The gonadotrophin-releasing hormone (GnRH) system in female Damaraland mole-rats, Cryptomys damarensis, has been investigated to map the distribution of GnRH-immunoreactive (GnRH-IR) structures ... Breeding is limited to a single reproductive pair in colonies that may contain as many as 41 individuals (Jarvis & Bennett 1993).

The gonadotrophin-releasing hormone (GnRH) system in female Damaraland mole-rats, Cryptomys damarensis, has been investigated to map the distribution of GnRH-immunoreactive (GnRH-IR) structures in the brain of this species and to assess whether changes in this system may mediate the inhibitory effect of social cues...

The size and number of cells within Onuf's nucleus (homologue of the rat spinal nucleus of the bulbocavernosus) as well as perineal muscle volume were examined in subordinate and breeding naked mole-rats of both sexes.
