Gonadotropin-releasing hormone

Otago researchers have discovered that neural circuitry they previously showed was vital to triggering ovulation and maintaining fertility also plays a key role in moulding the male brain.

In new research appearing in the Journal of Neuroscience, a team led by Professor Allan Herbison shows that male-specific signalling in the Gonadotropin-releasing hormone (GnRH) neurons of new-born mice is crucial to generating a testosterone surge that occurs up to five hours after birth.
