#19 Female hormones and the immune system, with Abigail Goodship

Analysis of wearable data gathered from the Visible app found that symptoms in Long Covid and ME/CFS fluctuated considerably in-line with the menstrual cycle, in a new study from Imperial College (currently in pre-print).

In this week’s episode Abigail Goodship, a biomedical scientist at Imperial College, responsible for scrutinizing the data from almost 4000 women, talks us through the findings of the study, which corroborates something which women have been anecdotally reporting for years, and gives us insights into how we might be able to manipulate hormones and work with our cycles to live a more balanced illness.

The points at which the immune and endocrine systems interact are complex and multi-layered with the hypothalamus, pituitary glands and ovaries all playing different roles in the functioning of our cycles. Emily Kate Stephens and Abigail take it back to basics, discussing the hormones involved and the way in which they shape the menstrual cycle, before diving into what the research teaches us about symptom variability which tends to worsen in the pre-menstrual phase and improve around ovulation. Understanding the hormones at play at these points, and the impact they have on our immune systems, inflammation levels and pain perception will be key to using this information to develop helpful strategies and potential treatments.

We discuss the potential implications of pregnancy, vaccination, contraception, menopause and HRT in Long Covid and ME/CFS, along with the role of hormones in autoimmune conditions, as areas that are ripe for more substantial research in this much under-researched area of menstrual health.

Abigail Goodship is a first year PhD student in the Department of Metabolism, Digestion and Reproduction at Imperial College London. Under the supervision of Dr Viki Male and Dr Bryn Owen, Abigail is researching the fascinating intersection of immunology and reproductive endocrinology, with a focus on how the immune system influences the menstrual cycle. Her work combines laboratory techniques like cytokine assays and hormone profiling with big data analysis, aiming to better understand menstrual changes after vaccination and the impact of chronic immune dysregulation on reproductive health. Drawing on expertise across both biological and computational sciences, Abigail is dedicated to bridging disciplines to advance women’s health, with a focus on translating research into meaningful, real-world impact. Her work is funded by the Medical Research Council (grant number MR/W00710X/1).
