Sexual behavior attenuates the effects of chronic stress in body weight, testes, sexual accessory glands, and plasma testosterone in male rats.
The aim of this study was to evaluate whether continuous sexual behavior could attenuate the effects of chronic stress on spermatogenesis, sexual glands, plasma testosterone and corticosterone in sexually experienced male rats. Rats were exposed to stress by immersion in cold water (ICW) daily for 20 or 50 consecutive days. Plasma testosterone and corticosterone, masculine sexual behavior, as w...

Tolnidamine-Induced Changes in the Testis, Sperm Count, Fertility and Accessory Sex Glands of the Laboratory Mouse
Background Tolnidamine-induced changes have been reported earlier on spermatogenesis, fertility and sperm count in rat, rabbit and langur monkey. The aim of this study is to assess the response of these aspects to tolnidamine in the laboratory mouse. MaterialsAndMethods Adult male mice (12-14 weeks old) of Parkes (P) strain were used in the present study. All the animals were divided into five ...
متن کاملTranscriptional Profiles of Mating-Responsive Genes from Testes and Male Accessory Glands of the Mediterranean Fruit Fly, Ceratitis capitata
BACKGROUND Insect seminal fluid is a complex mixture of proteins, carbohydrates and lipids, produced in the male reproductive tract. This seminal fluid is transferred together with the spermatozoa during mating and induces post-mating changes in the female. Molecular characterization of seminal fluid proteins in the Mediterranean fruit fly, Ceratitis capitata, is limited, although studies sugge...
متن کاملDemonstration of porcine circovirus type 2 in the testes and accessory sex glands of a boar
Porcine circovirus type 2 (PCV2) antigen was demonstrated in lungs, lymphoid tissues, intestines, and testes and accessory sex glands of an 11-month-old boar from a boar stud with a history of recent illness and infertility. At necropsy, the lungs failed to collapse and there was moderate cranioventral bronchopneumonia. Microscopically, there was severe multifocal suppurative and histiocytic br...
