Title Modification of Mammalian Sexual Cycles Type Journal Article
Year (up) 1935 Publication Journal of Experimental Biology Abbreviated Journal
Volume 12 Issue Pages 315-320
Keywords Animals
Abstract 1. Cases are given in which female ferrets, already coming into, or in, oestrus as the result of artificially increased lighting in winter and spring, underwent regression or were retarded in their activation by reduction of either intensity or duration of daily illumination.

2. In some cases activation was resumed when light time or intensity was increased again.

3. These results are taken to indicate that, in female ferrets, any inherent rhythm or cycle of sexual activity is modified either naturally or artificially by changes of the cycles of duration and intensity of the light to which they are exposed daily, and so made to correspond in phases with the seasons, or changed therefrom. The rising daily illumination in spring and the falling one in late summer and autumn probably accelerate and retard the sexual activity of the female ferret, or accelerate the onset of anoestrus in late summer and autumn.

4. The data on modification of sexual cycles or activity in ferrets, so far obtained, are consistent with these conclusions.

Title Modification of mammalian sexual cycles. V. The avenue of reception of sexually stimulating light Type Journal Article
Year (up) 1936 Publication Journal of Comparative Psychology Abbreviated Journal Journal of Comparative Psychology
Volume 22 Issue 1 Pages 93-103
Keywords Animals
Abstract The author subjected female ferrets of controlled previous light and sexual history to added nightly lighting (1) without hoods, (2) with hoods which exposed the eyes through holes, and (3) with heads covered by light-tight hoods. The conditions of decreased light on the eyes were associated with delayed oestrus. “The facts indicate that the eyes are the receptors for photo-periodic sexual stimulation in ferrets, mediated by the anterior hypophysis, and that closing their eyes in sleep does not prevent the activation.”
