O-14: Effect of Kisspeptin on Testicular Tissue and Accessory Sex Glands, Seminal Vesicle and Prostate, in Prepubertal Rats
Background: Hypothalamus-derived kisspeptins are critical regulators of reproduction in nearly all mammalian species including the humans. These small peptides mediate their actions through the GnRH loop system. How kisspeptins regulate gonadal maturation in sexually immature male mammals remains elusive. To address this, kisspeptin was administered as subchronic (12 days) twice daily i. p. dos...
متن کاملTolnidamine-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 کاملPrepubertal and Pubertal Gynecomastia
Physiology and molecular mechanisms Gynecomastia is defined as the growth of the male mammary gland to become palpable and/or visible. During embryogenesis, the differentiation of the mammary gland and surrounding estroma, as well as the areola and the nipple, is similar in the two sexes. It is well established that estrogens stimulate breast growth. The production of estrogens during pregnancy...
متن کاملAccessory sex glands as a tool to measure the efficacy of immunocastration in male pigs.
The use of an anti-gonadotropin-releasing hormone vaccine for immunocastration of male pigs has been recently approved in the European Union. This technique is potentially useful for avoiding both castration-associated pain for the animal and boar taint in pork. However, some animals may escape immunocastration and be slaughtered as entire males, potentially exhibiting boar taint. Therefore, it...
متن کاملThe accessory sex glands as the repository for juvenile hormone in male cecropia moths.
Gas chromatographic determinations, bioassays, and radio-labelling experiments show that the juvenile hormone in adult male Hyalophora cecropia is accumulated exclusively in the accessory sex glands. Moths do not store measurable quantities of juvenile hormone if their accessory sex glands are removed shortly after adult eclosion.
