Washington, June 16: Researchers from University of California, Berkeley claim to have found a missing piece of puzzle about how stress causes sexual dysfunction and infertility.
The study showed that stress delivers a double whammy on reproductive system and fertility.
It is already known that stress boosts levels of stress hormones - glucocorticoids such as cortisol - that inhibit the body’s main sex hormone, gonadotropin releasing hormone (GnRH), and subsequently suppresses sperm count, ovulation and sexual activity.
However, the new study showed that stress also increases brain levels of a reproductive hormone named gonadotropin-inhibitory hormone, or GnIH, discovered nine years ago in birds and known to be present in humans and other mammals.
