captive breeding programs.
