Patients with GBM and altered sex hormone states could offer insight into a relationship between the two. Most GBMs arise sporadically and heritable genetic influence on GBM development is poorly understood, but reports describing familial GBM suggest genetic predispositions exist. However, no existing reports examine GBM development in context of both supraphysiologic sex hormone states and familial predisposition for GBM. We present a case of isocitrate dehydrogenase (IDH)-wild type GBM in a young pregnant female with polycystic ovary syndrome (PCOS), history of<jats:italic>in vitro<\/jats:italic>fertilization (IVF), and significant family history of GBM and further discuss how unique sex hormone states and genetics may affect GBM development or progression.<\/jats:p><\/jats:sec><jats:sec id=\"st2\"><jats:title>Case Description:<\/jats:title><jats:p>A 35-year-old pregnant female with PCOS and recent history of IVF treatment and frozen embryo transfer presented with seizure and headache. Imaging revealed a right frontal brain mass. Molecular and histopathological analysis of the resected tumor supported a diagnosis of IDH-wild type GBM. The patient\u2019s family medical history was significant for GBM. Current literature indicates testosterone promotes GBM cell proliferation, while estrogen and progesterone effects vary with receptor subtype and hormone concentration, respectively.<\/jats:p><\/jats:sec><jats:sec id=\"st3\"><jats:title>Conclusion:<\/jats:title><jats:p>Sex hormones and genetics likely exert influence on GBM development and progression that may compound with concurrence. Here, we describe a unique case of GBM in a young pregnant patient with a family history of glioma and atypical sex hormone exposure due to endocrine disorder and pregnancy assisted by exogenous IVF

administration.<\/jats:p><\/jats:sec>","DOI":"10.25259\/sni_58_2023","type":"journal-article","created":{"date-parts":[[2023,5,12]],"date-time":"2023-05-12T06:51:06Z","timestamp":1683874266000},"page":"169","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Glioblastoma
