The articles investigate the effects of PYY administration on the reproductive axis in healthy young men and effects of GLP-1 administration on the reproductive axis in humans. The study took place at the Clinical Research Facility, Imperial College Healthcare NHS Trust with eighteen healthy men. Yoshibye has almost two years of experience in healthcare market research, having joined our graduate training scheme in September 2018. She graduated from the University of Nottingham with a BSc in Neuroscience and has also completed an MRes in Clinical Research in Diabetes and Obesity. Commenting on the papers, Yoshibye says, “These studies investigated the effects of gut hormones on reproductive hormones. Although the results were negative, they were the first of its kind to be carried out and gave direction into the kind of research we need to conduct moving forward. Research in this area will help with the understanding of the links between reproduction and metabolism, especially with the growing prevalence of eating disorders and obesity.” The papers were published in this month’s edition of the Journal of Clinical Endocrinology & Metabolism and can also be found on the Oxford Academic website below:  [https://academic.oup.com/jcem/article/105/3/dgz103/5599746 https://academic.oup.com/jcem/advance-article/doi/10.1210/clinem/dgaa072/5735220](https://academic.oup.com/jcem/advance-article/doi/10.1210/clinem/dgaa072/5735220%20) ![Research Partnership](https://adv.researchpartnership.com/hubfs/Social-media-LogosLinkedIn_Twitter_ColRev-1.png) ### [Research Partnership](https://adv.researchpartnership.com/news/author/research-partnership) All the latest news from Research Partnership ### Get our newsletter direct to your inbox. ## Sign up to receive Rapport Rapport is our monthly newsletter where we share our latest expertise and experience.   [![Sign up here](https://no-cache.hubspot.com/cta/default/5339817/e22f960a-4cee-4787-827e-b840704d3075.png)](https://cta-redirect.hubspot.com/cta/redirect/5339817/e22f960a-4cee-4787-827e-b840704d3075) -
