D. Mcfadden et al., CHANGES IN OTOACOUSTIC EMISSIONS IN A TRANSSEXUAL MALE DURING TREATMENT WITH ESTROGEN, The Journal of the Acoustical Society of America, 104(3), 1998, pp. 1555-1558
Otoacoustic emissions (OAEs) were monitored in two human males undergo
ing estrogen treatment prior to sex-reversal surgery. In one subject,
multiple spontaneous emissions (SOAEs) appeared where none had been ev
ident previously. One reasonable interpretation is that (in this male,
at least) androgens normally produced a suppressive effect on the coc
hlear mechanisms responsible for SOAEs, and that the decline in androg
en levels produced by the estrogenic drug led to a reduction in that s
uppression. (C) 1998 Acoustical Society of America. [S0001-4966(98)032
