Effect of cyproterone acetate on the testis and epididymis of the lizard, Psammophilus dorsalis (gray). 1980

G R Shivakumar, and H B Sarkar

The effect of cytproterone acetate (CPA) on the testis and epididymis of the lizard, Psammophilus dorsalis has been studied. Treatment with CPA affects spermatogensis and steroid metabolism in the testis. It also causes regression of the epididymis and a decrease in steroidogenic enzyme activity.

UI	MeSH Term	Description	Entries
D008116	Lizards	Reptiles within the order Squamata that generally possess limbs, moveable EYELIDS, and EXTERNAL EAR openings, although there are some species which lack one or more of these structures.	Chameleons,Geckos,Chameleon,Gecko,Lizard
D008297	Male		Males
D003534	Cyproterone	An anti-androgen that, in the form of its acetate (CYPROTERONE ACETATE), also has progestational properties. It is used in the treatment of hypersexuality in males, as a palliative in prostatic carcinoma, and, in combination with estrogen, for the therapy of severe acne and hirsutism in females.	Cyproterone, 1alpha,2 alpha,9 beta,10 alpha-Isomer
D004822	Epididymis	The convoluted cordlike structure attached to the posterior of the TESTIS. Epididymis consists of the head (caput), the body (corpus), and the tail (cauda). A network of ducts leaving the testis joins into a common epididymal tubule proper which provides the transport, storage, and maturation of SPERMATOZOA.
D006651	Histocytochemistry	Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods.	Cytochemistry
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D013091	Spermatogenesis	The process of germ cell development in the male from the primordial germ cells, through SPERMATOGONIA; SPERMATOCYTES; SPERMATIDS; to the mature haploid SPERMATOZOA.	Spermatocytogenesis,Spermiogenesis
D013737	Testis	The male gonad containing two functional parts: the SEMINIFEROUS TUBULES for the production and transport of male germ cells (SPERMATOGENESIS) and the interstitial compartment containing LEYDIG CELLS that produce ANDROGENS.	Testicles,Testes,Testicle
D015067	17-Hydroxysteroid Dehydrogenases	A class of enzymes that catalyzes the oxidation of 17-hydroxysteroids to 17-ketosteroids.
