Subject: Re: [AUDITORY] Sex differences in auditory processing From: Didier Depireux <depireux@xxxxxxxx> Date: Wed, 12 Jan 2022 16:23:06 -0500--000000000000c4794805d5692db4 Content-Type: multipart/alternative; boundary="000000000000c4794605d5692db3" --000000000000c4794605d5692db3 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable A few papers were recently published by Ronna Hertzano's labs, including 1) Sex differences in hearing: Probing the role of estrogen signaling <https://pubmed.ncbi.nlm.nih.gov/31255106/> (a review) 2) The impact of biological sex on the response to noise and otoprotective therapies against acoustic injury in mice <https://pubmed.ncbi.nlm.nih.gov/29530094/> 3) Estradiol Protects against Noise-Induced Hearing Loss and Modulates Auditory Physiology in Female Mice <https://pubmed.ncbi.nlm.nih.gov/34830090/> Glad to answer questions you might have. 17=CE=B2-estradiol (E2) is a known modulator of auditory physiology, and I = don't think there is evolutionary pressure to have hearing fluctuate over the hormonal cycle. I *think *hearing (and resilience to hearing loss) dimorphism might be at least in part a by-product of the available hormones and receptors across sexes and genders.
