The distribution of immunoreactive GnRH-like substances in various tissues of the lizard (Podarcis s. sicula) in relation to different phases of the sexual cycle are described. GnRH-like substances in the hypothalamic extracts decrease during the reproductive period. In the extrahypothalamic tissue, the levels of immunoreactive GnRH-like substances are highest in early spring and summer, and decrease in autumn, winter and late spring. In the other tissues (gonads, liver and small intestine), a more constant immunoreactivity has been observed. All tissue extracts stimulate the release of luteininzing hormone (LH) from chicken anterior pituitary cells. In testis this phenomenon is more evident in early spring and summer; in the other tissues, two peaks of activity can be detected, in spring and in autumn. These findings suggest that GnRH-like substances could be involved in the regulation of various aspects of reproductive processes in the lacertid Podarcis s. sicula Raf.
