Published:

Visiting Speaker Tobin Magle provided a super lecture introducing attendees to reproducible research concepts and workflow. Materials and links were provided helping people get started. If interested in access to RRC materials (via invitation to the Club GitHub repository), including RStudio templates, email Josh at joshua.2.johnson@ucdenver.edu. We’ll hold RRC biweekly, offering statistics and data management “clinic time” at each meeting.

A ‘general research interests’ talk for the UC-Denver Integrated Physiology Graduate Program, with focus on our work on Fragile X Premutation. I will cover recent progress in studying basic follicle development and survival, challenges in quantifying ovarian follicles, and the interface between reproductive physiology and reproductive medicine.

Controlling the Rate of Primordial Ovarian Follicle Growth Activation

Published:

Designed an accepted Minisymposium on this topic for the 2019 Paris Society for Reproductive Investigation Meeting (Paris, France).

Dr. Kathleen Connell, Division Director of the Division of Urogynecology and Pelvic Floor Reconstructive Surgery, presented these data on behalf of co-authors Johnson, J., Guess, M.K., Rascoff, L., Orlicky, D., Bales, E.S., Arruda, J., Kumar, R. This lecture is included because this collaborative abstract was awarded the best basic science abstract and presented in the plenary opening session at the AUGS/IUGA Joint Scientific Meeting.

Ovarian Recovery in Cancer Survivorship. Keynote Lecture

Published:

This lecture for a fertility preservation provider audience provided a backdrop of basic and translational ovarian biology. In it, we asked the question: when we cryopreserve patient ovarian cortex, what is it that needs to “go right” so ovarian function recovers? So that the patient has the highest chances for ongoing ovarian function and potential conception? Special consideration was given to potentially compromised ovarian function due to the underlying cancer.
