Rams DO use their brains for reproduction

Charles Sturt University (CSU) PhD graduate Dr Jessica Rose examined the potential of two recently discovered hormones in the brain that are involved in reproduction in merino rams.

Dr Jessica Rose“My research focused on two hormones called kisspeptin and RF-amide related peptide 3 (RFRP-3),” Dr Rose said.

“Brain mapping studies and whole animal studies provided evidence that cells which make kisspeptin are most likely involved in controlling reproduction, and that the presence of testicles affects these cell numbers in the brain, but there is less evidence for RFRP-3 having a role in reproduction in the ram.”

Dr Rose’s research increases understanding of the brain control of reproduction in males.

Her research was funded by a CSU Faculty of Science (COMPACT) Scholarship and she is one of 11 Graham Centre PhD students who graduated on Tuesday 12 December 2017.
